Those who know more about geography know that the Ryukyu Islands are a region with poor resources and poor soil. There are very few fields suitable for growing food, and the previous agriculture in this area was mainly based on sugar cane and pineapples, and it was completely unself-sufficient in food. When he was the magistrate of Ryukyu Prefecture, he vigorously promoted temperate rubber trees and diesel trees, as well as marine fish farming, kelp farming, and seawater pearl farming, which led to a sevenfold increase in the county's agricultural output value and a threefold increase in the average annual income of rural people in five years.

The agricultural conditions in Ryukyu Prefecture are already the best in the city, and even if Ximen works so hard, he mainly uses cash crops, and he still cannot be self-sufficient in grain. Although China is not short of grain now, no one has too much food, and it is always good to have a little more. Especially if it is self-sufficient in food, it is of great significance to a region.

If the Ryukyu Islands rely on traditional agricultural varieties, they can only stop all cash crops and turn all the mountainous areas into terraces, and they must also grow potato crops, otherwise it is impossible to rely on ordinary rice alone. Cash crops are an important source of income, of course, they cannot be stopped, and it is not allowed to open terraces at will in China, especially in areas with more rain and thin soil layers, it is strictly prohibited. Because in the long run, this kind of thing is equivalent to a hammer deal, it is easy to cause rocky desertification, and then it will be completely finished, and the entire land will be scrapped, and nothing can be planted, which is very not cost-effective.

But now with Mr. Wen, the world has become different. During World War I, many new varieties of crops were copied by experts from the Academy of Agricultural Sciences and began to be promoted throughout the country. Among them is a new food crop, seawater rice.

Ryukyu City is one of the first areas to be promoted, and they tried to plant hundreds of acres last year, and the results were very satisfactory, and this year they began to plant a large area.

"Xiao Liu, how is the autumn harvest of seawater rice in your village?" Before he reached the ground, Ximen Fuxue couldn't help but ask.

Liu Jinbao replied: "Mayor, we started the autumn harvest yesterday, and now we are almost a third of the harvest......

"Well, how is the yield?" Ximen Chuixue is most concerned about this, after all, the output of the experimental field and the field are two different things.

"We have all made records, the average yield per mu is more than 530 catties, the lowest is in the early 500s, and the highest is more than 570 catties......" Liu Jinbao paused and said: "It is much lower than normal high-quality rice, but it is higher than our old rice varieties in the past......

Village Chief Liu's expression was a little disapproving, because in the eyes of Chinese, who were accustomed to all kinds of high-yield crops at this time, an average yield of more than 530 jin of grain per mu was nothing, and the yield of rice per mu could be thousands of jin at will, and it was not uncommon for the yield to be more than a ton per mu. However, before the establishment of New China, this kind of inconspicuous output could only be achieved by a few fertile lands such as Jiangnan and Huguang, and the output of only three or four hundred catties was only available in many places.

"Well, that's for sure. It is true that the yield of this seawater rice is not very high, but it can be grown in seaside tidal flats, and it can be grown in saline-alkali swamps that were completely unusable before, and this is its biggest advantage. Besides, don't you think it's easy to grow?" Simon smiled. The yield of this seawater rice is not as good as that of normal rice, which he has known for a long time.

"Indeed, this kind of rice can be directly irrigated with seawater, and it can be planted on the beach by the sea without picking the ground. There is no need for cultivating, and there is no need for how to fertilize, because it is a saline-alkali land on the beach, weeds can't grow, and even weeding is not needed, so it is quite convenient to plant. Village Chief Liu also smiled. He also felt that he was a little dissatisfied, but it was already of great value to be able to plant this one on the beach.

Nandadong Island is not large, and they soon reached the slopes of the rice fields at the west gate. Standing on a high place and looking at it, I saw that about 100 meters along the coastline have been carved out into rice fields, and the fields are golden at this time, as if a golden belt has been encircled on the island. The sea breeze is blowing, the rice waves are rolling, and a burst of rice fragrance is blowing in the nose.

"Good! good!" Ximen Fuxue was so happy to see this scene that he said yes again and again.

Simon walked briskly to the rice field and plucked an ear of rice to look. The ears of rice are very full, the rice grains are relatively long, and they look a little like indica rice and some like wheat grains.

"Mayor Ximen, our village has opened up a total of 1,200 acres of new rice fields by the sea, and according to the plan of the city's expert group, these new fields are all opened along the seaside...... said village chief Liu.

Previously, these fields could not be used for cultivation. In these coastal tidal flats, seawater backs up at high tide, causing the soil to contain a lot of salt, making it difficult for crops to grow except for weeds such as mangroves and reeds. Of course, some tidal flats can be used for aquaculture, but not all tidal flats are suitable.

In the history of the original time and space, the Datu Dynasty also had the idea of transforming tidal flats into cultivated land, and they encouraged coastal areas to use tidal flats to reclaim land and expand the area of cultivated land. But the idea is very happy, and the reality is very skinny, because the reclaimed tidal flats are all saline-alkali land, and it is very troublesome to transform it into arable land for planting ordinary crops, and it requires a lot of fresh water to be washed for many years before it can be used for planting. However, due to the general lack of fresh water in the coastal areas, the high cost and low efficiency of transforming tidal flats into cultivated land made it difficult for the Datu Dynasty to expand its cultivated land through land reclamation.

And even if the land reclamation is successful, it will cause serious consequences. In practice, it is found that about 10 years after the cofferdam is closed, the area of new silt outside the embankment is equivalent to the original reclamation area, which makes the channel on the nearby sea surface shallower and narrower, affecting the function of the port. At the same time, fertilizers washed into seawater will cause serious pollution and reduce the self-purification capacity of the sea area. In the future, it will cost more money to clean up than to reclaim the land. It's worth the loss.

And now these new varieties of crops are completely different, they do not need to build time-consuming and laborious embankments to hold back the sea, nor do they need to transform the soil, plus they themselves have the function of nitrogen fixation, the root system is developed, and there is no shortage of phosphorus and potassium elements in the seaside area, and even fertilizer is saved. These crops can be planted by leveling the beach and planting them without altering the local ecology. At high tide, the water is pouring water and fertilizing them.

At this time, several tractors dragged small harvesters into the field, rumbling and harvesting, they were followed by several special agricultural vehicles, they had six tires like military vehicles, each tire was wide and large, and there were deep bumps on the tread, which was the kind of special tire that was particularly suitable for action in the field. The tires of this new type of agricultural truck can be replaced, usually on the road can be replaced with ordinary tires, but also to remove the middle pair of wheels, if you want to go to the field, and then replaced with this special tire, plus the middle pair of wheels. The removal and installation of the tires is easy and fast, and it can be done in a maximum of an hour if two people work together.

The efficiency of the harvester is much higher than that of manpower, and I can see that the rice stubble is harvested by the machine, and the golden color of the seaside is decreasing at a speed that is visible to the naked eye. The harvester did not stop all the way, and the harvested ears of rice and the straw were sent to the truck that followed by it on a conveyor belt. After filling a car, the harvester stopped temporarily, the truck drove quickly to the barn at the edge of the field, the driver moved the handle, and the cargo compartment immediately slowly lifted up, dumping the rice inside into the open space, and quickly returned to the harvester, and continued to start the next round of work.

The people in the threshing floor were not idle, they immediately ran over and carried the rice to a machine next to the threshing field. This is an all-in-one threshing machine, which can complete threshing, finishing and binding straw at the same time, with very high efficiency. Golden paddy poured out of the outlet, and bundles of bundled straw were thrown out of the other outlet.

The barn is covered with large reed mats, and the farmers use baskets to spread the detached rice on the reed mats to dry. The fields are busy. The threshed straw is also sent to the other side to be spread out to dry, these things are also useful, after chopping, they can be used as the base material for planting mushrooms, they can also be thrown into the biogas digester for fermentation, they can also be mixed with fishmeal and other things to make feed, and they can also be pressed and carbonized in the coal kiln to make straw carbon, which can be used as fuel for gas engines, pot camel machines or household fuel.

"This mechanization is good, if so much rice couldn't be dried in a few days before, now it will be seventy-seven or eighty-eight in less than an hour. A farmer said with a sigh.

"yes, it's much easier for us to do farm work now. Now the 1,200 acres of rice are almost harvested by tractors, and only the places where hundreds of acres of tractors can't go are done manually, and they are also harvested by manpower. Another old farmer said with a smile.

Dozens of people were harvesting on a tractor-driven plateau, divided into teams of four people each, three of whom were responsible for transporting rice to the field and one person who was responsible for harvesting. Instead of using a traditional sickle, the harvester pushes a man-powered harvester like a small cart. This kind of machinery is small in size, light in weight, does not use electricity or oil, and can harvest rice with a push by hand, and can harvest 0 per hour. 5-0。 8 acres of land, is 5-8 times the sickle harvest, this machine can not only harvest rice, but also wheat, sorghum and other grasses, once launched by the majority of farmers welcome.

Moreover, this kind of manpower agricultural machinery is not only the Heben harvester, but also the potato harvester, the seeder, the rice transplanter, etc., anyway, there are all kinds of mechanization. Now this kind of manpower and agricultural machinery has been sold all over the world. And these things are still modular design, if you are tired of manpower, you can also add animal power accessories, and it will immediately become animal power machinery.

The old farmer's son was also playing this, and he said with some sighs: "Is the current mechanization good, that is, ...... Hey, if I wait until my grandchildren's generation, maybe they won't even be able to use a scythe......"

The middle-aged farmer next to him laughed: "Hahahaha, old Yangtou, what's there to sigh about? Didn't the science and education film shown last month say that agricultural technology is constantly improving, and this farm tool is also constantly improving, and this sickle has not existed since ancient times. You see, my son can't even use a hoe, and now driving a tractor is not the same as farming......"

There were also people talking on the other side of the barn.

"It's unheard of to be able to grow rice on this beach...... "An old farmer held a handful of rice with an unbelievable expression on his face.

"Uncle Liu, you lost, when you just planted rice this year, you still said it was whimsical, hahaha......" The young man next to him laughed.

"Lose, lose, I lose convincingly! I am willing to gamble and lose, and when this autumn harvest is over, I will set up wine and invite the whole village to drink......" The old farmer nodded again and again.

An old farmer next to him gloated and said, "You, you deserve to lose." Don't you look at what time it is now? This holy son of heaven is in power, what auspicious rui can't come out? Don't say that it is seawater to grow rice, even if Mr. Wen and his old man say that oil can be produced in stones, I will believe ......."

The young man was embarrassed for a moment and said, "Ahem, Uncle Li, the secretary has said that this is science, not auspicious!"

"But science is also auspicious, before Mr. Wen and his old man sat in the world, how could there be these things? This is not what Xiangrui is? Besides, isn't this scientific socialism done by Mr. Wen's old man? So this is Xiangrui!" Uncle Li said confidently.

The young man was completely embarrassed, with an expression of "you said so reasonably, I was speechless".

A middle-aged man next to him leaned over and said: "But this stone really produces oil, I read the newspaper that the northeast side is refining oil in the stone, what is shale oil?" ”

"You see, as long as the Holy Son of Heaven is in power, there will be ...... good things" Uncle Li was even more proud. The young man was already on his knees......

Ximen Fuxue and others also arrived at the barn at this time, and he also heard some of the farmers' conversations, and many embarrassing words made him cry and laugh.

Like what:

"How big is this deputy mayor of Ximen?"

"It is equivalent to the old man of the former Qing Dynasty, who is a five-grade official. ”

"The officials of our new dynasty are good, but they don't look very prestigious. This Ximen Tongzhi old man went out on patrol, and he didn't even have a guard of honor. In the past, when the county magistrate went out on patrol, he had to carry a sign to avoid silence and open the way. This is the same as the old man came out, at least eight people opened the way, and there were gongs and drums, flags and so on......"

"Mayor Ximen, don't mind this......" Village Chief Liu Jinbao said with some embarrassment.

"It's nothing, the villagers didn't scold me, what can't be said......" Simon shook his head indifferently and said to the secretary next to him: "Go and measure an acre of confiscated land, harvest and see." Xiao Liu, you find someone to cooperate. ”

Liu Jinbao agreed, and hurriedly arranged for people to go.

After a while, the secretary measured an acre of land harvested, and after the threshing, it was weighed, 604 catties!

"After drying, it is generally removed6. About 5% of the water is 565 pounds. Well, this yield is not bad......" Ximen Fuxue nodded with satisfaction.

Liu Jinbao also breathed a sigh of relief, if the output that the deputy mayor personally saw was inconsistent with what he said, it would be troublesome.

Then Ximen casually smoked a few acres, and the output was more than 520 catties after conversion, and then he finally had a smile on his face. According to the yield of 530 catties per mu, the 1,200 acres of land on this Nandadong Island can harvest 318 tons of grain, and their village has only 412 people, which is more than enough. The problem of food self-sufficiency in Ryukyu City was solved.

Of course, it is not only the Ryukyu City that has solved the problem of grain self-sufficiency, but also the problem of grain self-sufficiency in many other island areas, areas near the sea, and inland saline-alkali areas with the spread of new saline-alkali crops such as seawater rice.
