It's August, and it's getting closer and closer to harvesting rice.

Mo Changfeng has to spend a long time in the rice field almost every day, and he is comparing the most prominent rice plants, that is, the rice with the best growth and the best development.

In fact, Mo Changfeng has been paying attention to it all along, because he has to think about next year's rice breeding, and this is one of the projects he is responsible for.

"Teacher Mo, these rice plants you selected are two to three centimeters taller than ordinary rice plants, the ears of rice are also forty to seventy millimeters long, and there are ten to thirty more grains on them."

Not only Mo Changfeng is paying attention to breeding rice plants, but also the professors of the Provincial Academy of Agricultural Sciences and the graduate students of the Provincial Agricultural University who came to participate in the seed production process in batches are also paying attention to these, and those graduate students respectfully call him Mr. Mo.

"Well, these rice plants are the excellent rice plants we have been selecting, which usually grow a little faster, grow better, and produce more grains, which is what we will focus on cultivating for next year's seeds."

Mo Changfeng is more modest, but he has also studied in college, so he can talk to these students and get along with them, so he explains his choice to them.

"Then in this process, there will definitely be some eliminated, right? Only those that are left over at the time of harvest can be used for next year's breeding, right? Some graduate students asked.

"In fact, to cultivate excellent rice seeds, we must also follow Darwin's theory of evolution, and the survival of the fittest. Only the best rice plants that grow in the end are our final choice. Mo Changfeng nodded and said.

Mo Changfeng didn't know much about other theories, but for the excellent rice plants he selected, he would usually water more heaven and earth aura to make them grow better.

Moreover, as long as it is an excellent rice plant selected by Mo Changfeng, it is good to set up a sign next to it, so that everyone can pay attention to it and not operate them in the usual management.

At the beginning of the selection, these rice plants did not have many obvious advantages compared to the surrounding ones, but as they grew, especially with Mo Changfeng's careful management, they gradually grew better and better, and eventually became a sample of the standing rice group.

"Dad, tomorrow you can organize people to harvest the grain seeds first." On August 8, Mo Changfeng found Zhou Caifu and said that the large-scale harvesting of rice would take place within two or three days.

"Okay, there are more villagers who have signed up, you can pick some people to do it first tomorrow." Zhou Caifu nodded and said that this year's rice harvest will be completed by all manual harvests, so every household in the village has someone to sign up to participate.

"Let's find ten younger ones first, and we can finish it in half a day." Mo Changfeng selected a group of young and middle-aged laborers, such as Mo Changhong and the like.

Whether it is the excellent seeds selected by Mo Changfeng or other rice planted with grains, the speed of mechanical harvesting will definitely be faster, but the loss will be much more.

Therefore, this year, Murakami decided to use manual harvesting, that is, to cut off half of the ears of rice, transport them to the drying field by tricycle, and threshing them directly with a threshing machine.

At the same time, this is also to preserve the late rice, because the late rice will be distributed to the villagers, so the villagers are eager to sign up to participate in the rice harvesting, and can also earn 200 yuan a day.

Beginning at 5:30 a.m. on August 9 and ending at 10:30 a.m., under the guidance of Mo Changfeng and the village cadres, 10 villagers harvested the best batch of rice that had been marked before, threshed it with a machine, dried it in the dam of the village office, and dried it all after 5 p.m.

"There are eight hundred and twenty-eight pounds of seeds." After being processed by the windmill, the remaining clean grain seeds are only more than 800 catties, but it is enough for 500 acres of paddy fields to breed.

"These grains should be put in the storage room in the village, and you should pay attention to moisture and fire prevention." Mo Changfeng is still very satisfied with these grains.

Next, when it was time to harvest other rice, the Provincial Academy of Agricultural Sciences brought down five experts and professors, and brought twenty or thirty graduate students to help, and at the same time took charge of the measurement work.

More than 80 villagers are divided into eight groups, each of which is responsible for harvesting rice from a paddy field, transporting it to different dams for threshing and drying by specialized people.

Several experts and professors and the graduate students they brought with them were scattered to eight dams to help with threshing and drying, because the weather has been close to 40 degrees recently, so as long as the sun is not particularly thick, basically the millet can be dried in a day.

The villagers start working at half past five in the morning and finish work at half past nine, because it gets hot after nine o'clock, and the temperature in the rice fields sometimes exceeds 40 degrees.

After 6 p.m., when the millet in the dam had been dried and processed by the windmill and put into the warehouse, the villagers continued to harvest the rice, got it back and threshed it and piled it up in the dam, and dried it again tomorrow.

"Professor Li, the yield of this field has reached 750 kilograms per mu."

"There is another field that yields 758 kilograms."

"The field with the least yield also has a yield of 745 kilograms per mu."

A group of graduate students also participated in the final harvest despite the hot weather, and also weighed the paddy in each dam in detail and recorded it.

Because the millet of each paddy field is dried individually, it is relatively easy to calculate the yield in the end, just divide the weight of the sun-dried windmill by the number of acres of the paddy field.

The output data was directly reported to the leadership desk of the Provincial Academy of Agricultural Sciences that night, and at the same time reported to the leaders of the province and the Dahan National Academy of Agricultural Sciences, which attracted great attention.

Because the speed of manual harvesting of rice is slow, more than 80 people can harvest an average of 80 mu per day, so it takes seven or eight days to completely harvest.

However, since the third day, there have been experts and professors from the National Academy of Agricultural Sciences and other provincial academies of agricultural sciences, and even Yuan Gong's closed disciples and national academician-level experts have come to inspect with their disciples.

Every time a group of experts arrives, they will participate in the drying and final processing of the paddy despite the hot weather, and weigh and record the final harvest.

"Sure enough, there is a production of about 750 kilograms, which is simply incredible." Yuan Gong's disciple said excitedly.

At present, the yield of hybrid rice researched by Yuan Gong can reach 6,780 kilograms per mu of single-cropping rice, while the yield of double-cropping rice in some places in the south can reach 1,500 kilograms per mu.

However, the scope of application of this kind of double-cropping rice is limited, and it cannot be popularized throughout the Han country, so there are still some limitations, and it has been planted in the southern provinces, which has also greatly increased the grain output and made a great contribution to solving the food problem in the Han country.

The excellent rice researched by Mo Changfeng is suitable for planting all over the country, and it is also suitable for planting in the south, which can be one-season rice or double-cropping rice.

Judging from the yield of double-cropping rice planted in the village last year, it has almost reached about 1,400 kilograms per mu, but that is when there is no professional management of late rice.
