After counting several times in a row, Qin Chuan was a little puzzled, he remembered that when Wang Jizong wrote the letter, he asked for one stone of jade wheat, five stones of sweet potatoes and twenty stones of taro, a total of twenty-six stone seeds, and only eighty taels of silver.

But now, there was a hundred stones of new grain in front of him.

Just when he was puzzled, Wang Jizong raised a letter from the Yangzhen Hai Dart Bureau to him, and said with a smile: "Chief steward, Mr. Zhou has given twice as many good seeds. ”

"No wonder." Qin Chuan suddenly realized, "This Mr. Zhou is a good person, I have to thank him when I have the opportunity in the future." ”

"Mr. Zhou is a student of Xu Ge Lao, Jizong has asked him for knowledge, his knowledge is endless, it is a rare mentor and friend, I heard that Jizong wants to promote new grain varieties in Lou Fu and even Jingle, Mr. Zhou gave twice as many good seeds, so that Jizong for him to promote more new grain, in order to fulfill the long-cherished wish of his mentor Xu Ge Lao."

"Oh, it's time to promote it."

Qin Chuan said with a smile as he opened a hemp bag, took out a potato from it, and ......

Compared with the potatoes that were the size of the fist at every turn in later generations, this potato is too small, only the size of an egg, about the same as a mule and horse bell, no wonder it will be called a potato in the future.

Small size means low yield, coupled with drought, severe cold, barren land and other reasons, the output is far less than the three or five thousand catties of later generations.

According to Wang Jizong, he tried planting for two years, and worked hard in the most fertile and well-irrigated fields by the river, and the highest yield per mu was only seven stones, and in the barren and arid land, the yield per mu was only four or five stones.

It stands to reason that the yield of four or five stones is already higher than that of any grain at this stage, but the problem is that at least one stone of seed is needed to plant one acre of taro.

You must know that if today's situation of disasters continues year after year, the grain yield per mu in the north is only one or two stones, and they are reluctant to let the peasants take one stone of grain and sow it in the land.

Sweet potatoes are slightly better, they can be planted with seedlings, but they are not planted every season, and sweet potatoes are easy to feel uncomfortable when they eat too much, and they are stinky and smelly, which is really not good as a staple food.

Coupled with the inherent conservative thinking of the common people, Xu Guangqi's progress in promoting new grain in the north was very slow, and no one wanted to grow grain with high yield.

Yumai is a lot of species, this thing was introduced to Guangxi as early as the Jiajing period, and spread to other provinces, and now most provinces in the south are cultivated.

However, there are still very few people in the north who cultivate this thing, because it is not as cold and drought tolerant as millet and millet, and it is easy to fail when it is affected by natural disasters.

From the perspective of science and progress, Qin Chuan admires Xu Guangqi.

From the perspective of making a fortune and getting rich, Qin Chuan wanted to help him.

In the future, the crops in Lou Fu and Jingyou will be dominated by new grains, and the fertile fields on the riverside or the fields with sufficient irrigation in the downstream of the reservoir will be mainly wheat, potatoes and beans, and the two-year three-cropping system will be rotated, in which wheat and potatoes are the staple food, and beans can not only be used as green manure, maintain the fertility of the land, but also improve the diet, and provide concentrated feed for the horses.

On the slope of insufficient irrigation, millet, millet, corn, and sweet potatoes should be planted according to the situation, and some beans should be sandwiched by crop rotation, intercropping, intercropping, etc.

Among them, sweet potatoes are more varied, although this thing eats too much and loves to fart, but it is still a treasure all over the body, sweet potatoes can be made into sweet potato powder, dried sweet potatoes, etc., potato vine and potato leaves can be eaten by people and can be used as feed, add some bran or soybean cake into it, it is the best concentrate.

"Chief steward, Mr. Zhou also wrote down Xu Ge's dung pill making method and the ashes dipping rice seedling method."

While Qin Chuan was carefully examining those seeds, Wang Jizong happily walked over and handed the letter to him.

"Dung Dan?"

Qin Chuan was a little curious, took the letter and took a closer look, only to see that it was densely covered with fly-headed calligraphy, with various famous cities written on it, as well as many numbers, which dazzled him for a while.

Wang Jizong shook his head next to him and sighed: "The method of dung pill is Xu Ge Lao to alchemy painstaking study for many years, before finally developed, its fertilizer effect is far better than manure, a bucket can be used as a big dung ten stones, ashes dipping seedling method can also improve the planting seedling rate, it is a good recipe for cultivation." ”

After looking at it carefully for a while, Qin Chuan nodded thoughtfully.

This dung pill is actually the most primitive chemical fertilizer, which is mixed with human and animal feces, animal corpses, hairy blood, arsenic, sulfur, etc., and then put into a clay jar or buried in a soil pit, and then taken out to dry and mash after decaying, it becomes a chemical fertilizer.

The letter said that any animal carcass and entrails could be used, birds and mice, and even locusts.

As soon as he saw this, a big net appeared in Qin Chuan's mind, netting the army of locusts that covered the sky and the sun, and the fat ones were roasted and eaten, and the thin ones were all buried in the pit as fertilizer......

Well, this method is feasible, you have to weave a net in advance, and when there is a locust plague one day, bring 18,000 people to the net and come back to make fertilizer, and the number of locusts is not enough.

"Ming Zhao, Lou Fu's bumper grain harvest depends on you."

Qin Chuan was in a very good mood, put his arm around Wang Jizong's shoulder, and said with a smile.

Wang Jizong didn't break his hand either, but smiled: "The chief steward and rest assured, Jizong will go all out, just one potato, I dare not say that the yield per mu is seven stones, and five stones are indispensable." ”

"Okay, that's good, hehe, one day I'll go to Taiyuan for a trip, get you a mink coat back, and go to enjoy the snow with your lady."

"Hahaha, okay, then Jizong is better to be respectful than to obey his fate."

"Ahem...... Come on, move all these seeds into the cellar, so that you can survive, and cover the cellar with more thatch, so that these baby bumps don't freeze. ”

"Okay."

Lao Huang on the side ran into Zhuangzi with big yellow teeth, handed over two hundred soldiers from the ten-fang battalion, each with a sack, and carried a hundred stone seeds into it.

Wang Jizong also followed, and he had to arrange for the storage of seeds and the means of covering the cellar to keep warm.

Qin Chuan put up his soft fur collar and entered the Zhuangzi leisurely.

As soon as he entered the doorway, there was a sudden sound of horses' hooves outside, and a sentry was hurrying back.

In the distance, the sentry shouted: "Chief steward, there is a detachment of men and horses from ten miles to the east, about fifty or sixty people, slowly coming towards our Zhuangzi." ”

"Huh?" Qin Chuan turned his head, "What's the way?" ”

"I don't know, Tian Lao Wu and I wanted to come forward to ask, but we were almost shot by a white-faced boy, so I hurriedly ran back to report the news, Tian Lao Wu was staring at them."

"Yo, who is so bold as to dare to go wild on the territory of this patrol adult?"

"Come on, let's go out and have a look."

"Okay."

Soon, Qin Chuan led fifty tigers and leopards and one hundred and ten square camps to gallop towards the east.

It didn't take long for him to run into the gang.

There are more than 50 people, all of them strong and well-equipped, most of them are the same and neatly dressed, and all the sturdy Mongolian horses under the seats look like the homes of some large families.

The leader was a slender white-faced scholar, dressed in a short body, with a square scarf in his hair, and a small horned bow in his hand, looking at Qin Chuan coldly from a distance.

Behind the white-faced scholar, there were three other little scholars with the same fair skin and slender figures, one of whom was dressed in a wide Confucian robe, looking soft and weak.

"Big boss, which family's son-in-law is this, he looks so handsome."

An old bandit from Jiuji Mountain looked at the little scholars with his eyes hooked, and sighed.

The grinning old yellow grinned and took over with a smirk: "Hehe, big boss, do we have to kidnap a few ladies to go back?" ”

Qin Chuan smiled angrily: "You old man, I heard this, we really lack so many Mrs. Zhai." ”

The old bandit of Jiuji Mountain on the side was puzzled: "Big boss, what did you say to Lao Huang?" So where did Mrs. Zhai go to take it away? ”

Qin Chuan smiled again and said, "Those white-faced little scholars are not some sons, but a few girls. ”

"As expected, it should be the daughter of a certain big family, and the lady of the village is here to send the lady of the village to your big boss."
