Jiang Anrao brought back a lot of high-quality rice seeds from Chu and Southwest Counties.

These rice varieties have been cultivated and optimized for many years, although they are not as good as the hybrid rice of later generations, but they are already good seeds in the case of limited scientific and technological level.

Her idea was to start planting rice in the spring and wheat in the winter in the Hanzhong region of Qindi. In this way, we can achieve three crops in two years, and one more season of grain can have more grain reserves.

Calculating the time, it is not too far from the Battle of Changping.

In today's war, there are only a few factors for victory, and only when there are abundant food reserves can we have the last laugh.

So Jiang Anrao has been running around since he came back, in order to survey the soil and learn more about the local climatic conditions.

However, when they heard that Jiang Anrao was going to plant two crops for two crops, those local old farmers shook their heads when they heard it!

"That can't be done, that's not possible! Since ancient times, how can there be such a thing as planting two crops in Qindi. If you say yes, planting a season of wheat, and then harvesting and planting some yams, mung beans and the like can barely be achieved. Rice and wheat, so where is it! ”

None of the farmers here have ever planted rice, and some people don't even know that rice needs to be planted first, so they think that they can just throw it in the soil and bury it.

Whether it can be done or not, you will know after trying it.

The population and land are all in Jiang Ruoyang's charge, and Jiang Anrao mobilized all the Mo families and agricultural scholars who could be found in the Qin realm to select a site in the Hanzhong area, and to choose land suitable for growing rice.

In the Qin and Han dynasties, a step refers to the distance of each foot on the left and right feet, and the length of one foot in the Qin period is about 23 centimeters now.

The Qin State decided to take 240 steps as one acre. According to statistics, the cultivated land in the central Qin and Han dynasties has now reached nearly 500 million mu!

Since Jiang Anrao had already planned to plant, he had to start preparing in advance. It is now September of the 39th year of King Qin Zhao, and although everything will not start until the next year, Jiang Anrao needs to use the time before the start of spring sowing to train people in various places first.

The people of Hanzhong have never grown rice. Therefore, it is necessary to teach the farmers to prepare the land for later use, and then teach them to fatten, raise seedlings, and explain the things they will encounter when planting rice, as well as the timing of adding water and releasing water.

Wait until spring planting to teach them how to plant rice in advance.

Because it was the first year of the experiment, it was not possible to plant all the cultivated land for two seasons, and there were not so many rice seeds, so Jiang Antao led people to run for two months, and selected 100,000 mu of cultivated land according to the amount of 20 catties of rice seeds per mu.

Among them, the ratio of upper, medium and inferior fields is 5:3:2.

It is also true that there are too few people who can grow rice in Qindi, and no matter how much land there is, Jiang Anrao will not be able to run away with people alone, and no matter how he runs, it is impossible to run all over the places in a day or two.

And sometimes the farming time waits for no one, just like the time of tillering fertilizer, it is too late for one more leaf to come out, so the first attempt, everything must be within the controllable range.

At this time, the fertilizer almost relied on farm fertilizer, so Jiang Narao told people and animals to keep manure and even urine. After all, urea is an indispensable fertilizer for rice planting. Of course, in fact, she didn't say that the farmers were reluctant to throw it away.

Jiang Anrao implemented many new farming techniques and farm tools in Qindi, but after the family went to Xianyang, Jiang Anrao's energy was on the Mo family's side. In recent years, it has vigorously developed Mohists.

This sudden return to the field is quite unaccustomed.

When King Qin Zhao and Wei Ran happened to mention Jiang Anrao's big moves during this period of time, they also sighed.

I think that back then, the edict to Jiang Yang was because he took a fancy to Jiang Rao's ability, but now when I look at it, this Jiang Rao has not been committed to farming for many years. Fortunately, the Mo family is also working on improving the weapons of the Qin army.

But then, King Qin Zhao also began to have another doubt.

Jiang Rao suddenly engaged in farming with such fanfare, why?

This question was not asked by her until the end of the year, when Jiang Anrao was almost busy, and when she returned to Xianyang, she went to meet Gan Mi.

"There's no reason for that, but I feel more and more that food is important. If the two countries are at war, unless they can defeat each other with one blow, they can only fight for attrition.

The Qin State has been fighting for so many years, and the long-term victory is also related to the continuous supply of the Qin army.

Now that the Qin State is constantly fighting, if there is not enough reserve food, if the Qin army is stalemate with other countries one day in the future, won't it be a loss?

So, I want to grow more food under the existing land. ”

The farming technology can no longer be advanced, so we can only work hard from the number of times.

When Gan Mi heard this, he also thought so.

After saying this, the two also chatted a little.

Jiang Anrao has been running too many places for so many years, and everything he has seen and heard is unknown to Gan Mi, it is rare to see it once, and he must ask this and that.

Although Gan Qi is married, she still has a lively side in her temperament, and Yingzhu is very good to her, so she can still retain some of her temperament back then.

Gan Mi actually had a pregnancy, but when she was almost eight months pregnant, she accidentally fell and the child flowed out, she was still a boy, the child did not survive, and she was also completely injured this time, and there was no possibility of giving birth in the future.

Seeing that Jiang Anrao had been married for many years and had not given birth to a son and a half daughter, Gan Qi did not ask the reason in detail, but thought that it was similar to her. was afraid that Jiang Anrao would be unhappy, so the two rarely talked about children's related topics.

Jiang Anrao was left by Gan Mi for two days in Anguojun's mansion, just because Gan Mi wanted to hear her talk about what she had seen and heard, and Gan Mi was driven away by Gan Mi when Ying Zhu appeared in the past two days, and Ying Zhu had to touch his nose and leave.

However, Jiang Narao couldn't stay here all the time, so he said goodbye to Gan Mi for two days and returned to Jiang's house in the tree.

Qin now uses the legislation of the Shang period, and Jiang Anrao's family regards December as the month of wax according to modern customs, but in the Shang calendar, and in today's Qin State, November is the end of the year, and December is the first month.

On the first day of December, the king would go to the heavens to worship his ancestors. And the people will send the plague god on the last day of November.

In the history of the previous life, fireworks should have only begun to come out in the Tang Dynasty. But the Chinese burned bamboo and burst firecrackers for a long time.

Qindi is not extravagant, and the common people do not sacrifice to the sky, so for the people, sending the plague god on the last day of November is also a big festival. But in the past, there was no such thing as firecrackers in Qindi.

Jiang Anrao returned to Xianyang, and he didn't have to run around, so he became an idler at home again. So she thought about it, so she went to cut bamboo outside the city with Wang Yun and came back, and did an experiment of throwing firecrackers into the brazier, and it was really crackling and very lively.

You can hear it all over the house!
