In the past, when the fields were camped in Jingyuan, the overall situation was that the land was vast and sparsely populated, that is, the "wide township" often mentioned in the Tang Dynasty books or legal decrees, with few people and many barren fields, so the top priority was to recruit manpower to reclaim the wasteland. Therefore, when Gao Yue was in Baili City, he promoted the "intercropping method", that is, to divide the land into two pieces, one for winter wheat, one for corn, and beans and buckwheat in between.

However, in Xingyuan Mansion in Liangzhou, the situation has undergone great changes, several counties in the Hanzhong region, the population is far denser than in the northwest, and the fields that originally had complete water conservancy have been occupied by the people's fields, vocational fields, and some other fields"Multiple cropping".

Multiple cropping is to plant two (or even three crops) of different crops, such as rice and wheat, in turn on the same field according to the different seasons of crop growth and harvest.

In this way, you can use the limited land to get the maximum amount of income.

However, there are different types of rice, and the sowing period can be divided into three categories: early, middle and late, after the double confirmation of theory and practical experience, Master Ming Xuan told Gao Yue: in Xingyuanfu rice-wheat mixing, the production cycle of early rice and middle rice are in conflict with winter wheat, so it is most appropriate to take late rice and winter wheat to double crop a year.

Of course, Gao Yue now also knows that the early rice and late rice in ancient times are actually different from the early rice and late rice in the modern context. Early rice and late rice in the modern context are more distinguished by the growth cycle, the short one is called early rice (90-150 days), and the long one is called late rice (180-200 days). In ancient times, it was more distinguished by the sowing season, and the early rice was planted, and the late rice was planted.

Therefore, when the Baicao Army of Xingyuan Mansion went out to fight, the state soldiers and the families of the Baicao Army had begun to sow the seeds of winter wheat on the boundary of the low tide of Shanheyan and Chiyaguan in September and October last year.

After May of the following year, the wheat can be harvested after maturity, and the rice seeds will be soaked before the wheat harvest, and the late rice will be hurriedly replanted at the same time as the wheat harvest, and after four or five months, after the late rice is mature, the winter wheat can be planted again, and the cycle will start again and again, which is to mix rice and wheat with two crops.

In addition, in this arrangement, Gao Yue and Master Mingxuan still have a lot of painstaking efforts, that is, they can effectively "avoid taxes".

What, can farming also avoid taxes?

That's right, and listen to Gao Shaoyin's narration:

The two tax laws of my Tang Dynasty are like this, two taxes are collected in summer, and Hu dou rice is harvested in autumn, the latter just perfectly covers the maturity period of late rice, that is, Gao Yue in Xingyuan Mansion's military tun, only in accordance with the regulations, before the end of autumn, pay three percent of the late rice into the warehouse, charge two taxes Hu Dou rice to the Beijing Division, in addition to pay one-third of the grain in the field of the jurisdiction of the territory to the Jingshi Yushitai do not store (the reason will be said later), the rest of the rest of the rice except for the net worth, can be included in the Xingyuan Mansion Chiya warehouse reserves.

Therefore, Gao Yue said in the Xingyuan Mansion that he wrote the "Persuasion of the Soldiers and Civilians in the Whole Territory of the Mansion to Plant Wheat", if you plant wheat, the court and the government "do not collect their endowments, do not pay them rent, whether it is one stone, ten stones, all belong to themselves, and the people get all the benefits", which is the origin of the wheat can avoid taxes.

This is even stronger than the previous camp in Jingyuan, at that time, because the camp was presided over by the imperial court branch division, no matter what was planted, it had to be handed over to a fixed proportion to the degree branch division inspector. The Shannan West Road, where the Xingyuan Mansion is located, is the same as other Fang towns, and the income is divided into three products, and the goods that go out to be offered must be given to the imperial court, and the rest are all under the control of the military government (Xingyuan Mansion is now also a small shogunate) and prefectures. The greater the benefits of this development, the more you will gain.

In addition, the price of wheat is higher than that of rice and corn, which is really very profitable.

However, after this article was published, the rural people of Xingyuan Mansion, regardless of whether they were rich or poor, did not respond very much, and Gao Yue had long noticed that the people of Xingyuan Mansion were very insensitive to advanced science and technology and systems, and they were full of the psychology of being rich and peaceful. When he built the sub-city, wharf and shipyard before, many wealthy families in the city did not believe it, but now the Hanchuan River is unimpeded by land and water, and the merchants are like shuttles, and this group of people knows its benefits.

However, Gao Yue is not in a hurry, the people are not active, I will implement it in the military tun first, as long as the military tun can get a big sweetness, the people will naturally follow suit.

At this time, when Gao Yue and the others walked to the road in front of the field, they looked at it with great eyes, and finally saw clearly how Master Mingxuan coordinated the contradiction between the two crops and water when the rice and wheat were mixed.

That is "high wheat planting, flat rice".

Dig the soil barrier high first, it is for the "high boil", between the two sections of the high boil naturally form a soil ditch, this is the "boil", first use the boil to attract the water in the canal, properly irrigate, and wait until the wheat is planted on the high boil, that is, cut off the boil, the floating water and the water in the soil layer are drained clean, to create a wheat favorite high cool and arid environment, this is the "high boil wheat";

After the wheat is ripe and harvested, the high boil is dug and flattened, and filled in the kiln, so that the field changes from high to low, and then the water is stored in the diversion canal, and then the rice can be planted on it, which is called "flat rice planting".

Therefore, the scene of the mountain and river weir seen by Gao Yue and others, the high boils of the pieces, like a chessboard, are vertical and horizontal, very beautiful, and they are all wheat seedlings that are preparing to be jointed, like green waves, clothed with the beautiful white lan in the mountains of Xingyuan Mansion.

As long as there are two rounds of late rice, the salinization here can be completely improved, because rice is the most salt-killing.

In the fields, the Baicao Army, the state soldiers, and the Huaixi soldiers were mixed but not chaotic, and their families also drove the calves bought from the Xifan Mutual Market, and worked hard with the iron-bladed farm tools trained by the Chenggu Iron Officials.

Since the Tang Dynasty peace talks, the mutual markets in the areas of Jing, Yuan and Long have risen suddenly, on the one hand, the vigorous import of Xifan, coupled with the vigorous domestication of the attached party items in various states, the price of calves has been low and low, and Xingyuan Mansion has purchased a large number of them as animal power.

But Gao Yue was still not satisfied, so he called the former King Pu's idle officer, and now Sun Tongxuan, the pastoral supervisor of Xingyuan Mansion, selected familiar people from the Huaixi soldiers to set up a "mule workshop" and began to breed mules, horses and mules or donkeys and mules, the former can be used for military or ploughing the fields, and the latter can be used to pull carts.

Now Sun Tongxuan can be developed, originally he was a third-class poor household, since listening to Gao Yue's words, just to serve the king of Pu got thirty horses of various colors of cloth, and now he has learned the knowledge of livestock, and after becoming a pastoral supervisor, there are fourteen pieces of money for food and clothing in January, not only in Xingyuan Mansion to govern the house, but also married the daughter of a post chief, and now this day can take off.

With Sun Tongxuan's example, the 3,700 landless poor households in Xingyuan Mansion who were in the lower third class were all eager to try, and they were all arranged by Gao Shaoyin.
