The Ming battleship repaired for three months, and finally regained its combat strength, and by the way, the bird ship was replaced with a composite sail - the main mast was a crosssail, and the other two masts were triangular sails.

Not only that, but the ship's guns have also been increased to 100!

A treasure ship, two bird ships, and thirteen Portuguese ships were transported to Malacca for trade with cargo, the first time that a Chinese fleet had sailed long distances against the wind.

Man Zheng needs to go to Guangzhou first to find Zhan Ruoshui, who is about to expire.

Zhan Ruoshui is Wang Yangming's best friend, the second-generation successor of Baisha Xinxue, and the founder of Ganquan Xinxue. Wang Yuan's mind study is more inclined to Ganquan mind science, but it is getting farther and farther away from Yang Ming mind science.

Zhu Houzhao asked Wang Yuan to recommend diplomats, and Wang Yuan recommended Zhan Ruoshui. Whether it is public or private, it is very suitable, and Zhan Ruoshui has also been to Annan before.

So, Zhan Ruoshui and a member of the Ministry of Rites, went to Malacca to negotiate on behalf of the Ming Dynasty.

In the blink of an eye, it was the beginning of July, and the corn in the school field began to tassel, and Wang Yuan went to inspect the situation again.

The person in charge of the trial planting of new crops is none other than Xing Tai, a student of Wang Yuan in Shandong. This guy posted big-character posters everywhere to slander Wang Yuan, and was caught by Yuan Da for squatting for several days, and finally became a physics disciple in a daze, and led the entire family to support Wang Yuan in Linqing to control the water.

Xingtai is really not the material for the imperial examination, and after a few years of repeated failures, he is still a sour talent. He is not good at physics, mathematics is a mess, so he simply follows Wang Yuan around, just waiting for one day to ask for an oblique official.

This time the Portuguese brought new crops, and Xing Tai saw that Wang Yuan attached great importance to it, so he took the initiative to ask Ying to be in charge of trial planting.

The son-in-law of the local gentry, who has never even touched a hoe, actually wants to engage in agricultural experiments?

Xing Tai pointed to the experimental field and said, "Sir, according to the comparison of multiple batches and types of planting, we have now gained something. ”

"In detail." Wang Yuan said.

"The first stage of corn growth I call the 'breeding period'. The second stage I call the 'three-leaf stage' because there are only three leaves at that time. Corn has to be fertilized and watered in the 'three-leaf stage', just like a baby leaving breast milk, and the care must be more delicate. In the 'three-leaf stage', the corn generally does not grow well, the corn stalks are thin and short, and the leaves are occasionally yellow. ”

"Yes, I have a heart." Wang Yuan nodded in approval.

Xing Tai also said: "The stage after the 'three-leaf stage', which I call the 'jointing stage', is like the jointing of bamboo, and the height increases very quickly. At this time, just the opposite of the 'three-leaf stage', corn can resist drought, but it is afraid of too much water. This year's rain was average, and the corn that was not watered much during the 'jointing period' grew the best, while the corn that was watered the most during the 'jointing period' was directly waterlogged to death in two ridges. ”

Wang Yuan was particularly satisfied and praised: "You have done a good job." ”

Xing Tai said modestly: "The disciple does not understand agricultural affairs, but uses physical methods in crop trials. ”

Wang Yuan asked again: "What about the problem of interplanting?" ”

Xing Tai recounted: "There is no problem with interplanting for the time being. Now, we have corn, peanuts, and sweet potatoes in clear farming, as well as two or two sets of seeds, and three sets of farming. At present, only one problem has been found, the field after interplanting must be topdressed, otherwise the fertility is not enough to grow badly. ”

This problem is not big, because even in later generations, unless a large area is mechanized planting, corn is mainly farmyard fertilizer, supplemented by chemical fertilizer, and the demand for chemical fertilizer for corn is not too strong.

Xing Tai added: "Because it involves land fertility, the students read a lot of agricultural books. It is recorded in the "Qi Min Yao Shu" that the rotation can be used to restore the soil fertility, and if the interplanting consumes too much soil fertility, the students plan to experiment with other crops in rotation. ”

Wang Yuan naturally encouraged again.

Wang Yuan is also half a bucket of water, and the spacing between corn plants he gave can actually be slightly denser.

If Xingtai continued to observe the experiment, he would be surprised to find that the yield of corn interplanted with soybeans was even higher than that of the clear seed, and the corn cobs were fuller and the corn kernels grew larger.

When it comes to photosynthesis, corn and soybeans can be planted at the same time, which can increase the utilization rate of solar radiation energy by 15% to 20%.

The two crop species are in the same field, and the difference in height creates a ventilation corridor that increases the supply of carbon dioxide. When light hits the lower part of the corn plant, soybeans also form a sunlight scatter, which is exactly what the crop needs, and the quality of the light is better than no scattering.

Therefore, after interplanting, the corn yield will increase significantly, but the soybean yield will decrease slightly.

This kind of intercropping technique was very popular in the hills and mountains of New China. Later, I gradually stopped interplanting because the degree of refinement was too high, and the energy spent on serving one acre of land was equivalent to planting several acres of land alone. It's better to work in a factory for a few months and earn more corn and soybeans.

As for planting corn on ridges, it is to prevent waterlogging, and too much rain will waterlog the corn!

And Wang Yuan didn't know that peanuts could also be used for interplanting. Together with sweet potatoes, corn and soybeans, these cross-cropping intercrops can act as a rotation and restore soil fertility naturally.

Anyway, everything is in the process of exploring, and it is not good to take the criminal examination examination, nor can it be done in physics, but it seems that playing planting is really promising.

An agronomist who has never touched a hoe is quietly born in the land of Daming.

Let's talk about breeding again, the Indians have been cultivating corn for thousands of years, don't you know how to breed when you are a family? The corn seeds obtained by Spain have been cultivated by the Indians for 3,000 years, and people built their country on that thing!

Modern improved varieties of corn are mainly to increase the functions of disease and pest resistance, waterlogging resistance and drought resistance, and one plant with multiple fruits.

Wang Yuan walked around the experimental field, some corn grew gratifyingly, and some corn withered and wilted, which was planted in different ways.

Wang Yuan said to Xing Tai: "As long as you spend three or five years to study these crops thoroughly, I will ask Your Majesty to restore Sinong Temple, and at least give you a diagonal seal official of Sinong Temple!" ”

"Sinong Temple?" Xingtai was a little confused.

Wang Yuan explained: "At the beginning of the founding of the Ming Dynasty, there was Sinong Temple, which was the same as Dali Temple, Taichang Temple, and Honglu Temple. Got it? At least give you a temple masa. ”

"Thank you, teacher!" Of course Xingtai understands, and he is overjoyed, Sicheng is a positive five products!

There may be many opponents to streamlining the department, but there is little resistance to increasing the department, and the revival of the agricultural development agency is more in line with the appetite of the scholars.

It is most convenient and effective to quickly promote several new crops and their intercropping methods throughout the country, and to set up special new departments. Excuses can be found casually, and the restoration of the ancestral system of the Ming Dynasty is the reason, Sinong Temple was originally set up by Zhu Yuanzhang.

However, the Ministry of Household Affairs may oppose it, because after the abolition of Sinong Temple, most of the functions and powers were transferred to the Ministry of Household Affairs and the local political department. The local left and right sides participated in politics and the chief officials at all levels undertook the work of Sinong Temple, but they were only superficial in persuading farmers and mulberries.

Wang Yuan was also too lazy to seize power, and after the re-establishment of Sinong Temple, he mainly played a role in advocating tandem and sent Beijing officials to cooperate with local officials to develop agriculture.
