"Your Majesty, this thing is non-toxic, can regulate the spleen and stomach, nourish and nourish, and help to prolong life, so it is also called 'longevity fruit' in the local Inca, and has the reputation of 'meat in vegetarian food', and its nutritional effect is comparable to eggs and meat!"

Li Yuntian knew that Emperor Xuande, Zhang Fu and others were very surprised by peanuts, so he explained methodically, "There are various ways to eat this thing, eat it raw to remove phlegm, cook it to moisten the lungs and relieve cough, and fry it to produce phlegm." ”

"In addition, this thing can be squeezed for oil, and eating it can strengthen the brain and body, which is very beneficial, and it is really a first-class product." As he spoke, Li Yuntian peeled off a peanut shell, took out the two plump peanut kernels inside and put them on the palm of his hand, and said to Emperor Xuande, "Your Majesty, please see, this is the fruit in the shell, the minister has tasted it, it is mellow and refreshing, and it is unique." ”

The reason why peanuts are longevity fruit is because traditional Chinese medicine believes that the function of the spleen and stomach is very important, peanuts can regulate the spleen and stomach, so that the function of the spleen and stomach can be enhanced, then people will naturally grow stronger, and at the same time, it can also slow down aging.

Everyone present looked at the peanut kernel in Li Yuntian's hand suspiciously, looking a little incredulous, no one would have thought that this peanut would have such an effect.

"Uncle Zhenwu, what's in the other two bags?" Emperor Xuande felt that this peanut was very interesting, if it really had the effect that Li Yuntian said, then the physique of the people of the Ming Dynasty would undoubtedly be strengthened, he glanced at the two peanut kernels in Li Yuntian's hand, and then asked with interest, wondering what surprises Li Yuntian would bring him besides peanuts.

Li Yuntian knew that neither Emperor Xuande, nor Yang Shiqi, Zhang Fu and others had the intention of tasting the taste of peanut kernels, so he threw the peanut kernels in his hand into his mouth, opened the next small bag while chewing, and took out a cone-shaped object covered with golden hard particles all over his body, and there were some red whiskers on the top of the object.

"Your Majesty, this thing is called corn, which is not only suitable for warm and humid climate, but also dry crops, not only the grain yield per mu is high, but also the leaves and stems can also be used as fodder, whether it is the northern plain or the southwest mountainous area can be planted, so that the cultivated land area of the people has been greatly increased."

Li Yuntian raised the corn in his hand and introduced it to Emperor Xuande in a deep voice, "Your Majesty, it can be rotated with winter wheat in the Yellow River Valley and the northern regions with a long frost-free period, and it can be harvested twice a year to improve the harvest. ”

Yang Shiqi, Xia Yuanji and others couldn't help but show a look of surprise when they heard this, if what Li Yuntian said was true, corn was high-yielding, precocious and did not have high requirements for the planting environment, then its appearance would undoubtedly make use of the vast mountains, hills and sandy lands in the Ming Dynasty, greatly increasing the area of cultivated land, thereby increasing the total grain output and solving the people's food rations.

"Your Majesty, this thing can not only be cooked and eaten, but also ground into flour." In the end, Li Yuntian summed up and put the corn and peanuts on Emperor Xuande's table with the imperial meal.

Emperor Xuande stretched out his hand and pointed at the peanuts and corn, Jin Ying hurriedly went over and took them over and handed them to Emperor Xuande, Emperor Xuande put them in his hand and looked at them carefully, and his eyes fell on the last bag in Li Yuntian's hand.

Under the gaze of everyone with great interest, Li Yuntian took out the object in the third bag, which was a red-skinned object the size of a melon, which looked heavy.

"Your Majesty, this thing is called Yam, also known as sweet potato, barren soil, drought tolerant, grain per mu can be more than 1,000 catties, and its stems and leaves can be used as feed."

Raising the red-skinned thing in his hand, Li Yuntian said to Emperor Xuande in a deep voice:

"As far as the minister knows, this thing is suitable for growing in hot and humid places, I can grow it in the south, and the climate in the north is dry, and the winter is cold, as long as the collection of potato seeds is perfected so that it can survive the cold winter, then it can be planted in the north."

"More than 1,000 catties per mu?" Hearing this, Xia Yuanji couldn't help but say in surprise, one mu of high-grade fertile land in the Daming Huguang area is only 500 catties of high-grade rice seed raw grain per mu, and the sweet potatoes in Li Yuntian's hands can exceed 1,000 catties, which is really incredible.

Raw grains, also known as "natural grains", refer to the general term of unprocessed grains, such as rice, wheat, corn, soybeans, sorghum, millet, broad beans, peas, etc., which usually have a complete shell or protective tissue, and are higher than finished grains in terms of insect resistance, mildew resistance, and storage resistance.

Corresponding to the raw grain is "finished grain", also known as "processed grain", refers to the raw grain after processing to remove the husk or ground into powdered grain, such as rice, millet, flour, etc., due to the different quality of raw grain varieties, the conversion rate of raw grain into finished grain is between seventy and eighty.

Li Yuntian did not exaggerate, according to the records of Yu Guangbi of Dageng Zhi County, Jiangxi Province in the 13th year of Qianlong, the sweet potatoes under his jurisdiction could be harvested three or four thousand catties per mu.

Shandong political envoy Lu Yao also recorded in the "Sweet Potato Record" written 50 years ago that planting sweet potatoes per mu can get thousands of catties, which is several times better than planting grains.

"Uncle Zhenwu, how is the harvest of this thing this year?" Yang Shiqi thought of another question, and then asked in a deep voice.

As soon as he opened his mouth, he immediately made everyone present look at Li Yuntian, Li Yuntian has let people plant sweet potatoes in Hukou County this year, and there should be a yield.

"According to the report obtained by the lower officials, the yield per mu of inferior fields is 1,000 catties, the yield of medium fields per mu is 1,200 catties, and the yield of high-grade fields per mu is 1,500 catties."

Li Yuntian had already dealt with it, and replied calmly, "Since sweet potatoes contain a lot of water, they can be converted into raw grain at a ratio of three to one, and you can get 330 catties of raw grain per mu in Xiatian, 400 catties of raw grain per mu in Zhongtian, and 500 catties of raw grain per mu in Shangtian." ”

However, because sweet potatoes are mainly made of starch, they are very low in protein, so they are usually used as an accompaniment and are not suitable as a staple food.

Because sweet potatoes can be grown in different seasons, especially in the south, they can be used for disaster relief, Xu Guangqi's "Complete Book of Agricultural Administration" said, "The people of Fujian and Guangzhou rely on it to relieve hunger, and its benefits are very great."

Sweet potatoes are suitable for cultivation in certain mountainous or sandy areas and can help the poor to make ends meet, and there is literature that says: "Three meals a day, rice for the rich, porridge and sweet potatoes for the poor".

Sweet potatoes are often used as staple foods in relatively poor areas, and people would not use them as staple foods if there were better choices, but they can be used to make zuò starch, make wine, and use them as feed, etc., which is an excellent supplementary food to solve the food rations of the people.

With a bang, as soon as Li Yuntian's words fell, a small commotion broke out at the scene, Yang Shiqi, Zhang Fu and others couldn't help but be taken aback, and they didn't care about Emperor Xuande on the side, whispering about the yield of sweet potatoes, feeling incredible.

"Your Majesty, I am the first to plant sweet potatoes, improve the planting conditions, and after accumulating planting experience, the yield will be improved." In the whispered discussion of the ministers, Li Yuntian couldn't help but raise his voice, and said in a deep voice to Emperor Xuande, who was stunned.

"Uncle Zhenwu, this matter is very important, and there must not be the slightest mistake." At this time, Xia Yuanji came back to his senses first and solemnly instructed Li Yuntian, looking a little excited.

He was in charge of the household department, so he naturally knew what Li Yuntian meant to Da Ming by peanuts, corn and sweet potatoes, but because this matter was too sudden and beyond his comprehension, he was a little suspicious that Li Yuntian was exaggerating.

"Shaobao, the officials in front of the emperor don't dare to speak, everything they say is true." Li Yuntian handed the sweet potato to a waiter on the side, arched his hand at Xia Yuanji, and replied in a deep voice.

"Congratulations to the emperor, as long as these three kinds of agricultural products are cultivated in my Daming, they will not only strengthen the people's physique, but also greatly increase their rations."

Seeing Li Yuntian's calm expression and resolute eyes, Qianyi, who was standing beside Xia Yuanji, immediately arched his hand at Emperor Xuande and said loudly.

Obviously, peanuts can strengthen the body, corn increases the cultivated area, and sweet potatoes increase grain production, which will enable the people of Daming to fill their stomachs and strengthen their physique, which is of far-reaching significance.

As the saying goes, the people take food as the sky, and the first thing the county kings of the past dynasties have to face is the problem of eating the people, if the people are hungry, then the country will definitely fall into turmoil.

In addition, the population of Daming has exceeded 100 million, with the existing arable land and crops, it is obvious that it can no longer meet the food needs of the population to continue to grow, and Li Yuntian has just solved this biggest problem, which will surely make Daming more and more prosperous and rich.

"Congratulations." Hearing this, Yang Shiqi, Zhang Fu and others bowed their hands to Emperor Xuande and congratulated in unison.

As Li Yuntian said before, he entered the palace this time to report the good news to Emperor Xuande, and at present, it seems that the matter he reported is indeed a great joy that has to be deducted, and it will have a far-reaching impact on the Ming Dynasty.

"Uncle Zhenwu, when will these agricultural products be planted by the people?" In the congratulatory voices of the ministers, Emperor Xuande's mood was invisibly much better, he peeled off a peanut shell in his hand, took out the peanut kernel inside and played with it, and asked in a somewhat urgent tone.

"Your Majesty, the minister is going to let the military households of Jiangwutang try to plant for two years, find out the habits of these agricultural products, and then promote them to the whole country."

Li Yuntian pondered for a moment, then bowed his hand to Emperor Xuande, and said in a loud voice, "In view of the fact that the military households of Jiangwutang are now gathered in the Gyeonggi area, the minister hopes that the Xiaowu Army can recruit a group of sergeants from the military households in Jiangnan, Central Plains, and Southwest China to ensure that they can be tried in all regions of the country. ”

"Okay, I'll do what you want." Emperor Xuande didn't think about it when he heard this, he agreed to it, he went to the camp on the outskirts of Wutang to inspect twice, and was very satisfied with the military appearance and momentum of the Xiaowu army in the camp, and wished that there were more such elite divisions in the Ming Dynasty.

"Taishi, you are the first assistant of the military pavilion, this matter will be handed over to your military pavilion to handle, this matter is related to the future national fortune of my Ming Dynasty, we must let the trial plant be completed!"

Subsequently, Emperor Xuande turned to Zhang Fu and solemnly instructed.

"The emperor can rest assured, the minister will handle it properly." Zhang Fu bowed his hand to Emperor Xuande and replied loudly.

He was looking forward to what Li Yuntian had said, wondering if peanuts, corn and sweet potatoes were really as miraculous as Li Yuntian said.

"Uncle Zhen Wu, in your opinion, is our army a war or a peace?" Then, Emperor Xuande put down the peanut kernel in his hand and asked Li Yuntian quietly, his expression becoming stern.

After Li Yuntian's congratulations just now, Emperor Xuande thought of the current matter, so he asked Li Yuntian's opinion again.!^!
