Daming: Stealing Chen Yuanyuan at the beginning

Chapter 194 Vermicompost, Glass Greenhouse Experiment
It is foreseeable that with the invention and manufacture of the breech-loading flintlock gun, the combat effectiveness of the army of the Ming Dynasty will usher in a huge leap.

Li Cunming and Bi Dengfu were very excited, and Tang Ruowang also said with emotion: "After the Renaissance, various trends of thought emerged in Europe, ushered in a knowledge explosion, and people have a deeper understanding of the world. But I have to say, so far it represents The world's most advanced technology was still in the Ming Dynasty, it's amazing!"

Li Cunming smiled and said: "Mr. Tang, our Huaxia has the advantages of Huaxia, and you have the uniqueness of the West. Among other things, at least in terms of navigation technology, astronomy, etc., as well as the construction of the scientific system, my Ming Dynasty has already been in the middle Falling behind."

"I often feel anxious. The ships of your Westerners ride the wind and waves to the far east, while most of my people's understanding of the world is still on land. What makes me even more troublesome is that I have to fight the Jiannu Tartars , I don’t know when it will be the head.”

"I am worried, I am worried that I will fall behind one step, one step behind!"

Tang Ruowang said: "Your Majesty has a long-term vision and extraordinary insight, and he will definitely accomplish great things."

Li Cunming smiled slightly and said seriously: "I can only focus on expelling the Tartars now. If this cannot be completed, it will be impossible to talk about the stars and the sea, the power overseas, and the world hegemony."

"Speaking of the Tartars, after the drastic change in Kaifeng, I clearly realized that the national power of the Ming Dynasty is far from being able to support my dream of recovering the rivers and mountains. There is a long way to go, and our strength has not yet reached the point of crushing the Qing Dynasty! I want to What to do is to seize the time to enrich the country and strengthen the army, restore social production, and prosper the social economy."

"The most important thing is the problem of food production. Although the southern provinces have vigorously promoted the cultivation of potatoes and corn, the food in the national treasury is still stretched. Bi Dengfu, let me ask you, can you find a good way to increase food production? "

Bi Dengfu said: "Since the imperial court moved south, I have deliberately paid attention to agricultural affairs. I have benefited a lot from reading "Essential Art of Qi Min", "A Complete Book of Agricultural Affairs", "Tiangong Kaiwu" and other books. Your Majesty should actually consult Lord Song Yingxing. , Compared with Mr. Song, I am an unlearned and unskilled person."

"However, since Your Majesty asked, I would like to share some superficial opinions. To increase food production, there are no more than two approaches. One is to select high-yielding crops; the other is intensive cultivation, among which the use of agricultural fertilizers is very important."

"I will mainly talk about the use of agricultural fertilizers. According to rough statistics, there are various types of agricultural fertilizers in China, including: manure, cake fertilizer, dregs fertilizer, bone fertilizer, soil fertilizer, mud fertilizer, gray manure, green manure, straw manure, etc. There are also various miscellaneous fertilizers. Each has its own advantages and disadvantages, and each has its own uses, so we cannot generalize."

Li Cunming nodded, thinking to himself that our country has been a big agricultural country since ancient times. After thousands of years of development, by the time of the Ming Dynasty, the agricultural technology must be far ahead of the world.

Judging from Bi Dengfu's introduction, farmers are mainly using organic fertilizers at this time, which is also determined by the production technology, and there is nothing wrong with it.

To invent and mass-produce chemical fertilizers in the Ming Dynasty is probably a dream.Even in modern society, the production of chemical fertilizers is an important indicator of a country's industrial level. Many countries have not yet achieved self-sufficiency in chemical fertilizers in the 21st century.

Hey, can you change your mind and find alternatives to chemical fertilizers?

At this point, Li Cunming smiled and said: "Bi Aiqing, I have a way to grow alfalfa, and mobilize the people to collect bat and bird droppings, and mix it with plant ash to use as a new type of fertilizer."

The components of chemical fertilizers are actually nitrogen, phosphorus, and potassium. Alfalfa can fix nitrogen, bat and bird droppings contain a lot of phosphorus, and plant ash contains potassium.

Li Cunming even thought of sending fleets to Southeast Asian islands to dig bird droppings, and sending soldiers to Qinghai to dry salt and bring them back to serve as high-efficiency fertilizers.

"Your Majesty, is this method feasible?" Bi Dengfu asked.

"Try it, real knowledge comes from practice!" Li Cunming waved his hand and took out a secret recipe from his sleeve, "Bi Aiqing, have you heard of earthworm dung?"

"Vermicompost?" Bi Dengfu shook his head.

Li Cunming said: "I have a secret recipe for producing vermicompost here, you can study it. Vermicompost is known as the 'Fat King', and it can be produced with our current production technology. I look forward to your research and large-scale production. Solve the fertilizer problem."

Before humans came to the earth in the future, earthworms had cultivated the earth for hundreds of millions of years.After fermentation, various organic wastes in nature are rapidly decomposed under the action of protease, lipase, cellulase and amylase in the digestive system of earthworms, and transformed into nutrients that are easily usable by themselves or other organisms, and become vermicompost after excretion .

Therefore, vermicompost is essentially a product of nature, which can truly comprehensively meet the various needs and nutrients of plant growth, and has incredible magical fertilizer effects on plants.At any concentration of vermicompost, even very delicate seeds or flower bed plants will not be burned due to excessive amounts. The biologist Darwin once said that "there is no fertile soil except vermicompost grains."

This piece of vermicompost secret recipe was obtained by Li Cunming when he checked in in Kunming.The system father's reward is so unrestrained and far-sighted.

Bi Dengfu received the secret recipe respectfully, and saw that the manufacturing process was written in detail on it, which generally used pig manure to breed earthworms, and then used vermicompost to make vermicompost.

"It seems that I have to build a large pig farm first!" Bi Dengfu said with a smile.

Li Cunming also laughed loudly: "It's good to raise pigs. If you want to get rich, you must first build roads, raise more pigs and grow more trees!"

After Bi Dengfu put away the secret recipe of earthworm excrement, Li Cunming said on a whim, "Bi Aiqing, is there any breakthrough in glass production technology?"

Bi Dengfu said: "Reporting to Your Majesty, the Military Academy and the Academy of Sciences have invested a lot of material and financial resources. After the craftsmen's research and conclusions, the glass I produce today is indeed very sophisticated. It can be said that it has reached the point where you can do whatever you want. The production of large pieces of glass can also ensure that there are no impurities.”

"Really? Does that mean that I can build a glass greenhouse?"

"What is a glass greenhouse?"

Li Cunming thought for a while and explained in an easy-to-understand way: "Food is the most important thing for the people, but how to preserve food has been a thorny problem since ancient times, and how to eat fresh vegetables is also very troublesome. With glass greenhouses, we can eat Vegetables out of season, such as chives in winter, do you understand?"

Bi Dengfu suddenly realized: "It's almost like a fire room!"

The so-called "fire room" is a unique greenhouse in the Ming Dynasty. Like the kang used to sleep in the north, a kang was built in the room to heat the vegetable shed to increase the temperature.

Ming Xie Zhaozhe's "Wuzazu · Wubu San" records: "In the middle of winter in the capital, there are yellow sprouts and leeks, which are made from the kang in the cellar of Fushi."At that time, rich families in Beijing would build kangs in cellars. In the middle of winter, not only yellow sprouts and chives were endless, but also "other flowers and fruits, all the time", as well as peony flowers and cucumbers.

In the Qing Dynasty, the greenhouses for growing off-season fruits and vegetables were developed from the pits to the ground, commonly known as "Hua Dongzi". One end of the kang is a stove, and the other end has a large dung tank.The flowers produced are called "Tang flowers", and the vegetables are called "Dongzihuo", mainly including cucumbers, lentils, eggplants and other varieties.

Li Cunming said: "Yes, it is the same as the fire room, except that the fire room uses fire and kang to increase the temperature. The glass greenhouse is made of glass and sealed for heat preservation. In this kind of greenhouse, The crops are growing fast and lush, and the yields are high."

"I will make an idea and draw the glass greenhouse. Bi Aiqing will lead the craftsmen to start testing. Don't be anxious and explore slowly. Everything has a process. Don't be discouraged if you fail. If you fail a few times, you will learn lessons. I believe You can do it!”

"The minister leads the decree!" Bi Dengfu said with enthusiasm, and he couldn't wait to do something special.
