1. New background
I went to Yiwu a few days ago and saw many trees planting along the way. It didn't attract my attention. Spring is the solar term for planting trees. A friend of mine asked me if I want yew? There are two to thirty years old. I was shocked, I can't afford it, it's too expensive! He said: Don't talk about money. Because his friends have planted a lot, they are now going to "return the forest to farmland", so they have to deal with it within a time limit and turn the orchard into farmland. When I heard it at the time, I didn't quite believe it. Wasn't it "returning farmland to forest"? I hurriedly checked "Du Niang". Sure enough, the country has a policy. If you retire, you will retire, and there are rewards.
It is right to think about it. The central government has made three orders and five applications: to ensure 1.8 billion arable land. This involves the basic supply of food. We have about 1.4 billion people. We must ensure that we are self-sufficient in food! Otherwise, under the complicated international background, if our country is to remain invincible, it must have grain in hand and not panic in its heart. When the epidemic broke out last year, didn't some neighboring countries ban food exports?
It can be seen from the above that our arable land must be secured. I also saw a boundary marker on the road, which was engraved with: Permanent Basic Farmland Reserve. But in the periphery of the city, it is not uncommon that when you see rice fields or wheat fields taking pictures, rows of towering buildings stand out in the background. Whether it is legal or compliant? There is so much land, the land that can be used for arable land is not necessarily equivalent? In particular, plantable food is even more precious. Seeds and land are one of the seven key tasks of the country this year. The seed has to be his own, and that "Monsanto" has done so many ugly things, isn't it just changed? The land must be used for arable land, no matter what you build? The red line cannot be broken. This is related to the safety of the country and the safety of the people. You must not slack off at any time!
2. New application
Academician Jiang Fengyi has a metaphor for LEDs, which is: less heat, more light. This is quite appropriate for plant lighting. Heat can increase the temperature, and light can play a role in photosynthesis. Make the best use of everything, no waste at all. Plant lighting has become more and more popular in recent years, especially when the new crown epidemic is spreading, the housing economy has risen in response to the epidemic. For example, indoor cannabis cultivation in North America and the use of plant lighting, especially LED light formulas, have made related manufacturers a hit. Fire again. Of course, there are also vegetables, fruits, and even valuable Chinese herbal medicines. I always feel, what is missing? Whenever I talk about it, I don't agree with it. 79 yuan per catty of lettuce, is there any promotion value? That's just for the luxury crowd, isn't it still lettuce in essence?
Until one day, when I saw the people in Taiwan grow wheatgrass, I realized that plant lighting can still solve the problem of rations for cattle and sheep in winter. Did this grow by accident? After the smart Hangzhou people saw the photos I took, they invited me to see them on the spot. It was really "green"! It is also said that in Southeast Asia, it is popular to use fresh wheatgrass to squeeze juice.
It happened that I had been to Xinjiang during the Spring Festival. When the information about plant lighting to cultivate wheatgrass was told, they were very excited. They didn't need to mobilize or call, and they immediately heard the wind. Xinjiang needs it too much. It’s cold. Some cattle and sheep need to be slaughtered for money, and some are not available for winter. It is said that cows eat well, eat grass and retain roots. Where's the sheep? It’s ugly to eat. (Do not check in for the sheep of the year of the year, and you must eat the root. Maybe the sheep is clever and the roots are more nutritious. But no matter how wide the prairie is, it can't stand the toss of sheep. If it eats the roots, how many years will it take for the grass to regenerate?
3. New synergy
There is no shortage of capable people who do LED lighting. A few days ago, two full cabins were tried out, and 288 kg of wheat was put in one cabin, and the output was 1.5 to 1.7 tons, which took only 6 days. It should be such a large amount of input and output, I have never seen a report (maybe I am ignorant). Facts speak louder than words, plant lighting really has a magical effect, from wheat to grass is generally six times the harvest. That night, I also squeezed fresh wheat straw into juice. I actually drank three cups. The light and delicate fragrance is better than wine. I who did not sleep well, I slept beautifully until dawn. It was the effect of alcohol or wort. It's not very clear.
Fresh grass came out, but the problem followed, I can summarize it as follows:
1. For the post-processing of fresh wheat straw, some friends said: simple, just feed it directly to cattle and sheep! This is the following 2.
2. Cattle and sheep are not for what to eat, it has to suit the taste. Another friend said: Simple, just ferment it. Is it that simple? This is a subject. Otherwise, how can the feed company make a fortune?
3. The choice of seeds? How to choose a good species and do a good job of 1>6 output is a knowledge.
4. The price-performance ratio of wheat straw and other feeds is far from enough to talk about social value, it must have economic value. Only in this way can it be generalized and benefit more herders, and only then will more consumers have a sense of gain. You think, there is a plant cabin next to each herder's bag. What a dreamy picture it will be!
5. The plant box is 6.6 meters long ✘2.8 ✘3, which is just matched with a 17.5 meter truck, which can be assembled and installed on site. It will be done overnight as long as it is connected to electricity and water. Is there a more reasonable way to make it high-quality and inexpensive, so that the herdsmen can afford it?
6. What is the nutritional value of wheat straw?
7. Intelligent control and networked remote control of the plant cabin?
8. One cabin of the plant cabin is multi-purpose, and the herdsmen have to eat vegetables too! If successful, the lives of herdsmen can be greatly improved, and the same will be true in winter.
9. The plant cabin can be triggered to the plant factory, which will be an all-round and three-dimensional one again. This will bring much benefit to saving land. At present, the greenhouse cultivation is mostly rolling land, which is too wasteful of land. I think this should be a trend. Plants should go upstairs and small high-rise buildings should be laid out. The Israelis invented drip irrigation, and we can also discover three-dimensional planting, making full use of the interactive use of natural light and artificial light.
The above are just nine points. In fact, there are still too many problems to be discovered and solved!
4. A new starting point
In 2021, the new starting point for the second centenary, LED people should not be merciful, and we must strive to be new pioneers. Plant lighting and even plant factories require the participation of experts in agriculture and other fields, which is also a cross-border collaboration.
