"The director of the Institute of Mechanics said that it is possible to produce 40,000 catties per mu, and it is impossible for us to achieve this goal before we have completed the gene technology tree, and the yield per mu of the highest yield of sweet potatoes in the first generation after detoxification (Note 1) is 10,000 catties. Sun Chang asked Fan Lun, the newly arrived production supervisor of the Southwest Seed Company.

"No one knows that none of the seeds we sell can produce more than double the existing crops. At present, the highest yield of Champong rice is only 400 catties per mu, which cannot be compared with the yield of 900 catties per mu of hybrid rice in our experimental field.

At present, in our experimental field and the mastery area of our partners, the yield is sweet potato (the average of the experimental field is more than 1000 kg, higher than the average level of partners, more than 2000 kg, and the high yield reaches more than 5000 kg, in short, it is a yield artifact, life-saving food in a famine year), potato (high-yielding such as the Huangshui Valley trial planting of Yuanyou four-year mu yield is 1793 kg, the average is about the same as sweet potato, but sweet potatoes are more likely to produce 10,000 catties of this kind of sky, and it is also a divine object), Corn (about 600 kilograms, high-yielding such as Yongxing Junlu reached more than 800 kilograms), sorghum (many areas are two seasons, the total output is about 700 kilograms, wine-making sorghum quality is good but the yield is low, the overall average yield per mu is lower than corn), rice (about 460 kilograms, Yuanyou four years Sichuan rice yield per mu is 466 kilograms, relatively stable, although the experimental field is constantly increasing, but ordinary farmland can not be as good as the experimental field advanced technology, etc., and it is sown rather than the planting of the experimental field, After hulling, the rice yield is 75%-80%), wheat (400 kg), millet from Yongxing Military Road (300-400 kg, but because of the more hulling weight, the rice yield is about 70%-75%), barley (mainly used for winemaking, the yield varies greatly in different regions, and some areas of Huainan East Road reach more than 500 kg, with an average of about 250 kg) barley (also a kind of barley, with a yield of about 150 kg-200 kg per mu, due to the separation of inner and outer glume shells, the grains are exposed, So this yield is very real, all that is produced is grain, and some production areas can reach more than 400 kilograms). "All in all, sweet potatoes and potatoes are sacred objects, but they are not as suitable for food as the back, the second echelon is corn, sorghum, rice and wheat, and it is also the most important four kinds of grain in our country, of which sorghum is suitable for planting in relatively few places, and corn is not suitable for planting all parts of the country, and it depends on land fertility and chemical fertilizers greatly, otherwise the yield is very low, so rice and wheat are the most important grains. The third echelon is millet, barley, and barley.

Although we produce a lot of food on our turf, we will not put it on the market to hit the price. In the future, corn and potatoes were mainly used for the production of feed and starch industries (wine, chemicals, pharmaceuticals), and wheat and rice were used for storage and export. Miscellaneous grains and other millet, barley, etc., were hoarded.

It is no exaggeration to say that we are the world's leading breeders in breeding and field management, and we are the masters of the most advanced technology. Although it is not possible to sell seedlings to the private sector on a large scale, it is still necessary to sell some high-yield staple crops and guide the planting of cash crops that are in high demand for partners in response to the requirements of partners. Some time ago, Zhou Lijian, Qian Jin and Wu Qi asked me to secretly send people to Hainan Island, that is, Qiongzhou Island, where Zhuya is located, to plant rubber trees.

The main task in the future is to continue to do a good job in the work of the eight-character constitution. It is difficult to realize the myth of 10,000 catties of yield per mu without one of the various elements of improved seeds, water conservancy, fertilizers, pesticides, soil improvement, field management, mixed agriculture, and tool improvement. We should pay close attention to the construction of water conservancy facilities, improve the irrigation system and the grain storage and processing system, and share a part of it to the government and other rich peasant landlords. Let me ask you, is it possible for the large-scale fertilizer and pesticide factory invested in Lizhou Road last year to start mass production in the third quarter? Fan Lun had to smile bitterly and said, "The headquarters only approved the budget and funds of five agricultural machinery factories and fourteen technical schools in Sichuan, and we still have to find our own way to find a way!" As for the fertilizer plant, which can only produce 500 tons of potash fertilizer and 200 tons of phosphate fertilizer per month, this is the result of Fei Lao Niubi's strength in the Jiaoguoluo area to ensure that the raw materials are sufficient. You don't have to think about nitrogen fertilizer, several masters of the pressure vessel project team are so tired that their hair is all gray and they haven't built a qualified reaction tower. The synthetic ammonia plant has not yet been established! Our polymer organic chemical industry has no shadow, how can there be pesticides, use soil pesticides to make do with a few years and then see if there is any hope to use pyrethroid advanced pesticides. This is not what you mean, if you have been opposed to the development of highly toxic organochlorine, organophosphorus, organofluorine, organosulfur, organocopper and other compounds as active ingredients of a class of pesticides, to avoid the source of food safety problems, adhere to one step in place, directly on the plant surname pesticides, microbial pesticides project, Dean Zhou of the College of Chemical Materials can be so headache? ”

Note 1: Most crops, especially those produced in the form of nameless propagation for a long time, will be infected with one or more viruses or virus-like viruses through casteless breeding, and pathogenic bacterial infection may not necessarily cause crop death, and many viruses may not even show visible symptoms. However, with the increase in the number of surnameless reproduction, the accumulation of viruses also increases, resulting in a large reduction in crop yield, quality decline, and aggravation of diseases. Currently, there is no ideal drug to cure virus-infested crops. The distribution of viruses in crops is very uneven, and the meristem at the tip of the crop stem tip does not contain viruses, or contains little virus. Peel off the plant obtained by cultivating the stem tip growth point, and then carry out virus detection, prove that it can be rapidly propagated without virus, and the test-tube seedlings produced in this way are detoxified seedlings, and the detoxified seedlings of various crops are used for production, and the yield can generally be increased by 30%-50%. Since potatoes, sweet potatoes and cassava are all kept in the form of surnameless breeding, the problem of seed potato degradation is very serious once infected with the virus. Currently, 25 viruses are known to susceptible to potato, 14 to sweet potato, and 12 to cassava. Studies have shown that detoxified potatoes can increase yields by 30%-100% and detoxified sweet potatoes by 30%-70%. Due to the prevalence of cassava infection, the yield of detoxified cassava will also increase significantly.
