The disease of cotton seedlings must be managed

This year, many cotton experts and technicians emphasized the appropriate late planting of cotton, which will be sown after April 20. However, "Heavenly God" prefers to joke: April 22 to early May, several rainy days, the lowest temperature dropped to 8 ~ 11 °C, in the April 8 ~ 13 seeding seedlings can be, but the seedling disease serious; The emergence rate of cotton planted before and after April 20th was significantly reduced, and seedlings were cut off in varying degrees, and seed replanting was imperative.
For the current actual situation, the author proposes the following:
First, it is necessary to carry out cultivator and loose soil in time to disperse the wet and increase the temperature. For high-humidity cotton fields, it is best to use iron wire to loosen the soil at the root of cotton seedlings.
Second, the main diseases of the seedling stage are anthracnose, blight, and root rot, and 80% of anthraquinone may be used for 500 times, 500% of 50% carbendazim, or 70% of thiophanate-methyl 700 times. 10 million units of agricultural streptomycin 5,000 times, or 80% ethyl allicin 1000 times, etc., mixed, alternate spraying 2 to 3 times, the effect is good. At the same time, the addition of 0.5% urea and 0.3% potassium dihydrogen phosphate is more effective.
Third, for the lighter cotton field, the pruning varieties can adopt the method of “retaining two plants” and “retaining three plants”. Conventional pruning varieties can adopt simplified cultivation methods of preserving leaf branches and removing axillary buds. Fourth, for lack of seedlings severe ridge broken cotton fields, we must promptly adopt on-demand replanting, pay attention to on-demand to stagger the original cotton seedlings or lines, select the early-maturing spring cotton varieties, make up before and after May 10; then select the summer Broadcasting varieties, replanting on May 15-30.

According to Professor Hu Xiaosong, Ph.D. supervisor of the School of Food Science and Nutritional Engineering, China Agricultural University, Instant Noodles are often criticized by people who think eating is not good for health mainly for the following reasons:
First, high fat content, because most of the instant noodles are fried way to dry the noodles. However, Professor Hu pointed out that compared with French fries, hamburgers and other instant noodles in the fat content is not very high, with an average of about 16% -18% of fat, of which 11% are palm oil, that is, Human health beneficial vegetable oil, and a hamburger in an average of about 30% of fat, nearly twice as much as instant noodles.
Second, contain certain additives. Professor Hu said that when it comes to additives we talk about change, I think it is not conducive to the health of the material, which is the concept of a misunderstanding. The food industry can not do without thickeners, stabilizers and other additives, the country allows the use of, are strictly tested to prove harmless to the human body, we can rest assured that consumption.
Third, many people are concerned about the problem of acrylamide. Professor Hu pointed out that all starch-based foods in the high-temperature cooking (over 120 ℃) will produce this carcinogen, therefore, there are french fries, instant noodles, there must be.
