Questions and answers on fertilization and weeding of cotton covered with plastic film
Recently, Ding Libang, a 75-year-old farmer from Shuqiao Village, Wuluo Town, Yunmeng County, Hubei Province, called me and asked if it was feasible to change the nutrition bowl to transplant seedlings to plastic film mulching cultivation this year. The answer is now given.
Q: can plastic film cotton use chicken manure as base fertilizer?
Answer: the application of chicken dung as base fertilizer must pay attention to several points: first, chicken manure should be fully mature; second, it should be applied before covering the film; third, the application amount should not be less than 1500 kilograms per mu; fourth, because chicken dung contains a certain number of weed seeds, we should pay attention to the control of weeds.
Q: is it necessary to apply other fertilizers after applying chicken manure?
Answer: it is necessary to apply inorganic chemical fertilizer after adding chicken manure. Generally speaking, 30 kg of compound fertilizer with high content or 50 kg of compound fertilizer with a content of about 25% should be applied per mu, and 10 kg of potash fertilizer should be applied. Only in this way can we achieve the combination of organic fertilizer and inorganic fertilizer, slow-acting fertilizer and quick-acting fertilizer.
Q: when is the best time to apply herbicides?
A: the application time is usually before the cotton is sown or before the plastic film is covered after the cotton is sown. However, it should be noted that the soil moisture in the cotton field must be sufficient, and only the soil moisture herbicide can fully infiltrate into the soil tillage layer and improve the weeding effect.
Q: what herbicides should be used?
Answer: Rasol and Duer are selective pre-budding amide herbicides, which can be applied before cotton sowing. Jingshande and Gengcao Neng are stem and leaf treatment agents of internal absorption and transmission after seedling, which can be used after the emergence of cotton or weeds.

Storage technology of sweet potato
A, sweet potato storage problems easy to occur sweet potato in storage during the easy occurrence of cold damage, germination and decay. Sweet potato is thermophilic and afraid of cold and humidity. The storage temperature is 10~14℃ and the relative humidity is about 80%. Below 10℃, cold damage easily occurs, and sunken patches appear on the epidermis, resulting in decay. Sweet potato has no physiological dormancy period. If the temperature is high (15~20℃), the relative humidity is above 85%, and the ventilation is not good, it will germinate at any time. Germination consumes internal nutrients and makes it inedible. Sweet potato skin thin,

New Technology of Cotton Field Management
1. Early shovel and trip: the management of cotton field highlights an early word, and the means to promote early development of strong seedlings are early shovel, multiple shovels, increase ground temperature, strong roots and strong seedlings to promote early development. 2. Topdressing: topdressing 10ml 15kg after setting seedlings, 20m 25kg after budding. 3. Fine pruning: cotton pruning is the key to increasing cotton production. Usually hit the top on July 5-10, and hit the top on July 15-20, in line with the principle of unequal branches from time to time. The number of segments of fruit branches according to the requirements of the variety
