Last Updated: 2024/11/22, 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: several points must be paid attention to when using chicken manure as base fertilizer: first, chicken manure should be fully mature; second, it should be applied early before mulching; third, the application amount should not be less than 1500 kg per mu; fourth, because chicken manure contains a certain amount of weed seeds.

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.
