Vegetable summer top dressing can choose chicken manure
In summer, the greenhouses are generally ventilated day and night, and the possibility of ammonia burning the vegetables after the application of chicken manure does not exist. Considering the advantages of fertilizer nutrients, chicken manure should be preferred for top dressing. However, the following points must be noted in the application: The application amount and application method should be scientific and reasonable. When chicken manure is used for top dressing, it can generally be applied with water, and it is appropriate to apply 200-300 kg per acre. A one-meter square cement pool can be built at the entrance of the greenhouse. A small mouth is left at the side of the pool. When the application is carried out, the chicken manure is poured into the pool. The chicken manure is directly washed out from the small mouth with a water pipe, and the water flows into the vegetable pot. It should generally be administered in the morning. Before the chicken manure is applied, it must be fully decomposed. A large pit can be dug outside the shed. The chicken manure is poured and covered with plastic film. After 20-30 days, the chicken manure can be fully decomposed. It is also possible to use a biological decomposing agent such as the antibacterial 968, and the decomposing effect is better. Note that the application of chicken manure with other fertilizers is rich in organic matter and good in fertilizer efficiency, but there are also some shortcomings, that is, nitrogen, phosphorus and potassium are relatively less. Therefore, attention should be paid to the application of potassium fertilizer in the application, especially in the prosperous period of the solanaceous vegetables. The potassium content is large, and 8-10 kg of potassium fertilizer can be mixed per mu when chasing chicken manure.
