How to apply fertilizer to grow vegetables?

Applying fertilizer when growing vegetables can not only promote the growth of vegetables, but also reduce the occurrence of diseases and insect pests to a certain extent. But how to fertilize growing vegetables is a problem worth paying attention to.

How to apply fertilizer to grow vegetables?

1. Base fertilizer

The application of base fertilizer is generally combined with soil preparation, and it is generally best to slowly release organic fertilizer, such as cow manure, sheep manure, chicken manure, cow manure and sheep manure. In addition to slow fertilization, it can also play the role of loosening the soil, the method is very simple, sprinkle fertilizer on the soil, and turn over the soil, so that the soil and fertilizer can be combined.

two。 Plant fertilizer

The seed fertilizer is supplemented in the case of insufficient base fertilizer, but it can not be applied if the base fertilizer is sufficient. If you need to apply seed fertilizer, generally use fully mature organic fertilizer or quick-acting chemical fertilizer, the application amount should be less. All kinds of quick-acting chemical fertilizers, completely mature organic fertilizers (such as cake fertilizer, poultry manure, etc.), biological fertilizers, trace element fertilizers and so on can be used as seed fertilizers. There are three methods of application:

(1) seed dressing: mix a certain amount of fertilizer and a certain amount of seeds evenly, and then sow the seeds.

(2) seed soaking: soak the seeds with a certain concentration of fertilizer, then remove the seeds to dry and sow them.

(3) dipping in the seedling root: mix biological fertilizer, micro-fertilizer and a certain proportion of organic fertilizer into paste, dip it in the seedling root and then transplant.

3. Topdressing

Topdressing actually depends on the situation of vegetables, adding some fertilizer to make vegetables grow faster and better, for example, leafy vegetables grow to more than three or four leaves, in order to speed up their growth, we can top fertilize once at this time. At this time, we can choose bean dregs or sesame oil dregs. We should pay attention to soaking and fermenting in advance, while watering vegetables, add these fertilizers, so that fertilizers can be quickly added to vegetables. The goal of accelerating growth has been achieved.

4. Foliar spraying

Fertilizer and pesticide can be mixed and sprayed, which can not only meet the supply of nutrients, but also control diseases and insect pests.

Generally speaking, fertilization for growing vegetables generally includes base fertilizer, seed fertilizer (not available), topdressing and foliar spraying, while the specific type and amount of fertilizer need to be determined according to the actual situation, and can not be generalized.
