Matters needing attention for fertilization of eggplant in summer

High temperature in summer, vigorous growth of eggplant, high yield, so there is a large demand for fertilizer, at this time are picking, while fertilization, is the key to obtain high yield. And in summer eggplant fertilization should pay special attention to a few points, the following and Xiaobian to have a look.

1. It is not suitable to apply nitrogen fertilizer.

Eggplant grows strongly in summer, when vegetative growth and reproductive growth go hand in hand, plant growth and fruit development need adequate nutrients, and more nutrients are needed. At this time, it is not suitable to apply nitrogen fertilizer, nitrogen fertilizer itself can promote plant growth, if partial application of nitrogen fertilizer will make plant vegetative growth stronger than reproductive growth, resulting in excessive growth of plant stems and leaves, fruit can not absorb enough nutrients and affect development, the emergence of small fruit, weak fruit and abnormal fruit phenomenon, seriously affect the yield and quality, resulting in huge economic losses for farmers. Therefore, it is necessary to mix phosphorus and potassium fertilizer reasonably, apply phosphorus and potassium fertilizer for 2-3 times in the full fruit period, and it is best to use ternary compound fertilizer, so as not to meet the needs of eggplant growth and fruit development, so as to improve yield and quality.

2. Avoid flushing with water.

Many farmers have the habit of applying fertilizer with water, this method can not be said to be wrong, in the crop seedling stage, this fertilization method is very good. However, in summer, with high temperature and high temperature, nitrogen fertilizers, especially ammonium carbonate, are very easy to decompose and recover. Ammonia produced by decomposition will not only reduce fertilizer efficiency, but also easily cause ammonia poisoning in plants. Therefore, in the application of urea and ammonium carbonate and other fertilizers, we must adopt the method of ditch application or hole application, at the same time, reasonable and deep application according to the soil conditions, so as to avoid fertilizer residue in the tillage layer, which is easy to cause soil salinization.

3. One fertilization should not be too large.

Eggplant has a great demand for fertilizer in the full fruit period, but in the high temperature environment, a small number of fertilization methods should be adopted to keep in mind that the amount of fertilizer applied at one time is too large, so as not to cause excessive plant growth, which is disadvantageous to yield and quality. Generally seven days topdressing once, each time the use of urea 10-15 kg per mu.

The above is the introduction of eggplant summer fertilization precautions, hope to help you, want to know more related knowledge, please follow us.
