Summer eggplant fertilization skills
How do you fertilize summer eggplant?
The first is to deepen the ditch. A lot of vegetable farmers have the habit of flushing with water when they are chasing chemical fertilizers. In fact, under the hot summer weather conditions, this method of fertilization is unscientific. Because, under high temperature conditions, nitrogen-based fertilizers (urea, ammonium nitrate, ammonium bicarbonate) are easily decomposed, especially ammonium bicarbonate is highly volatile. The ammonia produced by the decomposition not only reduces the fertilizer efficiency, but also easily causes eggplant ammonia poisoning. . Therefore, according to the characteristics of nitrogen fertilizer, deep ditching should be adopted. The ditch depth should be 5-8 cm. After the application, the soil should be buried in time, and the water should be poured to fully dissolve the fertilizer. Adding the fungus fertilizer will increase your chemical fertilizer efficiency. .
The second is scientific use. The demand of nitrogen fertilizer in eggplant is very large during the full fruit period, but in high temperature weather conditions, fertilization methods of â€œeat less and eat moreâ€ should be adopted. Under high temperature conditions, the conversion rate of urea after applying to the soil is relatively fast. After the plants meet their needs, the excess will be lost. Especially in sandy soils, the fertilizer loss rate will be higher. The amount of ammonium bicarbonate per acre does not exceed 20 kg. It is usually 4-6 days and it is fertilized once with water.
The third is formula fertilization. Although eggplant absorbs nitrogen, phosphate fertilizer and potash fertilizer are also essential. When topdressing, it is not possible to apply topdressing nitrogen fertilizer every time. In the full fruit period, it is necessary to use phosphate fertilizer and potash fertilizer 2-3 times. Colorant spraying can increase eggplant yield, improve quality, and prolong the effect of picking. Generally, 20 kg of phosphate fertilizer is added every time, and 10 kg of potassium fertilizer (potassium sulfate) is appropriate.
Feed Enzymes preparation is a kind of feed additive which can improve the digestion, utilization, or improvement of animal metabolism to animal feed. As a new type of high efficiency feed additive, enzyme preparation provides an effective way to open up new feed resources, reduce feed production costs, and reduce pollution of livestock and poultry excreta. The compound enzyme preparation is more used in the production of feed industry because of the complexity of feed material structure. A compound enzyme preparation is a product containing 2 or more than 2 single enzymes. Feed enzymes provide guarantee and support for the sustainable development of the feed industry and the breeding industry.

This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
