As the saying goes: "There is no income in the harvest, and less income is due to fertilizer." Eggplant in order to yield high first give him to eat well, how to make eggplant eat it in the summer? Here's to listen:
1, right amount.
Eggplant requires the largest amount of nitrogen, but in the hot season, eat less. Urea application per acre should generally be controlled within 30 kg. Because of the high temperature season, the rate of transformation of urea into the soil is relatively fast. After the plants meet their needs, the surplus will be lost. Especially in sandy soils, the proportion of loss will be greater. The amount of ammonium bicarbonate used per acre is not more than 40 kg, which is more appropriate. Excessive application amount will cause loss of nutrients as well as ammonia damage to leaves and fruits of eggplant.
2, law.
It is customary for vegetable farmers to use chemical fertilizers with water, but this method should not be used in summer hot season. Because the temperature is higher, when the chemical fertilizer is flushed, a large amount of ammonia volatilizes will reduce the fertilizer effect. Especially ammonium bicarbonate is more likely to cause eggplant ammonia poisoning. The best effect is to use ditching or hole application, and the thickness of the buried soil after top dressing should be not less than 5 cm to reduce the volatilization of the active ingredients of the fertilizer.
3, a reasonable match.
Although eggplants require the largest amount of nitrogen fertilizer, phosphorus and potassium fertilizers are indispensable, and nitrogen fertilizer cannot be topdressed every time when following the fertilizer. In the full fruit period, it is advisable to top up the application of ternary compound fertilizer twice. The total amount of 2 times per mu should be no less than 40 kg to meet the needs of eggplant growth and results.
