How to do well the basic fertilizer work of eggplant

Eggplant is a vegetable crop which needs a lot of fertilizer and is tolerant to fertilizer because of its long growth time, deep roots and luxuriant leaves. The application of sufficient base fertilizer is the basis for high yield. If plastic film mulching is used in the greenhouse, most of the fertilizer should be applied as base fertilizer because of the inconvenience of topdressing in the later stage. The amount of fertilizer applied in the old shed is different from that in the new shed. Because there is more fertilizer left in the soil of the old shed than that of the new shed, the new shed will fertilize more fertilizer than the old one. In most of the old greenhouse soil, there is excess nitrogen, rich phosphorus fertilizer and insufficient potassium fertilizer. The method that can be taken is: (1) 6000 kg of organic fertilizer is applied every 667m2. If it is the old shed, the application amount can be reduced and 20kg / 30kg of potassium sulfate is applied. Organic fertilizer and potash fertilizer should be fully applied and then turned into the soil. Need to pay special attention to, organic fertilizer must be fully mature, it is best to use a professional starter (such as Gymboree starter) to deal with. It can not only reduce the loss of nutrients, but also completely remove the bacteria, eggs and other exogenous harmful substances in organic fertilizer. (2) combined application of microbial fertilizer, such as 1-2 kg of Gymboree microbial fertilizer per mu, mixed with farm fertilizer, chemical fertilizer or fine soil, can be applied in ditch, hole or spread, it will be better.
