How to fertilize eggplant

Fertilization at seedling stage In order to cultivate seedlings with thick stems, short internodes and developed roots, the bed soil must be fertile. 200 kg of decomposed organic fertilizer, 0.5 kg of calcium superphosphate and 0.5 kg of potassium sulfate are applied to 11.3 square meters of bed soil, and the bed soil and fertilizer are mixed evenly. 100-150 kg of mixed manure and 1 kg of NPK compound fertilizer can also be applied. Eggplant base fertilizer like fertilizer and fertilizer tolerance, must be heavy base fertilizer. Before ploughing, 5000- 7000kg organic fertilizer is applied per mu, 15kg calcium superphosphate and 10kg potassium sulfate are applied in combination, and then ploughing and soil preparation are carried out; 3000- 5000kg organic fertilizer can also be applied per mu before ploughing, and then ridge or furrow is made; 1500kg organic fertilizer and 25- 50kg nitrogen, phosphorus and potassium compound fertilizer are applied in holes or furrows during transplanting. It can also be combined with the application of trace elements zinc sulfate 1 kg and manganese sulfate 2 kg. Eggplant topdressing life, fruit period is very long need to topdressing many times. The nutrient absorption of eggplant increases rapidly after full bloom, so the key period of topdressing is from the door to the four door harvest. During this period of time, topdressing can be applied once every 10 days, and 15-20 kg of ammonium sulfate or 7.5-10 kg of urea or 10-15 kg of ammonium nitrate can be applied to each mu. Of course, it is best to apply 500-600 kg of decomposed human excrement. Fertilization methods can be furrow application, hole application or irrigation with water application. It should be noted that it is best not to chase phosphorus fertilizer in the late growth stage of eggplant, so as not to promote the seed development in the fruit, the seed coat hardening and reduce the commodity value of eggplant fruit. In the process of fertilization, we must grasp the principle of fertilization based on organic fertilizer and supplemented by chemical fertilizer. The amount of chemical fertilizer should not be too large, especially nitrogen fertilizer, so as to avoid a large accumulation of nutrients in flower buds, resulting in the formation of abnormal carpels in the process of cell division, and even lead to the accumulation of nitrate in eggplant tissues.
