Basal fat eggplant fertilizer and fertilizer, must be re-base fertilizer. Before spreading the ground, spread 5000-7000 kg of organic fertilizer per acre, apply 15 kg of superphosphate and 10 kg of potassium sulfate, and then plow till the soil is used for soil preparation; 3000-5000 kg of organic fertilizer may be applied per acre before turning to the ground. Fertilizer, and then do hoeing or hoeing, transplanting and then application or ditch 1500 kg of organic fertilizer and 25-50 kg of nitrogen, phosphorus, potassium compound fertilizer. Can also be combined with the application of trace elements zinc sulfate 1 kg and manganese sulfate 2 kg. During the lifetime of eggplant, it takes a long time to grow fertilizer. Eggplant absorption nutrients rapidly increase after full flowering, so the key period for topdressing is harvesting from the door to the four-door bucket. During this period of time, it can be topdressed every 10 days, each time after the application of ammonium sulfate 15-20 kg ammonium or urea 7.5-10 kg, or ammonium nitrate 10-15 kg, of course, it is best to follow the maturity of human feces. 500-600 kilos of urine. The fertilization method can be applied by ditching, acupuncture or flushing with water. It should be noted that it is best not to chase phosphate fertilizer in the late growth period of eggplant so as not to promote the development of seed in the fruit, and harden the seed coat to reduce the commercial value of the eggplant fruit. During the fertilization process, it is necessary to grasp the principle of applying organic manure and supplemented by chemical fertilizers. The amount of chemical fertilizers should not be too large, especially nitrogen fertilizers, so as to avoid large accumulation of nutrients in the flower buds, causing malformation of carpels during cell division. It even leads to the accumulation of nitrate in eggplant tissue.

Eggplant fertilization how to do
Fertilization at Seedling Stage In order to grow seedlings with thick stems, short internodes, and well-developed root systems, bed soil must be fertile. In a bed of 11.3 square meters, 200 kg of organic fertilizer is applied, 0.5 kg of superphosphate and 0.5 kg of potassium sulfate, and the bed soil is mixed with the fertilizer. Can also apply manure mixed fertilizer 100-150 kg and 1 kg of NPK fertilizer.
