Eggplant is a fertile crop. Soil conditions and fertilization levels have a great influence on eggplant's fruit setting rate. When the nutritional conditions are good, less flowering, malnutrition will increase the short stud flower, flower growth is poor, the fruit setting rate is not high. The nutrient requirements of eggplant during different growth periods are different. Fertilizers in the initial growth period are mainly to promote the vegetative growth of the plants. With the development of the growth period, the nutrient transfer to the flowers and fruits increases; at the flowering stage, the absorption of nitrogen and potassium is significant. Increased, if nitrogen is insufficient during this period, flower development is poor, short studs increase, and yield decreases. Due to the low soil temperature in winter, the absorptive capacity of eggplant for fertilizers is reduced, which is slightly different from other seasons. First, base fertilizer 6000 to 7500 kilograms of decomposed organic fertilizer per acre, plus 25 to 35 kg of superphosphate, 15 to 20 kg of potassium sulfate, 2 kg of zinc sulfate, 80 kg of calcium silicate fertilizer, and 10 to 20 kg of magnesium sulfate or magnesium nitrate Spread evenly on the surface of the soil, and evenly plunge into the plough layer of soil in combination with the ground. Second, nursery fertilizer Eggplant seedlings require higher quality of nutrient soils. Only those with high quality nutrients can grow strong seedlings with short internodes, thick stems and well-developed roots. Normally, every 1 square meter of seedbed is applied with 20 kg of decomposed organic fertilizer, 0.3 kg of superphosphate, and 0.1 kg of potassium sulfate. The seedbed soil is mixed with organic fertilizer and chemical fertilizer. If you encounter low temperature or soil fertility, you can spray 0.3% to 0.5% of urea solution. Third, top dressing When the "door eggplant" reached the "window-opening period", the fruit began to grow rapidly and the first top dressing was carried out at this time. Mushi urea 9 ~ 11 kg or ammonium sulfate 20 ~ 25 kg, when the "sauce" fruit enlargement when the second topdressing, when the "tomato" to begin development, is the peak period of eggplant fertilizer, should be the third The top dressing. The same amount of topdressing for the first three times, the amount of topdressing can be halved afterwards. When the ground temperature is low in winter, the top-dressing compound fertilizer should be mixed with a certain amount of high-quality humic acid, or a sufficient amount of high-quality water-soluble fertilizer containing N, P and K should be used instead of compound fertilizer to reduce the damage to the root system caused by single compound fertilizer.
