Greenhouse eggplant is a fertilizer-loving crop, with a long growth period and a long fruiting period, high yield, and large amount of fertilizer. Therefore, it is necessary to apply foot fertilizer before planting. The amount of fertilizer applied in the old and new sheds should be different. Because the old shed has more fertilizer in the soil than the new shed, the new shed needs more fertilizer than the old one. It has been determined that most of the old shed soil has excess nitrogen, rich phosphate fertilizer, and insufficient potassium fertilizer. Under normal circumstances, 6,000 kg of organic fertilizer is applied per mu in the new shed, while the old shed can reduce the application amount and add 20-30 kg of potassium sulfate. Organic fertilizer must be fully decomposed. Organic fertilizer and potash fertilizer should be turned into the soil after application, pay attention to the manure and soil should be fully mixed to prepare for planting. Fertilization is generally not required after planting to the flowering and fruit setting period, and the cultivation management is mainly temperature management. The eggplant seedlings in the flowering and fruiting stage are thicker, with short internodes, larger leaves, large buds, shiny leaves, and developed roots. If the stems of the eggplant seedlings are thin, the leaves are small, the color is light, and the flowers are small, it indicates that the seedlings are weak. , Is often caused by lack of fertilizer. At this time, 0.2% urea or potassium dihydrogen phosphate can be sprayed on the foliage. After sitting Mengan, apply 20 kg of ammonium sulfate per acre, ditch or acupoint application. After the Mengans are harvested, 15 kg of urea or 1000 kg of dilute manure water can be applied with water. The eggplant has entered the harvest period, indicating that it has entered a period of vigorous fruit. During this period, water should be watered every 7 to 8 days, and fertilizer should be applied every other time. Organic fertilizer and chemical fertilizer should be used alternately. The application rate is 15-20 kg of ammonium sulfate or 1000 kg of large manure. After harvesting eggplants, add 10 kg of potassium sulfate to supplement the lack of potassium in the soil. 3mm Pediatric Laparoscopic Forceps 3mm Pediatric Laparoscopic Forceps,Pediatric Laparoscopic Forceps,Pediatrics Curved Scissors,Laparoscopic Straight Scissors Tonglu WANHE Medical Instrument Co., Ltd , https://www.tlvanhurhealth.com
