Apply enough base fertilizer to apply 6,000 kg of organic fertilizer per acre. If it is an old shed, reduce the application amount and add 20-30 kg of potassium sulfate. Organic fertilizer and potash fertilizer should be fully applied and then turned into soil. Special attention should be paid to the fact that the organic fertilizer must be fully decomposed and it is best to treat it with a specialized starter. The application of phosphate fertilizer at the seedling stage in the strong seedling stage can provide early results. 9 square meters of seedbed can be applied to sieve organic fertilizer 200 kg, superphosphate and potassium sulfate 0.5 kg each; when the eggplant seedlings grow to 4 to 5 true leaves, if the lower leaf color is light, can be foliar spray 0.1%~0.2% of potassium dihydrogen phosphate or urea can guarantee strong seedlings. The fruit-promoting fertilizer, when the "gate eggplant" reached the "eye-opening period", the fruits began to grow rapidly, and the whole plant entered the period when fruit growth was dominant. The stems and leaves also begin to thrive and require more fertilizer. At this time, the first topdressing is called detoxification, which is the key period of fertilizer application. Promote the amount of fruit fertilizer, apply ammonium sulfate 30 to 40 kg per acre, or urea 15 to 20 kg, hole application or ditch application, cover soil after application, watering. When the big fertilizer is enlarged for the fruit of the eggplant and the “four-door bucket†begins to develop, it is the peak period for the eggplant to be fattened. At this time, the second top dressing is performed, ie, the large-sized fertilizer. With quick-acting nitrogen fertilizers as the main component and phosphorus and potash fertilizers, it is also necessary to pay attention to the application of medium-sized and trace element fertilizers such as calcium, boron and zinc on the foliage. In combination with watering, 1,000 kg of diluted dilute urine or 20-30 kg of diammonium phosphate is applied per acre. From 10 days after the second fertilizer application to the last time of harvesting, when each layer of fruit begins to swell, it is chased once every 10 days or so, and a total of 5 to 6 times of fat are recovered. Fertilizer and dilute urine are best used interchangeably. Fertilizer spraying from the beginning of the results, according to the growth of spraying 0.2% ~ 0.3% of urea, 0.2% ~ 0.3% potassium dihydrogen phosphate, 0.1% ~ 0.2% magnesium sulfate and other fertilizers. Generally 7 to 10 days once, even spray 2 or 3 times. Biological Bacterial Fertilizer Biofertilizer not only contains a large amount of nitrogen-fixing, phosphate-solubilizing and potassium-releasing active bacteria, but also contains organic matter, humic acid and trace elements. In combination with other fertilizers, it will not only save the amount of fertilizer used, but also solve soil compaction and increase soil microbial content.
