Flowering and budding stage: After planting in November, it should be ploughed by cultivating loose soil and less watering. As long as the soil is not dry, it will not need watering and no fertilizer, preventing the greenhouse temperature from being too high and watering too much and being long.
The winter period: from mid-December to early February, the lowest temperature during this period, the plants grow slowly, and can be top-dressed without watering.
Early spring harvest: Outside temperatures gradually increase from February to March. Plant growth rate, increase the amount of harvest, should be top dressing 2 times -3 times. For each hectare of soybeans in the sulcus, 750 kg - 1500 kg of cooked bean cake, or 225 kg - 300 kg of compound fertilizer. Combined with top-dressing water, keep the soil dry and wet, usually 7 days to 10 days.
Harvesting period: From the end of March to May, the external environmental conditions are appropriate during this period, and the eggplant enters the full fruit period. At this time should be a lot of fertilizer. For every 10 days, 300 kg - 370 kg of compound fertilizer is applied per hectare. When conditions permit, combined spraying can be top-dressed with 0.2%-0.3% of potassium dihydrogen phosphate or urea solution, or 5% of the leaching of the plant ash, or 0.3% of the titanium fertilizer, etc., usually 10 times a day. Combined with fertilizer, timely watering, generally 5 days -7 days a water.
Late harvest: From June to July, the weather was hot and the market price dropped, resulting in a decrease in harvest volume. If you pull out in July, you can skip top dressing. For example, if the person pulls out after the frost in late October, he should still chase the fertilizer once every 10 days, mainly with nitrogen fertilizer, combined with water and irrigation.
The peak season of autumn harvest: From August to mid-October, the outside climate is suitable, and the second harvest peak of eggplant occurs again. In early August, cultivating and weeding should be carried out, and on both sides of the earthworms, we should chase cake-fat fertilizer on both sides, applying 1500 kilograms per hectare, and then applying urea twice, each at 300 kilograms. Watering in conjunction with timely fertilization, keep the soil dry and wet, generally 5 days - 7 days a water.
