Pumpkin planting: how to fertilize pumpkins?
How to fertilize pumpkins? Please give a detailed description of pumpkin cultivation can refer to the following methods of fertilization: re-application of base fertilizer, timely planting: pumpkin well-developed root system, strong fertilizer absorption capacity, turn 30cm deep before winter, turn two ploughs in the next spring. 75000 kg of rotten high-quality organic fertilizer per hectare should be sprinkled before turning the second plough or concentrated in the sowing border. After ploughing and leveling, make sowing or planting beds, planting about 4500 plants per hectare. After transplanting slow seedlings of pumpkin, if the seedling is weak and the leaves are light and yellow, you can apply fertilizer combined with watering, applying 3750-4500 kg of sparse dung water per hectare. When the plant enters the middle stage of growth and sits on 1 or 2 young melons, fruit-promoting fertilizer should be re-applied before the row is closed, generally 15000 ~ 22500 kg of rotten thin dung water or cake fertilizer water per hectare. During this period, some droughts can be combined with watering, and 225,300 kg / ha of compound fertilizer can be applied with water. After the fruit is harvested, a small amount of organic fertilizer can be applied to prevent the plant from senescence and increase the yield in the later stage. If you do not harvest tender melons, but are prepared to harvest mature melons, you do not have to fertilize them in the later stage, and only pay attention to watering or drainage. In the middle and later stages, 0.2% potassium dihydrogen phosphate can also be sprayed, once every 10 days and 2 times in a row. Pumpkin likes organic fertilizer, so the amount of fertilizer and nutrient combination should be determined according to plant growth and soil fertility. If the growing point of melon vine is strong and warped, it is not suitable to apply fertilizer when the leaf color is dark green, in order to prevent overgrowth and melons; if the leaf color is light green or yellow, it should be fertilized in time.
