Pumpkin planting Technology and Management: how to grow Pumpkin? How to plant pumpkins and produce many melons

Do you know how to grow pumpkins? Do you want to know about it? Pumpkin is suitable for growing in cool climate of 15-25 ℃, but grows slowly when it is below 8 ℃. The plant was frozen at 0 ℃, and it was easy to suffer from virus disease in high temperature and dry season. We should pay attention to this when planting. How to plant pumpkins, how to plant more fruit.

Cultivation techniques

First, cultivate strong seedlings: the seeds were soaked in 50 ℃ warm water for 3 hours and then germinated, and the temperature was kept at 25-30 ℃. The seedlings were sown when the bud was 0.5 cm long, and the seedlings were basically unearthed after 5 days. The seedlings were planted in spring for 15-20 days (2-3 true leaves) and in autumn for 10-12 days.

Second, fine soil preparation: it is appropriate to choose loose and fertile sandy soil or paddy fields. Generally from the high border planting, border width of 6 meters, planting on both sides, or border width of 3 meters, unilateral planting, plant spacing of 0.4 meters, about 400 plants per mu. 1000 kg of mature organic fertilizer, 20 kg of compound fertilizer and 15 kg of phosphate rock powder were mixed with the soil per mu to wet the soil.

Turtle back-shaped border surface, covered with silver-black plastic film in the planting area, black surface to the ground, can block the sun, eliminate weeds, silver gray face up, play a reflective role, can ward off aphids and control virus. Plastic film can not only keep fat and heat preservation, but also benefit fruit coloring, beautiful appearance and increase yield.

Third, strengthen management: after covering the plastic film, cut a triangular planting hole with a side length of 10 cm every 40 cm in the plastic film area. after planting, drench the root water, and cover the plastic film around the plant with soil.

Pumpkin is tolerant to fertilizer, so it is appropriate to apply sufficient base fertilizer and re-apply expanded pumpkin fertilizer. After planting, the amount of nitrogen fertilizer should be controlled to avoid overgrowth, late female flowers and serious fruit drop. It is generally divided into three times of topdressing, and the first time is about 10 days after planting, around the hole with 0.5 kg urea and 1 kg compound fertilizer plus light dung water. For the second time, when the vine was 35 cm long, 1.5 kg urea and 2.5 kg compound fertilizer plus light dung water were applied to the vine edge per mu. The third time in the melon expansion period, combined with the whole border surface, 10 kg potassium sulfate fertilizer and 20 kg compound fertilizer were applied to the border surface per mu. At the same time, combined with foliar topdressing, "Yunda-120" was sprayed with potassium dihydrogen phosphate or other foliar fertilizer to improve the fruit setting rate.
