Pumpkin is one of the vegetables that everyone likes. The young shoots, tender stems, tender leaves and young petiole of pumpkin seedlings, as well as tender stems and flower buds can be eaten. Pumpkin seedlings do not need to fight drugs and kill insects, it is really pollution-free food. So how do pumpkin seedlings grow?

How to cultivate pumpkin seedlings is as follows:

The technical points of pumpkin seedlings are as follows: Select the variety. Choose the local seedlings, melons and long, and the large-sized pumpkins are good varieties, such as pillow melon, plate melon, beef leg melon, Dahongpao melon, yellow petal melon and so on. It is not advisable to use short varieties of melon seedlings.

Soaking seeds and germination. The pumpkin seeds are exposed to the sun for 2 days, and then placed in 50 ° C hot water and stirred immediately. When the water temperature drops to about 30 ° C, the seeds are soaked for 15-20 minutes, then naturally cooled, and the seeds are soaked for 7-12 hours. After immersion, the germination temperature is maintained at about 30 °C, and it can germinate in two days.

Fine land preparation. Choose the seedlings with good drainage, the bottom of the groundwater, and the soil fertile rice fields and vegetable fields. According to the width of 1.5 meters, open the trench, the width of the trench is 30 cm, the depth of the trench is 15-20 cm, and the drainage ditch is opened on all four sides.

Sowing at the right time. In order to early and extend the time to market, seeding can usually begin in February and can be planted in batches until August. The seedlings were planted at a row spacing of 20 cm, and the plants were planted at a distance of 10 cm. Two seeds per stalk were planted, and water was sown after sowing, covering a 2 cm thick nutrient soil.

Timely fertilization. Apply enough base fertilizer. Each mu is put into the rotten bovine pig manure 2000--2500 kg or the soil miscellaneous fertilizer 2500--3000 kg, and the phosphate fertilizer 20 kg. After sowing, it is drenched with decomposed manure or biogas slurry. The ash or nutrient soil that has been fully fermented and fermented will be prepared in advance, and then the mulch film will be laid on the surface of the glutinous rice, and the soil will be compacted with soil. After emergence, let the seedlings grow under the membrane. Topdressing generally uses decomposed manure and manure, and must be chased to ensure sufficient supply of manure to promote the rapid growth of melon seedlings. After each harvest, the quick-acting nitrogen fertilizer should be applied to the melons in time to promote the early development of axillary buds.

Timely harvest. When the melon seedling grows to a height of 40 cm and has 5-6 pieces of true leaves, it can be harvested in batches, and 1 to 2 true leaves are left at the base to cut the upper tender seedlings. The axillary bud grows to 40 cm and can be harvested, so many times. Spraying 80 mg/kg "920" solution 5-7 days before each harvest can increase the yield by more than 30%, and reduce the formation of thick fiber at the base section. The seedlings are very tender and soft and the quality is improved. .
