Pre-planting pumpkins can receive seedlings and can be harvested later. Pumpkin seedlings, as a new special dish, has become one of the major vegetable varieties in urban and rural vegetable markets in recent years. The young shoots, tender stem sections, tender leaves and tender petioles of the pumpkin seedlings, and the tender stems and flower buds can be eaten. Pumpkin seedlings do not need to fight pesticides, really pollution-free food. The technical points of pumpkin seedlings are as follows: Select varieties. Local seedlings, melons and long shoots were used as seedlings, and pumpkins were used as good seeds, such as pillows, melons, melons, dahongpa melons, and yellow melons. It is not suitable to use short varieties of melon.
Soak germination. The pumpkin seeds were sun-dried for 2 days and placed in hot water of 50°C to immediately stir away the fire. When the water temperature dropped to about 30°C, the seeds were soaked for 15--20 minutes and then naturally soaked for 7-12 hours. After soaking, the germination is maintained at a germination temperature of about 30°C, and germination occurs within two days.
Fine site preparation. Choose pumpkin seedlings with good drainage, rice fields and vegetable lands where groundwater level is at the bottom and soil is fertile. Width 1.5 meters wide, open a good ditch, groove width 30 cm, ditch depth 15--20 cm, four sides open drainage ditch.
Timely sowing. In order to advance and extend the time to market, planting can generally begin in February, and it can be sowed in batches until August. The seedlings were planted at a spacing of 20 cm and planted at a distance of 10 cm. Two seeds per pod were sown and then sown and covered with 2 cm thick nutrient soil.
Timely fertilization. Apply base fertilizer. Per mu of put into the decomposed cattle pig manure 2000--2500 kg or soil miscellaneous fertilizer 2500--3000 kg, 20 kg of phosphate fertilizer. After sowing, they were thoroughly immersed in decomposed manure or biogas slurry. Will be prepared in advance after a full fermentation of fermented ash or nutritious soil cover species, and then mulching film on the surface, surrounded by soil compaction insulation. After emergence, let the seedlings grow under the membrane. Composting generally uses decomposed manure, livestock and manure, and must be chased to ensure sufficient supply of manure to promote the rapid growth of melon seedlings. After each harvest, timely reapplication of available nitrogen fertilizer to the quail, promote early onset of buds.
Harvested in time. When the melon seedlings grow to 40 cm in height and there are 5--6 true leaves, they can be harvested in batches, leaving 1-2 true leaves at the base to cut off the upper tender seedlings. The axillary buds grow to 40 cm and can be harvested, so repeatedly. Spraying 80 mg/kg of the "920" solution 5-7 days before each harvest can increase yields by more than 30%, and can reduce the formation of coarse fiber in the base section. The melon seedlings appear to be very tender and soft, and their quality is improved. .
