First, preparation before planting
1. After clearing the land before harvesting, the 30-inch insect net should be installed on the door and the vents on both sides of the greenhouse, and the shade net should be prepared.
2. Work on the ground. Before planting, according to the south-south direction of the greenhouse (shun shed), the ditch will be used as a shovel for the 667-square-meter ditch, and the fully-fertilized organic fertilizer will be 3 to 6 square meters and the ternary compound fertilizer 30-50 kg, mixed into the ditch soil, and sprayed and killed. Insecticides (can be used with phoxim 30 ml per 667 square meters, 50% carbendazim wettable powder 0.1 kg with water 15 kg, evenly sprayed inside the ditch), blended with flattened, sealed soil ditch, for sorghum. The autumn greenhouse shed melon in Beijing is generally cultivated by double-row vines. The distance between the two rafts is 1.4-1.5 m, the width of the glutinous rice is 0.7-0.8 m, and the height of the glutinous rice is 20 cm. The mulch covers the mulch.
Second, melon planting
1. Planting density. In order to control the disease, the cultivation density of melons in autumn greenhouses is generally smaller than that in spring. The number of plants per 667 square meters of single vine pruning and hanging vine cultivation is generally about 2,000 melons and about 1,800 melons.
2. Colonization time and method. After sowing, the seedling age is about 15 days in time. At the time of planting, the bottom should be sufficient. Before planting, the wells should be dug on the wells. The depth of the hole is slightly deeper than that of the nutrient. The spacing between the two rows of vines is 1.4 to 1.5 meters. Each row is planted in two rows, and the "triangle" is staggered and planted at a distance of about 40 cm. The planting time is selected after 3 pm in the afternoon or on the cloudy day, and the plants are planted according to the size of the seedlings. Watering in time on the day of planting.
