In recent years, farmers in our land have used greenhouses to intercropping potatoes, leeks, melons, cabbages, and asparagus. Generally, they produce 1500 kilograms of potatoes, 1,000 kilograms of leek, 5,000 kilograms of melon, 3,000 kilograms of summer cabbage, and 5,000 kilograms of autumn and winter lettuce. .
First, the mouth arrangement
Potatoes were grown in greenhouses in late January, and potato harvesting ended in early May. Live leeks in early February can be harvested for 2-3 茬. The leek was transplanted and transplanted with wax gourd seedlings, which was listed at the end of June to the beginning of July. In early July, summer and autumn cabbages were broadcast live, and in mid-September Chinese cabbage was listed. Planting autumn and winter lettuce at the end of September and harvesting before the end of December.
Second, cultivation technology
1. Potato. Inside the greenhouse, two meters wide and two ridges were planted to plant potatoes. During the planting period, drugs are used to prevent and control underground pests, and after planting, they cover the plastic film and strengthen management after emergence.
2, leeks. Use a variety of red round leaf leeks in Changzhou. After fine soil preparation, sowing, planting manure manure after sowing, and cover the film to facilitate rapid emergence. Many light nitrogen fertilizers were applied after emergence to make the stems and leaves grow young.
3, melon. Choose sun-burning, transport-resistant, dense-skinned gourd melon varieties. Before transplanting, 2000 kg of livestock manure and 50 kg of ternary fertilizer were applied per acre. 500-600 plants per acre. Immediately after planting a living plant, a rare human fecal urine fertilizer was applied. When the wax gourd grows to 50 cm long, the whole vine and young fruit should be reserved. Only 1-2 side vines are left before the fruit is set and the rest are removed. After the fruit is set, the lateral vines grow naturally and the main vines retain 15-20 leaves after the fruit is set.
4, summer cabbage. Use early-maturing, high-yield, heat-resistant and disease-resistant varieties such as Xiayang 50. Each mus applied 2,000 kg of organic fertilizer and 50 kg of compound fertilizer. Soil preparation for planting, planting a width of 70 cm, planting at a spacing of 3550 cm, planting about 4,000 plants per acre. Appropriate time seedlings, Dingmiao, make up seedlings. 30 days after sowing, topdressing 20 kg of urea per acre.
5, autumn lettuce. Select high-yield, cold-resistant, disease-resistant varieties such as species are. In early September, shade nets were used to cover seedlings. At the end of September, soil preparation was conducted. The lotus root was 1.2 meters wide. Planting lettuce seedlings was planted at a spacing of 35 cm and 40 cm. About 6000 plants were planted per acre. After transplanting the plants, they will loosen the soil immediately after they are alive. In early November, the greenhouse film will be covered and the temperature of the greenhouse will be kept above 15°C.
