The size of the greenhouse is 6 meters wide, 55 meters long, and the height of the roof is 2.5 meters. A 40 cm wide ditch and walkway is opened in the middle of the shed, and the sides are made 2.8 meters wide. Sakaguchi arranges the first year of April to plant okra, interplanting snow sakura, and the snow sakura harvest in June. From late June to late October, the okra is harvested in batches. In late October, the old stalks of okra are removed, and the ice is transplanted after fertilization. Dish (in mid-September, seedling nursery), harvested in batches from December to early April. In the second year of April, after fertilization, the greenhouse will be converted into paddy field, transplanted in mid-to-late May (the mid-April seedling), and in mid-October, the harvest will end, and the fertilization of the watercress will be applied immediately, from December to the third year of April. Harvest the watercress in batches. Planting income in the first year of harvesting more than 1200 kg of okra tender fruit per mu, the output value of 10,000 yuan; interplanting snow sakura can harvest about 2,000 kg of tender stems and leaves, the output value of 0.8 million to 10,000 yuan; iced can harvest tender stems and leaves 2000 About kilograms, the output value is 30,000 to 40,000 yuan, and the annual output value of land wild vegetables is 50,000 to 55,000 yuan. In the second year, the harvest can be 80-100 kilograms per mu, and the output value is about 8,000 yuan. The harvesting of the tender stems and leaves of western vegetables is 5000-6000 kilograms, the output value is 40,000 to 45,000 yuan, and the annual output value of aquatic vegetables is about 50,000 yuan. Excluding the cost of imported materials, the annual net income per mu can reach more than 40,000 yuan. In the first year of planting technology in the first year of April, 1000 kg of manure per acre of poultry and livestock is applied. After the surface is leveled, the seeds of snow sakura are spread, and the seeds of the okra are pressed (with the foot), and the okra seeds are placed at a distance of 70 cm and the distance between the holes is 50 cm. 3 seeds per hole, and sprinkle enough water after sowing. In late April, the greenhouse was replaced with an insulation film. In June, after the snow sakura was removed from the market, 10 kg of compound fertilizer and 10 kg of urea were applied per acre. The hole was applied between the okra plants, and the okra was fixed at the same time, leaving one plant per hole. In the late July and early September, each fertilizer was applied to the okra field. Ice seedlings are planted with 2 to 3 seeds per seedling (taken with ear spoon), sprinkle water after covering the thin layer of soil, pay attention to shading, ventilation and moisturizing, transplanting 4 to 5 leaves after 30 days of sowing, the row spacing is 30 cm, 10 kg of urea per mu for 10 days after transplanting, sprinkle water after application, and then apply urea once a month. In the end of November, the greenhouse was covered with a layer of membrane insulation. Before the end of December, the second layer of shed film was covered. At the end of February, the endometrium was removed, and in mid-April, the outer membrane was removed. In the second half of April of the second year, after the application of 1000 kg of dried manure per acre of grass, the rice field was changed into a paddy field, and the seedlings were planted. The 50-meter-high field around the field was covered with water, and the shallow water layer was transplanted in the greenhouse in the middle and late May. It is not necessary to cover the membrane and does not need insect nets. The 6-meter-wide shed can be planted in 3 rows of tamping, one per hole, the row spacing is 2 meters, and more than 160 plants per acre. There are very few pests and diseases in the tamping, no need to prevent and cure. During the growth period, the water level is increased with the growth of the seedlings. In September, before the smashing of the line, 15 kg of compound fertilizer and 5 kg of urea were applied per acre. The fertilizer was wrapped in mud balls, and about 50 grams of fertilizer was thrown in each mud ball. After harvesting in October, 1000 kg of dried manure per acre was applied, and the seeds of the watercress were sowed, and the seedlings were planted in 5 days. In the end of November, the greenhouse was covered with a film, and the second layer of membrane was covered before the end of December. The endometrium was removed at the end of February, and the outer membrane was removed in mid-April. After each harvest, the watercress is applied with 15 kg of urea per acre, and a shallow water layer is built after the application. After the harvest of the watercress, the next round of planting will be carried out in the greenhouse. Matters needing attention Water and drought rotation can be planted all the year round, terrestrial vegetables can also choose oil wheat, chicory, dandelion, etc., aquatic vegetables can also be selected with Ci Gu, oysters, water celery and other varieties. The park and farmers should decide the planting area of ​​wild vegetables according to the market dynamics, and the single varieties should not be planted blindly.

Greenhouse, wild vegetables, water and drought, continuous high-efficiency
After 3 to 5 years of continuous cultivation of greenhouse vegetables, the surface soil of the greenhouse is heavily salinized, and the accumulation of pests and diseases for a long time will cause serious reduction in production and a decrease in benefits. In the greenhouse, the author uses the aquatic vegetables such as citrus, western vegetables and okra, snow sakura, iced vegetables and other methods of resistance to pests and diseases, and salt-tolerant land-based wild vegetables, which can effectively avoid soil salinization and reduce the occurrence of pests and diseases. In order to maintain a bumper harvest in the greenhouse. These five vegetable varieties have good nutritional value and health care functions, which are well received by the public and have high planting benefits.
