With the adjustment of agricultural planting structure, Xinzhuang Village of Xinji City has fully developed the vegetable cultivation tradition. In the production practice of growing vegetables in greenhouses, it has explored and summed up the early spring tomato, cauliflower, and overwintering spinach planting pattern for one year and three months. 667m2 tomatoes 5000kg, cauliflower 2500kg, winter spinach 3500kg, total output value of 9800 yuan. After deducting depreciation, the investment totals 2,000 yuan, and the annual net benefit is 7,800 yuan. First, planting patterns and access time. Early spring tomatoes are planted in the greenhouse in early January, and planted in greenhouses in mid-March and pulled in mid-July. Cauliflower was raised in mid-June, planted in mid-July, harvested in mid-September, and plucked at the end of September. Overwintering spinach is sown in late September and early October, and harvested on the New Year's Day before and after the new year's harvest. It has been available until the beginning of March. Second, cultivation technology 1, early spring tomatoes. The varieties used were "L402" and "1856", which were raised in the greenhouse at the beginning of January and 30 g of seeds were used for 667m2. Cultivation 667m2 ground nursery bed 3m2. When the seedlings grow two true leaves, the seedlings are planted at a spacing of 10 cm. Before the planting, 667m2 of decomposed organic fertilizer 5000kg, superphosphate 100kg, ammonium bicarbonate 50kg, potassium sulfate 15kg, fine soil preparation. Seedling height 15-20cm, 7-9 true leaves, when the big buds began to plant. 3-5 days before planting, the seedbed is poured once. North and south to the greenhouse, east-west and other row spacing planting, row spacing 50cm, plant spacing 30cm, 667m2 seedlings 4000-4500 strains, after planting water, mulching film cultivation. After planting, the seedlings were planted with water, and within 5-7 days, the shed was maintained at 22-30°C during the day and 13°C at night. The first ear blossomed gradually when it bloomed, kept it below 30°C during the day, and paid attention to the humidity in the greenhouse. When the first spike is blossomed, use a tomato seed or a 2,4-D flower stalk. Use single dry pruning and fight in time. Three to three fruit per ear, leaving 3-4 spikes per plant. When the size of the first panicle walnut is watered, the top-dressing fruit fertilizer is topped, and then one water is poured every 7-10 days, and the top-dressing fertilizer is applied every other water, and each 667m2 chases the urea 10-15kg. Timely prevention of pests and diseases. Harvesting began in mid-and late May and was pulled in mid-July. 2, cauliflower. The variety was selected "Fenghua 60", which was exposed in the open ground in mid-June, and used 50g for 667m2. Immediately after sowing, put shade sheds on seedlings to reduce the temperature and prevent rain. Seedlings were planted at 5-6 leaves, with row and plant spacings of 40 cm and 667 m2 with 4,000 seedlings. Before planting, 667m2 of organic fertilizer 5000kg, superphosphate 150kg, ammonium phosphate 50kg. Casting planting water, Huanmiao water, cultivator planing seedlings. When the flower ball is about 3cm, it is top-dressed with water, and 667m2 is followed by 20kg of urea. Afterwards, a small amount of water is poured every 5-7d to keep the soil moist and pay attention to the drainage after rainfall. In order to prevent the sun from sticking to the ball, the outer leaf can be folded on the flower ball to improve the quality and timely control of pests and diseases. Harvesting began in mid-September. 3, winter spinach. Variety selection round leaf spinach spinach hybrid No. 10. In late September (before and after the autumnal equinox), the land was prepared and live. 667m2 organic manure 5000kg, the organic fertilizer and the bauxite turning and mixing evenly, flat surface to be broadcast. Usually 5m2 sowing pure seeds 50g. Dry seed sowing method is used to spread the seed evenly on a flat surface, and then use a tweezers to rake it from head to layer along the surface. The depth is 1-1.5cm, so that the seed will enter the clay and then step on it again. After stepping on water. Seedlings can be produced 4-5 days after sowing. After the seedlings before the seedlings, it is necessary to ensure that the surface is moist. Before the next frost (usually in mid-October), the film is sealed. At this time, the temperature during the day is high. During the day and at night, the feet of the shed film must be uncovered. After the greenhouse is lowered, it is opened during the day and buckled at night. When the temperature decreases again, the feet should be sealed during the day. If you encounter high temperatures in the future, you can open the greenhouse door to put a little wind, the temperature is controlled at 15-20 °C. Water should be poured one time in the first 2-3 days before the shed film, and water may not be applied until the shed is shed. Timely prevention of pests and diseases. When the plant height 25cm can be harvested, has been supplied to around the Spring Festival.
