High-quality strawberry shed cultivation method in southern Shaanxi
The cultivation technology of high-quality strawberry greenhouse facilities refers to the introduction of high-quality, high-yield new varieties of strawberry, the implementation of greenhouses with external and internal membranes, and black plastic film "three membranes" coverage, supporting the Department of drip irrigation facilities, taking balanced fertilization, integrated pest control, scientific management and other comprehensive supporting cultivation technology. Using this technology, New Year's Day strawberries can be listed on the market, and the Spring Festival reaches a period of rich production to cater to the consumption habits and solve the problem that it cannot produce strawberries in the winter of southern Shaanxi. Its cultivation techniques are:
1. Regional selection of fertile soil, pollution-free environment, good lighting conditions, facilities and cultivation levels, convenient irrigation and drainage, transportation will not be handsome and investing capacity of farmers.
2. Variety selection, quality, excellent flavor, early maturing, high-yield Zhang Ji, Fengxiang mainly planted varieties.
3. Seedlings In early April, the mother plants with well-developed root system were selected, old leaves and inflorescences were removed, transplanted in a nursery bed with convenient drainage and irrigation, and deep fertile soil beds. The nursery bed was 1.2 meters wide, and 15 cm deep trenches were opened on both sides for drainage irrigation. The seedlings are transplanted 1 meter apart and the lines are 15-20 centimeters. In general, per mu of greenhouses, 500-600 strains of transplanted seedlings are required. After changing leaves, raise the seedlings with dilute water, and then pour once every 10 days. When the soil surface is white, you can fill the water from the ditch, keep the bed moist, and combine the irrigation, 45% of nitrogen, phosphorus and potassium. Sulfuric acid-type compound fertilizer is poured into water after poured into water. Pay attention to the prevention of anthrax, powdery mildew and gray mold.
4, according to the topography of the building shed, the choice of 6 meters, 8 meters, 10 meters, 12 meters wide cement skeleton greenhouses, depending on the length of the terrain may also be used to build a simple bamboo shed.
5. After the land preparation and ridging are leveled and applied to the ground, the base fertilizer shall be applied, and 2000 kg of cooked farmyard fertilizer per acre shall be disclosed, and 100 kg of cabbage cake shall be disclosed to 45% of yangfeng compound fertilizer and every 50 centimeters of a ridge and 20 meters of ridge height. 30 centimeters, ridge top width 40 centimeters (generally 8 meters wide shed middle 8 ridges, plus two sides each row, 10 meters wide middle 11 ridge plus 1 row on both sides). The base fertilizer can be applied to the ridges to plant strawberry parts. After the ridges are well established, carbendazim and diclafen are used for ridge disinfection.
6. Transplant two rows of strawberries on each ridge, spaced 25-30 centimeters apart, depending on the variety, Fengxiang 14 centimeters, guaranteed 120,000 plants per mu, Zhang Ji 16.7 centimeters, 10,000 plants per mu. After the transplanting, two rows of strawberry seedlings were discharged into the drip irrigation tube.
7. Cover the black mulch in the mid-October to cover the black mulch before frost, use a 65 cm wide black mulch to cover the ridges from both sides, or use a 1.3 metre wide black mulch to cover from the middle, cover the base of the strawberry with soil pressure real.
8. Sheds will be put on shelves in November when the temperature is lower than 10°C. In late December and early January, when the shed is lower than 5°C, it should be applied to the endometrium.
9. In the early stage of management, the main work is to pick the old leaves, prevent pests from diseases and diseases, and control the temperature, pest control, and bee pollination in the later period.
10, after the batch harvested after careful management.
