Spring greenhouse cucumber cultivation management technology can extend supply
With the popularization and scale of facilities and vegetables, their production technology has gradually upgraded. Through planting seedlings, multi-layer cover, hanging cultivation, vine cultivation, water and fertilizer integration and other new technologies to improve planting levels and cucumber yield, thereby increasing the planting efficiency of vegetable farmers. Planting in early December will be planted in mid-January in the following year, and will be listed in the first half of March until the first day of July. The cultivation techniques of spring cucumber cultivation in greenhouses are now shared as follows: 1, variety selection Buy premature, high-yield, high-quality, disease-resistant all-female varieties of commercial seedlings or grafted seedlings such as Jinemen 98, Shenqing No. 1, Del 79 and other fine varieties. 2, soil preparation and fertilization Combined with the preparation of the soil, 200-250kg of bio-organic fertilizer and 100kg of ternary compound fertilizer per 667m2. According to the 1.6m bag ditch, the 8m wide shed opens 5 cars, the ditch width 40cm as the deep ditch sorghum, and the mulch film and drip irrigation belt are to be planted. 3, colonization 2 weeks before planting, cover the outer membrane of the shed (8 filaments thick, 1 silk = 0.01mm) and close the greenhouse to increase the temperature. In the middle of January, choose the sunny planting, planting 2 rows per plant, plant spacing 40cm, row spacing 50cm, planting 2200～2300 per 667m2. Strain. Root water is poured in time after planting. 4, plus layer coverage When the minimum temperature drops to 0 °C, 2 layers of cover film and 1 layer of skirt film are added to the shed to increase the temperature. The first layer cover film: at the height of the roof (3.2m high), about 2.7m from the ground, pull a thick wire with a diameter of 5mm along the front and rear doors of the shed, and then pull the roots along the left and right sides of the shed along the wire. A fine wire of 3 mm in diameter, a pitch between the fine wires of 3 m and then a flat film (4 wire thick). The second layer cover film: about 2.4m from the ground directly below the roof, pull a thick wire with a diameter of 5mm along the front and rear doors of the shed, and then pull a few 3mm thin wire with a diameter of 3mm along the left and right sides of the shed. The spacing between the fine wires is 3m, then the film is spread (5 wires thick), and the second film is pulled or closed at any time depending on the temperature rise and fall of the shed. Skirt: A wire with a diameter of 5 mm was pulled from the ground at a height of 0.8 to 1.0 m from the ground, and the film (5 wire thickness) was placed directly on the wire. 5, hanging vine Before the vines, the wire with a diameter of 5 mm was horizontally drawn in the direction of the cultivation line at a height of 2.0 to 2.2 m above the ground of each row of plants. The two ends of the wire were fixed on the scaffolding of the front and rear doors of the steel shed. In the middle section of the wire, a thin wire with a diameter of 3 mm is pulled longitudinally every 3 m. One end of the longitudinal wire is fixed on the transverse wire and the other end is fixed on the steel frame of the roof, so that the horizontal wire can be straightened to avoid falling. After the vine is started, one end of the plastic rope is tied to the transverse wire, and the other end is wound on the sling in a clockwise direction at the base of the stem of the plant. 6, falling vine Before the vines are selected, the old leaves, diseased leaves and diseased melons of the lower part of the plant are removed on a sunny day. Each plant retains more than 15 functional leaves to meet the growth needs of the squash. After picking the leaves, in order to avoid the infection of the wounds, fungi and bacterial fungicides should be sprayed in time. When the vines are sown, first loosen the lower end of the sling to move the stalks to the ground, and gradually entangle the stalks along the stalks, and then fasten the lower ends of the slings. In the future, depending on the growth of the plant, it will fall once every other time. 7. Water and fertilizer management After the live seedlings, the first seedling fertilizer is applied with 14kg of Russian potassium source fertilizer per drip irrigation per 667m2; the second top dressing of the melon is 667m2 per 667m2, Dr. Shinong organic fertilizer 25kg+U potassium nitrate (imported by Russia) 25kg; The third time in the melon season, every 667m2 rushed Dr. Shinong organic fertilizer 30kg + U potassium nitrate 30kg. 8. Pest control The main pests and diseases of spring cucumber are downy mildew, bacterial angular leaf spot, epidemic disease, root rot, and whitefly. Downy mildew, before the onset of the disease, 10% cyanosin suspension can be sprayed with 2000 times liquid. In the early stage of the disease, 53% refined nail cream, manganese zinc wettable powder 500 times liquid or 72.2% creamy saline hydrochloric acid 800 times liquid can be used. Spray control. Bacterial keratosis can be controlled by spraying with 72% neomycin WP or 72% agricultural streptomycin soluble powder 3000-4000 times, once every 7 days for 2 to 3 times. The root rot can be treated with 99% of the original carbendazim medicinal solution 3000 times or 70% thiophanate-methyl WP 700 times. Bemisia tabaci can be controlled by spraying with 2.5% bifenthrin emulsifiable concentrate 800 times. The output of 667m2 is about 7500kg, and the output value of 667m2 is more than 20,000 yuan. It can raise the morning market, extend supply, increase production, and increase the planting efficiency of vegetable farmers.
