One cucumber and two cultivars
The cucumber has a short growth period, and it has a large number of flowers and materials used to cover the film during the cultivation process, and the planting efficiency is low. If the planting period is reasonably arranged, using a melon rack to grow cucumbers in summer and autumn in two crops, a good cost-saving effect can be achieved. The method is as follows: I. Sowing Date Arrangement: The first cucumber in Jiangxi is arranged for seedling in late May, transplanted in mid-June, and collected in early July-August. The second crop was raised in mid-July, transplanted in early August and harvested in early September-October. The use of nutrition sports seedlings, pouring enough water before sowing, each seed sowing 1-2 seeds. After sowing, the bracket is inserted to cover the shade net, and high temperature and rainstorms affect the whole seedlings, and the seedlings are set in time after emergence. 2. Fertilization for soil preparation: After harvesting, apply 2500 kg of organic fertilizer per 1/15 hectare, 100 kg of cooked cake, 50 kg of granular fertilizer, 2-3 kg of carbofuran, and turn the soil with a tractor. For every 100-120 cm in the field, double rows of high ridges, two ridges between the middle ridges, irrigation and drainage. The trenches were excavated around the field and the outlets were well opened. The black mulch was covered on the ridges (prevention of rain, protection and weeding). Third, timely transplanting: generally controlled in the seedling age of 25 days, 3-4 leaves when transplanting, 1/15 hectare planted 3500-4000 strains. The second cucumber was planted next to the first cucumber root. The seedlings were sprayed with 150/1000000, 200/1000000 ethephon aqueous solutions at the 3 leaves and 6 leaf stages, increasing the number of female flowers and increasing the yield. IV. Fertilizer and water management: topdressing the base fertilizer on two occasions, the first time after transplanting with 500 kilograms of human waste water “small fat water†point facilities, to promote live tree hair. After the second topdressing, after applying the squash, 30 kg of granular fertilizer was used to deepen the ditch. In the later stage, the combined application of sprays for extra-root topdressing may use plant vigor and plant power 2003. In summer and autumn, the temperature is high, the light is strong, and the soil is drought-prone. It should be watered and drought-proof in time, and watering should be carried out in the evening. Never avoid watering at noon. 5. Pruning: Pruning cucumbers immediately after transplanting. The side vines that grow in the main vines from January to June are removed as early as possible. After the main vine spreads over its shelves, it picks up its hearts and grows naturally afterwards. Six, pest control: downy mildew, powdery mildew, etc. with mothionine, chlorothalonil prevention and control, aphids, melons, etc. with anti-Taibao, Wanling prevention and control, spraying once every 7-10 days. VII. Harvesting in Time: Cucumber harvesting sooner or later and frequency have an impact on the yield and quality. The melons are harvested in time for the development of melons and plant growth. Usually 2-3 days harvest once, full fruit harvested once a day.
