1. Soil selection Soil sandy soils that have not been planted with melon crops, have good drainage, are rich in organic matter, and retain good water and fertility have been selected for more than two years. The soil pH value is preferably 6-7.5. 2. Sowing Date Arrangement The first cucumber was planted in the greenhouse in mid-March, and transplanted to Daejeon in early April. Harvested in mid-to-late June. The second cucumber is planted in late May, transplanted in mid-June, and harvested in early July and August. The planting should not be too late. The third crop was raised in the middle of July and transplanted in early August and harvested in the early September and early October. All the three oysters use seedlings for nutrition and watering, pouring enough water before sowing, sowing 1-2 seeds per pod and covering 1 cm thick soil. After the second three days of broadcasting, the brackets were inserted to cover the shade nets, and high temperature and heavy rain affected the whole seedlings, and the seedlings were set in time after emergence. 3. Variety selection Choose resistant and adaptable cucumber varieties. Use 80-100 grams per acre. 4. Soil fertigation Apply 2500 kg of organic fertilizer per acre, 100 kg of cooked cake fertilizer, 50 kg of Huimanfeng granular fertilizer, and 2-3 kg of carbofuran. Mix the soil fertilizer and medicine with a rotary tiller. The field is double row high ridge every 100-120 centimeters, two ridges in the middle ditch, irrigation and drainage dual purpose. Ditch well around the field, open the outlet, and then cover the black mulch on the ridge (with protection against rain, moisture and weeding). 5. Timely transplanting seedlings are mastered in about 25 days, there are 3-4 leaves when transplanting, acres planted 4000-5000 strains. The second cucumber was planted on the front of the cucumber root, and the third cucumber was placed on the second cucumber root. Seedlings were sprayed once at each of the 3-leaf and 6-leaf stages, and the concentration was 150-200 mg/kg ethephon solution to increase the number of female flowers and increase the yield. 6. Fertilizer and Water Management Based on the application of basal fertilizer, each cucumber should be topdressed twice. After the first transplant, 500 kilos of manure will be added to water per acre, and small fertilizers will be applied to promote the growth of live trees. After the second dressing in the root melon, 30 kg of Huimanfeng granule fertilizer was used per mu. In the later period, combined sprays were used for extra-root dressing. In summer and autumn, the temperature is high, the light is strong, and the soil is prone to drought. It should be watered in time to resist drought. Watering should be done in the evening. Watering at noon should be avoided. 7. Grab the whole twigs and cucumbers immediately after transplanting. The side vines that grow in the main vines from 1 to 7th section should be removed as soon as possible. After the main vine spreads over its shelves, it picks up the heart and lets it grow naturally later. After the third cucumber is planted, the cucurbit frame is replaced or fixed at any time. 8. Pest control boxes, mildew, powdery mildew, etc. with mothionine, chlorothalonil prevention and control; locusts, melon worms, etc. with cicado, Wanling prevention. Spray once every 7-10 days. 9. Harvest in time Usually 2-3 days harvest 1 time, full fruit harvested once a day.
