(a) Select improved varieties. Choose early and high-quality varieties such as local cucumbers and mountain cucumbers.
(2) Applying base fertilizer to the site preparation. After the harvest of the former crop, two plows were used to pulverize the soil, 2000-3000 kg of Mushi farmyard fertilizer, 50 kg of phosphate fertilizer, and 15-20 kg of potash as base fertilizer. Sinking and sowing, 200 cm open, 30 cm wide, 20 cm deep.
(c) timely sowing. 1, seed treatment. Sowing before sowing or soaking in warm water (flush with 55-60°C hot water, stir constantly, disinfect and sterilize), soak the seeds for 5-6 hours until the water temperature drops to 30°C. With a clean wet gauze wrapped for germination, the seeds begin to germinate and can be sown. 2, timely sowing, rational close planting. Sowing time is from late December to January. Planting density should be based on species characteristics, cultivation methods, soil fertility and determined: cucumber 3200-4400 ponds per acre; climbing cucumber 2200-2700 ponds per acre.
(d) Field management. 1, fertilizer and water management. Before the flowering, the cucumber needs less water, and it needs more water in the result period. According to this characteristic, irrigation is reasonable. Cucumber is hi-fertilized, but its root system has weak absorption and is sensitive to high-concentration fertilizers. It is recommended to apply multiple fertilizers at low concentrations. Nitrogen fertilizer was the main seedling stage, combined with nitrogen, phosphorus and potassium in the middle and later stages. At the same time, 0.3% potassium dihydrogen phosphate was sprayed 2-3 times. 2, plant adjustments, scaffolding. About 30 centimeters in length, should be set up home (personal frame) or vines. The introduction of vines and vines should be carried out several times with the growth of the plants so that the vines crawl relatively regularly without overlapping. Early maturing varieties of cucumbers grow early in the main vine, generally leaving only 1-2 branches. Late-maturing varieties of fruit on the side of the vine spread early, so early varieties do not topping, late-maturing varieties should be 5-6 leaves topping, promote side vines, early fruiting vines, generally leaving side vines 3-5. 3, pest control. (1) Downy mildew, powdery mildew, blight, anthrax: 75% chlorothalonil 600 times, 42.2% promemidone 1000 times, 60% aluminum phosphate 350 times, 80% anthrax 500 times Liquid control; (2) virus disease: with 1.5% of the plant disease Ling 1000 times, 20% poison fly 600 times control; (3) aphids: with 10% imidacloprid 2000 times, 2.5% kung fu 3000 times.
