In the Gaotian field in the middle and lower reaches of the Yangtze River, when early rice was harvested, it was often impossible to plant late rice due to inconvenient irrigation. However, if the rice-cucumber crop rotation is implemented, the output value of 3500-4000 yuan and net profit of 2500-3000 yuan can be achieved only by autumn cucumber, and the pests and diseases of both crops will be reduced. 1. Carefully choose the land: Use paddy soil, water source is not contaminated, and away from the source of pollution more than 2 kilometers, the soil is deep, fertile, loose, and clean water irrigation and convenient transportation. 2. Variety selection: Use high-yield, high-quality, strong resistance and pest resistance varieties, such as Jinyan No. 4, No. 2, No. 7, and Jinza No. 2. 3. Careful site preparation: Spread 2500-3000 kg of decomposed manure per acre, 60 kg of compound fertilizer for vegetables, and 40-50 kg of quicklime powder (or 50 kg of biofertilizer for high-efficiency vegetables). 40-50 kg of quicklime powder is used as base fertilizer, and it is turned twice more. It is a deep groove sorghum with a width of 1m and a width of 30cm. Basal fertilizers are banned from fertilizers containing chlorine and nitrate. 4. Timely sowing: The rice growing area in the middle and lower reaches of the Yangtze River can be seeded or transplanted in the middle or late August. Sowing before sowing for 1 day, then soaking in warm water of 50-60°C for 15-20 minutes, and continuously stirring; when water temperature drops to 25-30°C, add 0.1% carbendazim or 1% quicklime powder to soak seeds for 4-5 hours, then Rinse out 2-3 times with clean water and remove impurities and ill varieties. When planting, sow 2 lines per hole, 30 cm from the hole, 2-3 seeds per hole, and sow 4000 points per acre. Then evenly cover the thin soil, pour enough water, cover with straw and other coverings to cool and moisturize. 5, fertilizer and water management: Qimiao after the topdressing 1 quick-effective Miao Fei. When 3-4 leaves are true, Mushi applies excrement 500 kilograms; when 6-7 leaves are applied, 1 500-kilograms of human fecal urine water and 5-8 kilograms of high-efficiency vegetable compound fertilizer are applied as top dressing. From the beginning of harvesting, the management of fertilizer and water should be done with groundwater irrigation, and the amount of fertilizer should be light and heavy. In the full fruit period, 2-3 times of top dressing is harvested. The removal of plant ash after irrigation or after rain can control the disease. After each harvest, the seedlings were sprayed with 0.3% potassium dihydrogen phosphate plus 0.1% urea solution once. 6, plant management: timely release after the emergence of rice straw and other coverings, do a good job of seedling seedlings, combined with 1-2 times between the cultivator. 6-7 pieces of leaves when the real frame, cited vines, tied vines, the removal of tendrils and root vines below the lateral vine, the upper side of the lateral vines can leave 1 melon 1 cranberry topping heart; when the plants reach a suitable height, remove the main vine top heart. In the middle and late period, most of the old and disabled leaves were removed and the thinning and fruit thinning were timely. Spraying paclobutrazol for 1 time at the seedling stage can promote the development of thick stems and thick roots, and improve drought resistance and cold resistance in the later period. 7. Pest Control: Through the use of water and dry crop rotations, agricultural pest control measures such as disease resistance and pest control, as well as fertilizer and water management were used to effectively reduce pests and diseases. If it is necessary to prevent and control, please use low or non-toxic biological pesticides and prohibit the use of all highly toxic and high-residue pesticides.
