The use of paddy fields to grow spring potato, spring corn, Chinese cabbage, can receive three kinds of high efficiency. The cultivation points are now described as follows: One, spring potato 1. Cut and germinate. Choose early and mid-maturing varieties, and prepare 125-150 kg of potatoes per acre. About 20 days before sowing, the large pieces of seed potatoes are cut into small pieces of 20-25 g, each piece leaves 1-2 buds, and then put into a greenhouse or indoor temperature of 17-20 °C, humidity of about 70% germination. When the buds are about 1.5 cm long, they can be sown. 2, suitable for sowing. Spring potatoes should generally be sown in mid-December-January. Before sowing, the land was integrated with ploughing, drainage ditch was opened, and the width was 2 meters wide. The width was 1.7 meters and the width was 0.3 meters. And after row spacing 45 cm (4 lines per trip) after the excavation of the sowing ditch, the Mugou applied three elements of compound fertilizer 50 kg, 1,500 kg of human and animal dung, 75 kg of superphosphate, 10 kg of dried cake fertilizer as base fertilizer, base fertilizer cover a A layer of finely ground soil about 3 cm thick is planted and then planted at a spacing of 20 cm. After sowing, it is planted with grass ash or fire-soil ash to cover 7 cm thick and about 5000 plants per mu. 3, field management. After sowing, after the advent of low temperature, choose a warm and no rain weather spray 1 herbicide liquid to prevent weeds from covering the film, from late February to early March, when the potato seedlings grow to 7-10 cm, the plastic film will be removed. 5-7 days after uncovering the film, combined with cultivator weeding, earth hoeing, 1,000 kilos of animal manure, or 25 kg of ammonium bicarbonate, watered and applied to the plant. Potato down seedling period, mu 50 grams of paclobutrazol 60 kg sprayed across the field to control the promotion of the next. In early flowering, full flowering, and final flowering periods, thin manure, livestock and manure water is poured. During rainy season, ditches should be drained in time to prevent surface waterlogging. The tuber period is the formation period of tuber yield. It is necessary to keep the soil moist and promote high quality and high yield. Second, spring corn 1, suitable for sowing. Select high-quality, high-yield, disease-resistant sweet corn varieties or waxy maize hybrids. The sowing date should be considered comprehensively according to the harvest period of spring potatoes. Generally, the cultivation of seedlings with nutrients is adopted. The seeds can be sown in early April, transplanted in late April, and harvested on the middle and early July. Transplanting leaves are about 2.5-3 leaves, spacing is 47 cm, plant spacing is 25 cm, and about 4000 plants are planted in acres. 2, fertilizer and water management. When the hole was transplanted, 50 kg of compound fertilizer was used as base fertilizer. 5 mus of 10 mu of urea and 15 kg of potash are mixed with water. Tasseling period mu grain full 50 grams watered 40 kg sprayed on the top leaves, can also be sprayed with 0.2% urea solution or 800 times potassium dihydrogen phosphate solution, can play a strong seed and anti-fertility premature aging effect. During the seedling stage, the trenches will be drained and drained. In the middle and late periods, furrow irrigation should be carried out in time to keep the soil moist and meet the water requirement of corn grouting. 3, pest control. Before the transplanting, soil preparation was carried out by using 2 mg of carbofuran granules per mu and 5 kg of fine sand mixed in the bottom of the planting hole to control insect pests such as ground tigers. The small bell mouth mu with 3% of phoxim granules 0.5 kg and 7.5 kg of fine sand, spread in corn leaves, prevention of corn borer and sheath blight and so on. Third, cabbage cultivation points 1, sowing nursery. The seedlings are planted in late July-early August and the seedbed is 2.4 meters wide, depending on the terrain. Carbofuran 0.1 kg per 20 m2 seedbed, 1 kg urea, 100 kg farmyard manure, deep turning and mixing, levelling and fine detailing, and then splashing 150 kilograms of human waste water, soaking the wet surface, soaking the water after sowing, After sowing, the grass ash or finely smashed soil is 2 cm thick. After emergence, depending on the situation, watering, seedlings, shade nets and pest control to keep the soil moist and promote Miao Miao. 2, fine transplanting. Ten to fifteen days before transplanting, pick sunny plowing, bake the soil white, and then do the earthwork. It is 4 meters wide and 0.4 meters wide. Mu Shi 1,500 kg of livestock manure, 100 kg of compound fertilizer, 20 kg of potassium fertilizer as base fertilizer. About 13 days after sowing, 3-4 seedlings of Chinese cabbage seedlings were planted at the time of planting. The plant and row spacing were 45 cm, and about 1,500 acres were planted. Before spraying, foliar spraying was performed with a concentration of 0.01% streptomycin solution to control cabbage soft disease. 3, strengthen management. Immediately after transplanting, the water was poured 1 time each day until the seedlings became alive. After the seedlings became alive, they applied 1 thin manure and livestock manure water. The lotus seedlings were irrigated with 15 kg of urea and watered. The ball stage was combined with applying 10 kg of urea. For insects such as cabbage caterpillars and beetles, they can be controlled by agents such as Wanling and Yetaibao; they can be used to control soft rot; they can be used to control downy mildew; carbendazim can be used to prevent black rot, and can be used to prevent and treat diseases. Manganese zinc. At the same time, do a good job of flood control and weeding. Disclaimer: Some articles in this website have been transferred from the Internet.
