High-yield and High-efficiency Cultivation Techniques of Potato Brassica spinach
First, the mouthwash arrangement Potatoes sowed in early March, harvested in late May, the general yield of 1000-2000 kg; cabbage planted in early May seedlings, planting in early June, harvest in mid-August, yield 1500-2000 kg; Spinach is sown in late August and harvested in late September and early October. The yield per mu is 2000-3000 kg. The radish is sown in mid-October and harvested in January of next year. The yield per mu is 2,500-3,500 kg. Second, cultivation points (a) potato selection of early maturation, high yield, adaptability varieties such as Dongnong 303 and so on. Before sowing, the large and well-selected large potatoes were cut into pieces. Mu Shi decomposed organic fertilizer 2500 kg, 30 kg of potassium sulfate, fine soil preparation for earthworms, the width of 80 meters wide, 30 cm wide groove, pouring a good bottom water. In early March, sowing, sowing 2 lines per line, row spacing 40 cm 15 cm, covering 5 cm after sowing, and then cover the film, with soil tight. Seedlings emerged in time when they emerged. Qi Miao 10 days later, acres of urea 6 ~ 10 kg. When the height of seedlings is about 30 cm, the soil will be high and the height will be double-ridged. When a walnut-sized potato block is formed underground, it should be treated with waterlogging, watering should be stopped 10 days before the harvest, and timely prevention and control of late blight, aphids, spider mites and other pests and diseases. (b) Cabbage use early maturing, heat-resistant, disease-resistant varieties. After the potato was harvested, Mushi rotted 4000 kg of organic fertilizer and 50 kg of compound fertilizer. The soil was finely grounded, and the width was 100 cm and the width was 30 cm. Summer cabbage is planted in early May. The seedlings are transplanted at 25-30 days and the plant spacing is 40 cm and 33 cm. Each row is planted with 3 rows. After planting, water is poured to set the root water. After slowing the seedlings, the Mushi lightness of 100 kg of human and animal manure water, the amount of urea in the lotus stage is 10 kg, the urea of ​​the ball is 15 kg, the potassium sulfate is 5 kg, and the ball is knotted. Pre-moisture should be sufficient, and watering should be properly controlled in the later period. Timely control of pests such as vegetable lice and cabbage worms. (3) Spinach uses heat-resistant, fast-growing, and non-convulsive varieties. After cabbage was harvested, Mushi applied 3,000 kg of organic fertilizer and 30 kg of compound fertilizer. Plowing the soil preparation and planting seedlings, when the seedlings 1.5-2 leaf time seedlings, at the same time, the mu will be applied with 10 kg of urea and 10 kg of potassium chloride. When 5 leaves were used, a total of 20 dry grams of compound fertilizer was applied to the water. Pay attention to keeping the soil moist during the growing season, pouring water once every 3-4 days, and timely controlling pests and diseases. (D) radish spinach after harvest, 40 kg of Mushi compound fertilizer as a base fertilizer, starting in mid-October, planting disease-resistant, high yield of spring is not an old radish, pouring water after sowing, and strive to broadcast a full seedlings. In 1-2 true leaf time seedlings, 3-4 true leaves are seedlings, combined with cultivating and weeding. In the period of leaf growth, it is necessary to re-apply a fertilizer, 20 kg of potassium chloride in Mushi, 10 kg of urea, and ditching, applying soil after application. After the radish sprouts, a 2% superphosphate solution was applied once a week to the foliage.
