In the second season, the intercropping potato should be selected as early-maturing swollen varieties. The spring potato cultivation should adopt the film mulching method to shorten the symbiotic period with other crops as much as possible, and alleviate the contradiction between water, fertilizer and cultivation management during the symbiosis of the two crops. Second, choose the right cultivation method 1. Intercropping between potato and corn, in order to solve the problem of corn shading, 2:2 planting method can be used, that is, two rows of potato and corn, the row spacing is 30 cm, each is 120 cm wide, the potato plant spacing is 20 cm, the potato and corn density It is 3,700 plants per mu. For high-stalk corn, 3:2 planting method can be used, that is, three rows of corn and two rows of potatoes. The row spacing of corn is 40 cm, the plant spacing is 30 cm, the row spacing of potatoes is 60 cm, the plant spacing is 20 cm, and the row spacing of potato and corn is 30 cm. The density of centimeters, potatoes and corn is 3,333 plants per acre. 2. Potato and cotton intercropping, generally potato is about one month earlier than cotton, and the symbiotic period is short. It is a good match. It is suitable to adopt 2:2 cultivation method. The potato row spacing is 60 cm, the plant spacing is 20 cm, and the potato and cotton are used. The distance between the two is 40 cm, each width is 180 cm, and the density of potatoes and cotton is 3,700 per acre. Third, the spring cultivation attention to solve the water demand conflict Potatoes are colder than other crops, planting earlier than other crops, and need to be watered after emergence, so that pre-watering of potatoes will reduce soil temperature and affect the emergence and seedling growth of cotton, corn and other crops. Therefore, when watering must be done, Small water is poured between the two rows of potatoes. Disclaimer: Some articles on this website are transferred from the Internet.
