Peanut Interplanting Sweet Potato Cultivation Technology
Peanut interplanting sweet potato is an effective way to solve the contradiction between grain and oil, increase the yield of sweet potato, and is also one of the important measures to increase the total grain output. After many years of planting and verifying, the interplanting of potato generally yields 100-150 kilograms of dried sweet potatoes compared with peanuts. Since the potato seedlings are inserted earlier, the period of growth is prolonged, and the wind damage is reduced and the drought resistance is enhanced, so that the advantages and benefits are avoided and the yield is increased. one. Interplanting method 1. Ridging and gullies are interplanted: 99 cm wide ridges and ridges, and peanuts are planted in separate trenches. A ditch two ridges next to a variety of 1-2 rows of peanuts, 1-2 per hole. Sweet potatoes in this way can be inserted in the early flowering period of peanuts, as well as early plough-side dressing. This method is suitable for use in mountain gardens, foreign gardens and drylands. 2. Rigging stays in the middle of the set of potatoes: ridge broadband 99 cm, ridge top stay lined potato, ridge on both sides (two-thirds of the ridge height) all kinds of row of peanuts. This method is suitable for low flat wear. 3. Stay on the side of the set of potatoes: 畦 99 cm wide groove, while leaving 26.4 cm to insert the potato, and the other side of the 3 rows of peanuts. This method is easy to insert the potato when you can turn plough soil loose heart, and easy farming. This method is suitable for use in mountain gardens and drylands. Second, supporting technology l. A reasonable mix of varieties: In order to reduce the mutual influence of symbiosis between peanuts and sweet potatoes, we should use dwarf varieties of early-maturing high-yield and stable peanut varieties, such as flower 11, white sand 1016 and so on. Selected varieties of short-cropped upright sweetpotato varieties such as Jinshan 57 and Fushu 87. 2. Early sowing in due course, regular inserts: Peanuts generally strive to sow in mid-April. The insertion of sweet potatoes is generally conducted in the middle or early June, that is, before the pinning period of peanuts, the peanuts are sown 50 days after sowing. 3. Reasonable dense planting: The suitable density of peanuts, potato spacing (single line) 7.26 to 8.25 cm, (multi-line) 13.2-16.5 cm is good, to ensure that the number of acres per plant is 15,000 about. Sweet potato spacing 16.5 to 19.8 centimeters, to ensure 3000-3B00 Mu insert. 4. Apply basal fertilizer to catch sweet potato clip-side fertilizer: Before planting peanuts, use farmyard fertilizer as the main fertilizer and apply fertilizer to the base fertilizer. The fertilization method is based on the combination of paving and pitting. After the sweet potato cuttings, the sweet potato clip edge fertilizer should be followed. 5. Strengthen the field tube: The slope of the peanut ridge in the ridge-line planting line is large, it is difficult to insert the soil under the needle, and in the next needle period, the soil should be ditched in time to remove the weeds. In the rainy season, the water in the ditch should be promptly removed, and timely irrigation and drought relief should be provided. Immediately after the peanuts were harvested, the sweet potatoes were chaffed and soiled. And timely control peanut, sweet potato common pest Spodoptera litura, cotton bollworm and so on.
