High-yielding Planting Techniques of Peanut in Red Soil Dryland
The red loam in China's land exists in many areas, and peanuts are common crops in China. However, peanuts are planted in red loam soil, and long-term single cropping is repeated, causing many pests and diseases to occur, resulting in a decrease in peanut yield. How to effectively and high-yield peanuts Let's take a look at the following. I. Seed selection and seed treatment At present, peanuts grown in large areas of red loam are many old varieties and are highly degraded, so we must effectively select them. Early and medium-ripening peanuts with high disease resistance and drought resistance, such as Yueyou No.7, Oyster Oil 27, Zhongkaihua No.1, Hanghua No.2, etc. Before planting, it can be sown with a seed coating agent or seeded with 2 g/kg of ammonium molybdate plus 0.1-0.2 mg/kg of brassinoside, or 70% carbendazim seed dressing. Second, soil preparation and fertilization Before planting, it can be finely grounded and ditched. 60 kg of compound fertilizer or 30 kg of compound fertilizer and 30 kg of compound fertilizer are used as base fertilizer. Red soil soil acid soil, poor water retention and drought resistance, can supplement calcium magnesium phosphate fertilizer and trace element fertilizer, effectively reduce the peanut shell rate, 50-75 kg of calcium magnesium phosphate fertilizer, 0.5 kg of borax, 1 kg of zinc sulfate, conditional Follow the silicon fertilizer. Third, timely early broadcast Spring sowing peanuts in a timely manner, can effectively avoid the drought, which is conducive to the maturity of peanuts. However, too early sowing will lead to rotten seedlings, so time should be mastered. Generally, the sowing period from Weinan to Weibei is from late March to mid-April, and mulching cultivation can be sown 5-7 days earlier. The seeding amount per hole is two. Before sowing, the surface layer can be sprayed with acetochlor or Jinduer according to the type and damage of the weeds in the past to prevent weeds. Fourth, field management Mainly pay attention to these several field managements, which are post-emergence seedlings, clearing ditch drainage, seeing seedlings and fertilizer control. Peanut seedlings are generally seeded and replanted after 10-15 days. Peanut seedlings have a lot of rain. If you don't open the ditch, it will easily lead to dead seedlings, so pay attention. Peanut is a favorite fertilizer crop. Topdressing can effectively ensure the growth of peanut seedlings and increase yield. V. Pest Control Peanut pests and diseases have a great impact on yield. The main diseases of peanuts include leaf spot, rust, bacterial wilt, stem rot, virus disease, etc. Initially available, benzidine, prochloraz, thiazolamide, methyl The agent such as thiophanate is used for prevention and treatment. The pests mainly include aphids, aphids and Spodoptera litura. They can be controlled by acetamiprid, lambda-cyhalothrin, avermectin and carbaryl. The underground pests are mainly cockroaches, golden worms and small tigers. Acre phoxim granules or thiazolyl granules, mixed with fine soil and sprinkled in the seeding ditch. Peanut planting is high-yielding. It is very important to do these management points. Regardless of the seedling stage or the growing season, if the peanuts grow healthily and vigorously, then the later production will definitely go up.
