High-yield and high-efficiency planting method for conducting wide-width interplanting on summer corn and summer peanuts

Abstract

The invention aims at providing a high-yield and high-efficiency planting method for conducting wide-width interplanting on summer corn and summer peanuts. By the adoption of the method, fertilizer input and pesticide input are reduced, the land utilization rate is improved and the oil-plant production increase is achieved on the premise that food security is ensured. The method includes the following steps that field blocks are selected; pre-sowing preparation is carried out, wherein after wheat harvest and before ploughing, a high-quality decomposed organic fertilizer of which the dosage is 2000-3000 kilograms per mu is applied, a composite fertilizer containing 15 kilograms of nitrogen fertilizer, 15 kilograms of phosphate fertilizer and 15 kilograms of potassium fertilizer is applied, the dosage of the composite fertilizer is 50 kilograms per mu, after the ploughing, rotary tillage is conducted on over 30 centimeters of soil, harrowing and levelling are conducted along with the tillage, straw, stones and other sundries are removed, and the purposes that the field is flat, the soil is fine and the fertilizers are applied evenly; sowing is conducted, wherein after the sowing, with the addition of four kilograms of water, 50% carbendazim wettable powder of which the dosage is 0.3-0.5% of the seed weight and 50% phoxim of which the dosage is 0.2% of the seed weight are adopted to sprinkle peanut seeds, and airing is carried out; after the wheat harvest, harrows are rapidly made and early sowing is conducted, wherein the early sowing is completed before June 20th; peanut seeds are sowed; corn seeds are sowed; interplanting field management is carried out.

Description

technical field [0001] The invention relates to a crop planting method, in particular to a high-yield and high-efficiency planting method of summer maize and summer peanut in wide-width intercropping, and belongs to the technical field of crop production. Background technique [0002] Food is the foundation of human survival and social progress, and the lifeblood of the economy. China is the most populous country in the world and has a huge demand for food, and the supply and demand have been in a state of tension. [0003] The intercropping method can not only make intensive use of agricultural resources and improve the compound productivity per unit area, but also an effective measure to increase the diversity of crops in the farmland. Wide-width intercropping of corn and peanuts has the advantages of symbiotic nitrogen fixation, high resource utilization, improved soil environment, and enhanced population stress resistance. However, there are problems of declining peanut...

AI Technical Summary

Problems solved by technology

Wide-width intercropping of corn and peanuts has the advantages of symbiotic nitrogen fixation, high resource utilization, improved soil environment, and enhanced population stress resistance, but there are problems of declining peanut yield and insignificant increase in output value. Therefore, reasonable planting methods are needed to promote intercropping of corn and peanuts Yield increase
