Problems solved by technology

[0003] Intercropping of wheat, peanuts and corn is an intercropping model of leguminous crops and gramineous crops. It used to have a large planting area in Shandong, Hebei, Henan, Shanxi and other places. However, due to the early interplanting of peanuts, most of them formed ridges. It is labor-intensive and time-consuming, and it is not suitable for mechanized operations. It requires a lot of labor, and the planting area is gradually shrinking.
[0004] At the same time, with the advancement of modern breeding technology, various breeding industries have formed large-scale and systematic production, which has caused certain difficulties in the use of farmyard manure. In addition to fertilizing the soil, only relying on the application of chemical fertilizers is very likely to cause land environmental pollution, soil structure damage, great waste and damage to land resources, soil nutrient loss or insufficient utilization, low agricultural production and planting efficiency, and release of production capacity insufficient

Abstract

The invention discloses a wheat, soybean, peanut and corn intercropping planting method which comprises the following steps: 1) at the beginning of October of the first year, applying a fertilizer toa planting land, and mechanically sowing wheat by alternately arranging eight rows of narrow rows and four rows of wide rows; 2) broadcasting and intercropping five rows of peanuts among four rows ofwide rows and on two sides of the wheat in May 20th to May 31st in the next year; 3) harvesting wheat from June No.1 to June No.10 in the second year, and sowing 3 rows of corn among 8 rows of narrowrows after the wheat is harvested; 4) planting one row of soybeans between every two rows of corns in June No. 15-No. 25 of the second year; and 5) harvesting peanuts and soybeans in September 20th toSeptember 25th of the next year and harvesting corns in September 26th to September 30th of the next year. The method not only can fully utilize land resources, but also can reduce the use amount ofchemical fertilizers, reduce the influence of the chemical fertilizers on the ecological environment, reduce the agricultural production cost and improve the fertility of soil at the same time.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to an intercropping planting method of wheat, soybean, peanut and corn. Background technique [0002] With the continuous growth of population and the rigid growth of food demand, intercropping has attracted more and more attention and discussion of domestic and foreign agricultural experts. Intercropping is the essence of traditional Chinese agriculture, has a long history, and has made great contributions to both traditional and modern agriculture. A reasonable intercropping model can intensively utilize natural resources such as light, heat, fertilizer, and water, and is also one of the effective measures to increase biodiversity in farmland, enhance crop resistance to pests and diseases, and lodging resistance, and increase productivity per unit land area. [0003] Intercropping of wheat, peanuts and corn is an intercropping model of leguminous crops and gramineous crops....
