Abstract

The invention relates to the technical field of agricultural planting and discloses a wheat-corn interplanting method. According to the wheat-corn interplanting method, wheat planting belts and corn planting belts are arranged in a alternate mode, wheat is planted prior to corn and at 4 rows each belt, the interval between the second row and the third row of every belt is 25-35 cm, the interval between every other two neighboring rows is 20 cm, and unplanted rows 125-135 cm wide are reserved between every two neighboring wheat planting belt for planting the corn belts; corn is planted at 2 rows each belt, the interval between every two neighboring rows is 45 cm, and the interval between neighboring corn and wheat is 40-45 cm. The wheat-corn interplanting method reduces the number of planting rows of wheat, achieves different planting row widths and reduces corn planting interval by 5 cm, thereby increasing the interval between wheat and corn, optimizing the planting environment during interplanting period of wheat and corn, reducing the shading effects of wheat on corn and meanwhile improving the yield per unit or wheat and corn.

Description

technical field

[0001] The invention relates to the technical field of agricultural planting, in particular to a wheat-corn intercropping planting method. Background technique

[0002] The four southwestern provinces (cities) of my country, Sichuan, Guizhou, Yunnan, and Chongqing, have a lot of people and little land, with a large proportion of dry land in hills and mountainous areas, and a high degree of multiple cropping. They are typical dryland and multi-crop agricultural areas in southern my country. The so-called multiple cropping refers to the planting method of continuously planting two or more crops on the same field in one year, such as wheat-jade twice a year, wheat-cotton twice a year, wheat-rice-rice three times a year, etc. ; In addition, there are three crops in two years, five crops in three years, etc. After the last crop is harvested, in addition to directly sowing the next crop on the ground of the previous crop, regeneration, transplanting, intercropping...
