Wheat-corn relay interplanting planting method

Abstract

The invention relates to the technical field of agricultural planting, and discloses a wheat-corn relay interplanting planting method. In the method, a mode of alternating wheat planting zones and corn planting zones is adopted, and wheat is planted before corn is planted; four rows of wheat are used as one planting zone; row spacing between the second row of wheat and the third row of wheat ranges from 25 to 35 centimeters in the planting zone, and the row spacing between the rest two adjacent rows of wheat is 20 centimeters; an empty row with the width of between 125 and 135 centimeters is reserved between the two wheat zones and is used for planting the corn zones; two rows of corn are used as one planting zone; row spacing among corn is 45 centimeters; and the space between the adjacent corn and wheat ranges from 40 to 45 centimeters. By the method, the row number of planting the wheat is reduced, and the wheat is planted in a mode of wide-narrow row spacing, namely compared with the original row spacing, the row spacing of the corn is reduced by 5 centimeters, so the space between the wheat and the corn is increased; and the planting environment of intergrowth period of the wheat and the corn is optimized, the shading effect of the wheat on the corn is relieved, and the specific yield and yield per unit area of both the wheat and the corn are improved simultaneously.

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...
