Double-row sparse planting method for interplanting corn in cornfield

Abstract

The invention discloses a double-row spaced planting method of corn inter-planting in corn field; the number of total rows of double-row spaced planting is more than the number of total rows of single-row planting by one time; the seedling is positioned in double rows by adopting an alternating method and the number of the left seedling is increased by 10 percent to 20 percent compared with the equal row spacing type. The double-row spaced planting method of the invention not only can improve the corn yield but also fully utilizes the illumination resource and utilizes the land resource reasonably.

Description

technical field [0001] The invention relates to agricultural planting technology. Background technique [0002] For a long time, the planting specifications of field corn in my country are generally large and small rows or equal row spacing. The large and small rows are mainly used for interplanting corn in wheat fields. They prevailed in the 1970s and 1980s, and played a certain role in promoting the transition from low-yield to middle-yield corn yields. However, this method has a low land utilization rate. The yield of wheat is affected due to too large furrows, and the density of corn is difficult to increase due to too large row spacing, which has become an obstacle to the transition from medium yield to high yield of corn interplanted in wheat fields. [0003] With the improvement of productivity level, at present, interplanting corn in wheat fields mostly adopts interplanting rows with equal row spacing, and the average row spacing of corn is gradually reduced from 90...

AI Technical Summary

Problems solved by technology

[0004] At present, interplanting corn in wheat fields still has the defect that the row spacing is too large. If the row spacing is too large, there will be light transmission, which cannot make full use of light resources and rational use of land resources.
