Sowing method capable of controlling extending directions of corn leaves

Abstract

The invention provides a sowing method capable of controlling extending directions of corn leaves, aiming at decreasing the shading area among the corn leaves in case of thick planting, and overcoming the defect of insufficient illumination in case of production increase by thick planting. The sowing method comprises the following steps that: when seeds are sown, the flat surfaces of seeds sown in the soil are arranged on the horizontal plane, the direction of connecting lines between the tips of the seeds and the long-axes middle points of the oval-shaped development of the tops of the seeds are accordant with the extending directions of the corn leaves, or the tips of the seeds sown in the soil vertically face downwards, the tops of the seeds are upward, and a right angle exist between each flat plane of the seeds or the long axis of the oval-shaped development of the top of each seed and the extending direction of each leaf as required by sowing workers. The sowing method has the benefit effects that due to the manual measure, the extending directions of the corn leaves can be controlled, the randomness of the extending directions of the conventionally sown plant leaves can be changed, the insufficient illumination caused by the increase of the leaves density can be avoided, the corn cultivation density can be further improved, and the foundation can be laid for improving the yield per unit of corns.

Description

technical field [0001] The invention belongs to agricultural technology, and in particular relates to a corn sowing method. Background technique [0002] Maize is an important food crop, and improving the yield per unit area of ​​maize is an important subject of maize scientific research. Maize belongs to the monocotyledonous plant of Poaceae. The leaf is one of the important vegetative organs of maize. Its main function is to perform photosynthesis and transpiration. The leaf produces light and products through photosynthesis, providing material sources for the growth of various organs of the plant. The leaves grow alternately on the stalk, and only one leaf is born at each node, and they are arranged in two rows alternately on a plane. Reasonable dense planting is one of the important measures in the high-yield cultivation measures of corn. Studies have shown that the planting density of maize directly affects the leaf area index, and then affects the yield. Therefore, ...

AI Technical Summary

Problems solved by technology

However, in the past corn planting, because each corn leaf stretched in different directions, when the leaf area increased to a certain limit, the leaves covered each other, so that the individual light was insufficient, the photosynthetic efficiency was weakened, and the yield decreased instead.
