Method for planting corn according to plant height of corn plants by utilizing circumference ratio

Abstract

The invention discloses a method for planting corn according to the plant height of a corn plant by utilizing a circumference ratio. The method comprises the following steps: determining the local expression plant height of a corn variety; determining the planting line spacing according to the planting height, wherein the line spacing is equal to the ratio of the plant height to the double pi value, that is, the line spacing = the plant height (cm) / 2 * pi = the plant height / 6.28, and the unit is cm; determining the planting row spacing according to the planting density and the planting line spacing, wherein the line spacing and the row spacing are arranged in an area to be planted, and the row spacing meets the following conditions that the row spacing is equal to the area per mu / (density* line spacing), namely the row spacing is equal to 666.7 / (density * line spacing), and the unit is cm; and carrying out corn planting according to the determined line spacing and the row spacing mode. The planting line spacing is scientifically and reasonably determined, quantitative row spacing is achieved, the light, temperature and gas conditions in the field are remarkably improved, and sustainable and stable development of corn production is promoted; better balance among crop field moisture, illumination, nutrients and land utilization is achieved, and the purpose of increasing the yield is achieved.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for planting corn plants by utilizing the circumference ratio. Background technique [0002] Planting density has become one of the main factors that determine the yield of corn. With the improvement of the density tolerance of corn varieties and the increase of planting density, in many aspects of corn cultivation technology, the first thing to consider is to determine the planting method to achieve the yield per unit area of ​​corn One of the problems is how to make a reasonable spatial layout, so that under high-density planting, improving the utilization efficiency of light, heat and other resources becomes the most feasible method to increase yield. According to research reports, different row spacings, different densities, and the interaction between row spacing and density have reached extremely significant differences, indicating that there are extremely significant ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of planting row spacing, and provide a method of planting according to the height of corn plants using pi that is simple to operate and does not increase production costs. By scientifically and rationally determining the planting row spacing, the field light, temperature and air conditions are significantly improved. , promote the sustainable and stable development of corn production; solve the technical bottleneck problem of "uniform height" in crop planting, and realize "measurement and fixed spacing", that is, determine different planting row spacing according to different plant heights, so that the moisture, light, nutrients and A better balance between land uses can be achieved to increase production
