One-empty-in-two-ridge corn planting method

Abstract

The invention relates to a one-empty-in-two-ridge corn planting method. The method comprises the following steps: (1) preparing land; (2) selecting seeds; (3) performing coating; (4) sowing according to a one-empty-in-two-ridge method; (5) applying fertilizer, using BB fertilizer or slow/controlled-release fertilizer according to a detection result; (6) irrigating; (7) performing field management; (8) harvesting. Compared with the prior art, the beneficial effects of the method are that the method is characterized by simple, scientific, and rational, and the method effectively uses an empty ridge method to realize a marginal effect, so as to increase field ventilation and light penetrating amount and improve growing environment of corns, the method uses a high photosynthetic efficiency principle to realize a planting mode of ridges are border rows and plants are land, thereby improving utilization rate of illumination and accumulated temperature; since fertilizing amount is concentrated, being beneficial for corns to fully absorb intensively, thereby improving utilization rate of fertilizer, preventing problems of excessive or insufficient fertilization, improving corn yield and cultivated land quality, and the method has wide promotional value.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for planting double-pitch corn. Background technique [0002] Corn is one of the most important food crops in the world today. Its planting area and total output rank second after wheat, and it also ranks second after rice in China. The development trend of corn production can be roughly divided into four types: the first One category, the planting area increases, the yield per unit area increases, and the total output increases significantly. Representative countries are China, Brazil, Mexico and the United States. The second category is the reduction of the planting area, and the increase of the total output by increasing the yield per unit area, such as Argentina, Thailand, India and other countries. The third category is that the planting area is basically stable, and the total output is increased by increasing the yield per unit area. France is a typical example....

Problems solved by technology

The fourth category is that the planting area has decreased, and the yield per unit area has also declined, resulting in a significant reduction in total output. Romania and Yugoslavia belong to this type

[0004] There are various cultivation methods of corn, but not all cultivation methods of maize can achieve high yield. The main problems are careless seed selection, unscientific fertilization, unreasonable planting density, untimely watering and lack of field management techniques. Climatic conditions such as light, wind, and temperature all affect the photosynthesis, respiration, growth, development, and source, flow, and sink transportation of corn. Although the wind speed cannot be controlled at present, the corn field can be adjusted by suitable planting methods. The group structure better solves the contradiction between density and ventilation and light transmission, improves the light energy utilization rate of corn, and will surely achieve the effect of increasing production
