Corn planting method

A planting method and corn technology, applied in the fields of botanical equipment and methods, horticulture, application, etc., can solve the problem of root growth, lodging resistance, surface water evaporation rate and nighttime temperature emission, which are unfavorable for corn growth, increase corn planting density, and ventilation. It can improve the ventilation and light transmission performance, facilitate the balanced application of nutrients, and improve the utilization rate.

Problems solved by technology

[0002] The traditional corn planting method is a single plant cultivation method in one hole. Due to various conditions, generally 4200-4700 plants / mu, therefore, the root growth of crops, lodging resistance, corn pollination opportunities, surface water evaporation rate and night temperature Dispersion is not conducive to the growth of corn, resulting in the disadvantages of low yield and poor grain quality in this planting method.
Increasing the planting density of corn will cause problems such as poor ventilation and light transmission, and no wind resistance.

Abstract

The invention discloses a corn planting method, which comprises the following steps of: soil preparation, seed selection, sowing, fertilizer application, and thinning. The step of sowing adopts the following method that: the seed row width is 80 to 90cm; three holes form a planting group in each seed row, and the group distance is 28 to 35cm; and the hole distance is 2 to 4 cm in each planting group, and a single plant is planted in a single hole. The planting method is favorable for balanced application and corn absorption of nutrient; the root systems between each group of plants are crossed and supported each other; ventilation can be carried out between the plants; the pressure of wind on the plants is weakened; wind can pass through the groups; and the lodging can be effectively prevented. Potential competition causes multiple strong roots of the corn and is favorable for absorbing nutrient; and the relatively centralized fertilizer application improves the utilization ratio of chemical fertilizers. The corn planting method is tested somewhere in Hebei Province for three years, and the yield increase rate can reach 30 to 50 percent.

Description

technical field [0001] The invention relates to a food crop cultivation technique, in particular to a corn cultivation method. Background technique [0002] The traditional corn planting method is a single plant cultivation method in one hole. Due to various conditions, generally 4200-4700 plants / mu, therefore, the root growth of crops, lodging resistance, corn pollination opportunities, surface water evaporation rate and night temperature Dispersion is all in the aspect that is unfavorable for the growth of corn, causes the shortcomings such as this planting method yield is lower, grain quality is poor. Increasing the planting density of corn will cause problems such as poor ventilation and light transmission, and lack of wind resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for planting corn with lodging resistance and well-developed root system, so as to increase the yield of corn.
