Problems solved by technology

Most people think that the yield of corn has reached the maximum yield, and many people even blindly adopt the method of applying more fertilizers, but the yield has hardly increased, and it has caused damage to the soil
[0003] The traditional corn planting is single plant in one hole, with equal row spacing. This planting method has poor plant permeability, and the root growth of crops, lodging resistance, corn pollination opportunities, surface water evaporation rate and night temperature distribution are all unfavorable for corn. In terms of growth, this planting method has disadvantages such as low yield and poor grain quality, and it is not conducive to field management and harvest. At the same time, it will also lead to low yield of corn

Abstract

The invention relates to a corn growing and cultivation method comprising specific steps of field preparation, seed selection, sowing, fertilization, water delivery, and field management. Sowing, pipe laying, mulching and soil covering are completed with an air-suction precision seeder. A sowing hole space is 35-45cm, and one seed is sowed in one hole. After sowing, a water delivery pipe is connected, and seedling water is delivered, wherein 16-30m<3> of water is delivered to every 500m<2> of field. The fertilizer is applied with water during the water delivery process. In the field management step, with the water delivery pipe, soil water content is maintained at 70-85% of a maximal field water capacity, and fertilizer is delivered during water delivery. According to the method, a narrow row is arranged between every two rows, such that a plant border row dominance is artificially created, light transmittance between corn plants is increased, and photosynthetic efficiency is improved. The method facilitates corn plant top dressing, water delivery and harvesting, and facilitates nutrient balanced application and absorption. Wind stress on the plants is reduced, and corn yield is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a corn planting and cultivation method. Background technique [0002] Corn is the main dry field crop in northern my country, and its planting method and yield are of great significance to the national economy and people's livelihood. Over the years, most areas still adopt the traditional ridge planting method, which seriously restricts the yield of corn and the income of farmers. Most people think that the yield of corn has reached the maximum yield, and many people even blindly adopt the method of applying more fertilizers, but the yield is hardly increased, and the soil is damaged instead. [0003] The traditional corn planting is single plant in one hole, with equal row spacing. This planting method has poor plant permeability, and the root growth of crops, lodging resistance, corn pollination opportunities, surface water evaporation rate and night temperature distr...
