Abstract

The invention relates to a grain crop cultivation technology, in particular to a corn planting method. Soil preparation and deep ploughing are carried out, full and brightly colored corn seeds are carefully chosen to be sowed, the width of sowing lines is 95 cm, every five holes fall into a planting set, the set interval is 45 cm, the hole distance of each planting set is 5 m, and each hole is provided with two seedlings; every six planting lines fall into a planting unit, the planting lines of each planting unit are arranged in a staggered mode, and the first planting sets of each line are arranged in a staggered mode with the distance between the first planting lines and planting lines gradually increasing by 6cm; in the fruiting period, a proper amount of fertilizer is applied to each mu of land. The arrangement mode that the holes in each planting set are connected in series by a short distance is adopted for planting, the line interval is wide, and the distance between the sets is large, so that nutrient is evenly applied and absorbed by corns; the root systems of plants are crossed for supporting, inter-plant ventilation is achieved, pressure on plants from wind is weakened, wind can pass through space between the sets, and lodging is effectively avoided; corns have many strong roots due to potential competition, so that nutrient absorption is facilitated; the utilization rate of chemical fertilizer is improved.

Description

A kind of corn planting method

Technical field

The present invention relates to a kind of plant cultivation grain technology, especially a kind of corn planting method.

Background technology

Traditional corn planting method is a cave individual plant planting type, owing to limiting by multiple condition, general 4200 ~ 4700 plants/acre, therefore, the root growth of crop, lodging tolerance, corn pollination chance, evaporation from topsoil speed and nocturnal temperature distribute all to be in and are unfavorable for corn growth aspect, cause this implantation methods output lower, the shortcomings such as grain quality difference.Increase the planting density of corn, can cause again that ventilation and penetrating light is poor, the not problem such as wind resistance.In addition farming technique falls behind, and site preparation quality is poor, and sowing level is low, Miao Buquan, does not strengthen, and density is not suitable for, and makes corn yield minimizing 5 ~ 8%.

Summary of the invention

The problem that the present invention causes corn yield low in order to solve traditional corn planting method because poor, the anti-fall performance of plant permeability is weak, proposes a kind of corn planting method of high yield.

For solving the problems of the technologies described above, the present invention includes following steps:

Wholely: deep ploughing 30cm, every mu of ground applies phosphate fertilizer 10kg, potash fertilizer 5kg;

Seed selection: selected full seed, the corn seed of bright color;

Sowing: the line width 95cm sowing row, often in sowing row, 5 caves are one kind and plant group, group distance 45cm, in often plantation group, and cave distance, 5m, the two strain in single cave; Every 6 sowing behaviors planter units; Sowing row incorrect order arrangement in every planter units; In every planter units, often first kind of the row pattern incorrect order arrangement of planting group distance plantation line and increasing progressively with 6cm;

Fertilising: during result, every mu of ground applies nitrogenous fertilizer 10kg, humic plant ash 5kg, chicken droppings excrement 15kg.

Owing to adopting closely bead type aligning method plantation between cave in often plantation group, and line space is wider, the spacing of group and group is larger, be conducive to nutrient equilibrium to use and Maize Absorption, often organize root system between plant to cross one another support, can ventilate between strain, weaken the pressure of wind to plant, between group, can wind be crossed, can lodge by effectively preventing; Potential competition impels corn root many to strengthen, and is conducive to Nutrient Absorption; Improve the availability of chemical fertilizer.

Embodiment

Wholely: deep ploughing 30cm, every mu of ground applies phosphate fertilizer 10kg, potash fertilizer 5kg;

Seed selection: selected full seed, the corn seed of bright color;

Sowing: the line width 95cm sowing row, often in sowing row, 5 caves are one kind and plant group, group distance 45cm, in often plantation group, and cave distance, 5m, the two strain in single cave; Every 6 sowing behaviors planter units; Sowing row incorrect order arrangement in every planter units; In every planter units, often first kind of the row pattern incorrect order arrangement of planting group distance plantation line and increasing progressively with 6cm;

Fertilising: during result, every mu of ground applies nitrogenous fertilizer 10kg, humic plant ash 5kg, chicken droppings excrement 15kg.
