Problems solved by technology

The traditional corn planting method is generally a single plant in one hole, with equal row spacing. Since the leaves of the corn plant are wide and long, if the planting is too dense, the leaves will block each other, affecting the lighting rate, resulting in a reduction in crop yield; It is also not conducive to high yield; in the traditional corn planting process, the deep structure characteristics of the soil are not paid attention to, the air permeability and water and fertilizer retention capacity of the planting land are poor, and the limited fertilizer cannot be efficiently supplied to the corn plants; in addition, in order to increase the yield, Traditional planting usually uses large-dose, high-frequency spraying of pesticides to eliminate and control pests and weeds on corn. This planting method can reduce the occurrence of pests in the short term, but in the long run, it is not conducive to the growth of plants. and increase in production

Embodiment 1

[0018] (1) Scientific land preparation: after the harvest of the previous stubble, remove the weeds, residual plants and dead branches and leaves in the field, and spread 50kg of poisonous soil, 0.5kg of chopped wheat straw with a length of 2 to 5cm, 5kg of bactericidal and herbicidal fertilizer and base fertilizer (including 3000kg of decomposed farmyard manure, 30kg of urea and 20kg of potassium dihydrogen phosphate), then plow the field 25-30cm deep, and bury the above poisonous soil, chopped straw, bactericidal and herbicidal fertilizer and base fertilizer into the soil In the process, raking and grinding the surface soil, digging out the field ridges in the field after raking according to the east-west direction, the distance between adjacent field ridges is 70cm, and each field ridge is 40cm wide; wherein, the poisonous soil is 1.5kg30% octyl sulfur Phosphorus emulsion and 30kg field soil are mixed evenly, and the bactericidal herbicide fertilizer is decomposed neem bark,...

Embodiment 2

[0024] (1) Soil preparation: After the previous stubble is harvested, remove the weeds, residual plants and dead branches and leaves in the field, and sprinkle 100kg of poisonous soil, 1.0kg of chopped wheat straw with a length of 2 to 5cm, and 3kg of Bactericidal herbicide fertilizer and base fertilizer (including 4000kg decomposed farmyard manure, 50kg urea and 15kg potassium dihydrogen phosphate), then plow the field 25-30cm deep, and bury the above poisonous soil, chopped straw, bactericide herbicide fertilizer and base fertilizer into the soil , raking and grinding the surface soil, digging out the field ridges in the field after raking according to the east-west direction, the distance between adjacent field ridges is 90cm, and each field ridge is 50cm wide; wherein, the poisonous soil is 1.5kg30% phoxim Emulsion and 30kg field soil mixed evenly, the bactericidal herbicide fertilizer is decomposed neem bark, Daphne chamaejasma, Galla gall, Sapindus seed coat, mushroom sla...

Abstract

The invention discloses a high-yield pollution-free cultivation method for corns. The high-yield pollution-free cultivation method comprises the following steps: (1) scientific land preparation; (2) seed selection and treatment; (3) reasonable planting; (4) field management; (5) timely harvesting. According to the high-yield pollution-free cultivation method for corns, by reasonable land preparation, seed selection, species planting layout design and scientific pest damage prevention and treatment, the light interception rate of a corn plant is increased, the morbidity caused by diseases and insect pests is reduced, the harvested corns are high in yield, seeds are full, and the contents of pesticides and chemical fertilizers are small; the harvested corns have the characteristics of high yield, no pollution and suitability for large-range planting and popularization.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield and pollution-free cultivation method for corn. Background technique [0002] Corn is one of the important food crops in my country. The traditional corn planting method is generally a single plant in one hole, with equal row spacing. Since the leaves of the corn plant are wide and long, if the planting is too dense, the leaves will block each other, affecting the lighting rate, resulting in a reduction in crop yield; It is also not conducive to high yield; in the traditional corn planting process, the deep structure characteristics of the soil are not paid attention to, the air permeability and water and fertilizer retention capacity of the planting land are poor, and the limited fertilizer cannot be efficiently supplied to the corn plants; in addition, in order to increase the yield, Traditional planting usually uses large-dose, high-frequency spraying of...
