Corn planting method

Abstract

The invention discloses a corn planting method. The method comprises the steps that sandy loam field pieces which are loose in soil, deep in soil layer and good in drainage within the altitude ranges of 1600 m to 2500 m are selected; soil preparation and base fertilizer applying are carried out, and airing and seed soaking are carried out before sowing, wherein an adopted seed soaking agent is prepared from 5-15 parts of methidathion, 10-20 parts of organic solvent, 3-12 parts of penetrant, 0.5-6 parts of validamycin, 0.5-6 parts of rubican and 0.5-4 parts of heteroauxin; after sowing, field management is carried out, and harvesting is carried out after maturing; a compound fertilizer is dressed when 7-11 leaves grow on each corn seedling, wherein the compound fertilizer comprises pig manure, biogas slurry, fulvic acid, coal ash, seaweed, peat, realgar, mono potassium phosphate, carbamide, calcium magnesium phosphate and lime powder. Corn is promoted to grow and absorb needed nutrients, stress resistance is improved, the high yield and income increase are promoted, meanwhile, the content of microelements is increased, nutrient balance and corn absorption are promoted, and the method is extremely suitable for planting in Dali and other high-altitude regions.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a corn planting method. Background technique [0002] Maize belongs to the family of Poaceae Maize. Maize is a species of maize. With the development of the world's navigation industry, corn has gradually spread to all parts of the world and has become one of the most important food crops. Corn is known as a longevity food and is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides. It has great potential to develop food with high nutrition and high biological function.

Farmers generally do not have scientific planting methods, and are blind and random; especially fertilization, most farmers use traditional methods to blindly fertilize corn, which not only wastes a lot of resources and pollutes the environment, but more importantly, the utilization rate of chemical fertilizers increases with the amount. At the same time, it leads to the crazy growth of corn technical leaves and even the outbreak of diseases and insect pests, and the phenomenon of lodging is common. Combining various factors, the production cost of corn continues to rise, but the yield cannot be improved, and the quality is gradually declining.
