Corn planting method

Abstract

The invention discloses a corn planting method. The method has the advantages that processed corn straw is returned to the field, waste resources can be sufficiently utilized, fertilizer use amount isreduced, the straw is crushed during the field returning to facilitate the fermentation of the straw, and other fertilizer is applied to serve as the base fertilizer, and field fertility can be increased effectively; during sowing, line spacing is reasonably controlled, field waste caused by excessively large line spacing, excessively small line spacing is avoided, and corn yield is increased; during planting, topdressing is performed reasonably, pesticides are applied to control diseases and pests, weeding is performed to resist lodging, and yield increasing is guaranteed; the seed selectionstep, the soil preparation step, the fertilizing step and the pesticide applying step of the method are obtained on the basis of existing experience and the researches of the inventor, various natural conditions are fully utilized, seeds, the fertilizer, pesticides and the like are strictly controlled, an evident yield increasing effect is achieved, and agricultural production efficiency can be increased.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting corn. Background technique [0002] my country is a large developing agricultural country with a population of 1.3 billion. Agriculture in China has always been regarded as a strategic industry that secures the world and stabilizes the hearts of the people. my country's agricultural practitioners have repeatedly created miracles, feeding nearly 21% of the world's population with less than 9% of the world's arable land. The success of hybrid rice has not only solved the food problem for hundreds of millions of people, but also guaranteed my country's food security. [0003] Corn is the crop with the highest total output in the world, and its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high...

Problems solved by technology

But today's soil fertility, farming system, crop varieties, cultivation techniques, and fertilization methods have all undergone great changes, and the original planting methods can no longer guide the current agricultural production.

[0008] For example, in terms of fertilization habits, in order to obtain higher yields, farmers use excessive or unreasonable fertilizers, often focusing on partial application of nitrogen fertilizers, while ignoring the promotion effect of combined application of phosphorus and potassium fertilizers on corn growth and development, yield composition and nutrient absorption. As a result, the yield of corn is not high, the utilization rate of fertilizer is very low, and the economic potential of planting corn cannot be fully utilized. What is more worrying is the pollution to the environment and the potential harm to human and animal health.
