Problems solved by technology

[0004] Moreover, in recent years, corn production has focused on profit and neglected land, and there is great pressure to increase yield per unit area.
In order to pursue stable and increased corn production, farmers apply more chemical fertilizers on each unit of land, and some land has already caused soil compaction; at the same time, simple fertilization methods, due to uneven quality and unscientific fertilizer ratios, aggravate the occurrence of diseases and insect pests and reduce resistance

Abstract

The invention discloses a corn cultivation method. The corn cultivation method specifically comprises the following steps: (1) variety selection: a step of selecting a proper corn variety with good quality, disease resistance, pest resistance and stress resistance in a growth period; (2) land preparation: a step of cleaning a planting area, removing weeds, stones and sundries, adjusting the pH value of soil, plowing the soil, and digging drainage ditches; (3) ditching and soil covering: a step of arranging wide rows and narrow rows at intervals, applying decomposed farmyard manure according tothe area of a land parcel, uniformly spreading the farmyard manure into furrows, covering the furrows with loam, and compacting the loam; (4) precision sowing: a step of sowing corn seeds in a double-row wide-narrow-hole double-grain mode at the inner sides of two ridges, and compacting the soil after sowing is finished; and (5) field management, which comprises field management in a seedling stage, field management in an ear stage and field management in a flower and grain stage. According to the corn cultivation method provided by the invention, a density and a distance are increased; ventilation and light transmission are achieved; moisture is preserved; soil moisture is increased; full stand is realized; the fertilizer efficiency is improved, so plant strengthening is achieved; the corn cultivation method is especially applicable to northeast regions in China; whole-process mechanization is achieved, so the purposes of labor saving, fertilizer saving, water saving and high yield are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural product planting, and more specifically relates to a method for cultivating corn. Background technique [0002] Corn is an important food crop and feed crop, and it is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Because corn is rich in protein, fat, vitamins, trace elements and cellulose, it is known as a longevity food and has great potential for developing foods with high nutrition and high biological functions. [0003] In my country, the planting distribution area is vast, and the total annual output is large. In 2013, the output of ordinary corn in my country reached 215 million tons. The Northeast region has a vast territory and is the largest main producing area of ​​corn. However, the climate conditions in the Northeast region are harsh, and the corn will catch up with the high incidence of drought du...
