Abstract

The invention discloses a reasonable-plough plough layer ploughing method compatible with tightness of tight seedling belt and loosened line spacing, which belongs to the technical field of agricultural planting and is completed by adopting steps of seedling belt repression and line-spacing deep scarification during an elongation stage. A seedling belt in the current year can be repressed after corns are planted in spring, and the compacting degree of repressed soil is 1.26-1.28 g / cm<3> in volume weight; and deep scarification is carried out during the elongation stage of the corns. According to the reasonable-plough plough layer ploughing method disclosed by the invention, the plough layer construction compatible with the tightness of tight seedling belt and loosened line spacing is realized through a method of comprehensive deep scarification and local repression of the seedling belt, and a compact, wet, ventilative and good condition is created; the contradictions between ventilating and lodging prevention, fertilizer supply and fertilizer absorption, water permeability and humidity raising and the like of a plough layer can be solved; the contradiction between straw mulching and seedling protecting can be solved, and labor-saving farming can be realized.

Description

technical field

[0001] The invention belongs to the technical field of agricultural planting and relates to a corn cultivation method. Background technique

[0002] The Northeast Plain is one of the three major black soil regions in the world. The rain and heat in this area are in the same season, and the soil is fertile. It is an important commodity grain base in my country. The food crops are mainly corn, soybean and rice. The corn planting area in this area accounts for more than 70% of the province's main crop planting area, and the grain yield per unit area, per capita share and commodity rate all rank first in the country. It is the famous "Golden Corn Belt". The grain production in this region occupies a pivotal position in my country and has made important contributions to ensuring national food security.

[0003] In recent years, due to extensive production methods, over-management of land, excessive pursuit of high output of agricultural products at the expense ...
