Problems solved by technology

[0003] Due to the lack of unified standards for the planting management of peanuts in the Northeast production area, the peanut production in the Northeast production area is unstable, sometimes high and sometimes low
In many places, the growth period of peanuts is not suitable, and rotten seeds appear when sowing; frost damage occurs when harvesting

Abstract

The invention discloses a high-yield cultivation method for peanuts in the northeast region, and belongs to the technical field of high-yield cultivation of peanuts. According to the method, a large-ridge double-row cultivation mode is adopted for peanut planting in the northeast region, black plastic film covering is adopted in the planting process, and a microbial fertilizer additive is added during fertilization. According to the planting method, the peanut yield is remarkably increased, high-yield cultivation of peanuts in the northeast region can be achieved, and high economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of high-yield cultivation of peanuts, and in particular relates to a method for high-yield cultivation of peanuts in Northeast China. Background technique [0002] Peanut occupies an important position in the world's grain, oil and food. In recent years, with the adjustment of the country's planting structure, the peanut planting area has developed rapidly. In 2019, the national peanut sowing area was 4.65 million hectares, and the total peanut production reached 17.52 million tons. Aflatoxin pollution seriously threatens the safety of peanut production and consumption, and is also the most important risk factor that needs to be addressed for peanut export. Peanuts produced in Northeast production areas (Liaoning, Jilin, Heilongjiang, Inner Mongolia, etc.) are famous for having no or very little aflatoxin pollution. They are favored by domestic and foreign peanut companies and are the export base of high-qu...
