Abstract

The invention relates to the technical field of agricultural planting, in particular to a convention-cropping and furrow-planting drought-resistant cultivation method for spring soybeans. The convention-cropping and furrow-planting drought-resistant cultivation method comprises the following steps that (1) an organic fertilizer is applied after autumn harvest, deep ploughing is conducted, winter irrigation is conducted in early November, and raking, leveling and soil moisture preserving are conducted in early February in the next year; (2) coating treatment is conducted on soybean seeds, and then sowing is conducted; (3) intertillage is conducted when the soybeans grow to a compound leaf period, a leaf fertilizer is topdressed in the early flowering period and the seed filling period of the soybeans, and irrigation is conducted in the seed filling period of the soybeans. The technical problems that drought in spring restricts soybean growth and development, soil moisture content of main soybean producing areas in Ningxia is poor, and consequently soybean germination and seedling emergence are affected and the like are solved, and the yield of soybeans can be remarkably increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a drought-resistant cultivation method for spring soybeans grown in furrows. Background technique [0002] Soybean (scientific name: Glycine max (Linn.) Merr.) is an annual herb of the family Fabaceae, 30-90 cm high. Native to China, it is cultivated all over China and is also widely cultivated all over the world. Soybean is one of the important food crops in China. It has been cultivated for 5,000 years. It was called Shu in ancient times. It is mainly produced in Northeast China. It is a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. [0003] During the growth and development of soybean, it is affected by many factors, and drought is one of the important factors affecting the growth and development of soybean. Ningxia Yellow River Irrigation Distr...
