A kind of soybean cultivation method

Abstract

The invention discloses a soybean cultivation method, and belongs to the technical field of agricultural crop cultivation. The soybean cultivation method comprises the following steps of variety selection, wherein a short stalk variety is selected; field preparation and sowing, wherein after a field is flattened, ridging is conducted, and base fertilizers are applied, and when the temperature of topsoil reaches 8-12 DEG C, sowing is carried out; field management, wherein the field management comprises intertillage weeding and pest and disease control; harvest, wherein after leaves fall off completely and when soybeans become round, the soybeans can be harvested. According to the soybean cultivation method, through synchronization of a density increase and a fertilizer increase, utilization ratios of light heat, water, fertilizers and land resources can be increased, and thus a great yield increase is achieved; in addition, the soybean cultivation method is suitable for large-scale and standardized cultivation, convenient to manage, suitable for mechanized operation, convenient to use and efficient.

Description

technical field

[0001] The invention belongs to the technical field of agricultural crop cultivation, and in particular relates to a soybean cultivation method. Background technique

[0002] Soybean is an annual herbaceous plant belonging to the leguminous family. It is not only a protein crop, but also an oil crop. Soybeans can be processed into a variety of non-staple foods. The nutritional value of soybeans is very high. Soybean protein is one of the main sources of protein needed by the people of our country, and contains 8 kinds of amino acids necessary for the human body. Modern medical research shows that soybean oil does not contain cholesterol, and eating soybean oil can prevent vascular arteriosclerosis. Soybean is an important food industry raw material, which can be processed into soybean powder, baked food, children's food, health food, seasoning food, meat-filled food, etc. Soybean rhizobia can fix free nitrogen in the air, and proper arrangements for planti...

Examples

Embodiment 1

[0061] (1) Variety selection: select short stems and densely planted varieties;

[0062] (2) Soil preparation and fertilization: Intensive plowing and fine harrowing to make the ground flat and free of straw debris, then ridging, and applying base fertilizer at the same time, the amount of base fertilizer applied is 580kg / ha.

[0063] (3) Sowing: Sowing was carried out on May 7 when the surface soil temperature reached 8°C.

[0064] Planting method: as figure 1 As shown, 2 seedling strips are planted in a large ridge of 1 meter, and 1 seedling strip has 2 seedling rows; the distance between 2 seedling rows in 1 seedling strip (that is, the small row spacing in the ridge) is 5cm, and 2 seedling strips in 1 ridge The spacing (i.e. the large row spacing in the ridge) is 30cm, which realizes the purpose of densification in the ridge, and there are one-third more plants than the conventional ridge cultivation; , It is more conducive to the ventilation and light transmission betwe...
