A kind of implantation methods of early soybean

Technical field

The present invention relates to agricultural plantation technology field, particularly a kind of implantation methods of early soybean.

Background technology

Soybean belongs to Papilionaceae, Glycine.Alias soya bean.Once soybean is referred to as bean on many ancient book in China,《The Book of Songs》In just have：The record of " in original bean, the common people adopt it "；Western Jin Dynasty Du is pre- to be annotated to bean word：" bean, soybean "；Qin Han just replaces bean word with beans word later.Soybean originates in China, it is estimated that, the history of China's plantation soybean for many years.The history of European and American countries the cultivated soybean is very short, is sent from China, at present, soybean culture various countries all over the world.

Soybean has become the source of most important vegetable protein and edible vegetable oil in the world today, is formed in world cereal crops and occupies critical role in international oil crops.

The planting patterns of soybean is directly connected to its group size, and group size is then an important factor for determining yield per unit area, the general principle of soybean high-yield cultivation is on the basis of reasonable utilization and reform of nature condition, with the cultivation technique measure of science, to create the well-grown light of soybean, temperature, heat, fertile condition, the yield and qualitative genetics potentiality for making soybean varieties are not fully exerted, and reach high yield, high-quality, efficient purpose.Natural conditions are usually uncontrollable, can only be deacclimatized by rational method；Implantation methods are controllable, its essence is the influences of the ecological factor to soybean physiology process and growing process such as light, temperature, heat, fertilizer are improved, so as to improve the yield of soybean and quality.

Soybean presses the difference of its sowing season, can be divided into early soybean, summer soybean, autumn soybean and the class of winter soybean four, but occupy the majority with early soybean.Early soybean is typically sowing the seed in spring, October harvest.But existing early soybean is not planted according to its Seasonal Characteristics.

The content of the invention

The technical problems to be solved by the invention are to provide according to seasonal characteristic to plant the method for early soybean, so that early soybean can better adapt to environment and utilize environmental condition, and obtain and preferably grow up, improve the yield and quality of soybean.
