Planting method of continuous cropped soybean

Abstract

The invention discloses a planting method of continuous cropped soybean, comprising the following steps: in deep winter, conducting fertilization and deep ploughing on a planting land and spraying a biogas slurry; in early spring, applying a base fertilizer, preparing the land, and directly sowing soybean seeds after seed dressing; and determining plant rows and preventing pests and diseases. Themethod of the invention is simple and practical, is suitable for hardening soil of a planting land for continuous cropped soybean, can change acidic soil, employs decomposed poultry manure to enable soil to foam and maturate, and at the same time, kills bacterial sources and eggs of pests and diseases by conducting deep ploughing and applying the biogas slurry in winter. Additionally, a drug for preventing underground pests of soybean employs a modified seed dressing agent with extremely strong toxicity and long-lasting drug properties and is capable of preventing underground pest from bitingseeds and eating seedling roots.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for planting continuous soybeans. Background technique [0002] Soybean Fabaceae soybean is an annual herb, 30-90 cm high. The stem is stout, erect, densely covered with brown long bristles. Leaves usually have 3 leaflets; stipules are veined and yellow pilose; petiole is 2-20 cm long; leaflets are broadly ovate and papery; racemes are short and few-flowered, long and multi-flowered; total pedicel usually has 5 -8 sessile, tightly packed flowers; bracts lanceolate, strigillose; bracteoles lanceolate, appressed setae; calyx lanceolate, flowers purple, lilac or white, base petalized Stem, petals castrate. The pods are hypertrophic, slightly curved, drooping, yellow-green, densely covered with brown-yellow long hairs; 2-5 seeds, oval, nearly spherical, with smooth testa, various in light green, yellow, brown and black. The flowering period is f...

Problems solved by technology

[0003] There are many types of underground pests in the planting area of ​​continuous crop soybeans, mainly grubs, mole crickets, needleworms and cutworms, etc., especially grubs, which not only seriously affect the yield and quality of soybeans, but also accumulate with successive years of planting. , the hazards are increasing year by year, and the traditional chemical control can no longer meet the needs of life; at the same time, the continuous stubble also causes serious nutritional imbalances in the planted soil, and serious hardening
