Pollution-free high-yield cultivation method of summer soybeans

Abstract

The invention discloses a pollution-free high-yield cultivation method of summer soybeans. The method includes the steps that high-yield improved varieties are selected, enough base fertilizer is applied, organic fertilizer, standard phosphate fertilizer and standard nitrogen fertilizer are applied before sowing, weeds in fields are removed, and high-concentration nitrogen-phosphorus-potassium compound fertilizer is applied; the soybeans are sown during the period from the last ten-day period of May to the first ten-day period of June, wherein the sowing line spacing ranges from 28cm to 40cm, and the sowing depth ranges from 3cm to 4cm; closed weedicide is utilized to evenly spray the soybeans, strong seedlings are cultivated on the basis of full stand and even stand in the mid-to-late June, the operation of checking the seedlings and filling the gaps with the seedlings is immediately conducted after emergence of the seedlings, and the 15,000 to 18,000 seedlings are reserved per mu after thinning; two to three times of intertillage is conducted during the period from the first ten-day period of July to the middle ten-day period of July, urea dressing is conducted, watering is conducted to prevent drought, and spraying is conducted according to the insect pest situation; grain filling fertilizer is applied during the grain filling period from the early-to-mid August to the mid-to-late September; the soybeans are harvested in time during the period from the mid-to-late September to early October, and the grains are aired in time after being harvested and threshed, and the grains can be put in a storage and stored when the water content of the grains decreases to 13%. The method has the advantage that the yield per mu of the summer soybeans is more than 200 kilograms.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a pollution-free and high-yield cultivation method for summer soybeans. Background technique [0002] Planting summer soybeans in high sandy soil areas along the river, the existing cultivation techniques have low yields and cannot reach the yield target of 200 kg per mu. Now high-yield summer soybeans are cultivated and meet the standards of pollution-free agricultural products. According to the production situation of summer soybeans along the river and the After many years of experimental research, a technical index of 200 kg per mu of summer soybeans was proposed with the main content of varieties, sowing dates, population structure, yield structure, fertilizer and water supply indicators, and temperature and light resources. The operating procedures for realizing the above indicators are introduced in detail, the content is standardized and clear, and the operability ...
