Soybean cultivation method with draught resistance and seedling protection through soil coverage in field of watermelon stubble

Abstract

The invention relates to a soybean cultivation method with draught resistance and seedling protection through soil coverage in a field of watermelon stubble. The cultivation method comprises the steps of (1), stubble cleaning, wherein watermelons and stubble are cleaned in the field, a border surface of 120 cm wide and a border furrow of 40 cm wide are reserved, and a hollow rotating tillage and manual stubble cleaning of 5-6 cm deep are conducted; (2), furrow plowing, wherein a sowing furrow with a depth of about 5 cm and a row distance of 30 cm are horizontally plowed on the border surface; (3), watering, wherein the sowing furrow is watered sufficiently; (4), sowing, wherein soybean seeds are sowed right after watering; (5), covering the soybean seeds, wherein the soybean seeds are covered with fine soil as soon as no visible water is seen in the sowing furrow, and the fine soil covering the soybean seeds has a thickness of about 3 cm; (6), covering soil, wherein fine soil are used for covering the sowing furrow so that no visible wet soil is on the border surface, and the fine soil covering the soybean seeds has a thickness of 3-4 cm; (7), seedling protection, wherein tender seedlings are protected from insects, hares, wild pigeons and the like before and after soybean seedlings emerge completely; (8), moisture preservation, wherein the border surface is covered with fine soil once every 5 days in principle, and covered with fine soil in time when the soil is suitable for plowing after raining so that water evaporation is reduced; (9), managing, daily field management should be conducted well.

Description

technical field [0001] The invention relates to a farming method for soybeans covered with soil to resist drought and protect seedlings, in particular to a cultivation method for planting soybeans covered with soil for drought resistance and protected seedlings in hilly and mountainous areas and dry plains in southern my country. Background technique [0002] Soybean is a grain and oil crop, native to my country, and is one of the oldest cultivated crops. According to the local cultivation system and sowing season, it can be divided into spring soybean, summer soybean, autumn soybean and winter soybean. my country used to be the main producer and exporter of soybeans. Due to my country's large population and little arable land, the grain production area must be guaranteed, the soybean planting area has been compressed, and the supply of domestic soybeans is in short supply. Therefore, my country has changed from a soybean exporter to a soybean importer. Under the circumsta...
