Earth-covering drought-resisting seedling-protection farming method for planting soybeans after crop of spring corn stubbles

Abstract

The invention discloses an earth-covering drought-resisting seedling-protection farming method for planting soybeans after a crop of spring corn stubbles. The farming method comprises the following steps: (A), stubble cleaning: cleaning spring corn stubbles, reserving a close-end border surface with the width of 120 cm and a furrow with the width of 40 cm, and shallowly rotationally farming or manually cleaning the stubbles in the depth of 5-6 cm; (B), ditching: transversely cutting the close-end border surface to form seeding furrows with the depth of about 5 cm and the line spacing of 30 cm; (C), watering: irrigating sufficient water to the interiors of the seeding furrows; (D), seeding: planting soybean seeds immediately after watering; (E), seed covering: immediately covering the soybean seeds with fine earth when no visible water exists in the seeding furrows, wherein the thickness of the fine earth covering the soybean seeds is about 3 cm; (F), earth covering: covering the soybean seeds with the fine earth till no wet earth can be seen on the seeding furrows of the close-end border surface, wherein the thickness of the fine earth covering the soybean seeds is 3-4 cm; (G), seedling protecting: preventing insects, hares and wild pigeons from damaging tender seedlings before and after soybean seedlings grow up; (H), moisturizing: in principle, covering the close-end border surface with the fine earth once in every five days after seeding, and timely covering the close-end border surface with the fine earth when soil is workable after raining so as to reduce the evaporation of water; (I), managing: performing daily field management.

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 spring corn stubble in hilly and mountainous areas and plain dry lands 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 im...

Problems solved by technology

However, the economic benefit of planting soybeans in paddy fields is not as high as that of planting rice, so farmers are not very motivated, and it is also inconsistent with the tradition of producing rice in paddy fields.
