Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below, obviously, the described embodiments are only some of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] A method for cultivating soybeans in dry land covered with plastic film in hole-sowing winter wheat, comprising the following steps:

[0023] S1: The first batch of winter wheat cultivation:

[0024] The first batch of winter wheat is planted with full-film-covered soil hole-sowing. After covering the film, spread a layer of fine cotton soil with a thickness of about 1cm on the film surface, and then directly sow winter wheat with a plastic-film wheat hole-seeder or a hand-push wheel-type hole-seeder; Before planting ...

Abstract

The invention discloses a cultivation method for dry land full-film earthing hole sowing winter wheat later-crop replanted soybeans, and belongs to the technical field of cultivation of winter wheat later-crop replanted soybeans. The cultivation method comprises the steps of carrying out fertilizer application, deep tillage, rotary tillage, rake grinding and full-ground plastic film mulching on afirst crop of winter wheat according to technical regulations of full-film earthing hole sowing cultivation, and then carrying out hole sowing of the winter wheat in good time; after mechanically harvesting the winter wheat in a summer, remaining plastic films, wherein the stubble height is 2-3 cm; removing wheat straws; sealing damaged positions of the plastic films in time; and directly carryingout hole sowing of soybeans without tillage, wherein in a whole period of duration of the second crops, the plastic films are not removed until the second crop of soybeans are harvested. By the technology, after the first crop of winter wheat is harvested, procedures such as soil ploughing, rake grinding, rotary tillage before sowing and film mulching are omitted, the plastic film utilization efficiency is improved, mechanical loss and plastic film 'white pollution' are reduced, and purposes of saving costs, improving efficiency and implementing green cultivation are realized.

Description

technical field [0001] The invention discloses a method for cultivating soybeans in dry land covered with film and hole-sowing winter wheat for multiple cropping, in particular to the technical field of soybean cultivation for winter wheat and multiple cropping. Background technique [0002] Soybean is one of the four major cultivated crops in my country. It is the most important oil crop and grain-forage crop in the world. It is also an important high-quality oil crop in the northern dryland area. Most soybeans are planted in rain-fed agricultural areas with an annual rainfall of 300-600 mm. Due to long-term drought stress and extensive cultivation methods, soybean yields are low and unstable. Hole sowing technology with full film covering soil is a new high-efficiency dry farming agricultural technology that uses film surface to sow seed holes to collect rain, fully cover the ground to inhibit soil water evaporation, and make full use of light and heat resources. It can ef...
