Embodiment Construction

[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the embodiments of the present invention will be described clearly and completely below.

[0012] A no-tillage planting method for narrow row soybeans is realized through the following technical solutions:

[0013] (1). First, after the winter harvest of flat crop corn in the previous year, the corn stalks are directly crushed and returned to the field by corn harvesting machinery;

[0014] (2). In the next spring, without any soil tillage, use a 19cm narrow row-spacing soybean no-tillage drill to directly sow 19cm row-spacing soybean seeds on the corn stubble;

[0015] (3). The planting density is 550,000 plants / ha, and the varieties are semi-dwarf and lodging resistant varieties;

[0016] (4). Apply chemical weed control technology before and after planting to control weeds in the field, apply field traffic control tech...

Abstract

The invention discloses a no-tillage planting method of narrow-row soybeans. The method is implemented by virtue of the following technical scheme: (1) firstly, after winter harvest of conventional flat planting corns in the last year, directly crushing corn straws by virtue of corn harvesting machinery; (2) under the condition that any soil tillage is not carried out in the winter of the next year, directly sowing soybean seeds on corn stubbles at a row pitch of 19 cm by using a 19 cm narrow-row-pitch soybean no-tillage drill planter; (3) sowing at a sowing density of 550000 plants / hectare, and selecting a semi-dwarf lodging-resistant variety; (4) controlling and eliminating field weeds by applying a chemical weeding technology before and after sowing, managing the travelling path of the machinery in fields by applying a field traffic control technology, and preventing soil from being compacted at the same time; and (5) controlling soybean diseases and insect pests by adopting a comprehensive prevention and control technology during breeding. According to the method disclosed by the invention, no-tillage and returning straw mulching technologies are used for protecting soil, reducing soil erosion, improving the field fertility, avoiding straw burning in the field from polluting the environment, and increasing and reducing C emission.

Description

Technical field [0001] The invention relates to the technical field of soybean planting, and specifically relates to a no-tillage planting method of narrow row soybeans. Background technique [0002] Heilongjiang Province has a high latitude, limited heat resources, and low soybean yield. Conventional 65-70cm row spacing ridge cultivation is wide, and the sealing period is late. The light energy utilization efficiency is low and the soybean yield level is low. At the same time, it is difficult to return straw to the field by conventional ploughing. And increase soil C emissions and decrease soil fertility. Summary of the invention [0003] The purpose of the present invention is to provide a no-tillage planting method for narrow row soybeans, which can effectively solve the problems existing in the background technology. [0004] A no-tillage planting method of narrow row soybeans is realized through the following technical solutions: [0005] (1). First, after the winter harvest of...
