Buckwheat deep and shallow row sowing machine and sowing weed prevention method thereof

Abstract

The invention discloses a buckwheat deep and shallow row seeder which comprises a rack, a traction rod, a supporting wheel, a transmission shaft, a press wheel, a shallow row seeder assembly and a deep row seeder assembly, the bottom of the deep row seeder assembly is connected with a deep row seed pipe, the bottom of the deep row seed pipe is connected with a deep row furrow opener, and the bottom of the shallow row seeder assembly is connected with a shallow row seed pipe. The bottom of the shallow-row seed pipe is connected with a shallow-row furrow opener, a furrow plough is arranged on the upper middle portion of the front portion of the deep-row furrow opener, the two sides of the rear portion of the deep-row furrow opener are connected with a left herringbone ridge pressing device and a right herringbone ridge pressing device through depth regulators, the front portions of the herringbone ridge pressing devices are high, and the rear portions of the herringbone ridge pressing devices are low. After the seeder is used for seeding, buckwheat can be sown in time, seed ditches formed by deep rows are beneficial to water storage and soil moisture conservation, the height difference and density adjustment of the deep rows and shallow rows in the seedling stage utilize the three-dimensional space advantage, light transmission is achieved, full and strong seedlings are guaranteed, the density advantage of the three rows in the later stage forms the ridge sealing advantage, field weed growth is suppressed, and the yield is increased. Intertillage operation is omitted.

Description

Technical field [0001] The present invention relates to the field of agricultural planting, which involves a buckwheat deep-sized seedling machine and its sowing anti-grass method. Background technique [0002] Buckwheat is a traditional crash crowd, and the buckwheat property is a mountain moisture, salt base, and uncomfortable area, and is also a region where the poor is distributed. Buckwheat is often sowing, and there is no normal sowing, and the weeds of buckwheat fields are the main problems faced by buckwheat planting. Buckwheat is generally raining after raining, often restricted by drought conditions, missed the best sowing time, causing harvest season buckwheat to be normal maturity, production decline, severe miscarriage, or even cause non-increasing particles. The traditional buckwheat planting mode mainly has two ways of broadcasting and spreading, and the production technology is sufficient, and there is a good condition. The late stage shows the neutrality, solves ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing buckwheat sowing technology cannot sow due to insufficient rain at the sowing time, and there are too many weeds in the ridges in the later stage, and provides a buckwheat deep and shallow row seeder and its sowing weed control method
