Wheat wide seedlings ridge band-shaped sowing machine

Abstract

The invention provides a wheat wide seedlings ridge band-shaped sowing machine which comprises a seed box, a plurality of press wheels, a plurality of seed sowing pipelines, a plurality of ditchers and ditcher modules for enabling the seeds to be distributed in the shape of a band such as a wide seedlings ridge, wherein each ditcher module comprises at least two of ditchers for evenly sowing in the wide seedlings ridge, the press wheels are respectively arranged at the back of each ditcher module, the width of each press wheel is larger than or equal to that of each ditcher module, the width of each ditcher module is equal to that of each wide seedlings ridge, and the width between every two adjoining ditcher modules is equal to the line spacing between every two adjoining wide seedlings ridges; and in the same ditcher module, along the width direction, the adjoining ditchers are separated from one another at a certain distance, and along the front direction and the back direction, the adjoining ditchers are further separated from one another at a certain distance. The crops planted by the sowing machine can improve the ventilated and photo-permeable conditions in group canopies, and is good for the growth and development and the yield increase of the wheat.

Description

technical field [0001] The invention relates to an agricultural machinery seeder, in particular to a wheat wide seedling ridge strip seeder. Background technique [0002] Wheat is one of the three major food crops in the world. The planting area in China has been stable at more than 20 million hectares for many years. It is also the most important food crop planted in the Huanghuai-Hai Plain in China. The formation of wheat yield depends on the coordination of individual and group. The construction and formation of an excellent population structure is conducive to ventilation and light transmission in the population canopy, robust individual development, disease resistance and fall prevention, and is the basis for the formation of wheat yield. The traditional planting method in wheat production is mainly drill sowing. Increasing or decreasing the sowing amount and changing the row spacing during sowing are one of the main measures to artificially regulate the wheat populati...

AI Technical Summary

Problems solved by technology

[0007] The present invention revolves around the formation of a coordinated relationship between individual growth and group production, and aims at the problems of cumbersome sowing operations and poor group structure that affect the ventilation and light transmission in the canopy, resulting in low yields in the current wheat planting production. The present invention can be used to implement a wide range of Ridge-shaped seedling planting method combines the advantages of conventional drill sowing, sowing without ridge and ridge farming, while avoiding its disadvantages, which can promote the optimization of wheat population structure, improve the ventilation and light transmission conditions in the population canopy, and benefit the growth and development of wheat populations , increase production, improve resource utilization efficiency
