Device with functions of seedling protection and straw anti-burning and decay promotion for no-tillage planter

Abstract

The invention relates to a device with functions of seedling protection and straw anti-burning and decay promotion for a no-tillage planter. The device comprises a frame, wherein a seeding tube and a furrow opener are sequentially arranged on the frame along the forward direction of the no-tillage planter, and a straw decay promotion device moving synchronously with the furrow opener is also arranged on the frame. The invention provides the device with the functions of seedling protection and straw anti-burning and decay promotion for the no-tillage planter.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a no-tillage seeder, in particular to a device for the no-tillage seeder with the functions of protecting seedlings and preventing straw from burning and promoting decay. Background technique [0002] The characteristic of no-tillage sowing is that ≥70% of stubble or straw (hereinafter referred to as stubble) is left on the surface of the soil, and the area of ​​the ground surface cannot be greater than 30%. Present no-tillage seeding machinery does not carry out any processing to the stubble stalk when it is working, but ditches, fertilizes, and sows at the side of the stubble stalk or at the place facing the stubble stalk. Like this, the stubble stalk that has not been shredded is pressed in the soil by ditch opener, and the stubble stalk of larger part still stands upright on the ground surface. [0003] If seeds are sown on stubble stalks that are not crushed and pressed i...

Problems solved by technology

[0003] If the seeds are sown on the stubble that has not been chopped and pressed into the soil, it will directly affect the emergence rate of the seeds, and the seedlings are prone to dieback during the growth period

For the larger part of the stubble that is still upright on the ground, if the height of the stubble is more than 30cm, the farmers will burn it to ensure that the seedlings can fully contact with the sun after they grow up, and burning will affect the germination of the seeds and the growth of the seedlings; if they are not burned, After the seedlings are unearthed, the still upright stubble stems cover the sunlight and hinder the ventilation, so that the seedlings cannot grow vigorously. What is more serious is that the flakes of stubble stems stand upright and are not easy to rot. After drying, they are easy to burn and burn the seedlings to death. , which not only reduces crop yield, pollutes the environment, but also cannot achieve the goals of no-tillage sowing, rotting stubble returning to the field, increasing soil organic matter, and reducing soil erosion and sandstorms

Especially in areas where there are two crops a year, if the stubble rots for too long, it will directly affect the cultivation effect of the second season.
