Ditcher for alfalfa seeder and ditching and fertilizing method

Abstract

The invention discloses a ditcher for an alfalfa seeder and a ditching and fertilizing method. The ditcher is mainly composed of a ditching device, a ditcher frame, a fertilizer guiding device and a seed guiding device. The ditching device is mainly composed of side wing shovels, a sliding knife and a ditch expanding plate, and is designed to dig a high-quality seed ditch suitable for the germination of alfalfa seeds; the fertilizer guiding device is composed of a fertilizer guiding tube and a fertilizer spreading device and is used for guiding a fertilizer to the side face of the seed groove;the seed guiding device is mainly composed of a seed guiding tube and is used for introducing the alfalfa seeds into the seed ditch formed by the ditching device. The ditching and fertilizing methodmainly comprises the step of digging the inverted T-shaped seed ditch suitable for the germination of the seeds through the combination of the sliding knife and the side wing shovels; side-deep-position fertilization is achieved through the fertilizer spreading device. The requirements of alfalfa seeding and ditching can be met, the high-quality seed ditch can be dug, and the seedling emergence ofalfalfa seeds and greening in the second year are facilitated. The ditcher for the alfalfa seeder and the ditching and fertilizing method are applicable to alfalfa seeding in most areas, especially in cold and arid regions.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a ditch opener for an alfalfa seeder and a ditch fertilization method. Background technique [0002] As we all know, alfalfa is known as the "king of forage", and high-quality alfalfa is an important part of the forage production system. The industrialization of alfalfa plays an important role in promoting the development of herbivorous animal husbandry, improving the ecological environment, and developing low-carbon industries. With the development of the commodity economy, the planting area of ​​alfalfa in my country has been continuously expanding, and the scale of alfalfa industrialization has developed rapidly. [0003] Alfalfa is a dicotyledonous small-seeded plant (thousand-grain weight is only 2-2.2g), and it is difficult to top the soil when the seeds germinate; the suitable sowing depth is 5-30mm. If it is too deep, the cotyledons cannot brea...

Problems solved by technology

[0004] In the prior art, the traditional ditch openers for sowing alfalfa are mostly shovel-type structures, and there is a phenomenon of turning over the soil during the working process, which may easily cause the soil to mix dry and wet, which is not conducive to sowing in arid areas; at the same time, most of the seed furrows formed are V shape, which has a certain adverse effect on seed germination and growth; in addition, the sowing depth is shallow, which is not conducive to alfalfa overwintering in cold regions.
