Description

Furrow opener for alfalfa seeding machine and ditching and fertilizing mode
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a furrow opener for an alfalfa seeder and a furrow opening and fertilizing mode.
Background
As is well known, alfalfa is known as the king of forage grass, and high quality alfalfa is an important component of a forage grass production system. The industrialized development of the alfalfa plays an important role in promoting the development of the herbivore and animal husbandry, improving the ecological environment, developing the low-carbon industry and the like. With the development of commodity economy, the planting area of the alfalfa in China is continuously enlarged, and the industrialized scale development of the alfalfa is fast.
Alfalfa is a dicotyledonous small seed plant (the thousand seed weight is only 2-2.2g), and the soil jacking is difficult when seeds germinate; the suitable sowing depth is 5-30mm, too deep can cause cotyledons not to break through soil to cause seedlings to die, and too shallow can cause seeds not to germinate due to insufficient water or to be air-dried after germination. In addition, when the alfalfa is planted in cold regions, the main factor influencing the planting success rate and the yield is the overwintering capacity of the alfalfa, the root neck is the part where the alfalfa branches and overwintering buds grow, and researches show that the deeper the alfalfa root neck is buried, the stronger the cold resistance and the pasturing resistance of the alfalfa are.
In the prior art, the traditional furrow opener for alfalfa seeding is mostly of a shovel type structure, and soil turning phenomenon exists in the working process, so that dry-wet mixing of soil is easy to cause, and seeding in arid areas is not facilitated; meanwhile, the formed seed ditches are mostly V-shaped, and certain adverse effects are caused on the germination and growth of seeds; in addition, the sowing depth is shallow, which is not beneficial to the alfalfa overwintering in cold regions.
