Alfalfa field improvement device

Abstract

The invention relates to an alfalfa field improvement device, and belongs to the field of agricultural machinery. The alfalfa field improvement device in the invention mainly comprises a soil loosening and root cutting mechanism and a seed and fertilizer guide mechanism; the soil loosening and root cutting mechanism comprises a connection plate, a front fixed plate, a spring end cover, an excitingvibration spring, a spring fixing bolt, a spring limiting cover, a rear fixed plate, a fixed beam, a left wing shovel, a shovel head, a right wing shovel and a deep loosening shovel handle; and the seed and fertilizer guide mechanism comprises a fertilizer guide pipe, a seed guide pipe, a soil covering plate, a guide pipe fixing part and a ditching wedge. According to the alfalfa field improvement device in the invention, soil loosening improvement operation can be carried out for the artificial alfalfa field soil compaction problem, so that the gas permeability of soil is improved; due to arrangement of double-wing bionic root cutting shovels, perennial artificial alfalfa taproots can be cut effectively, so that stems and leaves of alfalfa are promoted; inter-planting of gramineous forage seeds and lateral deep fertilization can be carried out; the aboveground space utilization rate is reasonably increased; development of the root system reaches the best state; and thus, the annual yield of herbages is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an alfalfa field improvement device. Background technique [0002] Alfalfa is currently the forage grass with the largest planting area, the highest usable value, and the widest distribution in the world. It has the title of "King of Forage Grass". Its crude protein content can reach 18%, much higher than that of corn and wheat. In 2015, the No. 1 document of the central government proposed to "accelerate the development of grass and animal husbandry, support the planting of forage materials such as silage corn and alfalfa, carry out pilot projects of grain-to-forage and combination of planting and breeding, and promote the three-way planting of grain, cash crops, and forage. An important instruction for the coordinated development of the structure. According to the "National Alfalfa Industry Development Plan (2016-2020)" issued by the Ministry of Agriculture, in...

AI Technical Summary

Problems solved by technology

[0003] The research and development of perennial artificial alfalfa field improvement machinery has important practical significance and economic value: First, artificially planted alfalfa can be harvested 4 to 7 times a year, and agricultural machinery is used for field management operations all year round, which will lead to increased soil bulk density and porosity. The change of the root system and the increase of the penetration resistance of the root system affect the absorption of nutrients by the crops. The result is the deterioration of the soil condition, the reduction of alfalfa production, and the increase of energy consumption for machine operations. Seriously affects the nutrient absorption of the stem and leaf, leading to a decline in alfalfa yield; finally, the long-term planting structure is single, resulting in a decline in soil fertility, loss of biodiversity, and aggravation of pests and diseases
