Equipment and method for applying additional water-soluble fertilizers to medicago

Abstract

The invention discloses equipment and a method for applying additional water-soluble fertilizers to medicago. The equipment comprises a framework. The framework comprises a fixed frame and a vertical movable frame, a vertical strip-shaped groove is formed in the fixed frame, and the vertical movable frame is fixedly connected into the strip-shaped groove in such a manner that the vertical movable frame can be longitudinally vertically repositioned; a fertilizer tank is arranged on the fixed frame, travel wheels are arranged at the lower end of the fixed frame, a fertilizer application wheel is arranged at the lower end of the vertical movable frame, and a furrowing disc is arranged between the travel wheels and the fertilizer application wheel and is fixedly connected to the lower side of the vertical movable frame; the fertilizer tank is connected with one end of a water outlet pipe, a plurality of branch flow pipes are connected with the other end of the water outlet pipe and are connected with one end of a fertilizer application pipe by flow pumps, and the other end of the fertilizer application pipe extends onto the fertilizer application wheel. The equipment and the method have the advantages that the medicago is planted in a drill seeding manner, and the additional water-soluble fertilizers can be applied to the medicago by the aid of the equipment for applying the additional water-soluble fertilizers while the medicago is harvested; problems of difficulty in applying additional fertilizers, low fertilizer utilization rate, unstable additional fertilizer application periods and the like in existing medicago planting procedures can be solved by the aid of the equipment and the method.

Description

technical field [0001] The invention mainly relates to the agricultural production in the rain-fed and dry-farming area of ​​the Heilonggang River Basin, in particular to equipment and a method for topdressing water-soluble fertilizer for alfalfa. Background technique [0002] With the continuous improvement of people's living standards, alfalfa, as a high-quality high-protein forage grass, has been paid more attention in recent years, and the planting area has been continuously expanded. However, in the traditional alfalfa planting process, there is no systematic topdressing method for alfalfa, which may easily cause fertilizer deficiency in the later stage, resulting in a decline in yield and quality. There are two traditional topdressing methods for alfalfa planting: [0003] One is not top-dressing, alfalfa is cut several times a year, and long-term non-top-dressing is likely to cause soil nutrient deficiency, affecting the normal growth of alfalfa. [0004] The second...
