Description

Technical Field

[0001] This invention relates to the field of soil continuous cropping obstacle improvement technology, specifically to a soil continuous cropping obstacle improvement device and method. Background Technology

[0002] Continuous cropping obstacles refer to the phenomenon where the same crop or crop of the same family is continuously planted on the same plot of land, resulting in soil degradation, such as salinization, acidification, soil compaction, decreased soil fertility, severe root-knot nematodes and soil-borne diseases and pests, leading to reduced crop yield, deteriorated quality, increased disease severity, poorer growth, or even complete crop failure. Vegetables are an important economic crop in China. In recent years, Shanghai's greenhouse vegetable industry has developed rapidly, with the city's annual vegetable planting area remaining stable at around 500,000 mu (approximately 33,333 hectares), maintaining a vegetable self-sufficiency rate of around 45%, and a leafy green vegetable self-sufficiency rate of around 85%, effectively ensuring the local supply of vegetables and becoming a major agricultural economic industry. However, due to the highly intensive, high multiple cropping index, and single crop variety characteristics of greenhouse vegetable production, coupled with the special enclosed environment that alters the water and salt balance, the physical, chemical, and biological properties of the greenhouse soil undergo significant changes. This leads to continuous cropping obstacles such as soil salinization, increased soil-borne diseases, reduced vegetable yield, and deteriorated quality, severely restricting the sustainable development of greenhouse vegetable production.

[0003] When existing devices apply soil conditioners to the soil, since most soil conditioners are in powder form, directly applying the powdered soil conditioner can cause it to be easily affected by external winds during the application process, resulting in strong winds blowing the powder away and thus affecting the soil improvement effect. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a device and method for improving soil continuous cropping obstacles, comprising:

[0005] The frame has an extension bracket fixedly connected to one side, a handrail fixedly connected to the end of the extension bracket away from the frame, and a traveling roller fixedly connected to the bottom of the frame via a bracket.

The diversion device passes through the storage frame and is fixedly connected to the bottom of the storage frame. The outer side of the diversion device is fixedly connected to the side of the frame through a bracket. The soil conditioner filled inside the storage frame enters the discharge sleeve through the feed frame. The soil conditioner in the discharge sleeve is discharged into the diversion device through the screw feeding mechanism. The diversion device directly sprinkles the powdered soil conditioner into the soil, avoiding the powdered conditioner from being blown away by external wind during the sprinkling process.

The top of the partition plate has an arc-shaped opening. When the fan blades rotate, external air can be drawn from the air inlet into the air collecting duct, and then discharged into the conveying pipe from the air collecting duct. At the same time, the spiral feeding mechanism inside the discharge sleeve transports the soil conditioner to the conveying pipe. At this time, the airflow can be used to blow the soil conditioner along the conveying pipe to the soil surface, accelerating the application speed of the agent and improving the application efficiency of the agent.
