Abstract

The invention discloses a method for improving tobacco planting soil by returning straw stalks to the field. The method comprises the following steps that obtained straw stalk powder is added into a charging barrel along a feeding hopper, the straw stalk powder is spirally extruded from a discharge port of the charging barrel, so that the straw stalk powder extruded from the discharge port is granulated, and the straw stalk powder is changed into straw stalk granules; a granulating mechanism is mounted on a partition plate, so that the granulated straw stalk particles uniformly fall into fertilization bins on the two sides of a fertilization box; a front wheel shaft and a second gear on the front wheel shaft are driven to rotate, the second gear drives a third gear to rotate through a transmission gear and a first chain, and the third gear drives a material stirring shaft and a fertilizing wheel on the material stirring shaft to rotate; and when the fertilizing wheel rotates, the fertilizer located in an arc-shaped groove is uniformly scattered in a groove formed by a front ditching plate and a rear ditching plate. The method for improving the tobacco planting soil by returning the straw stalks to the field has the advantages that rice straw particles and organic fertilizers in the market are fully mixed, and uniform fertilization can be realized.

Description

technical field

[0001] The invention belongs to the technical field of agricultural planting, and relates to a method for improving tobacco planting soil, in particular to a method for improving tobacco planting soil by returning rice straw to the field. Background technique

[0002] Tobacco is an important economic crop, which plays a huge role in supporting my country's national economy. Continuous cropping is common in tobacco production, and continuous cropping leads to the depletion and uneven enrichment of soil nutrients in tobacco planting, resulting in the imbalance and deterioration of soil nutrients, which in turn affects the absorption of soil nutrients by tobacco. In addition, the transpiration rate of continuous cropping tobacco decreases, photosynthesis weakens, and the potassium content of plants decreases, which has adverse effects on tobacco growth. What's more serious is that continuous cropping will not only inhibit the growth of tobacco, but also lead to...
