Abstract

The invention relates to a soil modifier for sand storm hungry farmland, which belongs to the fertilizer production technical field. The modifier for sand storm hungry farmland is prepared by mixing grass carbon, dry pine needle, bentonite, natural zeolite, humus soil, decomposed farmyard manure, soil water-retaining agent, zinc sulfate and manganese sulfate. The application method is that 10000.0 kilograms modifier is applied to each hectare farmland. After using the modifier of the invention, the volume weight of soil is reduced by 4.3%, the soil hardness is reduced by 1.8%, the quick result K is increased by 10.4% and the organic matter content is increased by 16.1%. The invention provides the soil nutrition conditioning modifier capable for improving physicochemical property of the sand storm hungry farmland, and the nutrient element and the nutrient coordination substance required by plants are added, thereby the soil modifier of the invention has the effects of soil improvement, fertilizer efficiency enhancement and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production and is a soil improver. technical background [0002] In the western part of the Songnen Plain, there are a large number of barren farmlands with wind and sand, covering an area of ​​more than 7 million mu, which is one of the important commercial grain bases in my country. Due to the coarse soil texture, loose soil quality, weak ability to resist drought, easy wind erosion, poor organic matter, low fertility, poor water and fertilizer retention capacity, and low farmland production capacity, the formation of medium and low-yield fields. There is no ideal solution yet. Contents of the invention [0003] The technical problem to be solved by the invention is to disclose a soil conditioner for wind-sand barren farmland, so as to improve the soil properties of wind-sand barren farmland. [0004] The technical scheme to be solved in the present invention is to adopt peat, dried pine ...
