Description

A kind of using method of alkaline land improving fertilizer

 

Technical field:

The present invention relates to a kind of agricultural fertilizer material technical field, relate in particular to a kind of using method of alkaline land improving fertilizer.

 

Background technology:

Saltings is most of relevant with the accumulative total of Carbonates In Soil, and basicity is generally higher, and serious salt affected soil regional plant almost can not be survived.Saltings utilizing in the middle of process, is simply said, can be divided into light saltings, moderate saltings and heavy saline.Light saltings refers to emerging very likely of it, and saltiness is below 3/1000ths; Heavy saline refers to that its saltiness surpasses 6/1000ths, and seedling rate is lower than 50%, and moisture in soil pH value surpasses 8.5, causes soil compaction, and the root system of crop is had to restraining effect, crop is not grown or grow unhealthy; Moderate saltings is between between the two.Improvement for saltings, chemical process has good effect, chemical modifying is exactly that some acid salts substances of application are improved the character in saltings, reduce the potential of hydrogen of soil, increase the positively charged ion replacement ability of soil, reduce the saltiness of soil, strengthen the activity of Soil Microorganism and enzyme, promote plant root growth.Improve the physical properties of soil, increase soil aggregate, coordinate soil water fat gas heat, increase soil fertility.But chemical modifying easily causes chemical composition residual, so biological modification method becomes the main flow in market, traditional biological control measure improvement saltings, uses plant improvement saltings, easy to implement the method, remarkable in economical benefits.Biological control measure can change the physical property of soil gradually, and Soil structure is changed, and it is loose that quality becomes, and ventilative and water storage capacity strengthens.Therefore, it is simple that the present invention aims to provide a kind of using method, and the product proportioning of use is simple, easy to use, reduces the saltiness of soil, strengthens the activity of Soil Microorganism and enzyme, promotes the using method of a kind of alkaline land improving fertilizer of plant root growth.

 

Summary of the invention:

The object of the invention is to overcome the shortcoming existing in prior art, provide a kind of using method simple, the product proportioning of using is simple, easy to use, reduce the saltiness of soil, strengthen the activity of Soil Microorganism and enzyme, promote the using method of a kind of alkaline land improving fertilizer of plant root growth.

To achieve these goals, the invention provides a kind of using method of alkaline land improving fertilizer, it is characterized in that, comprise the steps:
