Conditioner for saline land and preparation and application methods thereof

Abstract

The invention discloses a conditioner for saline land. The conditioner of the invention comprises the following raw materials (by weight): 5-10 parts of lactose acetate, 5-10 parts of maltose acetate,5-10 parts of glucose peracetate, 10-15 parts of cured bean dregs, 30-50 parts of a bio-organic fertilizer, 3-5 parts of ferrous bisglycinate, 1-5 parts of zinc acetate and 1-5 parts of zinc stearate. The preparation method of the conditioner comprises the following steps: firstly weighing lactose acetate, maltose acetate, glucose peracetate, cured bean dregs, ferrous bisglycinate, zinc acetate and zinc stearate according to the above weight ratio, and respectively crushing the above materials into fine powder of 80-120 meshes; and then pouring all the raw materials into an agitator and uniformly stirring. According to the application method of the conditioner, the conditioner is applied as a base fertilizer to saline-alkali soil at a time: application amount of the conditioner for each mu of strongly saline-alkaline soil is 60-80 kg; application amount of the conditioner for each mu of moderate salinized soil is 40-60 kg; and application amount of the conditioner for each mu of mildsalinized soil is 20-40 kg.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a soil conditioner for saline-alkali land. Background technique [0002] Saline-alkali land is an important land resource. The area of ​​saline-alkali soil in the world is about 1 billion hectares. my country has 99.13 million hectares, accounting for about 10% of the world's total. It is mainly concentrated in the arid and semi-arid areas of North China, Northwest and Northeast China . About 80% of saline-alkali land in my country has not been utilized. The development of large-scale saline-alkali land and the prevention and control of soil salinization in irrigation areas will be an important way to solve my country's food problems in the 21st century. [0003] The improved saline-alkali technologies at home and abroad mainly include physical improvement, chemical improvement, biological improvement and water conservancy improvement. There are many types...

Problems solved by technology

At present, the main problems in the improvement of saline-alkali land are as follows: secondary salt disasters and soil pollution are easily caused during the improvement process; the effectiveness is short, and the improvement of soil physical and chemical properties is ignored; the survival rate of beneficial microorganisms is low, and it is difficult to develop Function; soil organic matter content is low, nutrient content is not high, the ratio of nitrogen and phosphorus is out of balance, organic fertilizer is insufficient, coupled with the cementation of calcium ions, the soil compaction is serious

In recent years, improving soil with organic amendments has become a hot topic in soil improvement research, because the common characteristics of salinized soil are low organic matter content, poor soil physical and chemical properties, many anions and cations harmful to crop growth, and low survival rate of beneficial microorganisms , the soil fertility is low, and the crops are not easy to promote the growth of seedlings
