[0002] Saline-alkali land refers to the general name of various types of soils that contain too much saline-alkali components in the soil, including saline soil and alkaline soil, and other types of soil that have undergone a certain degree of salinization or alkalization. Saline soil refers to a large amount of soluble salts that make most plants Soil that cannot grow. Alkaline soil refers to the soil where the percentage of substitutable sodium ions accounts for more than 20% of the cation replacement capacity and the pH value exceeds 8. In fact, because saline soil and alkaline soil are often interlaced, it is customary to collectively call them saline-alkali soil. , saline-alkali land is more harmful, mainly manifested in restricting agricultural production, destroying the ecological environment and affecting sustainable development; saline-alkali land improvement has always been one of the important topics of concern and research by workers in related fields. The ecological environment and the promotion of agricultural economic development; the current improvement methods of saline-alkali land are divided into physical improvement, biological improvement and chemical improvement. Among them, physical improvement is to drain and wash salt on saline-alkali land by establishing a sound drainage and irrigation system. Although this method can be used in a short period of time Saline-alkali land treatment effect is achieved, but the scale of the project is huge, the investment is large, and water resources are consumed; biological improvement is to improve the ecological environment of saline-alkali land by planting saline-alkali-tolerant green plants on saline-alkali land, but the treatment cycle is long and the effect is slow; Adding substances with the properties of neutralizing alkalinity and absorbing salt to the saline-alkali land can reduce soil salinity, but it is easy to introduce other salts into the soil, resulting in insignificant or further deterioration of the saline-alkali land treatment effect

Abstract

The invention belongs to the technical field of saline-alkali land improvement, and specially relates to a pig manure compound fertilizer special for saline-alkali land improvement. Raw materials of the pig manure compound fertilizer comprise, in parts by weight, 46 to 60 parts of pig manure, 16 to 20 parts of straw, 10 to 18 parts of humic acid, 9 to 18 parts of acetic anhydride, 3 to 6 parts ofglucose, 0.3 to 0.6 part of sulfamic acid, and 0.2 to 0.5 parts of EM probiotic stock solution. Acetylated glucose is generated from glucose and acetic anhydride under catalysis of sulfamic acid, wherein the sulfamic acid is moderately acidic, colorless, odorless, non-volatile, non-hygroscopic and stable in properties, and compared with conventional toxic and harmful catalysts used in acetylationreactions, the sulfamic acid is environmentally friendly and has the characteristics of low toxicity and harm to human body. In the acetylated glucose, hydroxyl and amino groups in glucose are both protected by acetyl groups, the nutrient use efficiency of the acetylated glucose is high, and when the acetylated glucose is applied to soil, glucose generated through decomposition not only has a promoting effect on crop growth, but also is conducive to microbial reproduction.
