Special conditioner for saline-alkali soil white hyacinth bean planting and preparation method and application thereof

Abstract

The invention relates to a special conditioner for saline-alkali soil white hyacinth bean planting and a preparation method and application thereof. The special conditioner for the saline-alkali soil white hyacinth bean planting consists of the following raw materials: ardealite, chicken and duck feces, plant ash, bean dreg, vegetable residue and a starch-polyacrylamide compound. The preparation method thereof comprises the steps of performing joint fermentation for partial ardealite and chicken and duck feces, and then mixing the fermented materials with the remaining ardealite and a water-retaining agent. By applying the conditioner provided by the invention to the moderate and heavy saline-alkali soil in Ningxia area, the efficacies of retaining water, retaining fertilizer, reducing salinity, loosening soil and the like are achieved, and the conditioner is especially suitable for the planting of white hyacinth beans in saline-alkali soil. Compared with the prior art, the conditioner has the characteristics that the preparation method of the conditioner is simple, the soil application and the treatment are simple, convenient and feasible, the acidity and the alkalinity of the soil are appropriate, the organic matter components are rich and the like, moreover the growth of the white hyacinth beans in Ningxia saline-alkali areas can be fully promoted, the yield can be increased, the content of nutritional components in the white hyacinth beans is increased, and the conditioner is an ideal special conditioner for white hyacinth bean planting.

Description

technical field [0001] The invention relates to a special improver for white lentil planting in saline-alkali soil, a preparation method and application thereof, and belongs to the technical field of soil improvement. technical background [0002] Saline-alkali soil is a widely distributed soil type on the earth. The current area of ​​saline-alkali soil in the world is about 954 million hm 2 , distributed in the arid regions of all continents in the world, the total amount of saline-alkali soil resources in my country is about 99.13 million hm 2 , mainly distributed in the inland areas of Northeast China, North China, Northwest China and the coastal area north of the Yangtze River. Depending on the distribution of regions, saline-alkali soil is divided into four major types: coastal saline area, Huanghuai-Hai plain saline area, desert and desert plain saline area, and grassland saline area; in the process of utilization, it can be divided into light saline-alkali land ( Sa...

AI Technical Summary

Problems solved by technology

Generally, 4.8-5.0 tons of phosphogypsum will be produced from 1 ton of phosphoric acid produced by the sulfuric acid method, and with the development of the phosphate fertilizer industry, the discharge of phosphogypsum is increasing year by year. As of 2011, the accumulation of phosphogypsum in my country has exceeded 250Mt. At the end of the "Twelfth Five-Year Plan", the annual output of phosphogypsum is about 70Mt, which not only pollutes the environment, but also occupies a large amount of land. However, the current comprehensive utilization rate of phosphogypsum is only about 10%. Therefore, the comprehensive utilization and harmless of phosphogypsum Processing has become an important task for the phosphate fertilizer industry

At present, there are no reports on the application of phosphogypsum in combination with starch-polyacrylamide compound, decomposed chicken and duck manure, plant ash, bean dregs and vegetable dregs in the cultivation of white lentils in saline-alkali soil, especially in Ningxia area.
