The salt content of the 0-20cm soil in the test plot is 4.3-7.8g / kg, which is a severe saline-alkali land, with a pH of 9.17, an organic matter content of 1.96g / kg, a total nitrogen of 0.19g / kg, and an alkali-hydrolyzed nitrogen of 23.44mg / kg. Available phosphorus is 5.51mg / kg, and available potassium is 307.28mg / kg. Location: Tiaozini Reclamation Area, Coastal Economic Zone, Dongtai City, located in the middle of Cangang Town, Dongtai City, Yancheng City, Jiangsu Province. It was formed by reclamation in 2013, and agricultural planting began in October 2015. In June 2016, the 0-20cm surface soil samples of the eastern low beach were collected as the soil for indoor simulation experiments, and the test time was from July 2016 to August 2016. The average salinity of the tested soil is 5.5g / kg, the pH is 9.08, the organic matter content is 1.75g / kg, the total nitrogen content is 0.17g / kg, the alkaline ...

Abstract

Disclosed are a mild type chemical conditioner applicable to saline-alkali soil and preparation and application methods thereof. The mild type chemical conditioner applicable to the saline-alkali soilis composed of an internal layer and an envelope layer, wherein the internal layer is composed of, by weight part, 40-50 parts of phosphogypsum, 15-20 parts of aluminum sulfate, 20-25 parts of humicacid, 10-15 parts of corncob powder and 5-8 parts of polyethylene glycol; the envelope layer is composed of water-soluble high-polymer polyacrylamide 0.08-0.12 time by weight as much as the mixed system of the internal layer. The mild type chemical conditioner applicable to the saline-alkali soil solves a series of practical problems of slow saline-alkali soil desalination process, significant alkalization trend during desalination, slow effects and long cycle of the prior art and the like.

Description

technical field [0001] The invention belongs to the technical field of farmland treatment of saline-alkali obstacles, and relates to a soil salinization improvement conditioner, in particular to a mild chemical improvement conditioner suitable for saline-alkali soils with different levels of obstacles, and a preparation method and application thereof. Background technique [0002] Soil salinization and secondary salinization are one of the main problems of soil degradation in my country and the world today. my country's saline soil resources are widely distributed in 17 provinces and regions mainly in the north. nearly 5% of the area. As a potential reserve land resource in my country, saline-alkali land has huge room for improving agricultural productivity, and its management is of strategic significance to realize the "expansion, quality improvement, and efficiency increase" of my country's cultivated land; at the same time, saline-alkali land is mainly distributed in the ...
