Description
Technical Field
The invention belongs to the technical field of saline-alkali soil conditioning, and particularly relates to a soil conditioning method for planting rice in saline-alkali soil in Xinjiang.
Background
The root cause of the formation of saline-alkali soil: under natural conditions, the soluble salts are redistributed in the horizontal direction and the vertical direction in the soil, so that the salts are slowly accumulated on the surface layer of the soil until the salt exceeds a normal level value. The factors influencing the soil salt accumulation in Xinjiang are various, and are not only related to the salt content contained in the soil matrix, but also have great relation with the external natural geography and ecological environment.
The European continental land plate in Xinjiang is an area which is the most arid in China, has the widest soil salinization distribution area, the most salinization types and the heaviest soil salt accumulation, and is rare in rainfall and strong in evaporation, so the European continental land plate is called a world museum of saline and alkaline land. According to statistics in 2001, the area of saline-alkali soil in Xinjiang is 2184.4 ten thousand hectares, which accounts for 22.01% of the total area of saline-alkali soil in China, in the farmland of 407 ten thousand hectares in Xinjiang, the farmland damaged by salinization of different degrees accounts for 122.88 ten thousand hectares, 30.12% of the total farmland area and 63.20% of the low-yield farmland area, wherein the low-yield farmland threatened by moderate and severe salinization accounts for 22.06% of the total farmland; in 1031 ten thousand hectares of suitable agricultural wasteland, the area limited by salt and alkali is 515.11 thousand hectares, which occupies 49.93 percent of the total area.
Except that the soil in parts of Ili river valley, Aleptai area and Tacheng area has less salt, other areas have salinization with different degrees, and the salinization and desertification coexist, the salt accumulation and surface aggregation are stronger, the soil salt component is complex, and the like.
The rice is a acidophilic plant, and researches show that part of rice varieties have certain saline-alkali resistance and can grow in saline-alkali soil, but the growth vigor is weak. Research shows that after the soil conditioner is added, soil activity can be effectively increased, and soil salinity can be reduced, but research areas aim at weak saline-alkali areas, saline-alkali treatment in Xinjiang areas is serious, and the current mode of rotary tillage applying of the single rice planting soil conditioner to soil cannot meet production requirements, so that the research on the method for conditioning the soil of rice planted in the saline-alkali soil in Xinjiang is particularly important.
