Comprehensive optimization treatment technology for saline-alkali soil

Abstract

The invention relates to a comprehensive optimization treatment technology for saline-alkali soil, which is characterized in that the following measures are applied to saline-alkali soil to reduce the salt content of the soil: scarifying surface soil, paving a far infrared mineral base material, blending organic fertilizer, planting oil miscanthus of halophyte, harvesting to remove the salt content, and finally detecting the salt content and pH value of the soil. The far infrared mineral base material can generate shockwaves which can miniaturize water molecules so as to accelerate the salt absorption benefit of the oil awns, and meanwhile, the far infrared mineral base material has physical, chemical, biological and fertility properties and can be combined with organic fertilizer to promote the growth of the oil awns; the oil miscanthus crops can adsorb return salt of the oil miscanthus when the oil miscanthus is evaporated on the soil surface so as to dilute salt in the soil and underground water, the harvested oil miscanthus can supplement insufficient nutrition of the rice and the wheat, and the oil miscanthus straws can be used as feed and can be eaten by seeds, so that the oil miscanthus has great economic value; therefore, the far infrared mineral base material and the oil miscanthus are used and supplement each other, so that the soil of the saline-alkali soil can be effectively improved, and meanwhile, the benefit of soil optimization can be increased by virtue of the economical efficiency of the oil miscanthus.

Description

technical field [0001] The invention relates to a soil optimization, especially a comprehensive optimization treatment technology for saline-alkali soil which uses far-infrared mineral base material and oil awn to complement each other to effectively reduce soil salinity and increase the economic value of crops. Background technique [0002] According to statistics, saline-alkali land refers to the soil with high salt content and pH value greater than 9, which makes it difficult for plants, especially crops to grow; according to United Nations statistics, the area of ​​saline-alkali land in the world is as high as 954.38 million hectares. It is the main cause of food shortage in many countries; saline-alkali land is not conducive to the cultivation of food crops, so human beings have been making continuous efforts for a long time, hoping to improve the growth effect of crops by reducing soil salinity; Including: 1. Soil washing method, its structure is as follows figure 1 A...

[0002] By the way, saline-alkali land refers to the land with high salt content in the soil and a pH value greater than 9, which makes it difficult for plants, especially crops, to grow; according to United Nations statistics, the saline-alkali land area in the world is as high as 954.38 million hectares. The main cause of food shortage in many countries around the world; saline-alkali land is not conducive to the cultivation of food crops, so human beings have been working hard for a long time, hoping to improve the growth of crops by reducing soil salinity; according to the current more specific saline-alkali land governance model Including: 1. Soil washing method, its structure is as follows: figure 1 As shown, it includes an open ditch 91, a water collecting pipe 92, a water collecting well 93, a drain pipe 94, and a treatment pond 95. The method is to use a large amount of fresh water to flush and confluence the salt 81 in the soil 90 to form a salt water 80 in the treatment pond 95. Finally, the brine 80 is removed; this method is similar to the natural desalination phenomenon, wherein, after the salt 81 is separated from the surface soil, a part enters the treatment pond 95 and is removed, and most of the salt 81 falls to the Deep groundwater; when there is a drought, the evaporation is strong, and the salt 81 in the groundwater returns to the surface of the soil 90 with the capillary uplift; therefore, the soil washing method cannot effectively reduce the salt,
