Embodiment Construction

[0012] The aeolian soil used was collected from the Daqinggou Sand Ecological Experiment Station of the Shenyang Institute of Applied Ecology, Chinese Academy of Sciences on the southeastern edge of the Horqin Sandy Land (the geographical location is 122°21′ east longitude, 42°58′ north latitude, the altitude is about 250m, and the annual average temperature is 6℃, annual rainfall is about 450mm); the peat is collected from the nearby Xinshengtun Village.

[0013] The peat is mixed into the aeolian soil, and then the improved aeolian soil with improved structure, water retention and organic matter content is obtained; the peat is air-dried, crushed and sieved, the pH value is 5.5, and the organic matter content is 773.6 g kg -1 , standby when the water content is 5%-6%; the pH value of the aeolian soil is 7.4, and the organic matter content is 29.1g kg -1 , when the water content is 1.5%-2%, it is ready for use; the mass percentage of peat in the mixed aeolian soil is 2%-8%. ...

Abstract

The invention relates to control of sandy soil, in particular to a method and application for improving aeolian sandy soil by using peat in the southeast region of Horqin Sands. Peat is mixed in aeolian sandy soil so as to improve the texture, structure, moisture retention and organic content of the soil. After mixing, the aeolian sandy soil contains 2-8 percent of peat by weight percent. When the aeolian sandy soil with peat is used for planting celery cabbage, both production and quality of celery cabbage are increased, and plant height, dry weight, fresh weight and root length of celery cabbage are greatly increased.

Description

technical field [0001] The invention relates to a treatment of sandy soil, in particular to a method for improving aeolian soil with peat and its application, which is suitable for the southeastern edge of the Horqin sandy land. Background technique [0002] Land desertification has become a major global environmental problem. China is one of the countries most seriously affected by desertification in the world. The Horqin Sandy Land is the largest sandy land in my country. Its southeastern part belongs to the transition zone from forest to grassland. It is an interlaced area of ​​agriculture and animal husbandry. The population is relatively dense. The soil is mainly aeolian sandy soil with low nutrient content and low land productivity. relatively backward. Therefore, how to improve land productivity and land use efficiency, speed up the transformation of the extensive production mode based on animal husbandry to the intensive production mode combining agriculture and ani...
