Problems solved by technology

These improvement methods have their own advantages and disadvantages. Water conservancy measures have quick results, but the amount of engineering is large and the cost is serious. The chemical improvement measures have a single function and the effect is suitable for each location. The biological improvement technology has a long cycle and low economic benefits.
Although there are many reports on the preparation of soil remediation agents for the improvement of saline-alkali land, but for the soil salinity of 1%-1.8%, the soil alkalinity is 30-40% of the heavily alkalized soil, the research on the preparation of soil amendments No report

Abstract

The invention discloses an alkali-affected soil amendment and its preparation method. According to the invention, cotton stalk is carbonized to prepare cotton stalk charcoal; moisture content of desulfurized gypsum is controlled; and cotton stalk charcoal, desulfurized gypsum, fulvic acid and compound sodium nitrate are mixed according to a certain ratio so as to prepare the alkali-affected soil amendment. The alkali-affected soil amendment contains, by weight, 200-300 parts of cotton stalk charcoal, 500-800 parts of desulfurized gypsum, 100-200 parts of fulvic acid and 2-5 parts of compound sodium nitrate. The prepared alkali-affected soil amendment can improve chemical composition of soil by replacing lots of sodium ions in soil. Thus, soil forms an aggregated structure, water permeability and air permeability of soil are enhanced, and a good environment is created for the growth of crops. The alkali-affected soil amendment plays an important role and is of great significance.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to the technical field of an alkalized soil conditioner and a preparation method thereof. Background technique [0002] Xinjiang is located in the hinterland of the Eurasian continent. Due to the high temperature and arid climate characteristics of large evaporation and little precipitation and the topographical characteristics of closed inland basins, a large area of ​​saline-alkali soil has been formed. According to the survey, the area of ​​various types of saline-alkali soil in Xinjiang reaches 1336.1×104hm 2 , accounting for 36.8% of the country's saline-alkali soil area, mainly distributed in the edge of the oasis and inside the oasis, and also sporadically distributed in the edge of the desert, the Gobi desert, and around the water-logged depressions and springs in the mountains. There are many kinds of saline-alkali soil in Xinjiang, which is called t...
