Abstract

The invention belongs to the technical field of soil conditioners and particularly relates to a method for producing a natural and organic conditioner for strong-alkalinity saline-alkali soil. The process comprises the following steps: (1) weighing 25-50 parts (by weight) of calcium superphosphate, adding 1-2 parts (by weight) of ammonium molybdate, and uniformly stirring, so as to obtain a mixture; (2) weighing 600-800 parts (by weight) of young lignite, 100-150 parts (by weight) of magnesium sulfate heptahydrate and 25-50 parts (by weight) of ferrous sulfate heptahydrate, thoroughly mixing with the mixture obtained in the step (1), so as to obtain a mixture, and storing the mixture in a sealed packaging manner; and (3) weighing 150-200 parts (by weight) of ammonium sulfate, 25-50 parts (by weight) of potassium chloride and / or potassium sulfate, 25-50 parts (by weight) of ammonium dihydrogen phosphate, 25-50 parts (by weight) of calcium sulfate and 25-50 parts (by weight) of urea, and thoroughly mixing with the mixture obtained in the step (2). According to the method provided by the invention, the soil conditioner is prepared in a manner of using the young lignite, which is high in quality and is cheap, as a main raw material, the raw material and production costs are relatively low, and the conditioner can serve as a soil fertilizer to improve fertility while having the function of improving the salinity and alkalinity of soil.

Description

technical field [0001] The invention belongs to the technical field of soil improvers, in particular to a production method of a natural organic saline-alkaline soil improver. Background technique [0002] In recent years, due to factors such as continuous excessive use of chemical fertilizers, the actual control effect of saline-alkali soil in my country is not optimistic. The traditional method of flooding and pressing alkali in hot summer days is labor-intensive and water-intensive and treats the symptoms but not the root cause. The method of alkali control and soil improvement in the chemical scheme brings secondary pollution to agricultural products, soil and the surrounding environment. Utilize cheap and easy-to-obtain peat moss (peat) and MgSO 4 ·7H 2 O Cooperating with soil improvement and management, the effect is more advantageous than other methods, but the problem is that peat (peat) is not renewable, and it is also a product of wetlands that are vital to the ...
