Restoration type saline-alkali soil conditioner and preparation method thereof

Abstract

The invention discloses a restoration type saline-alkali soil conditioner which comprises the following raw materials in accordance with parts by weight: 90 to 107 parts of active organic fertilizer, 100 parts of gypsum powder, 1.8 to 2.2 parts of phosphatic fertilizer and 0.38 to 0.41 parts of composite functional germs, wherein the mass of the composite functional germs in total mass of the raw materials is two parts per thousand, and each gram of the composite functional germs contains more than 20 billions of effective germs. According to the restoration type saline-alkali soil conditioner provided by the invention, on the basis of regulating the ph value of saline-alkali soil, the content of sodium salt which is not beneficial for crop growth is reduced; soil organic matter is increased; the soil hardening phenomenon of the saline-alkali soil is improved; the permeability of the soil and the capability for preserving moisture and fertility are improved; because the active organic fertilizer contains a large quantity of microelements and active substances, nutrition for early growth of crops is guaranteed; and by adding the composite functional germs, the utilization ratio of the active organic fertilizer is increased, and the growing environment of roots of the crops is improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biological fertilizer. Background technique [0002] There are large areas of saline-alkali land in Xinjiang and other regions, and improving the soil quality of saline-alkali land has become a major plan for survival. The improvement method for saline-alkali land such as Xinjiang mainly adopts the traditional salt washing method, but this method takes at least three years, that is to say, within three years, the saline-alkali land can only be abandoned, which takes too long, and this method It can only improve the salinity of saline-alkali land, but it cannot provide the crops with the nutrition and other living environment needed for growth. Even if the salinity of the soil is improved, it is difficult to directly use it for planting or only plant grass and other low-demanding living environment. Vegetation, if you want to grow crops, you need to further improve and condition the soil. Cont...
