Salt and alkali decomposing biological bacterial fertilizer

Abstract

The invention relates to a salt and alkali decomposing biological bacterial fertilizer. The salt and alkali decomposing biological bacterial fertilizer is prepared through the following components by mass percentage: 65 to 80% of humic acid, 1 to 4% of EM bacteria, 5 to 15% of nitrogenous fertilizer, 5 to 11% of phosphatic fertilizer, and 5 to 11% of potash fertilizer. The salt and alkali decomposing biological bacterial fertilizer is prepared by the following steps: (1) mixing and uniformly agitating humic acid and EM bacteria, and fermenting for 72 to 96 hours at a temperature of 20 to 30 DEG C until the number of beneficial bactera in the mixture per kg is less than 20 million, thus obtaining a fermented material; and (2) adding nitrogenous fertilizer, phosphatic fertilizer and potash fertilizer to the fermented material obtained in the step (1); and uniformly mixing to obtain the salt and alkali decomposing biological bacterial fertilizer. The salt and alkali decomposing biological bacterial fertilizer is subjected to site-directed experience of three years in Ninghe County, Tianjin; the salt and alkali decomposing biological bacterial fertilizer added to the soil of which the pH (Power Of Hydrogen) is below 10 can decrease the pH of the soil by about 0.8 averagely each year; and after the salt and alkali decomposing biological bacterial fertilizer is used in three consecutive years, the pH of soil can reach a normal level, and as a result, the rate of survival of crops is greatly increased.

Description

technical field [0001] The invention relates to a biological bacterial fertilizer, in particular to a salt-alkali decomposing biological bacterial fertilizer. Background technique [0002] There are more than 30 million mu of saline-alkali land in my country. In places with heavy saline-alkali, no grass can grow, and in places with light-saline-alkali, some specific plants can grow but the yield is very low. In the case of our country's large population and decreasing arable land, the transformation and management of these tens of millions of acres of saline-alkali land has far-reaching historical and practical significance for the sustainable development of my country's agriculture. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a saline-alkali-dissolving biological bacterial fertilizer that is simple to manufacture, has good effect, requires less investment, and has quick results, and c...
