preparation example Construction
[0031] The invention provides a kind of preparation method of biological saline-alkali soil conditioner for saline-alkali land, which comprises the following steps:
[0032] A. Production of mixed bacterial agents
[0033] a. Expand the strains to fresh test tube beef extract peptone slant medium; cultivate and mature in 28-32°C incubator for 3-5 days; then inoculate in the culture medium for shaker culture;
[0034] b. When the number of bacteria in the liquid is ≥ 2 billion / ml, it enters the first-stage fermentation stage; the seeds are hydraulically put into the fermenter by the differential pressure method; the pressure is controlled at 0.03-0.05Mpa, the temperature is 26-28°C, and the sterile air ventilation is the tank 0.5-1 times the volume; the amount of the seed liquid is based on the volume of the primary fermentation tank, and the inoculation amount is 0.1%-10%;
[0035] c. After the primary fermentation of the b step is completed, the bacteria are liquidized into ...
Embodiment 1
[0049] In step C, the mixed bacterial agent, organic regulator and additive are mixed and stirred uniformly in a weight ratio of 55:35:15; fermented at 33°C for 7 days, and then dried to a moisture content of 28% to obtain a biological saline-alkali soil improver ;
[0050] The improvement agent was tested for cotton planting in saline-alkali land, and the application effect was as follows: the emergence rate increased by 17%, the number of seedlings increased by 8%, the seed cotton income increased by 12%, the water-soluble salt decreased by 33.1%, and the pH value decreased by 1.31.
Embodiment 2
[0052] In step C, mix and stir the mixed bacterial agent, organic regulator and additives in a weight ratio of 50:30:20; ferment at 30°C for 5 days, and then dry to a moisture content of 26% to obtain a biological saline-alkali soil improver ;
[0053] The improvement agent was tested for cotton planting in saline-alkali land, and the application effects were as follows: the emergence rate increased by 19%, the number of seedlings increased by 9%, the seed cotton income increased by 13%, the water-soluble salt decreased by 34.3%, and the pH value decreased by 0.89.

Abstract
The invention relates to the technical field of modifiers, particularly to a preparation method of a biological saline-alkali soil modifier for saline-alkali soil. The preparation method comprises: preparing a mixing bacterial agent; preparing an organic regulator; preparing an additive; mixing the mixing bacterial agent, the organic regulator and the additive according to a weight ratio of 45-60:15-40:15-25, and uniformly stirring; and fermenting for 5-7 days at a temperature of 30-33 DEG C, and drying until the water content is less than 30% so as to obtain the biological saline-alkali soilmodifier. According to the present invention, a variety of strains are respectively subjected to amplification inoculation on a culture medium, and are cultured in an incubator to achieve a mature state, the obtained strains are inoculated into a culture liquid, shaking culture is performed, two-stage fermentation is performed in fermentation tanks, the bacteria obtained by the fermentation are adsorbed by carriers to obtain the mixing bacterial agent, the mixing bacterial agent, the organic regulator and the additive are mixing according to a certain weight ratio, and are uniformly stirred, fermentation is performed, and drying is performed to obtain the biological saline-alkali soil modifier; and after the biological saline-alkali soil modifier is applied, the growth indexes of crops canbe substantially improved, and the yield of crops can be increased.
Description
technical field [0001] The invention relates to the technical field of improvers, in particular to a preparation method of a biological saline-alkali soil improver for saline-alkali land. Background technique [0002] my country's saline-alkali soil has a large area and complex types. Due to the accumulation of a large amount of salt in the soil, a series of soil physical properties have deteriorated: sticky structure, poor ventilation, high bulk density, slow rise in soil temperature, and poor activity of aerobic microorganisms in the soil. The release is slow, the permeability coefficient is low, and the capillary action is strong, which leads to the aggravation of surface soil salinization. [0003] With the continuous development of coastal beaches, many difficulties have been encountered in the improvement and utilization of saline-alkali land. In order to make full use of coastal tidal land, people have adopted various methods such as ditches to reduce water and drain ...
