Problems solved by technology

Since the saline-alkali soil improver contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic materials, it is more difficult to dissolve after granulation, and the granulation affects the quality of the product. and effects
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products

Embodiment 1

[0018] Saline-alkali land improver, which is prepared from vegetable garden soil, active functional bacteria, mineral powder, organic fertilizer, inorganic compound fertilizer, and water, wherein 25wt% of vegetable garden soil, 5wt% of active functional bacteria, 5wt% of mineral powder and 25wt of organic fertilizer %, inorganic compound fertilizer 20wt% water 20wt% is prepared from, and active function bacterium comprises bacillus licheniformis: colloid bacillus is mixed in the ratio of 5:2:3; Described composite microbial agent, mineral powder is peat, zeolite, A mixture of one or more of vermiculite, montmorillonite, calcium carbonate, and expanded perlite, the fineness of the mineral powder is ≤200 mesh, and the organic fertilizer contains decomposed manure, rapeseed cake fertilizer, and straw. The weight ratio of manure, rapeseed cake fertilizer and straw is 5.5: 2.5: 0.5; the inorganic compound fertilizer component contains urea 10~20wt%, superphosphate 10~15wt%, potassiu...

Embodiment 2

[0029] A saline-alkali soil improver, which is prepared from 35wt% of vegetable garden soil, 10wt% of active functional bacteria, 15wt% of mineral powder, 25% of organic fertilizer, 15% of inorganic compound fertilizer, and water. The active functional bacteria include lactic acid bacteria and Bacillus subtilis , Bacillus megaterium, Trichoderma, Aspergillus niger, Monascus, Trichoderma harzianum, Aspergillus aculeatus and yeast, the mineral powder is one of peat, zeolite, vermiculite, montmorillonite, calcium carbonate, expanded perlite or More than one mixture, the fineness of the mineral powder is ≤200 mesh, the organic fertilizer contains decomposed manure, rapeseed cake fertilizer, and straw, and the weight ratio of the manure, rapeseed cake fertilizer and straw is 7.5:3.5:1.5; The inorganic compound fertilizer component contains 10-20 wt% of urea, 10-15 wt% of superphosphate, 25-30 wt% of potassium sulfate, 25-30 wt% of potassium nitrate, 10-15 wt% of diammonium phosphate...

Embodiment 3

[0041] Application of saline-alkali soil improver:

[0042] Using random block method, the area of ​​the plot is 100m 2 , set 3 repetitions, use 50kg / mu of the saline-alkali soil improver as base fertilizer in embodiment 1 and embodiment 2. They are treatment group 1 and treatment group 2 respectively.

[0043] Common compound fertilizer was used as base fertilizer to apply 50kg / mu, which was treatment group 3.

[0044] The area without fertilizer application was used as the control area.

[0045] Use the checkerboard sampling method to record the number of pest plants in each plot, and calculate the control effect according to the following formula:

[0046] Control effect (%)=(the number of insect-damaged plants in the control area-the number of insect-damaged plants in the treatment area) / the number of insect-damaged plants in the control area×100% of the above groups, except that the base fertilizer applied is different, and the later topdressing and management are the ...

Abstract

A saline soil improver is characterized by comprising 25%-35wt% of vegetable soil, 5%-10wt% of active functional bacteria, 5%-15wt% of mineral powder, 25%-30wt% of an organic fertilizer, 15%-20wt% of an inorganic compound fertilizer and balance of water, the active functional bacteria includes lactic acid bacteria, bacillus subtilis, bacillus megatherium, trichoderma, aspergillus niger, Monascus, Trichoderma harzianum, Aspergillus aculeatus and yeast, the mineral powder is one of or a mixture of more than one of peat, zeolite, vermiculite, montmorillonite, calcium carbonate and expansion perlite, the mineral powder fineness is less than or equal to 200 meshes. The organic fertilizer contains composted manure, a rapeseed cake fertilizer and straws, and the weight ratio of composted manure to rapeseed cake fertilizer to straws is 5.5-7.5: 2.5-3.5: 0.5-1.5.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a saline-alkali soil improver and a preparation method thereof. Background technique [0002] The saline-alkali soil improver has comprehensive nutrients, which can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the saline-alkali land improver enter the soil and form a mutual symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group, and the beneficial bacteria grow and reproduce A large number of metabolites are produced during the process, which promotes the decomposition and transformation of organic ...
