Problems solved by technology

The third is improper cultivation management, such as too shallow cultivation, fertilization on the soil surface and pouring water, etc., which can increase the accumulation of salt to the surface of the soil.
In addition, the high groundwater level in the protected area and the high salinity of irrigation water are also likely to cause increased soil salinity

[0035] The vinegar grains are fresh and uncorrupted, and the water content is less than 80%.

[0036] The sawdust is poplar sawdust, which is fresh and uncorrupted.

[0037] The shale mentioned above is calcareous shale rich in trace elements.

[0038] The magnesium sulfate is MgSO 4 ·7H 2 O.

[0039] The zinc sulfate is ZnSO 4 ·7H 2 O.

[0040] The borax is Na 2 B 4 o 7 10H 2 O.

[0041] The microbial strains are composed of 4 different microorganisms, belonging to Clostridium themocellum (Clostridium themocellum), which are freeze-dried strains, which are commercially available products, preserved and purc...

example 1

[0055] Example 1 field test results: Greenhouse cucumbers have been planted continuously for seven years in Jinci Town, Jinyuan District, Taiyuan City, Shanxi Province, eggplants have been planted continuously for five years in Jiyi Township, Qingxu County, tomato and zucchini have been planted continuously for 6 years in Taigu County, Shandong Province The Sunji Street Office of Shouguang City has used bio-organic fertilizers to improve the salinized soil of the protected land by using bio-organic fertilizers for cucumbers and other crops that have been planted continuously for 12 years. The number of microorganisms increased sharply, bacillus increased by 50.6%, actinomycetes increased by 35.5%, nitrogen in the soil, especially nitrate nitrogen, was utilized or transformed; the degree of soil salinization was significantly reduced; vegetable growth, yield, quality, and disease resistance , growth period are better than the untreated plots with the same price. Soil salinity d...

Abstract

The invention relates to a biological organic fertilizer produced by performing microbial fermentation on lignite, vinegar residues, sawdust (straw), shale and the like and a preparation method thereof. The biological organic fertilizer comprises the following components in percentage by mass: 5 to 10 percent of lignite, 50 to 65 percent of vinegar residues, 20 to 25 percent of sawdust (straw), 8 to 10 percent of shale, 1 to 2 percent of magnesium sulfate, 0.5 to 1 percent of zinc sulfate, 0.5 to 1 percent of borax and 0.1 to 0.2 percent of microbial strain. The method comprises the following steps of: selection of microorganisms, activation, first-level amplification, second-level amplification, third-level amplification, mixing, fermentation, turning, obtaining of finished products, low-temperature drying, detection, metering and packaging. After the biological organic fertilizer is applied to protected land, organic matters and humus contained in the biological organic fertilizer can adsorb and fix cations in a free state in soil, the concentration of soil solution and the harm of salinization are reduced, the vegetable growth (harvest) period is prolonged by 10 days, yield is increased by 8.5 to 22.6 percent, morbidity is reduced by 30.3 to 56.3 percent, and the content of nitrate is reduced by 20.5 to 27.8 percent.

Description

technical field [0001] The invention belongs to a microbial fertilizer, in particular to a bio-organic fertilizer for preventing soil salinization in protected areas and a preparation method thereof. Background technique [0002] my country is one of the countries with the largest protected area planting area in the world. Soil salinization in protected areas is also known as secondary soil salinization. With the extension of planting time, the damage becomes more and more serious. It is mainly manifested in the unstretched roots of crops such as vegetables in protected areas, brown or dark brown, and poor absorption capacity; Yellowing of stems and leaves, shrinkage, dry leaf edge (burnt edge) or deformity, reduced yield, poor fertilizer effect, and the effect of topdressing chemical fertilizers is not as obvious as that of irrigation; quality reduction; poor stress resistance, etc., seriously affect the income of protected areas . The soil salt concentration in protected...
