The microbial organic fertilizer is prepared by taking algae, straws and manure as raw materials by means of a composite microbial two-step fermentation process. The microbial organic fertilizer has functions of microbial fertilizer, organic fertilizer and algae fertilizer and is rich in algae functional active ingredient and a great amount of probiotics and capable of effectively adjusting balance of microorganisms in soil, decomposing organic or inorganic components such as organic matters, minerals and the like in the soil, eliminating caking, sanding, salting and the like of the soil caused by abused application of chemical fertilizer, effectively improving the soil, improving the stress resistance of crops and improving the productivity of crops; furthermore, the microbial organic fertilizer can promote the release of organic matters in the soil, improve the physical and chemical structure of the salted soil, improve the clustering and permeation performance of the soil, improve the fertility of the soil and improve the grain productivity increasing capacity of the saline-alkali soil and is an excellent saline-alkali soil improvement agent and crop growth accelerator.
Description
Technical field
The present invention relates to a kind of microorganism organic fertilizer with alkaline land improving effect, belong to fertilizer manufacture field.
Background technology
Since reform and opening-up, the rapid economic development of China, the standard of living of people improves day by day, but is also faced with the phenomenon in short supply of resource simultaneously, and land resources is in short supply is exactly one of them.Soil falls into disuse, soil pollution is all phenomenon very serious at present.Therefore, protect farmland, open up wasteland and fall into disuse the emphasis that soil is resources development and utilization from now on.The current soil salinization is very serious, brings very large impact, be unfavorable for the plantation of plant to agricultural.Because the physics and chemistry function of salinization soil is poor, cause the microorganism active in soil very low, plant can not grow normally, therefore brings disadvantageous effect to agricultural resource.Whole world salinization soil area about 8,970,000 square kilometres, accounts for 6.5% of world land area, accounts for 39% of the arid biogeographic zone total area.China's salinization soil area about has more than 20 ten thousand square kilometres, accounts for 2.1% of territory total area.In the arable land of 100,000,000 square kilometres, China, about have the soil of 10% to belong to salinization soil, in addition, also have the salt wasteland of more than 2000 hectare, wherein major part is not utilized by the reclamation of wasteland.How opening up wasteland and to utilize these salinization soils, expanding cultivated area, increasing national income, is one of major issue during current agricultural is produced.Current national government and scientific researcher all pay attention to the reparation to salinization soil, actively develop the research of each side and reasonably develop, making it to become land resources effectively.
Commonly use the plant improvement method etc. in washing salinity by irrigation, deep ploughing soil moved in improve the original, physico-chemical processes and agricultural for salinization soil, these can both play and improve soil in certain degree, promote the effect of plant development.But utilize cost high, easily produce secondary pollution.Microbial fertilizer is improved products more novel at present, more effectively comprehensively can send out and utilize salinization soil.A lot of experts and scholars approve the improved effect of microorganism.Not only cost is low for it, and the advantage such as non-secondary pollution.But still there is the drawbacks such as improvement cost is high, effect is poor in using microbe fertilizer improving salinization soil at present, not yet realizes large-scale promotion application.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of microorganism organic fertilizer with alkaline land improving effect, promote the release of soil with organic matter, improve the physicochemical structure of salinization soil, increase soil agreegate and perviousness, improve fertile soil degree, improve the increases in grain production ability in saltings.
