Description
Technical field
The invention belongs to Crop fertilizer field, particularly a kind of microorganism fertilizer synergistic agent by thermo-responsive hydro gel controlled release and preparation method thereof.
Background technology
China is agricultural development big country, also be chemical fertilizers production maximum in the world and the country of use, year applying quantity of chemical fertilizer accounts for 35% of world's total amount, but the utilization ratio of chemical fertilizer is far below developed country, wherein utilization rate of nitrogen fertilizer be 30% ~ 35%, phosphate fertilizer this season utilization ratio 8% ~ 20%, potassium utilization rate about 50%.In order to improve fertilizer efficiency and utilization rate of fertilizer, some new-type fertilizers are applied and give birth to, as microorganism fertilizer, slow-release or control-release fertilizer, bio-fertilizer, Water soluble fertilizer etc., wherein microorganism fertilizer mainly makes farm crop obtain specific fertilizer effect by beneficial microorganism vital movement and meta-bolites thereof, and its primary efficacy is activated fertilizer nutrient, improves chemical fertilizer utilization ratio, suppresses the absorption of the objectionable impurities such as farm crop heavy metal and agricultural chemicals, improves crops quality, improves activating soil etc.Therefore, microbial fertilizer has just had chemical fertilizer, fertilizer, the multiple fertility of beneficial organism bacterium and effect, is Crop Improvement quality, the desirable fertilizer promoting agricultural production efficiency.
A large amount of beneficial microorganism vital movements that effect of microbial fertilizer mainly relies on it to contain have been come.Therefore, in microbial fertilizer, beneficial microorganism quantity and activity thereof are the principal elements affecting microorganism fertilizer efficiency.At present, China's microorganism fertilizer development is very fast, and kind constantly increases, but quality product is uneven, and effect of fertilizer is very unstable, and therefore, the Developing Extension of microorganism fertilizer is subject to certain obstruction.China Patent Publication No. CN102173925A discloses multi-element composite microbial fertilizer, it adopts the production technique optimized to carry out fermentative production by alga microbial, mushroom microorganism and forms, have that raw material is easy to get, production cost is low, stable performance, fertilizer efficiency be lasting, biological effectiveness high, to accelerate agricultural crop straw the supply of becoming thoroughly decomposed, increasing the available nutrient of soil, improve soil physico-chemical characteristic, Promoting plant growth, raising crop yield, improve quality of agricultural product aspect successful.
China Patent Publication No. 104058835A discloses a kind of high-efficiency biological source medical fertilizer and preparation method thereof, this liquid medicine fertilizer comprises microorganism species, humic acid, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, boric acid, the ammino acid liquid fertilizer fermented by fish meal, water-soluble isolating agent and plant-growth regulator, this liquid medicine fertilizer is directly sprayed onto on blade face, nutritive substance is evenly distributed, utilization ratio is high, is easy to plant Foliage Absorption.But it is fertile directly to spray this liquid medicine, beneficial organism bacterium can be made to reduce survival rate by the impact (as ultraviolet etc.) of external environment, affect fertilizer effect.
China Patent Publication No. CN103641640A discloses the active synergy microorganism fertilizer of a kind of marine alga and preparation method, with fermentation of seaweed liquid for synergy raw material, adds microorganism and is processed into.As synergistic agent, fermentation of seaweed liquid can not only promote that plant is to the absorption of nutrient, the effect of slow controlled release, coating can also be played to nutrient, for crop provides safer growing environment, promote stable crop yield, high yield, high-quality, microbial bacteria group energy decomposes the nutrient in soil, promote Crop, improvement Soil structure.
In sum, beneficial microorganism bacterial classification is mainly arranged in pairs or groups with fertilizer nutrient and is mixed by microorganism fertilizer in the market, directly be manured into soil, inappropriate fertilizer ratio can affect breeding and the activity of microbial strains on the one hand, reduces the quantity of beneficial microorganism bacterial classification; On the other hand, be directly manured into soil by microorganism fertilizer, beneficial microorganism bacterial classification directly leaks in edatope cruelly, can be subject to the impact of the environmental factorss such as illumination, temperature, moisture and cause its active reduction, affecting fertilizer efficiency.Therefore, the impact of environmental factors on microorganism fertilizer efficiency also can not be ignored, but the relevant report affected microorganism fertilizer efficiency about environmental factors is at present less, therefore, the present invention is directed to the disadvantageous effect that environmental factors produces microorganism fertilizer efficiency, propose a kind of microorganism fertilizer synergistic agent.
