Description
Technical field
The present invention relates to a kind of fertilizer, concrete, relate to a kind of slow release fertilizer containing chitin and preparation method thereof.
Background technology
Fertilizer widespread use in the grains in field such as agricultural, forestry and the planting process of cash crop.The utilization ratio of existing organic fertilizer or compound manure is generally on the low side, and nitrogen is 30-35%, and phosphorus is 10-20%, and potassium is 30-35%.In recent years, due to the frequent use of chemical fertilizer, agricultural chemicals, upset the distribution of Soil Microorganism, useful bacterium becomes fewer and feweri, causes increasingly sharpening of disease and pest, natural environment deterioration.Meanwhile, because chemical fertilizer, using in a large number of agricultural chemicals also produce serious key to human body.In addition, excessive the using of chemical fertilizer not only suppresses plant growth, and unnecessary fertilizer flows into water body, also can cause the body eutrophication of rivers and lakes, polluted water environment.Therefore, improve utilization rate of fertilizer, alleviate fertilizer pollution, develop sustainable, that high-efficiency agriculture is needs attention problem.
China's crust aboundresources, cultivation, the amount of finish of Crustacean are huge, have a large amount of processing wastes simultaneously, and only crab, shrimp waste reach more than 6000 tons every year, and in Crustacean processing waste, chitin (Chitin) content is up to 20 ~ 25%.At present, it is found that chitin and derivative thereof have many premium propertiess, purposes is very extensive, has application in industries such as medicine, agricultural, environmental protection, food, weaving, printing and dyeing, plastics, color films.In recent years, chitin is increasingly extensive in application agriculturally: as new plant growth regulator, can excite seed germination, promotes plant growth, increase yield, improves quality; As soil improvement agent, can soil microflora be changed, promote actinomycetes and the growth of some other beneficial microorganism in soil, suppress the growth of pathogenic bacteria in soil and breeding; As Plant diseases resistance inductor, can the reaction of inducing plant self-defence, produce the resistance of wide spectrum, suppress the growth of various plants pathogenic micro-organism.Therefore, the fertilizer being added with chitin can improve soil microorganisms structure, improves utilization rate of fertilizer, increases crop yield.
Existing slow release fertilizer is mainly divided into chemical combination type, Envelope type and mixed type three major types.Wherein enveloped slow release fertilizer is mainly developed in China, has that cost is low, the simple feature of manufacturing process, is applicable to China's national situation.Although Envelope type fertilizer has the incomparable advantage of common fertilizer, still there is limitation from its application of present stage and exploitation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of slow release fertilizer containing chitin.Described fertilizer is rationally composite by the nutritive substances such as chitin, organic matter, humic acid, macroelement, while meeting crop growth needs, effectively can improve physico-chemical property and the micro-flora of soil, and slow releasing function is played to nitrogen phosphorus boron fertilizer, prevent fertilizer loss, remarkable enhancing fertilizer efficiency, improves the utilization ratio of fertilizer.
The present invention is achieved by the following technical programs.
The invention provides a kind of slow release fertilizer containing chitin, described fertilizer contains each component of following parts by weight: chitin 10-45 part, nitrogenous fertilizer 5-15 part, phosphate fertilizer 12-22 part, boron fertilizer 3-9 part, humic acid 5-16 part, zinc sulfate 0.5-2.5 part, magnesium sulfate 1-3 part, ferrous sulfate 0.5-2.5 part, organic 11-17 part is attapulgite modified or/and wilkinite 30-44 part.
Described chitin can change soil microflora, promotes actinomycetes and the growth of some other beneficial microorganism in soil, suppresses the growth of pathogenic bacteria in soil and breeding simultaneously.In addition, chitin can excite seed germination, promotes plant growth, increases crop yield.Described humic acid is the organic carrier that has good biological activity, multiple functional group is formed, and it has very large capacitive, can combine with many kinds of substance.Humic acid has certain effect to soil improvement, can promote the formation of soil agreegate, grows create good conditions for plant root growth.Described organic matter not only can provide nutrient for soil, also has the fertilizer-preserving ability and shock-absorbing capacity that improve soil.Chitin, humic acid and organic matter mix outside fertilizer such as being wrapped in nitrogen phosphorus boron fertilizer by the present invention according to a certain percentage, facilitate the synergy of three, while meeting crop growth needs, effectively can improve physico-chemical property and the micro-flora of soil, and slow releasing function is played to nitrogen phosphorus boron fertilizer, prevent fertilizer loss, significantly strengthen fertilizer efficiency, improve the utilization ratio of fertilizer.
Can realize the dual purpose reducing fertilizer loss, improve utilization rate of fertilizer and improvement soil, preferably, described chitin is for being crushed to 40-60 object chitin powder.
Preferably, described nitrogenous fertilizer is one or more in urea, ammonium nitrate or ammonium sulfate.
Preferably, described phosphate fertilizer is one or more in Ureaphil, phosphoric acid or monoammonium phosphate, diammonium phosphate.
Preferably, described boron fertilizer is one or more in four water eight Sodium Tetraboratees, borax, boric acid or liquid boron.
