Description
Technical field
The present invention relates to the fertilizer field in agricultural application, particularly a kind of long-acting added-acting slow release fertilizer.
Background technology
chemical fertilizer is the grain of grain.According to Food and Argriculture OrganizationFAO's statistics, irrigating, chemical fertilizer, seed, agricultural chemicals, plastic sheeting for farm use, agricultural machinery, and in the draught animal seven multi-form agriculture Yield components, the contribution rate of chemical fertilizer accounts for 40%-60%.But along with the continuous increase of fertilizer application amount, fertilizer produces to be thrown than being downward trend day by day.From 1984-1994, the usage quantity of Chinese chemical fertilizer increased by 90.7%, and grain yield has only increased by 9.1%, and the low and diminishing returns of the utilization ratio of chemical fertilizer has greatly restricted agriculture development, has wasted resource, has polluted again environment.Improving chemical fertilizer utilization ratio becomes various countries Agricultural Scientist's important topic, and the appearance of efficient long-acting Synergistic slow release fertilizer has brought a deepgoing revolution to the application of chemical fertilizer.
China's chemical fertilizer utilization ratio is lower, when the utilization ratio of quaternary nitrogen is only 30%-35%, and the utilization ratio 10%-25% of phosphorus, the utilization ratio 35%-50% of potassium, the comprehensive average low 15%-20% in more developed country, only therefore nitrogenous fertilizer just lose and reach 9,000,000 tons of left and right every year.Measure according to the Chinese Academy of Agricultural Sciences's whole nation chemical fertilizer net; Nineteen fifty-two-2002 year, the chemical fertilizer return rate of China is by 1; 33 drop to 1; 1, also decline with 0.34% speed every year.Use chemical fertilizer to increase production the contradiction but not increasing income more and more outstanding.
The contradiction that chemical fertilizer dissolves fast and crop slowly absorbs, causes a large amount of nutrients by with water leaching loss, transforms to volatilize and physics and chemistry is fixed; Farmers' cultural quality is low, and area is little.And disperse, it is real that the complicated and mechanization degree of planting system is low etc., makes agricultural science and technology service be difficult to put in place; Peasant's time and efforts costing a lot of money in agronomy operation topdressing etc. of being unwilling, has also limited the performance of fertilizer efficiency.
long-acting added-acting slow release fertilizer nutrient, along with the uptake rate of crop discharges, can reduce loss effectively, reaches saving, volume increase, synergy, convenient, the multiple targets such as environmental protection, realize agriculture Sustainable development, thoroughly change waste, poor efficiency, arduous, all drawbacks of the traditional fertilizations such as pollution.The application of long-acting added-acting slow release fertilizer is simple, is particularly suitable for China's actual conditions, is the only way of 21 century China's chemical fertilizer development.
Summary of the invention
The object of the invention is to overcome prior art deficiency, common fertilizer fertilizer efficiency period is short, and nutrient proportioning is unreasonable, and nutrient supply is science not, more unbalanced, and special nitrogenous fertilizer contradiction is more outstanding.The object of the present invention is to provide a kind of long-acting added-acting slow release fertilizer and preparation method thereof.
The present invention, by special process, adds urease inhibitor or nitrification inhibitor by organic matter and specific microorganism, and after the granulation of poly-aspartic-acid low temperature, by a certain percentage by nitrogen, phosphorus, three kinds of nutrients of potassium are made by blending method.By crop yield level, regulation of fertilizer requirement and soil nutrient content scientific matching.
for achieving the above object, the technical solution used in the present invention is as follows;
long-acting added-acting slow release fertilizer of the present invention, mainly by nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, bacteria agent, urease inhibitor, nitrification inhibitor, poly-aspartic-acid composition, by weight percentage, nitrogenous fertilizer accounts for 10-60%; Phosphate fertilizer accounts for 10-60%; Potash fertilizer accounts for 10-60%; The agent of organic-biological Recompounded multielement accounts for 5-50%; [wherein bacteria agent accounts for 6-8%; Liquid-containing binder accounts for 3-5%; Stopping composition accounts for 10-20%; Feces of livestock and poultry or humic acids account for 50-80%; Urease inhibitor accounts for 0.1-0.15%; Nitrification inhibitor accounts for 0.15-0.2%; Poly-aspartic-acid accounts for 6-20%].
Preparation method; First by bacteria agent, liquid-containing binder, stopping composition, feces of livestock and poultry or humic acids, urease inhibitor, nitrification inhibitor, poly-aspartic-acid mixes by certain weight ratio, by the granulation of special process low temperature, obtain the agent of granular organic-biological Recompounded multielement, by particulate state nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and the agent of particulate state organic-biological Recompounded multielement join by weight automatic gauge and puddle in equipment, puddle evenly, obtain finished product after packing.
The present invention has advantages of;
Technique of the present invention is simple, easily implements, and raw material abundance, selected formula material is pollution-free to soil and crop, noresidue.
The present invention is according to crop nutrient uptake feature, and balanced release, reaches quick-acting, synergy, and long-acting slow-release, meets crop growth phase nutritional need.Increase crop yield 10-30%. with common fertilizer ratio
Fertilizer efficiency period of the present invention can reach 110-120 days, exempts to topdress, and saves labor force.Can select different ingredients according to different soils and crop regulation of fertilizer requirement, reach increasing both production and income.
