Description
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of new and effective corn fertilizer and preparation method thereof.
Background technology
From the sixties in last century, the developed country such as the U.S., Japan takes up from improving the chemical fertilizers production technology, widen the new fertilizer kind, improve utilization rate of fertilizer, slowly-releasing, controlled release theory are proposed, and successfully develop series of new fertilizer, promote the progress in this field, and made utilization rate of fertilizer increase substantially.This new and high technology of release and release control fertilizer proposes new thinking and approach for solving the low difficult problem of chemical fertilizer utilization ratio.Entrust according to the United Nations Industrial Development Organization (UNIDO) that international fertilizer development center (IFDC) writes " chemical fertilizer handbook the 21 chapter release and release control fertilizer is defined as: can be called at the fertilizer that even several seasons of growth of the whole season of growth discharge plant nutrient at leisure controlled release and discharge fertilizer.The nutrient release rate of sustained-release and controlled release fertilizer can be complementary with crop crop regulation of fertilizer requirement, having specified temp releasing rule and nitrogen discharges and is subject to the impact of the complexity factors such as soil type, water content, pH value, microbial biomass less, can improve to greatest extent the fertilizer utilization rule, prevent unnecessary nutrient contaminate environment, therefore, being called as " environmental protection " fertilizer, is 21 century fertilizer industry developing direction.At present, the U.S., Japan, existing 39 producers that produce sustained-release and controlled release fertilizer in West Europe, and start late in China's research sustained-release and controlled release fertilizer aspect, in China, abuse under the present situation that chemical fertilizer problem and chemical fertilizer demand structure and quality problems are more and more outstanding, widely popularize the sustained-release and controlled release fertilizer technology, significant to the raising of level of agricultural production and environmental quality.
Corn is that the Northeast plants plant in a large number, at present main fertilizing method meets the crop needs of whole breeding time for the front single fertilization of plantation, fertilizer be take chemical fertilizer as main, most of is high nitrogen (compound manure a kind of that exempt to topdress, nitrogen content is in the 22-28% left and right, total nutrient content is in the 48-56% left and right), this class fertilizer variety and fertilizing method lack theory support, do not there is science, its direct result is nitrogen, the utilization ratio of potassium is low, and plant growth nutrient in early stage discharges fast, the growth later stage there will be nutrient wretched insufficiency phenomenon, because original composite fertilizer can not use with zinc sulfate simultaneously, search and easily can not meet the demand of corn to trace element zinc.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of new and effective corn fertilizer, be suitable for the technical requirements of different areas corn single fertilization, coincide with absorbed nitrogen by crop, suction potassium peak period, it is easy that this fertilizer has production, technical costs is low, is suitable for the characteristics of batch production.
The technical solution used in the present invention is to provide a kind of new and effective sustained-controll-release fertiliser, and this special fertilizer comprises the component that weight part is following :-20 parts, 15 parts, a film urea, two-15 parts, 10 parts, film urea, three-15 parts, 7 parts, film potash fertilizer, granular urea 15-30 part, granular potash fertilizer 7-15 part, phosphate fertilizer 20-30 part.
Preferably, a described film urea comprises the component of following weight part, 98 parts of common ureas, 2 parts of polymer resin materials.
Preferably, described two film urea comprise the component of following weight part, 97 parts of common ureas, 3 parts of polymer resin materials.
Preferably, described three film potash fertilizer comprise the component of following weight part, 98 parts of granular potash fertilizers, 2 parts of polymer resin materials.
The present invention also provides the method for preparing new and effective sustained-controll-release fertiliser, by a film urea 15-20 part, two film urea 10-15 parts, three film potash fertilizer 7-15 parts, granular urea 15-30 part, granular potash fertilizer 7-15 part, phosphate fertilizer 20-30 part is mixed, and fully stirs 15-20 minute, by the fertilizer metering mixed, packing, get final product.
The invention has the beneficial effects as follows that this fertilizer is suitable for the technical requirements of different areas corn single fertilization, with absorbed nitrogen by crop, inhale the potassium peak period and coincide, this fertilizer has to be produced easyly, and technical costs is low, is suitable for the characteristics of batch production.
