Abstract
The invention relates to a controlled-release base fertilizer specially used for vegetables. The fertilizer is prepared by evenly mixing 3-5% reaction film formation polymer coated urea, urea, diammonium phosphate, potassium sulfate and calcium superphosphate. The controlled-release base fertilizer is simple in technology; due to the nutrient releasing characteristic of the reaction film formation polymer coated controlled-release fertilizer and the nutrient absorbing law of the vegetables, the single controlled-release fertilizers with different release periods and partial quick-acting fertilizers are compounded with each other; the balanced nutrient needed by the vegetables can be continuously supplied in a synchronous way, so that the utilization rate of the fertilizer is improved; and the crop resistance is improved, the photosynthetic efficiency is increased, the diseases and insect pests of the vegetables are reduced, and the environmental pollution problem caused by nitrate nitrogen leaching and volatile matter can be solved. The controlled-release base fertilizer improves the service sustainability of the vegetable field, has good effects proved by field experiments, and has better economic and social benefits.
Description
Technical field
The invention belongs to the fertilizer special for vegetable field, relate to a kind of Controlled Release Fertilizer, specifically a kind of dedicated release-controlled base manure of vegetables that contains controlled release nitrogen.
Background technology
China is maximum in the world vegetables producing country and country of consumption.Along with the enforcement of " vegetable basket " engineering, the Development of Vegetable Industry of China is swift and violent in recent years, in Chinese Economy Development, particularly occupies an important position in the agricultural restructuring process.Sown area is by nearly 100,000,000 mu of about 2.3 hundred million mus of being increased to 2010 of nineteen ninety.The vegetables commodity rate is high, and comparative effectiveness is high, is one of important sources of farmers' income.
Along with growth in the living standard, the demand of vegetables has turned to the demand of matter from the demand of amount, vegetable grower's custom is once made base fertilizer with chemical fertilizer and is manured into soil, because the characteristics such as the temperature in facility vegetable plot is high, irrigation quantity is large, need in a large number fertile periods to vegetables are real, chemical fertilizer decompose already volatilization or with the water leaching to deep subsoil, caused waste and environmental pollution, and contain a large amount of chemical fertilizer in the base manure and also easily burn seedling, thereby affect the development of vegetables industry.
Release and release control fertilizer is to realize that nutrient discharges the new-type fertilizer synchronous with Crop, can control according to the growth demand of crop burst size and the release rate of fertilizer nutrient, reaches the efficient purpose of volume increase.If but it is high separately it to be used in Vegetables cost, the peasant is difficult for accepting, and is unfavorable for using.
Summary of the invention
The purpose of this invention is to provide the dedicated release-controlled base manure of a kind of vegetables, utilization is reacted into the Nutrient Release of membrane polymer coating controlled-release fertilizer, while is according to the law of nutritive absorption of vegetables, the single kind Controlled Release Fertilizer and the part quick-acting fertilizer that difference are discharged period carry out composite, can continue the synchronously required balanced nutrient of supply vegetables, avoided the high concentration fertilizer obstacle, improved utilization rate of fertilizer, the problem of environmental pollution of having avoided again the volatilization of nitric nitrogen leaching and ammonium nitrogen to cause, reduce vegetable insect disease, increase peasant income, through a large amount of field experiments, obtained good effect.
The technical solution adopted in the present invention:
The dedicated release-controlled base manure of a kind of vegetables is to be reacted into membrane polymer coated carbamide, urea, diammonium phosphate, vitriolate of tartar and calcium superphosphate by 3～5% to mix and make, and wherein the parts by weight of each component are by weight:
Wherein: the weight ratio of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide is: 1: 0.7～0.9: 0.9～1.1.Described 3～5% be reacted into the membrane polymer coated carbamide refer to the coating layer quality be total mass 3～5% be reacted into the membrane polymer coated carbamide, the membrane polymer coated carbamide that is reacted into by low, high two kinds of different coating layer quality consists of, and the part by weight of the two is 1:1～2.
Adopt the membrane polymer coated carbamide that is reacted into of different coating layer quality to make up, burst size and the release rate of controlled composting material nutrient make its law of nutritive absorption that meets better the vegetable growth phase, make fertility more lasting.
The described membrane polymer coated carbamide that is reacted into is that heat curing-type is reacted into the membrane polymer coated carbamide.
Described heat curing-type is reacted into that the membrane polymer coated carbamide is polyurethanes reaction film Polymer coated urea, epoxy resin is reacted into the membrane polymer coated carbamide or the alkyd resin class is reacted into the membrane polymer coated carbamide, especially refers to polyurethanes reaction film Polymer coated urea.
Among the present invention, the granulated fertilizer that the equal preferable particle size of all raw materials is 2～5 millimeters.
The preparation method of the dedicated release-controlled base manure of vegetables of the present invention: above-mentioned each raw material is put into the blending machine together by proportioning, and then abundant mixing sends mixed fertilizer into metering, wrapping machine measures, packs.Take vegetables oil and solidifying agent as main raw material, need not to add solvent, cleanliness without any pollution in the film-coated controlled release fertilizer manufacturing processed.
The application of the dedicated release-controlled base manure of vegetables of the present invention: before growing vegetables, make base manure and once apply.Fertilizing method is to spread fertilizer over the fields after plowing, earthing after the fertilising.
Further preferred, the dedicated release-controlled base manure of vegetables provided by the present invention, the parts by weight of each component are by weight:
Technique of the present invention is simple, utilization is reacted into the Nutrient Release of membrane polymer coating controlled-release fertilizer, while is according to the law of nutritive absorption of vegetables, the single kind Controlled Release Fertilizer and the part quick-acting fertilizer that difference are discharged period carry out composite, can continue the synchronously required balanced nutrient of supply vegetables, improved utilization rate of fertilizer, strengthen crop resistance, improve photosynthetic efficiency, reduce vegetable insect disease, the problem of environmental pollution of having avoided again the volatilization of nitric nitrogen leaching and ammonium nitrogen to cause improves the sustainability that use in the vegetable plot, increased peasant income, through a large amount of field experiments, obtained good effect, for the development of vegetables industry provides safeguard.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The selected material of the present invention requires: 1. fertilizer is particulate state, and good fluidity; 2. particle diameter is in 2.0～5 millimeters scopes, and various materials can be complementary; 3. more than the nutrient content index that amount of nutrients has provided above should be able to reaching.
Embodiment one
Raw material:
Above-mentioned each raw material is put into the blending machine together, and then abundant mixing sends mixed fertilizer into metering, wrapping machine measures, packs.The total nutrient of the dedicated release-controlled base manure of gained vegetables: nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are respectively 15%, 13%, 17%, are mass percent.
