Abstract
The invention provides a slow release compound fertilizer applicable to plantation of vegetable. The slow release compound fertilizer is a mixture of a plurality of fertilizers containing substances which exert influence on nitrification of urea in soil and components with no special fertilizer efficiency and is prepared from the following raw materials by mass: 30 to 50 parts of urea, 8 to 22 parts of ammonium sulfate, 22 to 45 parts of potassium sulfate, 7 to 12 parts of a granulating agent and a proper amount of water. A preparation method for the slow release compound fertilizer comprises the following steps: (1) preparation of a compound of a potash fertilizer and a nitrogen fertilizer; (2) preparation of mixed particles of the components of the compound fertilizer; (3) coating with stearic acid; (4) powder spreading of a modified zeolite powder material; and (5) screening, metering and quality inspection. The slow release compound fertilizer applicable to plantation of vegetable provided by the invention can improve both output and quality of vegetable, increase raphaninin in vegetable and reduce enrichment of heavy metals in vegetable and the content of nitrate in vegetable.
Description
Technical field
The present invention is a kind of slow-release compound fertilizer that growing vegetables is used that is suitable for.The multiple fertilizer that belongs to the material that contains influential urea nitrification in soil and mixture without special fertilizer efficiency component.
Background technology
Vegetables contain abundant VITAMIN, and food ingestion is large in daily life, lay equal stress on grain in the human diet structure, and its output and cultivated area have obvious ascendant trend.In the people's livelihood and national economy, occupy critical role.The vegetables economic benefit depends on output and the production cost of vegetables.The target of the high-quality especially people unremitting pursue of vegetables.Effectively utilize the Limited Land resource, the yield and quality that improves vegetable crop is the direction that people make great efforts.
Vegetables are to need the more crop of nitrogenous fertilizer, and the nitrogen element that its necessary for growth absorbs is in the majority, and nitrogenous fertilizer is to improving the vegetable crop successful.This is that still, the enrichment of the nitrate in the vegetables constitutes a threat to HUMAN HEALTH because vegetables are happiness nitre crop simultaneously.Studies show that, excess ingestion nitrate, nitrite are one of inducible factors of the diseases such as human cancer.Nitrate in the vegetables is the important sources of human picked-up nitrate.So, can satisfy vegetables to the demand of nitrogen element, can reduce again nitrate in the vegetables and the content of nitrite, also be the target that fertilizer industry is pursued.
In addition, research finds that sulforaphen has extremely strong promotion carcinogens degraded, the effect that anticancer generates.And find that sulforaphen is one of active skull cap components that antitumour activity is the strongest in vegetables.At present, utilize chemical synthesis process to prepare sulforaphen and realize that industrialization generates, also be difficult to realize.Therefore, the method for the sulforaphen in the raising vegetables is that people expect.
The high-quality nitrogenous fertilizer that urea is nitrogenous height, fertilizer efficiency is fast, consumption is large.But urea in use easily runs off by approach such as volatilization, leaching, decomposition and runoffs, causes the fertilizer efficiency utilization ratio not high, and this has not only caused the waste of chemical fertilizer, and the environment of depending on for existence for mankind such as atmosphere, water body soil.
In order to solve the problems of the technologies described above, at present, sulphur and the various macromolecule resins of adopting carry out the coating processing to urea more both at home and abroad.Perhaps add uric acid inhibitor and nitrification inhibitor; Utilize the material coated even multilayer coating of the high molecular polymers such as cyclochloride resin, acrylic resin or severally comprise that fertiliser granulates mixing etc. forms sustained-release and controlled release fertilizer; Coated fertilizer is difficult in degraded in soil edatope be worked the mischief.And complex process, manufacturing cost is high, contaminate environment.
Chinese patent application number 201110021688.8 " biodegradable coated ureas " of Shikefeng Chemical Industry Co., Ltd.'s application have successfully solved the above problem that urea nitrogenous fertilizer exists, the stearic acid that utilization can be degraded under the soil microorganisms effect is as the coated fertilizer of nitrogenous fertilizer urea, provide a kind of coated fertilizer biodegradable, pollution-free, can improve again the biodegradable coated urea product of the utilization ratio of fertilizer.But it is a kind of high-quality nitrogenous fertilizer, and nutritive ingredient is single, can not be as the slow release fertilizer that is suitable for growing vegetables and uses.
In sum, there is following deficiency in vegetable fertilizer of the prior art:
1.. the multilayer coating, complex manufacturing, investment is large, production cost is high.
2. coated fertilizer hard degradation, life-time service can bring negative impact to soil; Even soil polluted, affect the quality of agricultural-food.
3. improve sulforaphen, the enrichment of reduction heavy metal in vegetables, the fertilizer of the nitrate content in the reduction vegetables in the vegetables, there is not yet report.
5. can improve the slow-release compound fertilizer that growing vegetables is used that is suitable for that vegetable crop can improve again quality of vegetable, also rare.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art, can improve the slow-release compound fertilizer that growing vegetables is used that is suitable for that vegetable crop can improve quality of vegetable and provide a kind of.Have the sulforaphen, the enrichment of reduction heavy metal in vegetables, the effect of the nitrate content in the reduction vegetables that improve in the vegetables concurrently,
Purpose of the present invention can reach by following measure:
Of the present inventionly be suitable for the compound manure that growing vegetables is used, it is characterized in that being made by following raw material according to the mass fraction meter:
Described granulation aid is mixed by the bauxitic clay powder of 60%～80% wilkinite and 40%～20% and is formed;
Its preparation method comprises the steps:
