Abstract

The invention provides a slow release compound fertilizer applicable to plantation of tobacco. 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 by taking compound fertilizer particles as the fertilizer core, then performing coating and dusting powder treatment. The compound fertilizer particles are prepared from the following raw materials by mass: 20 to 45 parts of urea, 10 to 20 parts of ammonium sulfate, 20 to 40 parts of potassium sulfate, 10 to 30 parts of a mixed phosphate fertilizer, 0.1 to 0.5 part of a zinc, copper, boron and molybdenum additive, 6 to 12 parts of a granulating auxiliary 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 the mixed phosphate fertilizer; (3) preparation of the compound fertilizer particles; (4) coating with stearic acid; (5) powder spreading of a modified zeolite powder material; and (6) screening. The invention provides the slow release compound fertilizer applicable to plantation of tobacco which has overall nutrients and excellent slow releasing performance, not only enables a high fertilizer utilization rate to be obtained, but also improves both output and quality of tobacco.

Description

Be suitable for the slow-release compound fertilizer that tobacco planting is used
Technical field
The present invention is a kind of slow-release compound fertilizer being suitable for tobacco planting and using.Belong to the multiple fertilizer containing the material affecting urea nitrification in soil and the mixture without special fertilizer efficiency component.
Background technology
Tobacco is important food crop and cash crop, and its output and cultivated area have obvious ascendant trend.Critical role is occupied in the people's livelihood and national economy.Tobacco economic benefit depends on output and the production cost of tobacco leaf.The target of the quality of tobacco leaf people's unremitting pursue especially.Effectively utilize limited land resources, the yield and quality improving tobacco plants is the direction that people make great efforts.
Tobacco typically likes potassium crop, and the potassium element that its necessary for growth absorbs is in the majority, and potassium element has the laudatory title of cigarette quality element.Application of potash fertilizer can improve the color of tobacco leaf, improves its quality grade, improves the security of the incendivity of cigarette, sucking property and cigarette products.Therefore, the height of preservative water preperation is one of important indicator evaluating quality of tobacco quality.In addition, the growth of tobacco also need appropriate, enough nitrogen, phosphatic manure , He ?, the trace element such as copper, boron, molybdenum.There is the prejudice blindly improving potash fertilizer in tobacco of the prior art.
The high-quality nitrogenous fertilizer that urea is nitrogenous height, fertilizer efficiency is fast, consumption is large.But, urea in use, easily run off by approach such as volatilization, leaching, decomposition and runoffs, cause fertilizer efficiency utilization ratio not high, according to statistics, this season utilization ratio only has about 30%, and this not only causes the waste of chemical fertilizer, and for the environment that the mankind such as air, water body soil depend on for existence.
In order to solve the problems of the technologies described above, at present, sulphur and the various macromolecule resin of adopting carries out coating process to urea more both at home and abroad.Or add uric acid inhibitor and nitrification inhibitor; Utilize the high molecular polymer such as cyclochloride resin, acrylic resin material coated even multilayer coating or severally comprise the composition such as fertiliser granulates mixing sustained-release and controlled release fertilizer; Coated fertilizer is difficult to, in degraded in soil, work the mischief to edatope.And complex process, manufacturing cost is high, contaminate environment.
The Chinese Patent Application No. 201110021688.8 " biodegradable coated urea " of Shikefeng Chemical Industry Co., Ltd.'s application successfully solves the above problem of urea nitrogenous fertilizer existence, the stearic acid that can degrade under soil microorganisms effect of utilization is as the coated fertilizer of nitrogenous fertilizer urea, provide a kind of coated fertilizer biodegradable, pollution-free, the biodegradable coated urea product of the utilization ratio of fertilizer can be improved again.But it is a kind of high-quality nitrogenous fertilizer, and nutritive ingredient is single, can not as the slow release fertilizer being suitable for tobacco planting and using.
Phosphorus is the important composition element of cytoplasmic biomolecule, is also the requisite a kind of element of plant-growth.Phosphatic rock is the main raw mineral materials manufacturing phosphate fertilizer and extract phosphorus and compound thereof; But manufacture phosphate fertilizer and require phosphatic rock P 2o 5>=28%; Extract the phosphatic rock P of phosphorus and compound requirement thereof 2o 5content higher.
And along with the development of phosphorus chemical product and Phosphate Fertilizer Industry, ground phosphate rock requirement increases sharply, and higher-grade phosphate rock resource is deficient.The mode of production only depending on rich phosphorus ore can not meet the demands.In this case, the exploitation of the phosphatic rock resource that grade is not high, no matter for economizing on resources, or protection of the environment is all significant.
In sum, fertilizer special for tobacco material of the prior art exists following not enough:
1.. multilayer coating, complex manufacturing, investment is large, production cost is high.
2. coated fertilizer is difficult to degraded, and life-time service can bring negative impact to soil; Even soil is polluted, affect the quality of agricultural-food.
3. the main nutrient elements proportioning in fertilizer is not mated for the demand in tobacco growing each stage, and fertilizer efficiency utilization ratio is low.
4. lack necessary trace element, not comprehensive nutrition, affects output increased.
5. be suitable for the slow-release compound fertilizer that tobacco planting is used, the fertilizer improving tobacco production and quality is also rare.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art; overcome traditional prejudice, reduce production cost, useful environment is protected; and a kind of comprehensive nutrition is provided; sustained release performance is excellent; fully can meet the demand of tobacco to nutrient; play the effect of fertilizer to greatest extent, that can improve that tobacco production can improve again its quality is suitable for the multiple and fertilizer of slowly-releasing that tobacco planting uses.
