Description
Technical field
The present invention is a preparation method who grows tobacco special-purpose sustained-release long-acting compound fertilizer.The multiple fertilizer that belongs to the material that contains influential urea nitrification in soil and 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.Occupy critical role in the people's livelihood and national economy.The tobacco economic benefit depends on output and the production cost of tobacco leaf.The quality of tobacco leaf is the target of people's unremitting pursue especially.Effectively utilize the Limited Land resource, the yield and quality that improves the tobacco crop is the direction that people make great efforts.
Tobacco is typically to like the 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 incendivity, sucking property and the cigarette products of cigarette.Therefore, in tobacco leaf, the height of potassium content is one of important indicator of estimating the quality of tobacco quality.In addition, the growth of tobacco also needs in right amount, the nitrogen of capacity, phosphatic manure ， He ?, the trace element such as copper, boron, molybdenum.There is the prejudice that blindly improves 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 the fertilizer efficiency utilization ratio not high, according to statistics, the this season utilization ratio only has 30% left and right, 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 high molecular polymers such as cyclochloride resin, acrylic resin material coated even multilayer coating 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 tobacco planting and uses.
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 of making phosphate fertilizer and extracting phosphorus and compound thereof; But make phosphate fertilizer and require phosphatic rock P
2O
5〉=28%; Extract the phosphatic rock P that phosphorus and compound thereof require
2O
5Content higher.
And along with the development of phosphorus chemical product and Phosphate Fertilizer Industry, the ground phosphate rock requirement increases sharply, and the higher-grade phosphate rock resource is deficient.The mode of production that only depends 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, there is following deficiency in fertilizer special for tobacco material 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 is polluted, affect the quality of agricultural-food.
3. the main nutrient elements proportioning in fertilizer is not mated for the demand in each stage of tobacco growing, and the fertilizer efficiency utilization ratio is low.
4. lack necessary trace element, the hypotrophy face affects output and improves.
5. can improve simultaneously the preparation method of sustained-release long-acting compound fertilizer of the tobacco special use of tobacco production and quality, 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 costs, useful environment protection; and provide a kind of comprehensive nutrition; sustained release performance is excellent; can fully satisfy tobacco to the demand of nutrient; bring into play to greatest extent the effect of fertilizer, 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.
