Description
Technical field
The present invention is the preparation method of the sustained-release long-acting compound fertilizer of a grow wheat special use.Belong to multiple fertilizer with without the mixture of special fertilizer efficiency component.
Background technology
Wheat is important food crop and cash crop, has statistics to show, its output and cultivated area are only second to paddy rice, occupy the second place of the world.Occupy critical role in the people's livelihood and national economy.Effectively utilize the Limited Land resource, the yield and quality that improves wheat crop is people's direction of making great efforts and eternal problem.
The nutritive element that Growth of Wheat need to absorb is kind more than 20 nearly, mainly contains nitrogen, phosphorus, three kinds of macroelement of potassium; The major elements such as Calcium Magnesium Sulphur and iron, manganese, boron, copper.The trace element such as zinc, molybdenum.These nutritive elements mainly provide by soil from fertilizer.
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.
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 wheat 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 the P in phosphate fertilizer requirement phosphatic rock
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 specially for wheat 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 unreasonable, and the fertilizer efficiency utilization ratio is low.
4. lack necessary middle amount or trace element, the hypotrophy face affects the raising of output and wheat quality.
4. utilization rate of nitrogen fertilizer is low, waste resource, contaminate environment.
5. the preparation method of the sustained-release long-acting compound fertilizer of wheat special use is also rare.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art; and provide a kind of comprehensive nutrition; sustained release performance is excellent; can fully satisfy wheat to the demand of nutrient; bring into play to greatest extent the effect of fertilizer; can improve wheat yield and can improve again its quality, namely economize on resources, again the preparation method of the sustained-release long-acting compound fertilizer of the wheat special use of protection of the environment.
