Description
Technical field
It take IBDU as the slow release fertilizer of coating material that the present invention is specifically related to a kind of, belongs to control and releases fertilizer technology field.
Background technology
Owing to conventional fertilizers brings disadvantageous effect to ecotope, new-type fertilizer is all being researched and developed energetically to improve utilization rate of fertilizer in countries in the world, extends fertilizer efficiency, and prevents nutrient loss and contaminate environment. In recent years, the research and development of domestic sustained-controll-release fertiliser and production development are very fast, and particularly the development of coating slow-release or control-release fertilizer is advanced by leaps and bounds especially, and coated with resin, sulphur dressing, the product such as sulfur and resin coated emerge in an endless stream. And these coating material be mostly be difficult to degrade, sulphur that the Plastic Resin of cost height contaminated soil and a large amount of use easily make soil acidification.
IBDU (IBDU) is abroad as one of turnout conventional slow release long-acting fertilizer chemical slow release fertilizer being acknowledged as most environmental protection being only second to urea formaldehyde. IBDU (IBDU) is the condensation product of isobutyric aldehyde and urea reaction, decomposes release nitrogen element by soil microorganisms, and nitrogen utilization efficiency reaches as high as more than 90%. Releasing mechanism is that the IBDU of microsolubility is hydrolyzed into urea, and the latter is being converted into ammonium ion and changes into nitrate radical for plant growth by soil microorganisms effect and provides nutrition.Because of its solubleness low (being only the thousandth of urea), changing the feature of the easy moisture and deteriorate of urea, release rate is minimum by the impact of temperature, it is easy to regulate and release rate that prediction is fertile, and salt index is minimum in all chemical fertilizer especially, plant of can not burning. In recent years according to Japanese, German etc., this kind of condenses also has and promotes Zinc fractions crumb structure, prevents the performance desertifying and increasing crop root penetration power.
Chinese patent CN101759481A (application number 200910230286.1) discloses a kind of high-tower slow-release compound fertilizer and its preparation method. It take IBDU as sustained-release matrix, adopts the inner slow release method of fertilizer core, not coating process. Although utilization rate of fertilizer is improved; production cost reduces, and protects ecotope, but can not ensure during fertilising that can not produce to burn root burns kind of a burn seedlings phenomenon; and the rate of release of fertilizer can not fully adapt to plant growth early stage fertilizer requirement little, the characteristic that later stage fertilizer requirement is big.
Summary of the invention
It is an object of the invention to provide a kind of take IBDU as the slow release fertilizer of coating material; crop can not be burnt root burn seedlings and can be met the demand of crop at each growing stage nutrient by this slow release fertilizer applied once; time and labour saving is laborsaving; decrease the losses such as the pouring mistake of fertilizer nutrient in soil, volatilization; improve utilization rate of fertilizer, the low cost preserved the ecological environment again, free of contamination slow/controlled release compound manure.
