Description
Technical field
The present invention relates to slow controlled release nitrogenous fertilizer or slow controlled release compound (closing) fertilizer, specifically a kind of slow control releasing fertilizer of containing nitrogen that adds new nitrification DMP and preparation method thereof.
Background technology
Nitrogenous fertilizer is the important production means in the agriculture production, and enormous function has been brought into play in the development that promotes agriculture production.But because the nitrogen singularity and the unreasonable of nitrogenous fertilizer that transform in soil are used, the utilization ratio of nitrogenous fertilizer is very low, generally has only about 30%, in some vegetables intensive cultivation districts, and utilization rate of nitrogen fertilizer even below 10%.This not only caused economically with resource on huge waste, and environment and the food safety that we mankind depend on for existence constituted serious threat.In China Council for International Cooperation on Environment and Development's annual meeting in 2004, the expert of China and foreign countries is consistent point out Chinese farmers abuse chemical fertilizer and agricultural chemicals (polluted by nitrogen that especially causes) serious harm to HUMAN HEALTH and environmental quality, China is excessive to use chemical fertilizer and agricultural chemicals has arrived the limit, and requirement should improve the popularity of science and technology, the environmental legislation of being correlated with as early as possible.And produce coated fertilizer and stabile fertilizer by industrial approach, the slowly-releasing of realization nitrogenous fertilizer, long-acting not only can improve utilization rate of nitrogen fertilizer, and can reduce fertilizer application frequency, reduces labour intensity, alleviates environmental pollution, improves quality of agricultural product.This walks the sustainable agriculture development road and has important practical significance undoubtedly for the development that promotes China's pollution-less agriculture, green agriculture.
Realize the efficient utilization of nitrogenous fertilizer by adding urease inhibitor and nitrification inhibitor regulation and control nitrogen being converted in soil; it is a nitrogenous fertilizer administrative skill that development potentiality is arranged very much; and there is the expert to foretell; in the future, inhibitor be applied in the effect of bringing into play in the environment protection will be greater than its contribution in world's foodstuffs production.Compare with coating controlled-release fertilizer, the stabile fertilizer that adds inhibitor is because its application effect is more remarkable, and production technique is simple, and production cost is relatively low, therefore, is subjected to the extensive attention of domestic and international research field and fertilizer industry always.Especially in whole nitrogen fertilizers of on our times, using, the quantity of ammonium fertilizer and product ammonium fertilizer has accounted for more than 90%, use the oxidation process that nitrification inhibitor delays soil ammonium-state, with the leaching loss of minimizing nitric nitrogen and the discharging of greenhouse gases, improve utilization rate of nitrogen fertilizer, will have more importantly meaning.But up to the present, really the nitrification inhibitor kind of large-scale application is seldom aborning.The inhibiting nitrification effect of nitrification inhibitor Dyhard RU 100 (DCD) that occupies dominant position at home and abroad is better, but exists the shortcoming that self is difficult to overcome, as water-soluble higher, and easy leaching; The inhibiting nitrification rate is lower, and amount of application is bigger; During repetitive administration, because the influence of the microflora that forms causes its degradation rate to be accelerated, the transformation period shortens; Use improper or amount of application when excessive, cause easily murder by poisoning of plant even residual etc. in agricultural-food.According to the literature, the nitrification inhibitor DMPP effect of German BASF AG up-to-date exploitation in nearly 2 years is more remarkable, but also very limited in the experimental study of China, and if be introduced into China, cost may also can become a main limiting factor.Above various reasons has seriously restricted production and the large-scale promotion application by the sustained-controll-release fertiliser of biochemical route regulation and control nitrogen transformation.
