Description
Technical field
The present invention relates to a kind of Weed removal medicinal fertilizer for paddy rice and manufacture method thereof
Technical background
The research of Weed removal medicinal fertilizer, the data record sees 1964 " northeastern Japan agricultural experiment station research report " the earliest, ploughing one with this paddy is that the researcher of representative begins one's study from early 1960s and weed killer herbicide pentachlorophenol (PCP) is sneaked into fertilizer uses as base manure, reach the saving labour with it, the purpose of continuity herbicidal effect.Result of study shows, uses the NH that sneaks into PCP in the field
3Behind-N the fertilizer, can prevent NO
3-disappearance, reason is the metabolism that PCP can suppress nitrifying bacteria in the soil, and nitrification is hindered, thereby obtains PCP and fertilizer is used with, not only can keep its drug effect, and the conclusion that suppresses nitrification and the similar effect of topdressing is arranged.U.S. scientific research personnel finds prometryn energy strong inhibition nitrification and denitrification at the mid-1960s, reduces the loss of nitrogen, can also strengthen biological nitrogen fixation, so can increase the nitrogen content in the soil.Kind surplus the weed killer herbicide 300 that the beginning of the eighties, the U.S. also once proposed Gong to use with, chemical fertilizer has 5 kinds, and wherein great majority are liquid composite fertilizer.But because the researcher finds that Weed removal medicinal fertilizer Chinese medicine and fertilizer do not match, process reasons such as loaded down with trivial details, poor stability, all fail large scale application after through some research, further research report is also rare.
Before and after the eighties, scientific research departments such as China Jilin Agriculture University, Ningxia Academy of Agri-Forestry Sciences, academy of agricultural sciences, Zhejiang Province and academy of agricultural sciences, Heilungkiang have also carried out the research of relevant Weed removal medicinal fertilizer in succession.With 2,4-D weed killer herbicide and urea or superphosphate are used with as the Heilongjiang Province, find to have tangible synergy production-increasing function, particularly superphosphate the most remarkable in raising drug effect and production-increasing function, but fail to be developed into stable product.The herbicide urea of Zhejiang, the development of Ningxia two provinces adopts coating method that weed killer herbicide is wrapped in the urea granules appearance, and finds that weed killer herbicide has significant inhibitory effect to the living spore sarcina ureae of the nitrogenize bacterium in the soil, thereby can improve the availability of urea.The use of on paddy rice, topdressing, though formed product, too single because of fertilizer and weed killer herbicide, the hypotrophy face, it is narrow to kill the grass spectrum, causes the integrated application effect undesirable, is difficult to apply.In fact the multi-functional special use of 16 weight % weeding type paddy rice that Hunan Province Academy of Agricultural Sciences is developing is topdressed is exactly the ammonium hydrogencarbonate that has wrapped up weed killer herbicide, and fertilizer element is still single.The 1972-1974 of Jilin Agriculture University studies show that, after accounting for the penta sodium pentachlorophenate of fertilizer 7 weight %-15 weight % and urea or ammonium hydrogencarbonate and using with, can suppress the nitrification of soil, improves fertilizer effectiveness, and this is similar with day result of study of the cultivated first-class people of written or printed documents paddy.Go to river in the Jiangsu the regional institute of agricultural sciences developed since 1989 with Application and Development Weed removal medicinal fertilizer---the weeding of rice wheat oil series crops is special-purpose fertile, break through former studies and only limited to the frame that straight fertilizer and certain weed killer herbicide mix, adopt multiple multiple (mixing) to close technology and measure, make product really reach the double effects of infertile field and weeding.Through exploration for many years.The series of products that are developed into gone to river in Jiangsu composite fertilizer of regional institute of agricultural sciences factory, Tongcheng City, Anhui chemical industry Co., Ltd, Yuanjiang City, Hunan farmingization Co., Ltd and the industrialization development of Henan Zhumadian area Feng Wang insecticide factory, product is applied in area, the middle and lower reach of Yangtze River.
