Abstract
The invention provides a herbicide-containing fertilizer and a preparation method and use thereof. The herbicide-containing fertilizer, based on 100 percent of total mass, consists of the following formula components in percentage by weight: 15 to 40 percent of glyphosate, 0.4 to 8 percent of trace element compound, 5 to 15 percent of surfactant, 0.5 to 20 percent of stabilizer and the balance of filler. In the herbicide-containing fertilizer provided by the embodiment of the invention, because the glyphosate, trace element component and the like are mixed reasonably, the soil fertility, resistance in crops (particularly glyphosate resistant transgenic corps) and crop yield are all increased, and the crop yield is improved by up to 30 percent; and the herbicide effectively lowers the labor intensity and manual cost of agricultural production. In addition, the herbicide-containing fertilizer is produced by mixing by group or mixing by crushing, so the dispersion uniformity of the components is improved effectively, the preparation method is simple in process and low in energy consumption and the production cost is lowered; and the method is suitable for industrial production.
Description
Technical field
The invention belongs to the pesticide preparation field, relate in particular to a kind of Weed removal medicinal fertilizer and preparation method thereof and application.
Background technology
About the research situation of medicine fertilizer the earliest be the research of Weed removal medicinal fertilizer, the data record sees 1964 " northeastern Japan agricultural field experiment research report " the earliest.In early 1960s, the researchist's research take this paddy cultivated one as representative is sneaked into weedicide pentachlorophenol (PCP) in fertilizer and is used as base manure, to reaching saving power, the purpose of continuity weeding effectiveness.Result of study shows, after using the ammonium fertilizer of sneaking into PCP in the field, can prevent the loss of nitric nitrogen, because PCP can suppress the metabolism of the nitrobacteria in soil, nitrification is hindered, thereby obtain PCP and application of mixed fertilizers and not only can keep its drug effect, and the inhibition nitrification is arranged.The national scientific research personnel such as the U.S., USSR (Union of Soviet Socialist Republics) has also carried out applied research widely to medicine fertilizer, has all obtained certain achievement, for the fertile development of later on more medicine is laid a good foundation.China starts from the eighties in 20th century to the research of medicine fertilizer, is reported as the master with the research and development of Weed removal medicinal fertilizer.
Glyphosate (glyphosate) formal name used at school N-((phosphonomethyl)) glycine; N-((phosphonomethyl)) Padil (Phosphonomethyl Imino Acetic Acid) is a kind of organophosphorus herbicide by the About Monsanto Chemicals exploitation.Glyphosate absorbs by plant leaf and non-woody cauline leaf as non-selective, noresidue herbicide after seedling, conducts to the plant materials each several part.Very effective to dark root perennial weeds and annual and biennial Gramineae, Cyperaceae and broadleaf weeds.The most outstanding characteristics of glyphosate are in can being conducted to underground rhizome downwards and be tillered by the cauline leaf absorption, and are extremely strong to weeds underground organization destructive force.Its herbicide principle is mainly by suppressing the activity of enol acetonyl shikimin phosphate synthase, destroy shikimin to the conversion of phenylalanine, tyrosine, tryptophane, thereby protein synthesis is interfered and causes plant dead.Resistance glyphosate (GT) farm crop are since the U.S. in 1996 releases, and in bamboo telegraph all over the world, cultivated area accounts for 85% of global transgenic crop cultivated area now.Simultaneously, glyphosate (the trade(brand)name agriculture reaches) is used as to be promoted the use of the weedicide of healthy and environmental safety, becomes the most widely used weedicide in the world.
But, find aborning, glyphosate can and make the EPEPS inactivation with enol pyruvic acid shikimic acid-3-phosphate synthase (EPEPS) combination, enol pyruvic acid shikimic acid-3-phosphate synthase is the key enzyme in the plants shikimic acid route of synthesis, it is the necessary enzyme of synthetic aromatic amino acid, die aromatischen Aminosaeuren comprises the indispensable amino acid phenylalanine, tryptophane and tyrosine etc.Meanwhile, this glyphosate is also to the downstream product plant growth promoter---indolylacetic acid and plant defense compound---, and phytoalexin synthesis produces restraining effect, and the crop disease-resistant anti-adversity ability is descended; Resistance glyphosate (GTA) proterties depends on the EPEPS that GT has introduced soil Agrobacterium, it is insensitive to glyphosate, therefore glyphosate is absorbed and is transported to the growth part of root and stem by glyphosate resistant crops, even ooze out from rhizosphere (soil around root system), make crop Mn occur lacking, lack the nutritional deficiency symptoms such as Zn, and have influence on the microflora in soil and be planted in crop growth in this soil.Point out from the pensioner Don lluber of Purdue Univ-West Lafayette USA and G.S.Johal recently, glyphosate is widely used and can " greatly increase the severity of various plant diseases; the system of infringement plant defense pathogenic agent and disease, and fixing soil and plant nutrient makes them can't be by plant utilization " in the U.S..Huber studies discovery, and glyphosate can weaken plant resistance to environment stress, makes it easily be subject to the infection of soilborne fungal pathogens.
Do not add trace element about glyphosate formulation up to now and overcome glyphosate to crop negative impact and genetically modified crops raising resistance and the research report that promotes volume increase.
