The invention discloses a herbicide medicine fertilizer for farmlands, which consists of weeding ingredients, fertilizer ingredients, a retarder, a safener, dispersing auxiliaries and filling materials. The fertilizer is characterized in that: the weeding ingredients comprise mefenacet and bensulfuron methyl; the fertilizer ingredients comprise nitrogen, phosphor, kalium, zinc and boron elements. The invention also discloses a preparation method of the medicine fertilizer. The medicine fertilizer granular formulation of the invention are applied to rice and one time use of the medicine fertilizer can realize both fertilization and weeding, thus reducing the labor intensity and working times of peasants and solving the problem that herbicide and fertilizer need to be applied for twice or a plurality of times under the conditions of the prior art. The medicine fertilizer of the invention effectively guarantees the scientific release of pesticides and fertilizers, prolongs the effective period of products, ensures the double effects of weeding and fertilization, has important significance for effective, scientific and reasonable use of resources and protection of environment and has positive boost to the investment reduction of users in agriculture and production and income increase in agriculture.
Description
Technical field
The present invention relates to be used for the medicine fertilizer technology in farmland, specifically, relate to a kind of fertilizer granules that contains weedicide and compound manure.
Background technology
Mefenacet (mefenacet) is a kind of selectivity inner sucting conduction type weedicide.Main through bud scale and root absorption, conduct to young shoot and the tender leaf of weeds through xylem and phloem, stop weed growth point cell fission to be extended, finally cause plant death.Strong to the paddy rice selectivity, safe.Be applicable to that the rice field prevents and kill off annual grassy weeds.
Benbbensulfuronmethyl (bensulfuron-methyl) is a selectivity inner sucting conduction type weedicide.Can in water, spread rapidly; For weeds root and blade absorb each one of weeds that transfers to; The biosynthesizing of hindered aminoacid, Methionin, Isoleucine stops the division and the growth of cell, and the weed growth function is obstructed; Tender tissue turns to be yellow too early and suppresses the growth of leaf portion, hinders root growth and necrosis.Getting into the interior metabolism rapidly of paddy rice body is harmless inertia chemicals, to rice safety.Be applicable to that the rice field prevents and kill off annual and perennial broadleaf weeds and nutgrass flatsedge.
The combined action that evidence, mefenacet and benbbensulfuronmethyl are mixed to the rice field annual grassy weeds belongs to additive effect, and the two back herbicidal spectrum that is mixed can be complementary.The two control rice field annual grassy weeds that is mixed is feasible, also is necessary.
Weedicide and fertilizer are wanted twice or repeatedly used respectively to rice crop usually, effort again promptly consuming time.In the traditional agricultural production technology, using fertilizer and weedicide to separate, twice or repeatedly use the way of weedicide and fertilizer, increased peasant's labour intensity and work number of times, unfavorable agricultural development.
In order to reduce to labor capacity; Improve weeding, fertilization effect; At present existing scientific and technical personnel study with the medicine fertilizer of fertilising double effects having weeding; Like publication number is the invention of CN1058760A " rice weeding chemical fertilizer ", and adopting careless peace, simetryn, bentazone compound herbicide and urea or composite fertilizer is that carrier is processed Weeding chemical fertilizer.That all is that all right is ripe in research work, and this respect open source information also seldom but as a whole.
Summary of the invention
The objective of the invention is to: the deficiency to prior art provides a kind of farmland fertilizer with herbicide; But so that in agriculture prodn, not only can apply fertilizer but also weeding through applied once; Overcome the way that user under the prior art condition wanted twice or repeatedly used weedicide and fertilizer, save time and artificial.
Above-mentioned purpose of the present invention realizes through following technical scheme:
A kind of farmland fertilizer with herbicide is provided, and it is made up of herbicidal constituents, fertilizer component, sustained release dosage, safener, dispersing auxiliary and filler.Wherein, said herbicidal constituents comprises mefenacet and benbbensulfuronmethyl; Said fertilizer component comprises nitrogen, phosphorus, potassium, zinc and boron; The weight percent of each component is following:
Herbicidal constituents: mefenacet 0.01～10%, benbbensulfuronmethyl 0.01～5%;
Fertilizer component: nitrogen element 5%～25%, phosphoric 1%～10%, potassium element 1%～15%, zinc element 0.1%～5%, boron 0.1%～5%;
Auxiliary agent: sustained release dosage 0.1%～5%, safener 0.05%～5%, dispersing auxiliary 0.5%～5%;
Surplus is a filler.
Described nitrogen, phosphorus, potassium, zinc and boron can be respectively from urea, monoammonium phosphate, vitriolate of tartar, Zinc Sulphate Monohydrate and boraxs.
Described sustained release dosage preferably polyethylene alcohol or gum arabic.
The preferred fenclorim of described safener.
Preferred W-Gum of described dispersing auxiliary or sweet potato starch.
The preferred kaolin of described filler.
The present invention also provides the preparation method of described farmland fertilizer with herbicide, may further comprise the steps:
Herbicidal constituents, fertilizer component, sustained release dosage, safener, dispersing auxiliary and the filler of said ratio are mixed together granulation, after dry, film-coating technique prepared goes out said paddy field weed-killer fertilizer granules product.
Further among the preparation method of preferred described farmland fertilizer with herbicide; Mixing process adopts the method for fractional steps; To guarantee the homogeneity of product content, be about to the former medicine of mefenacet and benbbensulfuronmethyl and mix with safener, dispersing auxiliary, sustained release dosage earlier, mix with surplus stock again.
In the preferred manufacturing procedure, said drying temperature is controlled the variation of drying temperature and decomposition and the loss that agricultural chemicals, fertilizer composition are avoided in fluctuation at 110～120 ℃ through strictness.
The present invention also provides the application of described farmland fertilizer with herbicide in preventing and controlling weed in rice field.
Compared with prior art, the present invention has following unusual effect:
1. the present invention combines a kind of fertilizer granules of developing through weedicide with the science of fertilizer, has alleviated peasant's labour intensity and work number of times.
2. this product adopts current up-to-date slow release method to guarantee that effectively the science of agricultural chemicals, fertilizer discharges; Prolong the lasting period of product, guarantee weeding, fertilising double effects, add the safety that safener has fully guaranteed crop; Improve drug effect and agricultural chemicals utilization ratio, reduce the waste of agricultural chemicals, fertilizer.Therefore this technology to effective, science, make rational use of resources, the protection environment has great significance, and the agricultural input that reduces the user and the increasing both production and income of agricultural are also played positive pushing effect.
3. the present invention is a kind of efficient paddy rice farmland herbicide; After mefenacet and benbbensulfuronmethyl are mixed; What can enlarge weedicide kills the grass spectrum, strengthens the preventing and kill off of gramineous weeds, particularly the preventing and kill off of annual and perennial weeds to rice terraces such as the barnyard grass grass of rice terrace, lady's-grass, Semen Euphorbiae, Sheathed Monochoria, Herba potamogetonis distincti, Herba Cyperi Glomerati, Herba Cyperi Difformiss; Have active high, good drug efficacy, be difficult for producing characteristics such as resistance.And to rice safety, simultaneously it also is that a kind of fine crop growth is regulated fertilizer, possesses medicine, fertile double effects, the saving of labor, save time, laborsaving, economical.
4. chemical property of the present invention is stable, is convenient to store transportation; Safe in utilization, easy, consumption is few, duration of efficacy is long, have a wide range of applications.
For embodying effect of the present invention better, prove with the fertile field control effectiveness test of paddy field weed-killer medicine of the present invention below.
