Embodiment 1

[0046] The original drug and auxiliary agent are compounded into 20% wettable powder, wherein the original drug includes forchlorfenuron, paclobutrazol, 5-(4,6-dimethyloxypyrimidine-2 -base) carbamoyl sulfamoyl-1-methylpyrazole-4-ethyl carboxylate, auxiliary agent selects NP10, white carbon black, kaolin, and the percentage by weight of each component is as follows: former medicine 20%, NP10 10 %, white carbon black 15%, and kaolin to make up to 100%. The preparation process is to mix each component evenly in a double-screw mixer according to weight percentage, and then pulverize it through an ultrafine pulverizer or jet pulverizer to control the particle size to be less than 325 mesh (wet sieving method), and then mix evenly in another double-screw mixer to obtain 20% wettable powder.

Embodiment 2

[0048] The original drug and auxiliary agents are compounded into 20% wettable powder, wherein the original drug includes indole ester, chlorphenamine, 2',6'-difluoro-5-methoxy in a weight ratio of 1:1:3 Base-8-fluoro[1,2,4]triazol[1,5-c]pyrimidine-2-sulfonanilide, the auxiliary agent is NP10, white carbon black, kaolin, and the weight percentage of each component is as follows: 20% medicine, NP10 10%, white carbon black 15%, kaolin to make up to 100%, the preparation process is to mix each component evenly in a double-screw mixer according to weight percentage, and then pulverize through an ultrafine pulverizer or jet pulverizer , control the particle size to be less than 325 mesh (wet sieving method), and then mix evenly in another double-screw mixer to obtain 20% wettable powder.

Embodiment 3

[0050] The original drug and the auxiliary agent are compounded into 20% wettable powder, wherein the original drug includes 6-benzylaminopurine, GA3, triiodobenzoic acid, 2-[4, 5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5-ethyl-3-pyridinecarboxylic acid, the auxiliary agent is NP10 , white carbon black, kaolin, the percentage by weight of each component is as follows: 20% of the original drug, 10% of NP10, 15% of white carbon black, and kaolin is added to 100%. After mixing evenly in the mixer, pulverize through a superfine pulverizer or jet mill, control the particle size to be less than 325 mesh (wet sieve method), and then mix evenly in another double-screw mixer to get 20% available Wet powder.

Abstract

The invention discloses a thinning chemical for plant pollen, belonging to the technical field of plant growth regulation. The main points of a technical scheme of the invention are as follows: the thinning agent comprises an original chemical and an auxiliary agent, wherein the original chemical is one or more selected from the group consisting of forchior fennron, ethychlozate, 6-benzyladenine,a gibberellin compound, paclobutrazol, uniconazole, naphthaleneacetic acid, indolebutyric acid, 2,4-dichlorophenoxyacetic acid, triiodobenzoic acid, 2-chloroethyl trimetyl ammonium chloride, cycloheximide, chlorpropham, a sulfonylurea herbicide, an imidazolinone herbicide and a triazolopyrimidine herbicide. The invention also discloses an application method for the above-mentioned chemical. According to the invention, in a plant staminate strobilus swelling period, the chemical is diluted to 0.04 to 8 g of the original chemical per L of the chemical for foliar application, or the chemical is injected into the trunk of a plant according to a dosage of 0.1 to 5 g of the original chemical per cm of diameter at breast height, so tree species like platycladus orientalis, sabina chinensis, ginkgo biloba and pinus tabuliformis can be effectively inhibited from generating pollen, and the effect of thinning is excellent.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation, in particular to a plant pollen removing agent and a plant pollen removing method. Background technique [0002] Hay fever has become a global disease that seriously affects human health, such as the incidence of hay fever in European and American countries is 2%-10% (Claudia TH, Anna K, Annette M, et a1.2003. Impact of pollen on human health: more than allergen carriers.Int Arch Allergy Immunol,131:1-13.), the incidence of hay fever among adult residents in Beijing is 2.51% (Wang Tao, Li Sujun, Zhao Liang, et al. 2008. Telephone survey on hay fever among residents over 15 years old in Beijing .Environmental and Health Journal, 25(5):403-404.); Among the allergic rhinitis patients with more than 500 million people in the world, more than 50% are caused by pollen allergy (Bousquet J, Khaltaev N, Cruz AA, et al . 2008. Allergicrhinitis and its impact on asthma (ARIA) 2008 update (i...
