Embodiment 1

[0059] A medicament for inhibiting flower bud differentiation of garden evergreen tree species, after fully dissolving 350g of the original drug 2,6-dinitro-N,N-dipropyl-4-trifluoromethylaniline in 500g of xylene solvent, Add 30 grams of NP-10 and 30 grams of Span-80 emulsifiers, stir well to make an emulsifiable concentrate, then add 40 grams of glycerol as antifreeze, 2 grams of polydimethylsiloxane as a defoamer, and 25 grams of naphthalene The sulfonate-formaldehyde condensate is used as a dispersant, 1g of ethyl p-hydroxybenzoate sodium salt is used as a stabilizer, and when it is less than 1000g, it is supplemented with the solvent xylene, and finally fully stirred to make an emulsifiable concentrate to obtain the target agent.

[0060] The medicament for inhibiting the flower bud differentiation of garden evergreen tree species in Examples 2 to 5 is carried out according to the method in Example 1, the difference is that the medicament for inhibiting the flower bud diffe...

Embodiment 6

[0064] A medicament for inhibiting flower bud differentiation of garden evergreen tree species is carried out according to the method of Example 1, the difference is that the former drug selects N-sec-butyl-4-tert-butyl-2,6-dinitroaniline and 6-dinitroaniline -Dinitro-N,N-dipropyl-4-trifluoromethylaniline mixed in a 1:1 ratio.

Embodiment 7

[0066] A medicament for inhibiting flower bud differentiation of garden evergreen tree species, carried out according to the method of Example 1, the difference is that the original drug is selected from 1,2-dihydro-3,6-pyridazinedione and 6-dinitro -N,N-Dipropyl-4-trifluoromethylaniline was mixed in a ratio of 4:5.

Abstract

The invention discloses an agent for inhibiting flower bud differentiation of garden evergreen tree species. Based on 1000 weight parts of raw materials, the agent is prepared from the following raw materials: 5-660 parts of a technical material and the balance of an aid, wherein the technical material is selected from any one or both of dinitroaniline herbicides and 1,2-dihydro-3,6-pyridazinedione at any ratio. The invention also provides a use method of the agent for inhibiting flower bud differentiation of garden evergreen tree species, and the method comprises the step of spraying the agent with the technical material concentration of 3-60 g / L or injecting the agent at a ratio of the original agent dose to the diameter at breast height of 3-60 g / dm to trunks 1 to 50 days before the physiological differentiation period of flower buds of garden evergreen tree species. The agent has the advantages that the flower bud differentiation of the garden evergreen tree species can be inhibited, and the flower buds can be differentiated into leaf buds, thereby effectively solving the problems that the vigor of the garden evergreen tree species is weak due to a large amount of fruits of thegarden evergreen tree species, the falling of mature fruits onto roads causes environmental pollution, fruits become wintering places for pests in the garden evergreen tree species and the like.

Description

technical field [0001] The invention relates to the field of landscaping, more specifically, it relates to a medicament for inhibiting flower bud differentiation of garden evergreen tree species and its application method. Background technique [0002] After the garden plants are about to enter the prime stage or mature stage, the growth of their canopy and green volume will be small or no longer. And mature garden plants will also enter the peak fruiting period. However, a large number of flowering and fruiting of garden plants will consume a lot of tree nutrients. It is necessary to mobilize stored inorganic and organic nutritional components from roots and branches to provide carbon skeletons, energy and protoplasmic components for its growth and development, so that garden plants are overloaded. Severe, showing that the leaves of broad-leaved garden plants start to burn and turn yellow before the fruit matures, and the coniferous garden plants start to wither and turn y...
