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 a medicament for inhibiting flower bud differentiation of garden evergreen tree species. The raw materials for making the medicament are counted in 1000 parts by weight, and the raw materials include: 5 parts to 660 parts of the original drug, and the remaining materials are auxiliary agents; wherein, the The original drug is selected from any one of dinitroaniline herbicides and 1,2-dihydro-3,6-pyridazinedione or a mixture of the two in any proportion. The present invention also provides a method for using a medicament for inhibiting flower bud differentiation of garden evergreen tree species, spraying the above-mentioned medicament at a concentration of 3 g / L to 60 g / L 1 to 50 days before the flower bud physiological differentiation period of garden evergreen tree species Apply or inject the trunk according to the original drug dose of 3g / dm~60g / dm DBH. The invention has the advantage that it can inhibit the differentiation of flower buds of garden evergreen tree species, and then make them differentiate into leaf buds, effectively solving the environmental problems caused by garden evergreen tree species tree vigor weakening and fruit falling after ripening caused by a large number of garden evergreen tree species. Pollution and fruit become overwintering places for garden evergreen tree pests.

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...
