preparation example Construction

[0027] The preparation method of the germination inhibitor of embodiment 1~3 is:

[0028] a, preparation of Juglans extract: Juglans leaves and fruit green peel are dried, pulverized, ground, and passed through a 40-mesh sieve; add dehydrated alcohol with 15 times the dry powder quality, and soak for 6 hours; ultrasonically extract the filtrate 2 times, each time 30 Minutes, suction filtration, discard the filter residue, and combine the extracts; the obtained extracts are flashed and concentrated to 10% of the volume of the original extracts at 70°C to obtain the Juglans extract, wherein the content of juglone is 0.02 ~0.05%;

[0029] b. Mixed raw materials: first, import ethyl acetate into the container according to the mass ratio; secondly, in the stirring process, add the extract of Juglans, nonanoic acid, hexazinone and abscisic acid in sequence; finally, add dodecane Sodium sulfate, wetting and dispersing agent SP~SC3266 and methyl silicone oil, stir the above mixture e...

Embodiment 4

[0033] Take 1 part by mass of the germination inhibitor of Example 2, add 20 parts by mass of water, mix well, and inject 20ml of liquid medicine into the root of each felling pile with a syringe.

Embodiment 5

[0035] Get 1 mass part of the germination inhibitor of Example 2, add 50 parts by weight of water, mix uniformly, fully spray the exposed bark on the cross-section of the felling pile and the aboveground part of the stump with a sprayer, and spray the entire cross-section of the felling pile and the aboveground part of the stump Partially exposed bark is fully sprayed.

Abstract

The invention relates to the technical field of plant germination inhibition, in particular to a germination inhibitor, a preparation method and a use method thereof. The germination inhibitor comprises Juglans mandshurica extract solution, nonanoic acid, hexazinone and abscisic acid. The mass ratio of Juglans mandshurica extract solution, nonanoic acid, hexazinone and abscisic acid is (30-50): (3-5): (5-10): (0.5-1). The invention has the advantages of high germination inhibiting efficiency, non-toxic environmental protection, convenient use, saving a lot of cutting and shrub work, saving labor and time, and lower treatment cost, and is a more economical, safer and effective method for treating oak stumps, and can be popularized and applied.

Description

technical field [0001] The invention relates to the technical field of plant germination suppression, in particular to a germination inhibitor, a preparation method and a use method thereof. Background technique [0002] At present, many natural forest regeneration methods are based on budding regeneration, supplemented by seed regeneration. For example, most of the existing oak forests in my country are secondary sprouting forests. Since our country has always carried out coppice forest operations in the history of oak forests, the cuttings after clearcutting have been used to produce sprouts. This has been done for many generations, and the age of some of the felling piles can no longer be estimated. I don’t know how many stubbles have been felled. This kind of oak forest has absolutely no production prospects, which is also the root cause of the low yield, low quality, and low ecological benefits of oak resources in my country. [0003] In the management of natural forest...
