Embodiment 1

[0032] 1. Experimental method:

[0033]This embodiment provides a protective agent for fruit tree shears. In the present embodiment, agent A is 50% carbendazim wettable powder produced by Jiangsu Lanfeng Biochemical Co., Ltd., and the trade name is Dafusheng; agent B is 97% pure carbendazim produced by Beijing Soleibao Technology Co., Ltd. α-naphthalene acetic acid and 28-epi-homobrassinolide produced by Yunnan Yunda Science and Technology Agrochemical Co., Ltd., the active ingredient is 0.004% water preparation, and the mass ratio of the two active ingredients of growth hormone is 5:1, that is, the active ingredient of 1000g is 0.2 g of 97% α-naphthalene acetic acid was added to 0.004% of 28-epigobrassin water agent, and the mixture was uniform; agent C was a polyurethane waterproof coating produced by Shanghai Hanlong Industrial Company. Agent A, agent B and agent C are mixed in a mass ratio of 1:20:200. The preparation method of the cutting edge protective agent is as fol...

Embodiment 2

[0039] 1. Experimental method:

[0040] In order to screen suitable substrates for scissor cut protectors, the following experiments were carried out:

[0041] The polyurethane waterproof coating produced by Shanghai Hanlong Industrial Co., Ltd., emulsified asphalt produced by Hejian Hongyang Anticorrosion Material Co., Ltd., Xinshili interior wall matt latex paint produced by Nippon Paint Co., Ltd., and Qingdao Zhongda Agricultural Technology Co., Ltd. Adhesion performance and water resistance experiments were carried out on the 4 different matrix materials of the "beautiful pile" rod coating agent matrix. The specific method is as follows: apply the above-mentioned four kinds of materials evenly on the glass slide with a brush, and then soak in water for 1 week after drying, and check the adhesion of the four kinds of substrates.

[0042] 2. Experimental results and analysis

[0043] The result is as figure 2 As shown, after soaking for one week, Zhongda "beautiful pile"...

Embodiment 3

[0046] 1. Experimental method:

[0047] In order to evaluate the effect of different active ingredients in the protective agent on the effect of the shear cutting edge protective agent, the following experiments were carried out:

[0048] (1) The experiment set up 8 cutting edge protectants, and the specific formulations of the cutting edge protectants in each group are shown in Table 1 below. Among them, in each group of protective agents, the mass ratio of 50% carbendazim wettable powder to water-based polyurethane material is uniformly 1:200.

[0049] Table 1 Formulas of protective agents in different groups

[0050]

[0051]

[0052] (2) In April, apply the above-mentioned 8 different formulas of the cutting edge protection agent to the cutting edge of the apple branch for testing. Select potted apple trees with the same size and growth in the test garden, select 5 branches with the same thickness (0.5-0.8cm) for each tree, and cut off the branches about 10mm from ...

Abstract

The invention discloses a fruit tree branch and trunk cutting bite protective agent and application thereof.The fruit tree branch and trunk cutting bite protective agent comprises an agent A serving as a bactericide, an agent B for promoting cutting bite healing and an agent C serving as a matrix, and the agent A is a triazole bactericide or a methoxy acrylate bactericide; the agent B is selected from one or two of naphthylacetic acid and 28-epiheight brassinolide; and the agent C is a waterborne polyurethane coating. The application refers to the application of the fruit tree branch saw bite protective agent in promoting saw bite healing and preventing and treating branch diseases. The protective agent for the shear saw bite promotes rapid healing of the shear saw bite, is good in adhesiveness on the shear saw bite, high in windshield wiper resistance, good in prevention and treatment effect on branch and trunk pathogenic bacteria on the fruit tree branch and trunk shear saw bite and excellent in comprehensive performance, and a white protective film layer formed on the fruit tree shear saw bite is good in toughness and ductility, high in rain wash resistance and long in service life. The protective agent can be attached to a saw bite for more than one year, the lasting period of the protective agent is greatly prolonged, and the use frequency and the use cost are reduced.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a protective agent for cutting edges of fruit branches and its application. Background technique [0002] Fruit tree pruning is a necessary management measure to maintain yield and quality in production, and the shearing cut caused by pruning is an important invasion site for fruit tree stem diseases. Branch disease is an important disease that threatens fruit trees, such as apple tree rot, ring disease, anthracnose of various fruit trees, etc., which can cause dead branches and dead trees, and seriously harm the health of fruit trees. Protecting the cutting edge is an effective control measure to prevent and control fruit tree stem diseases, which has been widely used in production. [0003] At present, various measures are used in production, such as applying thin mud, Bordeaux pulp or fungicides and then wrapping with plastic film; or applying asphalt, paint or using co...
