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 ...
