Embodiment 1

[0035]

[0036] The above groups are measured separately. First, dissolve polyvinyl alcohol in deionized water at 98°C. Under constant temperature conditions, use a DF-101S collector type constant temperature heating magnetic stirrer to continue stirring at a speed of 10-30r / s for 30 minutes to completely dissolve. After cooling to 45°C; fully mix the simethicone emulsifier and polydimethylsiloxane, and use IKA mechanical stirring at a speed of 500-2000r / s to continue stirring for 20-40min until it is completely emulsified into a paste, emulsified The temperature is 25-100°C; pour thiabendazole, polyethylene glycol-400 and the emulsion into the prepared polyvinyl alcohol solution one by one, stir until fully mixed, and prepare the composite antibacterial film liquid.

[0037] Spray the polyvinyl alcohol composite antibacterial film liquid on the chickpea planted in the greenhouse in the form of spray through hydraulic equipment, and form a film on the chickpea; set the contr...

Abstract

The invention relates to an antibiosis pest-resistant packaging membrane used before fruit harvest, which belongs to the field of agricultural product insecticidal degerming. The antibiosis pest-resistant packaging membrane comprises the following components in parts by mass: 100 parts of a base material, 1000-3000 parts of deionized water, 1-50 parts of an antiseptic, 2-30 parts of a plasticizer, 2-40 parts of an auxiliary agent, and 3-60 parts of an emulsifier. The preparation method comprises the following steps: the components are metered according to the above formula, then dissolved and blended at the temperature of 30-100 DEG C, then the material is cooled, and the product is sprayed through hydraulic equipment to the fruit trees in a spray form for forming the membrane. The membrane has the advantages of good biodegradability, mechanical property, obstruct performance and antibacterial property, and can substitute pesticides and fruit tree sleeve bags in the field of agricultural product insecticidal degerming.

Description

technical field [0001] The invention relates to the field of insecticide and bacteria removal of agricultural products, and more specifically relates to an antibacterial and insect-resistant packaging film used for preharvest fruits and a preparation method thereof. Background technique [0002] my country's protected fruit tree cultivation began in the 1980s. According to incomplete statistics, by the end of the 1990s, the cultivation of protected fruit trees in the country had reached more than 100,000 hectares, which is far ahead in the world. Among them, the cultivation area of ​​strawberries, grapes, peaches and nectarines is the largest. More than 95% of the cultivated area of ​​the entire fruit tree protection area. At present, grapes, peaches, etc. are cultivated in large areas in the east, west and north of Guangdong. However, during the implementation of fruit tree cultivation, the erosion of diseases and insect pests seriously affects the quality and yield of fruit...
