Novel fumigation preparation and application technology thereof

Abstract

The invention discloses a novel fumigation preparation and application thereof to the quarantine treatment of agricultural products such as fruits, vegetables, flowers and the like. The invention is characterized in that the fumigation preparation is a mixed gas of bromomethane with the purity of 99.95 percent and phosphorus hydride with the purity of 99.995 percent in different proportions, or a mixed gas of bromomethane with the purity of 99.95 percent, phosphorus hydride with the purity of 99.995 percent and air in different proportions, or a mixed gas of bromomethane with the purity of 99.95 percent, phosphorus hydride with the purity of 99.995 percent and carbon dioxide with the purity of 99.95 percent, or a mixed gas consisting of controlled atmosphere gas used for fresh-keeping storage of fresh agricultural products; and the fumigation condition is that the fumigating time is between 1.5 hours and 16 days and the fumigation is the normal temperature fumigation or low temperature fumigation of between 0 and 30 DEG C. The novel fumigation preparation has better synergistic effect among the components, effectively reduces the usage amount of the bromomethane of the conventional fumigation preparation and avoids the damage of the fumigation to the fresh agricultural products such as fruits, vegetables, flowers and the like.

Description

technical field [0001] The invention relates to the treatment of harmful organisms in the quarantine of fresh and live agricultural products, in particular to a new type of fumigating formulation for fruits, vegetables and flowers and its application technology. Background technique [0002] The wanton spread of harmful organisms on fresh agricultural products such as fruits, vegetables, and flowers in our country causes huge economic losses every year, seriously threatens the ecological environment and agricultural and forestry production safety of our country, and has a serious impact on the export of high-quality agricultural products in our country. Therefore, in the import and export trade of fresh and live agricultural products, quarantine treatment is generally required to kill harmful organisms and prevent their spread. [0003] Among them, fumigation treatment is one of the most widely used quarantine treatment technologies, which has the advantages of economy, prac...

AI Technical Summary

Problems solved by technology

[0005] As fresh agricultural products, fruits, vegetables and flowers are mostly fumigated at room temperature. Some agricultural products have high quality requirements and are mostly stored and transported at low temperature. Fumigation at low temperature, currently there is no effective mixed fumigation formulation that can be used for fresh and live agricultural products, which can effectively kill harmful organisms that may be carried by the goods, but also damage the quality of agricultural products
