Problems solved by technology

At present, the above-mentioned 1-MCP products that can be used for spraying have certain technical problems: (1) Water can dissolve the 1-MCP inclusion complex α-cyclodextrin, so that the 1-MCP gas is easily volatilized from the liquid or during the spraying process Volatilizes into the environment, causing greater waste and reducing the treatment effect of 1-MCP; (2) The processing technology is relatively complicated, the requirements for production equipment are high, the product performance is unstable, and problems such as precipitation are prone to occur
At present, 1-MCP sprayable products are reprocessed on the basis of solid 1-MCP powder, and there is no completely liquid 1-methylcyclopropene liquid preparation that can be used for spraying.

Abstract

The invention belongs to the field of agriculture technology, particularly discloses a 1-methylcyclopropene liquid preparation which is prepared by adding an organic solvent, emulsifier and an auxiliary agent on the basis of a 1-methylcyclopropene stead solution. The 1-methylcyclopropene liquid preparation acts on plants or part of the plants by methods of sprinkling, dipping and the like, and performs a preservation function or functions of resisting environmental threats, inhibiting the generation of hormones of plant ethylene, abscisic acid and the like, and enhancing resistance and the like. Compared with traditional products, the invention has convenient use and wide application range and maximizes the function of 1-methylcyclopropene (MCP), and meanwhile, the invention has the advantages of novel processing idea, simple technology, low cost, low equipment requirement and stable product performance.

Description

(1) Technical field [0001] The invention belongs to the technical field of agriculture, in particular to a liquid preparation of 1-methylcyclopropene. (2) Background technology [0002] 1-Methylcyclopropene, referred to as 1-MCP, is the best fresh-keeping agent for fruits, vegetables and flowers discovered at the end of the 20th century. It can not only inhibit the production of endogenous ethylene in plants, but also inhibit the effect of exogenous ethylene , so as to play the role of delaying aging and keeping fresh. [0003] 1-Methylcyclopropene is a small cycloalkene that exists as a gas at normal temperature and pressure. Due to the large tension in the molecule, it is extremely unstable and generally only exists for about two hours at normal temperature. At home and abroad, after 1-methylcyclopropene gas is synthesized, it is immediately covered with inclusions or absorbed with absorbents to make stable preparation products. The products mainly exist in two forms: sol...
