Embodiment Construction

[0024] Take holly holly, wash it with deionized water for 2 to 3 times, then air-dry it naturally, put it into a pulverizer and grind it, pass through a 40-mesh sieve to get holly holly powder, take 10-15kg of holly holly powder, add it to 30-40kg of ether, and mix it at 40 Stir at 200-300r / min at ~50°C for 20-30min and then filter to obtain the filter residue. Soak the filter residue in 60-80kg of a mixture of petroleum ether and absolute ethanol mixed at a mass ratio of 1:1, at 70-75°C Extract at 200-300r / min for 5-6 hours and then filter to obtain the crude extract and filter cake. Soak the filter cake in 30-40kg of chloroform, extract at 50-55°C for 5-6 hours, and then filter to collect the filtrate and filtrate. , combine the filtrate and the crude extract, put it into a rotary evaporator and evaporate it to dryness, then add the evaporated product to 1.5-2.0kg of n-heptane, seal it and let it stand at 0-4°C for 20-24h. After the storage is completed, filter and collect t...

Abstract

The invention relates to a plant water-saving antitranspirant and a preparation method thereof, and belongs to the technical field of plant water-saving agents. The plant water-saving antitranspirantis capable of using a wax layer of ammopiptanthus mongolicus skin to combine with n-dodecyl alcohol, n-hexadecyl alcohol and aromatic alcohol, and is sprayed on the leaf surface to form a layer of a transparent molecular film, so the mass transfer resistance of water gas-liquid transmission is increased, the antitranspirant achieves the effect of a vapor exchange energy barrier and has the stronginhibition and water retaining effect, the antitranspirant can be rapidly and autonomously spread out to form the molecular film after sprayed on the leaf surface, and a leaf surface water evaporationrate can be effectively delayed. The plant water-saving antitranspirant is capable of using drought-resisting stress-resisting natural substances, such as more than ten types of amino acids and alkaloid contained in the ammopiptanthus mongolicus, to combine with a drought-resisting element, keeping and improving the plant cellular affinity and water retaining capacity, preventing the cell dehydration, enabling plant cells to have the apparent drought-resisting capacity, reducing the plant water transpiration, remarkably increasing the chlorophyll content, improving the photosynthesis, enhancing the plant enzyme system physiological activity, and stimulating the growth of a plant root system.

Description

technical field [0001] The invention relates to a plant water-saving anti-transpiration agent and a preparation method thereof, belonging to the technical field of plant water-saving agents. Background technique [0002] With the impact of global warming and human activities, water resources have gradually become one of the main factors restricting social and economic development. In my country, agriculture is the basic industry of the national economy, but due to the uneven distribution of water resources and backward basic water conservancy facilities, the water utilization rate of agricultural irrigation is only 40%. According to the survey, China's desertified land is 2.62 million square kilometers, which is more than twice the total area of ​​cultivated land in the country, and it continues to show an expanding trend. Serious ecological crisis makes water resources more precious, and water resource crisis and frequent droughts interact with each other, forming constrai...
