Abstract
The invention discloses Spathiphyllum leaf extract and its preparation method and application. The preparation method of the Spathiphyllum leaf extract includes steps: slurring Spathiphyllum leaves, and filtering slurry to obtain gelatinous extract which is the Spathiphyllum leaf extract. The invention provides acid rain protectant made of the Spathiphyllum leaf extract and water. The acid rain protectant can be used for acid rain protection for plant leaves. The acid rain protectant sprayed to leaf surfaces to form thin films along with evaporation of water, the thin films prevent the acid rain from contacting with the leaf surfaces, and accordingly, damage of the leaf surfaces by the acid rain is reduced greatly. The Spathiphyllum leaf extract with no additional other chemicals is totally from plants and meets the requirement of environment friendliness.
Description
Technical field
The present invention relates to a kind of white palm leaf extract and preparation method thereof and application in preparation acid rain protective agent.
Background technology
Along with development of productivity, massive discharge of pollutant has caused global environmental pollution and ecological disruption problem, and wherein acid rain has become the great problem of environmental pollution of the world today.The acid rain zone of China also enlarges day by day, progressively northwards passes from southwest, south China, and rainwater pH is also more and more lower in the acid rain center.Acid rain has become present world ecotope subject matter.
The plant area coverage is taken up an area of 27% of sphere area, and blade is the place that plant and atmospheric environment are carried out gas exchange, is the door that atmosphere pollution gets into plant corpus at first, and the injury symptom that plant receives pollutant also often shows on the leaf intuitively.Acid rain can produce severe bad influence to growth and development of plant, causes the plant membrane system injury, causes physiological metabolism disorder etc., finally influences yield and quality.
Both at home and abroad about how preventing article and patent that plant receives the acid rain infringement seldom, only several pieces are reported as 1. Zhou Qing etc. and use NaHSO
3-Ca
2+Be that main complex reagent sprays wax plum plant 2 times with 100mg/LAN, can obviously alleviate pH and be 2.0 Simulated Acid Rain to the injury of wax plum plant (week is blue or green. urban environment and urban ecology, 1997.2).2. the reaction that crop antioxidase system coerces acid rain has systematically been studied in the Guizhou Environmental Protection Science Institute; Systematically inquired into its physiological ecological coping mechanism, the protection effect that acid rain is influenced crops with regard to rare earth element carried out studying (Guizhou Environmental Protection Science Institute. the crop antioxidase is to the response of acid rain, HG, CD, PB and rare earth protection [Z] .2004 to acid rain).3. bent Xu Dong etc. makes the safeguard procedures to Foshan acid rain damage on the basis of research Injury Mechanism and resistance mechanism, comprise the plan of introducing a fine variety, cultivation management method and protective agent exploitation (Qu Xudong. scientific and technological information (academic research), 2008.9:611-613).4.IKILUN KK etc. utilize alkali metal or alkaline earth metal, volcanic ash slag to add organic acid, formation water INSOL cellulose mucus film is protected (IKILUN KK.JP5310520-A [P]) to the leaf and the stem that under plant acid rain condition, spread under drying condition.But these reports have utilized alkali metal or alkaline earth metal etc. that environment is had the chemical substance of potentially contaminated more, or raw material is not easy to obtain, and prepare defectives such as difficulty.In sum, study a kind of pollution-freely, raw material is easy to get, and plant acid rain protective agent with low cost has the prospect of using widely.
The white palm is a perennial evergreen draft ornamental foliage plant, 40～60 centimetres of plant heights, and mostly the short rhizome of tool is the shape of growing thickly.Leaf Long Circle or nearly lanceolar, two ends are point gradually, the base portion wedge shape.But plant division and seed propagation are good ornamental foliage plants, southern area can plant, other the area how potted plant viewing and admiring.The white palm is to suppress the waste gas of human body exhalation such as " expert " of ammonia and acetone.Simultaneously its benzene, trichloro-ethylene and formaldehyde in also can filtered air is especially remarkable to absorbing airborne sulphur dioxide effect.
Summary of the invention
The purpose of this invention is to provide a kind of white palm leaf extract and preparation method thereof and application.
The preparation method of a kind of white palm leaf extract provided by the invention comprises the steps: to process slurry with slapping leaf in vain; Filtering said slurry must filtrate and be said white palm leaf extract.
Among the above-mentioned preparation method, filtrating is the liquid of glue; Can said white palm leaf extract envelope behind high-temperature sterilization be preserved.
Among the above-mentioned preparation method, juice extractor capable of using is processed slurry with said white palm leaf, before the slurrying, can with clear water said white palm leaf be rinsed well earlier, then water is dried, with promptly can be made into slurry after the scissors fragmentation.
Among the above-mentioned preparation method, gauze capable of using filters said slurry; The order number of said gauze can be 50 orders～100 orders.
The present invention also provides the white palm leaf extract by method for preparing.
The present invention also provides the application of above-mentioned white palm leaf extract in preparation acid rain protective agent.
The present invention also provides a kind of acid rain protective agent, is made up of above-mentioned white palm leaf extract and water.
In the above-mentioned acid rain protective agent, the volumn concentration of said white palm leaf extract can be 0～90%, but is not 0,
In the above-mentioned acid rain protective agent, the volumn concentration of said white palm leaf extract can be 17%～50%, specifically can be 17%, 20%, 25%, 33% or 50%.
The present invention also further provides the effect of above-mentioned acid rain protective agent in protection acid rain corrodes plant leaf blade.
In the above-mentioned application, said acid rain protective agent specifically can be used for protecting the erosion of acid rain to the Kidney bean blade.
When using said acid rain protective agent, it is sprayed on the plant leaf blade that prevention protects gets final product.
White palm leaf extract provided by the invention is alkalescent, in the ability and acid rain, improves the pH value of acid rain, the grade of reduction acid rain; Should whitely slap the leaf extract gel; Spray behind the blade face evaporation along with moisture; Form thin film, stopped acid rain contact blade face, confirm through pot experiment and field trial; Acid rain protective agent provided by the invention can significantly reduce the damage of acid rain to plant leaf surface, plays the protective effect to plant; Should not add any other chemicals by white palm leaf extract, from plant self, met environment protection requirement fully.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, the present invention is described in further detail below by the specific embodiment.
Method described in the following embodiment like no specified otherwise, is conventional method; Said reagent and material like no specified otherwise, all can obtain from commercial sources.
