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 preparing the acid rain protective agent.
Background technology
Along with the 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 is expanding day also, from southwest, south China, progressively northwards passes, and rainwater pH is also more and more lower in the acid rain center.Acid rain has become current World Ecosystem environment subject matter.
The vegetal cover area takes up an area 27% of sphere area, and blade is the place that plant and atmospheric environment are carried out the gas exchange, is the door that atmosphere pollution enters plant corpus at first, and the injury symptom that plant is subject to pollutant also often shows on leaf intuitively.Acid rain can produce serious adverse effect to growing of plant, causes the plant membrane system injury, causes physiological metabolism disorder etc., finally affects yield and quality.
Both at home and abroad about how preventing that plant is subject to the article of acid rain infringement and patent seldom, only several pieces are reported as the NaHSO such as 1. Zhou Qing
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 of crop Antioxidant Enzyme Systems to acid rain stress systematically studied in Guizhou Environmental Protection Science Institute; systematically inquired into its physiological ecological coping mechanism, with regard to rare earth element to the protection effects of Acid Rain Effect crops be studied (Guizhou Environmental Protection Science Institute. the crop antioxidase is protection [Z] .2004 to acid rain to the response of acid rain, HG, CD, PB and rare earth).3. bent Xu Dong etc. is on the basis of research Injury Mechanism and resistance mechanism, make the safeguard procedures for Foshan acid rain damage, 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; form water INSOL cellulose mucus film under drying condition, the leaf and the stem that spread under plant acid rain condition are protected to (IKILUN KK.JP5310520-A[P]).But these reports have utilized alkali metal or alkaline earth metal etc. environment to be had to the chemical substance of potentially contaminated more, or raw material is not easy to obtain, the defects such as preparation 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 prospect of the application widely.
The white palm is perennial evergreen draft ornamental foliage plant, 40～60 centimetres of plant heights, and the short rhizome of tool, mostly be 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, be good ornamental foliage plant, can plant on ground other how potted plant viewing and admiring in area at southern area.The white palm is to suppress " expert " of the waste gas of characteristics of contaminated respiratory droplets as ammonia and acetone.Simultaneously its benzene, trichloro-ethylene and formaldehyde in also can filtered air, 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, comprise the steps: to make slurry by slapping in vain leaf; Filtering described slurry obtains filtrate and is described white palm leaf extract.
In above-mentioned preparation method, filtrate is gluey liquid; Described white palm leaf extract envelope after high-temperature sterilization can be preserved.
In above-mentioned preparation method, can utilize juice extractor that described white palm leaf is made to slurry, before slurrying, can first with clear water, described white palm leaf be rinsed well, then water be dried, with can be made into slurry after the scissors fragmentation.
In above-mentioned preparation method, can utilize gauze to be filtered described slurry; The order number of described gauze can be 50 orders～100 orders.
The present invention also provides the white palm leaf extract prepared by said method.
The present invention also provides the application of above-mentioned white palm leaf extract in preparing the acid rain protective agent.
The present invention also provides a kind of acid rain protective agent, above-mentioned white palm leaf extract and water, consists of.
In above-mentioned acid rain protective agent, the volumn concentration of described white palm leaf extract can be 0～90%, but is not 0,
In above-mentioned acid rain protective agent, the volumn concentration of described 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 above-mentioned application, described acid rain protective agent specifically can be used for protecting the erosion of acid rain to Phaseolus Leaves.
While using described acid rain protective agent, it is sprayed on the plant leaf blade of pre-protection and gets final product.
White palm leaf extract provided by the invention is alkalescent, in energy 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 blade face the evaporation along with moisture, form thin film, stopped acid rain contact blade face, through pot experiment and field trial, confirm, 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 better technical scheme of the present invention, below by embodiment, the present invention is described in further detail.
Method described in following embodiment, if no special instructions, be conventional method; Described reagent and material, if no special instructions, all can obtain from commercial channels.
