Embodiment 1

[0023] Embodiment 1, the preparation of leaf extract

[0024] Pick off the leaves of the fresh white palm, put them in a beaker, rinse them with clean water three times, dry the water on the leaves, break them with scissors, put them into a juicer and grind them into a uniform slurry, and wrap the gauze (the other) with a rubber band. The mesh number is 50 mesh to 100 mesh) fixed on the beaker, the above slurry is poured on gauze and filtered.

Embodiment 2

[0025] Embodiment 2, the preparation of acid rain protective agent

[0026] The white palm leaf extract prepared in Example 1 is mixed with water to obtain the acid rain protective agent, and the volume percentage content of the white palm leaf extract is prepared respectively to be 50%, 33%, 25%, 20% and 17% acid rain protection agent.

[0027] The pH value of the acid rain protection agent prepared by the present invention has been measured many times, and its average value is shown in Table 1. As can be seen from Table 1, the acid rain protection agent is weakly alkaline.

[0028] Table 1 pH value of acid rain protection agent

[0029]

Embodiment 3

[0030] The indoor test of the acid rain protective agent that embodiment 3, the concentration of the leaf extract of Rhododendron prepared in embodiment 2 is 50%

[0031] Plant kidney beans in pots in the greenhouse. When the kidney beans grow two true leaves, each leaf grows to more than 12cm 2 At 4:00 p.m. every day, the acid rain protective agent with a concentration of 50% was evenly sprayed 5 times on the bean leaves, and then the moderate acid rain with a pH value of 5.15 was sprayed on the bean leaves 5 times, and the control group was sprayed with clear water. (CK).

[0032] After the experiment is completed, the paper weight ratio measurement method is used to measure the corroded area of ​​the blade. The specific experimental method is: take a transparent rice paper A4 size, weigh it, and measure its area. , followed by weighing and measuring its area. Take the ordinate as the weight, and the abscissa as the area, make a standard curve, draw the irregular area of ​...

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 [0001] The invention relates to a white palm leaf extract, a preparation method thereof and an application in preparing an acid rain protective agent. Background technique [0002] With the development of productivity, a large amount of pollutant discharge has led to global environmental pollution and ecological damage, among which acid rain has become a major environmental pollution problem in the world today. The area of ​​acid rain in my country is also expanding day by day, moving from southwest and south China gradually to the north, and the pH of rainwater in the center of acid rain is also getting lower and lower. Acid rain has become the main problem of the world's ecological environment. [0003] Plants cover 27% of the Earth's area, and leaves are the place where plants exchange gas with the atmospheric environment, and are the portal through which air pollutants first enter plants. The symptoms of plant damage from pollutants are often intuitively...
