Description

A kind of rubber tree dead skin preventive coating agent and preparation method thereof

technical field

The invention relates to a cut surface application agent for bark, in particular to a rubber tree dead skin control application agent and a preparation method thereof.

Background technique

At present, the dead bark of rubber trees in the world and the stopped cutting plants account for 12-15% of the rubber trees that have been tapped. Many rubber plantations have a dead skin rate of 5-20% within 5 years of cutting. From 2008 to 2009, the Rubber Research Institute of the Chinese Academy of Tropical Agricultural Sciences conducted a survey on the dead bark of rubber trees in 24 state-owned farms (branches) and 8 private farms in the three major rubber planting areas in the country, a total of 32 production units. The survey results show that the average dead skin rate of rubber trees in the three major rubber planting areas is as high as 24.71%, and the dead skin cutting rate is 14.55%. The dead skin cutting rate of a few rubber plantations is even close to 60%. Rubber tree dead bark has become the most serious disaster affecting the output of rubber trees.

The causes of rubber tree dead skin are very complicated, and its research involves multiple disciplines such as pathology, histological anatomy, physiology, biochemistry, genetics and molecular biology, and various hypotheses are put forward from different disciplines. Such as "the theory of pathology caused by pathogenic microorganisms", "the theory of localized severe trauma reaction", "the theory of effective water fluctuations in bark and the extreme dilution of latex to cause disease", "the theory of exhaustion of metabolic reserve substances or nutrient deficiency", "the theory of protein Synthetic disorders lead to the theory of milk duct aging and pathogenesis", "the theory of the decrease of the permeability of the milk duct wall", "the theory of genetic and environmental influence", "the free radical hypothesis", "the theory of defense mechanism and protective response", "the theory of aging" And "the theory of bark tissue necrosis" and so on, but the cause of the dead skin of rubber trees is not yet clear.

With the in-depth study of rubber tree dead skin, rubber planting countries are also strengthening research on dead skin prevention. In the 1980s, some people in our country used the method of opening isolation ditch and peeling from abroad; shallow cutting and rest cutting to promote the recovery of dead skin, and shallow planing lesions plus application of compound trace elements to treat dead skin and stop cutting trees; gibberellin and Fresh cow dung coating treatment.

Based on the pathological hypothesis of rubber tree dead skin, domestic scholars have developed several dead skin control agents. ZL93107276.X discloses a manufacturing method of a dead skin rejuvenation agent for treating plant rubber tree. Various Chinese herbal medicines are processed, dried in the sun, ground and partly boiled, mixed and stirred, fried (buried), and then sieved and packaged quantitatively. The medicinal powder is used to treat obstinate rubber tree dead bark of inner brown type, outer brown type, stable type, strip canker, fungal disease, nematode disease, viral disease (including Kreutzia-like diseases), and it will not stop cutting after 1-15 years. Glue-producing rubber tree dead skin embolisms have a special curative effect, and the powder of the present invention can be applied once, and after 3-12 months, the rubber tree can be cut and revived to produce glue." A kind of rubber tree brown skin disease prevention and treatment agent is disclosed in the application number 97121908.7 , it is mainly composed of tetracycline family drugs, methyl cellulose, xanthan gum, etc. It is suitable for applying to the cut surface of the diseased tree of rubber tree brown bark, can effectively prevent and cure rubber tree brown bark, and can make rubber tree dry gum Yield increased by 14.27%. The above two agents are based on the dead skin caused by pathogenic bacteria. This type of "dead skin" rarely occurs and does not pose a threat to production, so it has not been promoted so far.

Application No. 200810183285.1 discloses a compound preparation for preventing and treating rubber tree dead skin disease and a preparation method thereof. The composite preparation consists of antioxidant substances and methyl cellulose. The antioxidant substance is one or more of reduced glutathione, ascorbic acid, vitamin E or β-carotene, preferably one or both of reduced glutathione or ascorbic acid. This compound preparation can prevent dead skin and eliminate the occurrence of dead skin, and the effect is remarkable. Application No. 201010232889.8 discloses a combination for treating rubber tree dead skin disease. The combination contains 90-95% by weight of hydrogen peroxide and 5-10% by weight of citric acid, and a small amount of calcium dodecylsulfonate. Application No. 201210528962.5 discloses a preparation for preventing and treating rubber tree dead skin disease and its preparation method and application. The purpose of this preparation is to deploy the nutrition of the rubber tree, so that the rubber tree can strengthen the antibody after absorbing the nutrients, so as to gradually restore the dead skin. In addition, some domestic researchers have also developed a series of rubber production-increasing factors or nutrients in order to increase the production of dry colloids and delay the occurrence of dead skin. For example He Xiangdong et al. (Application No. 02123812.X) invented the Hevea rubber production accelerator composed of triethylamine, oxyphenylsulfamide, and carboxymethyl cellulose; Disclosed is a preparation composed of bactericidal agents used for rubber protection and sterilizing, nutritional rubber augmentation and a preparation method thereof.
