A kind of composition that is used for the treatment of the bamboo grows dead skin disease
Technical field
The present invention relates to agriculture field, specifically, the present invention relates to a kind of composition that is used for the treatment of the bamboo grows dead skin disease.
Background technology
The same iron and steel of natural rubber, oil, coal are basic industry and the strategic materials that involve the interests of the state and the people together and be called the four big raw materials of industry.As one of the world's four big raw materials of industry, natural rubber is extensively applied to aspects such as industry, agricultural, national defence, communications and transportation, machine-building, medical and health and daily life because of having very strong elasticity, good insulation performance, plasticity, wearability, anti-drawing property, water proof gas barrier properties etc., becomes one of indispensable material in national defence and the industry.Lactiferous plant in the world has kind more than 2000, but at present by establishing in large scale and become natural rubber unique commercial source, is Para rubber tree.But the harm that bamboo grows " dead skin disease " already causes for rubber planting is extremely serious, is one of main limiting factor of natural rubber per unit area yield raising.According to latest survey, no matter reclamation area, Hainan, or reclamation area, Yunnan, bamboo grows dead skin rate average out to about 25%.Even more serious is, the dead skin tree is also with 1% speed cumulative year after year in recent years.
Bamboo grows " dead skin disease " is divided into two types of (Jacob JL, Prevot JC, LacrotteR.1994.Tapping panel dryness in Hevea brasiliensis.Plantations, Recherche, Development, 1 (3): 15-24.): gangrenosum acne " dead skin disease " and non-gangrenosum acne " dead skin disease ".Gangrenosum acne " dead skin disease " is called " trunk phloem necorsis " (Trunk Phloem Necrosis again, TPN), it is characterized in that latex dust and surrounding tissue aging thereof, brownization of endothelium, but this symptom rapid spread extends to the non-face on opposite to whole face when serious.Just gangrenosum acne " dead skin disease " will occur in the rubber tapping treelet soon, even in the treelet of not rubber tapping, generation arranged also.This dead skin is irreversible, because the bark of regeneration is ill too.Someone thinks that gangrenosum acne " dead skin disease " is poisoned by pathogen or cyanogen and caused (Fan Siwei, the cause of disease of the few fine jade .1994. bamboo grows dead skin of poplar and the hypothesis of relevant dead skin, tropical crop research, (4): 43-48).The type " dead skin disease " takes place seldom, does not constitute a threat to producing.Non-gangrenosum acne " dead skin disease " is called " face is dry sick " (Tapeing Panel Dryness again, TPD), now be acknowledged as a kind of cause by injury (rubber tapping) and ethene stimulation (well stimulation of generally adopting on existing the production), complex physical syndrome.The feature of non-gangrenosum acne TPD is that histology, the cytology variation of bark is less, but the latex dust metabolic disorder is serious, during sick sending out, and the local or all latex dusts obstructions of bamboo grows secant, the binder removal amount significantly reduces not even binder removal.This TPD is reversible, as long as allow bamboo grows rest and reorganize about 1 year, but just rehabilitation of bamboo grows.But the generation of this dead skin is very general, and production is constituted a serious threat, and the bamboo grows dead skin of being carried in the industry just is meant this dead skin.Just hold a dead skin symposium every the international rubber research and development committee of 2-3 (IRRDB), that focus on just is non-gangrenosum acne TPD.
Chinese patent ZL 93107276.X discloses a kind of manufacture method for the treatment of vegetable rubber tree dead skin revivifier, and multiple Chinese herbal medicine is handled, dried, grinding and part liquor, mixes stirring, propagandizes the quantitative package of sieving after (burying) hotly.Brown type, outer brown type, stable type, Phytophthora spp, mycosis, lines parasitosis, virus disease (containing diseases such as class gram Ci Shi body) in the medicinal powder treatment intractable bamboo grows dead skin, 1-15 is prolonged to stop cutting the diseases such as bamboo grows dead skin of not producing glue special curative effect, coat medicinal powder of the present invention once, just can open after 3-12 month to cut and bring back to life bamboo grows production glue.
Application number is that 97121908.7 Chinese patent application discloses a kind of preventing and treating chemical for brown spot of rubber tree, and it mainly is made up of tetracyclines (chloramphenicol), methylcellulose, xanthans etc.Suitable being coated with on the disease tree face that imposes on brown spot of rubber tree can be prevented and treated brown spot of rubber tree effectively, and can be made rubber trunk glue output volume increase 14.27%, and cost and benefit ratio are 1: 4.53-6.23.
But people never stopped for the research of new treatment bamboo grows dead skin disease.
Summary of the invention
The purpose of this invention is to provide a kind of composition that is used for the treatment of the bamboo grows dead skin disease.
The present invention also aims to provide the application of hydrogen peroxide in the agricultural chemicals of preparation treatment bamboo grows dead skin disease.
In order to realize purpose of the present invention, the invention provides a kind of composition that is used for the treatment of the bamboo grows dead skin disease, comprise hydrogen peroxide 90-95 weight % and citric acid 5-10 weight %, preferably, comprise hydrogen peroxide 95 weight % and citric acid 5 weight %.
In the present invention, preferably, composition of the present invention also is included as the calcium dodecyl benzene sulfonate of the 0.01-0.05 weight % of described composition, preferably is included as the calcium dodecyl benzene sulfonate of 0.03 weight % of described composition.
Calcium dodecyl benzene sulfonate has another name called agricultural newborn 500#, and it is used for composition of the present invention can further strengthen the effect of eliminating dead skin.
Composition of the present invention can be made various forms, for example can make the form of the aqueous solution.
The origin cause of formation of bamboo grows dead skin disease is very complicated.The cause of disease and pathogenesis around the bamboo grows dead skin disease, people once explored and studied from aspects such as pathology, physiology, heredity, envirment factor, soil and biochemistries respectively, some hypothesis have been drawn, as bark available moisture fluctuation and latex extremely dilute cause a disease says, pathogenic microorganism is pathogenicly said, the locality severe trauma reacts and says etc., but, be much to seek its most essential reason at present about the cause of disease of rubber dead skin disease.So far the method for still not having effectively treatment and control bamboo grows dead skin disease.
Basis of the present invention is that the inventor chances on when hydrogen peroxide is used for bamboo grows, has obtained the prevention dead skin that makes us unexpected, the effect of eliminating dead skin.Based on this, the present invention also provides the application of hydrogen peroxide in the agricultural chemicals of preparation control bamboo grows dead skin disease.In actual use, the aqueous hydrogen peroxide solution of high concentration (for example 80 weight %) although can also can obtain, is generally used for specific purposes, and is for example military.More preferably, the invention provides the application of the following aqueous hydrogen peroxide solution of 40 weight % (being that concentration is greater than 0 and smaller or equal to 40 weight %) in the agricultural chemicals of preparation control bamboo grows dead skin disease.
