Description
Technical Field
The invention relates to a rubber tree cut surface cold-proof protective agent with firm bonding and a preparation method thereof, belonging to the field of agricultural medicaments.
Background
The safe winter protection and overwintering of the rubber tree cut surface is one of important measures for improving the yield and preventing diseases of the rubber tree. However, in winter when the rubber trees stop tapping, the rubber is blown off due to the invasion of cold current, so that the growth of the rubber trees and the amount and quantity of the gum produced in the next year are influenced, and in order to ensure that the rubber trees can safely live through the winter, the method of mixing the cattle manure with the yellow mud is used in folk, but the effect is poor. The cut surface is protected from wintering by using vaseline, diesel oil, or mixture of vaseline and rosin, or by coating the mixture of vaseline and diesel oil, palm oil, kerosene, etc. on the cut surface of rubber trees. A "rubber tree cutting surface protective agent" (patent No. 92111143.6) granted by Chinese patent office is prepared by using polyvinyl alcohol, downy blight, zinc sulfate, ammonium molybdate, growth regulator and additive to prepare paste, and coating the paste on the cutting surface in winter, so that the cutting surface can be protected from safe overwintering, the recovery rate of dead skin of the rubber tree is improved by 10-20%, the yield is increased by 7.8%, and the rubber tree can be prevented from strip ulcer. But the cost is relatively high due to more raw materials. And experiments in practice prove that the sealing is required to be carried out more than once every year in winter. The invention discloses a rubber tree cutting surface antifreezing protective agent (patent number: 01106038.7), which is prepared by using wax substances, an emulsifier, a plant growth regulator, a tackifier and water to prepare a medicament to coat and seal a cutting surface, wherein the wax substances are reduced second-line distillate oil, reduced third-line distillate oil, reduced fourth-line distillate oil or a mixture thereof, or No. 52-64 commercial paraffin, the emulsifier is a nonionic surfactant or a composite emulsifier consisting of the nonionic surfactant and an anionic surfactant or a cationic surfactant, the nonionic surfactant is a condensation product of fatty alcohol and ethylene oxide or a condensation product of fatty acid and ethylene oxide, the anionic surfactant is a saturated or unsaturated fatty acid salt, the cationic surfactant is triethanolamine fatty acid salt, the tackifier is natural resin rosin or synthetic resin polyisobutylene, petroleum resin or a mixture thereof, and the plant growth regulator is indolebutyric acid. The protective film formed by the agent has long retention time, can ensure that the rubber tree and the cut surface thereof can safely live through the winter when encountering severe winter with windy and overcast and rainy days, and has good healing of the bark of the cut surface, small dry surface of the bark of the cut opening and small internal shrinkage length of the cut line latex pipe. The disadvantages of the method are that the raw materials are various and complex, and the production cost is high. Another invention relates to a cold-proof coating agent for rubber tree cut surfaces and a production method thereof (patent number: CN 100394850C), which is prepared by adding vaseline into rubber seed oil, and the rubber tree cut surfaces are coated once to protect the cut surfaces from wintering safely. The disadvantages of the method are that the raw material source is narrow, and the production process is complex.
