520			_aMany years of large-scale trials of a newly made protective coating for rubber panel against winter cold reveal that it is more effective than the conventionally used protective coatings such as the vegetable oils (rubber seed oil, palm oil, castor oil), waxes (paraffin wax, beeswax) and rosin mixture coating, the petrolatum coating and the wet clay and cattle dung mixture coating. It can not only protect the rubber panel against cold in winter, but also increase rubber yield in the early period of the next year, promote the growth of the regenerated panel bark and the recovery of the dry panel. Application of the new protective coating is convenient, and has not caused any disease in the panel up to now.
