Rhus verniciflua is one of the most important special economic species in our country. It can produce lacquer, lacquer, lacquer, high-quality wood and medicine with high economic value. First, the distribution of sumac tree in Hebei, origin of central China, is a hi light, intolerant shading, tall deciduous broad-leaved trees in its growth, development and formation of paint liquid, often require more water and Higher heat. According to the Xi’an Botanical Garden survey, annual rainfall of less than 550 mm in the region, there is generally no natural distribution of tree, at the same time, the annual average temperature over 20 ℃ above, there are few tree growth. The distribution of lacquer trees is conditioned by the hydrothermal conditions at the same time. The level of distribution of the tree in China, generally
