一、漆树资源调查及本地良种的选择就地选择漆树优良品种是培育速生丰产漆林的途径之一。近两年来,我所把漆树品种资源调查与本地良种漆树的选择结合起来进行。初步查明我县境内漆树分布有野生和栽培两大类。其中野生漆树产漆量约占全县商品漆的90%以上,人工栽培漆树只占10%。我们通过与漆农座谈,再进行实地调查,感到野生大木漆类型和农家漆树类型在形态特征和生物学特性及经济性状上有较大的差异。在经济性状方面主要表现为人工栽培漆树流漆快、产量高、质量好,树皮脆而易割口。野生大木漆树流漆慢、产量低。这就为就地选优提供了条件。
First, the tree resources survey and the selection of local elite In situ selection of excellent varieties of tree is to cultivate fast-growing high-yielding forest one of the ways. In the past two years, I have conducted a survey on the resources of the tree species and the selection of the local tree species. Preliminary identification of the distribution of lacquer trees in our county have two major categories of wild and cultivated. Among them, the production of wild lacquer tree accounts for more than 90% of the commodity lacquer in the whole county, while artificial cultivated lacquer tree accounts for only 10%. Through discussion with farmers and field investigation, we found that there are great differences in morphological characteristics, biological characteristics and economic traits among wild wood types and farmhouse tree types. Mainly in the economic traits of artificial flowering paint flow faster, high yield, good quality, bark crisp and easy to cut. Wild wood lacquer flow slow paint, low yield. This provides the conditions for the selection on the spot.
