油桐是我县的主要经济林木,长期以来,我县群众就把油桐生产作为整个农业生产的重要组成部份。在自然选择特别是人工选育的双重作用下,形成了适应于一定自然条件及栽培条件的品种类型,其生物学特性及生态学特性的差异,导致了油桐品种类型在经济性状上的有所不同。为查清我县油桐品种资源及其分布,从而广泛地利用优良品种,我们对全县油桐品种资源进行了初步调查,现将调查结果报告于下。
Tung Tung is my county’s main economic forest, for a long time, my county put the production of tung tree as an important part of the entire agricultural production. Under the dual role of natural selection and especially artificial selection and breeding, the types of cultivars adapted to certain natural conditions and cultivation conditions were formed. The differences in their biological characteristics and ecological characteristics led to the differences in the economic traits Different. In order to find out the resources and their distribution of Tung oil varieties in our county, and to make extensive use of fine varieties, we conducted a preliminary investigation on the resources of Tung oil varieties in our county, and the results are reported below.
