本文根据十多年的试验研究结果,较全面地论述了建立和经营油松种子园的各项技术。其主要技术关键有:用2株或3株优势木对比的选优方法,可选择出质量较好的优树;园址选择注意园内母树能正常生长和大量结实;油松夏季嫩枝嫁接是建园的有效嫁接方法,成活率可稳定于90％以上;园内有初果期花粉密度低和无性系之间花期不一致现象,降低了种子产量和质量,辅助授粉可使种子产量提高14.4％以上;优树子代和无性系测定,评出了4个优良家系和23个优良无性系。
Based on the results of more than ten years of experimental research, this paper comprehensively discusses the various techniques for establishing and operating the pine seed orchard. The main technical key are: with 2 or 3 dominance wood comparison of the optimal method, you can choose a better quality of the tree; site selection Note that the parent tree can grow normally and a large number of solid; pine summer grafting Is an effective grafting method for the construction of a garden, the survival rate can be stabilized at more than 90%; the early stage of the garden pollen density is low and flowering inconsistencies between clones, reducing seed yield and quality, assisted pollination can increase seed yield by 14.4 % Above; excellent tree progeny and clones determination, four excellent families and 23 excellent clones were evaluated.
