摘要:
<正>本文用可见半面树冠球果估测法、球果切开法和标准木法对安徽省山斗杉木种子园结实量进行了研究。结果表明,可见半面树冠球果估测法工作量小,精度较高,至少可以提前3个月预测杉木的结实量。把可见半面树冠球果估测法与球果切开法结合使用,可以预测单株或林分的种子潜在产量。
Abstract:
An investigation in Shandou seed orchard in 1988 showed that both the numbers of cones counted from visible crown and from sample trees could be used to forecast the cone crop of Chinese fir three months ahead of collection, which satisfied the rcquirmcnt of short-term prediction. Counting cone numbers from visible crown gave more accurate prediction with less working load than that from sample trees. Along with cone crop prediction, the numbers of filled seeds exposed by slicing cones longitudinally revealed potential seed crop.
