杉木种子园种子产量大小年周期研究

Studies on On and Off-year Period of Seed Yield of Cuninghamia lanceolata Seed Orchard

从气象学、生态学、生殖生物学角度，研究我国南、中、北带具代表性的3个杉木种子园种子产量大小年的周期、分布年度、形成原因及与气候的关系，提出了调节种子园种子产量大小年的主要技术措施，并根据不同区域种子园大小年发生年份的不一致性，提出调节杉木用种的可行方法。

This paper studied the period, formation cause and annual distribution of on and off-year of seed yield of 3 Cunipghamia lanceolata seed orchards and relationship between yield and climate and proposed main technique measures to regulate seed yield.
