福建卫闽杉木种子园丰产技术研究

Study on High-Yield Technique of seed Orchard of Cunninghamia lanceolata in Weimin Forest Center of FuJian

通过疏伐、合理施肥、施用农用赤霉素、满果粉、多效唑，以及人工辅助授粉等综合丰产技术措施，使该种子园试验区（不包括对照）１９９４年平均每公顷产种子达９７．３０５ｋｇ，为以往历年平均产量的８．６７倍，比当年对照区增产球果８６．６％，增产种子９８．７４％。１９９１～１９９４年，对９９个无性系进行产量调查，结合该场的子代鉴定结果，从中初筛出优质高、中产无性系２３个，并建立采穗圃。

Through complex high - yield techniques like thinning, rational fertilization, application ofGibberellin. 'Manguo' power and pp330. artificial Pollination, the average seed yield of the seed orchardin 1994 reached 97. 305kg/hm2, which was 8. 67 times of that in the years past. Cone and Seed of thisorchard incerased by 86. 6% and 98. 74% respectively than the control. From 1991 to 1994, after investigationson yield of 99 clones. 23 fine and high - yield clones were selected according to yield and progeny - testing.
