野生榛林一序多果现象的调查与分析

Investigation of Wild Corylusheterophylla Plantation with More Fruit in One Infructescence

通过在抚顺县设立试验区,对野生榛林一序多果情况进行了调查和统计,结果表明：一序多果是野生榛子结实的基本特性;在目前经营水平有限的情况下,应适当控制一序5果及5果以上果序;在坚果膨大期,对多果序进行人为处理,一序保留3~4果较为适宜。

Experiment area were established in Fushun County,condition of wild Corylus heterophylla plantation with more fruit in one infructescence was investigated.Result shows that more fruit in one infructescence is basic characteristics for wild Corylus heterophylla;in the current limited operating level,five over fire fruit in one infructescence should be properly controlled;in the stage of enlargement of nuts,manual treating with multi-infructescences,three–four fruit in one infructescence is optimal.
