摘要：

调查统计了罗田板栗6个不同品种"六月暴"、"中果早栗"、"乌壳栗"、"八月红"、"桂花香"和"玫瑰红"的物候期及结果习性,为板栗品种多指标数量分类提供依据。结果表明:6个板栗品种均在4月上中旬萌芽,萌芽约1周后展叶,展叶约30d后柱头出现且雄花初开,经15～25d左右花期结束,花期结束后果实发育约90d成熟,但"六月暴"少于90d果实即可发育成熟;"八月红"有高结实率、低空苞率,适宜作为良种材料进行大面积推广,但具有高雄雌花序比,故应人工做好去雄,控制合适的雄雌花序比,以提高产量。

摘要：

Phenophases and bearing habits of six kinds of Chinese chestnut varieties that were 'Liuyuebao','Zhongguozaoli','Wukeli','Bayuehong','Guihuaxiang' and 'Meiguihong'in Hubei Luotian were investigated and analyzed,which would provide basic index number for classification of Chinese chestnut varieties.The results showed that,the leaf expansion appeared after it sprout one week later in early or middle April.Then after about 30 days,begun to enter into the flowering.The flowering period would last 15~25 days.The chestnut was mature after fruit development of 90 days since the end of flowering,but the period of 'Liuyuebao' was less than 90 days;'Bayuehong' had a higher maturing rate and a lower empty rate than other varieties,which was suitable for large area promotion.But the proportion of male and female inflorescences of 'Bayuehong' was also higher than others.So artificially control the proportion of the male and female inflorescence to increase production.
