摘要
通过观察调查，明确了“韶栗１８”板栗的基本生物学特性，并绘制出了技梢生长、总苞膨大曲线；明确了结果母枝的长度、粗度与结栗苞数有极显著的相关关系，其ｒ值分别为０．８４５９、０．８４１６；结果母枝的顶芽和次顶芽所抽生结果枝的结苞数是构成树体产量的重要组成部分；目前栽培中的主要问题在于空苞率高，二、三次花不结实，出籽率低，落苞严重。进一步提高“韶栗１８”产量构成指标，关键在于提高实苞率，每栗苞着栗粒数。
This study revealed the biological characteristics, the dymanics of shoot growth and bur expansion of the chestnut variety “Shaoli 18”.The length and diameter of bearing mother branches was significantly positively correlated to bur numbers, with a correlation coefficients of 0.8459, and 0.8416, respectively. The number of burs on the fruiting branches from top and sup-top buds on bearing mother branches was a major component of yield. The main problems in chestnut cultivation included: ① as high as 45.3% empty burs; ② failure of secondary and tertiary flowers to fruit; ③ low bur-setting rate; ④large proportion of burs dropped. In order to improve the yield components of 'Shaoli', it was a key measure to increase the percentage of full burs and the number of grains in a bur by means of arranging proper pollenizers and improving nutritional status.
