【摘要】 通过10多a的连续观测研究,发现油茶新造幼林第2～3年可以开花结果,第4、5年的挂果率达到47．4%～62．3%,单株产果量,单株冠幅和冠幅产果量均呈逐渐递增的趋势．造林后第8～10年进入盛果期．分析了油茶新造幼林挂果的特点和开花结实规律,提出了油茶新造幼林产量测定的基本方法和标准．油茶新造幼林的产量测定以冠幅面积产果量推算时,从第5年开始,连续4a测定单株产果量和单株冠幅,计算平均每m~2冠幅产果量,再按盛果期郁闭度为0．60时的结果冠幅面积来推算油茶成林盛果期的单位面积产量较为适宜,然后根据历年取样测定的鲜果含油率来计算产油量．更多还原

【Abstract】 Based on observation and researches on fruiting characteristics in Camellia oleifera L. for over 10 years,the results show that young plantation will have blossom and fruit in 2～3 years;the ratio of fruiting trees reaches 47.4%～62.3% in 4～5 years,yield per unite and crown projective area rise gradually;it will have get into full fruit period in 8～10 years.The fruiting characteristics and laws of young plantation are analyzed,and methods and standards of yield determination in early stage are put forward.Yield determination should be done in 5- year-old plants,and last for 4 years continually.Based on yield of individual plant,crown projective area and oil content of the fresh fruit determined,yield per unite can be calculated in full fruit period under 0.6 canopy density.更多还原
