【摘要】 经对 2 4个板栗新品系幼树的发枝结果习性进行观测 ,结果表明 ,新品系平均结果枝占当年萌发枝的 5 0 %以上 ,且连续结果性能好 ,达到国家板栗丰产选种标准。对 2 4个板栗新品系幼树 1年生健壮枝作轻剪、中剪、重剪和不剪 (缓放 ) 4种修剪方法的试验 ,结果表明 ,轻剪能显著促进幼树发枝和座果 ,中剪和缓放次之 ,重剪结实差 ,发枝少而壮。更多还原

【Abstract】 The shooting and bearing habit of 24 new strains of Castanea miomollissma saplings were observed The results showed over 50% of annual shoots fruited,which attained the national standard of high yield Pruning experiment were also carried out on one year old healthy shoot of these 24 new strains The experimental results implied that slight pruning promoted shooting and fruit setting significantly,followed the effect of moderate pruning and no pruning,however heavy pruning affected the shooting and fruiting更多还原
