摘要
为探讨不同株行距建园对梨树体结构的影响,调查了不同株行距乔化‘新梨七号’细长纺锤形树体和群体结构参数。结果表明,株行距增大,干周增大,主枝开张角度增大,结果枝比例增大,5年生乔化细长纺锤形‘新梨七号’的适宜优质丰产株行距以1.5 m×4.0 m或2.0 m×4.0 m为宜。
In order to investigate the effects of different plant row spacing on pear tree structure,the slender spindle tree structure parameters of Xinliqihao with different plant row spacing were investigated.The results showed that with the increase of plant row spacing,the stem circumference,the opening angle of main branches and the proportion of fruiting branches increased.The suitable row spacing for high quality and yield of 5-year-old'Xinliqihao'with slender spindle tree structure was 1.5 m×4 m or 2 m×4 m.
