棚架整形对丰水梨幼树生长结果的影响

Effects of Trellis Reshaping on Growth and Fruiting of Young Trees of Ample Flow Pear

以棚架栽培的丰水梨为试材,通过田间调查和统计分析,研究了定干高度和主枝数对新梢生长量、短果枝数、总枝量及产量的影响。结果表明:主枝数和定干高度对新梢生长量没有影响,主枝数和定干高度之间的互作效应也不显著;主枝数对短果枝数无显著影响,而定干高度对短果枝数有极显著的影响。试验结果表明:主枝数为3、定干高度为90～106 cm在当地实践中是最适宜采用的整形方法。

Taking trellis-cultivated ample flow pear as test material,the effects of heading height and bough number on new shoot growth,number of short fruit shoot,total shoot number and yield were studied through field investigation and statistical analysis.The results showed that the bough number and heading height had no influence on new shoot growth,and the mutual effect between heading height and bough number was not obvious.The bough number had no significant effect on the number of short fruit shoot,but the heading height had extremely significant effect on it.According to the local practices,the optimum reshaping for the young trees of ample flow pear should carry out as follows： bough number was 3,heading height was 90~106 cm.
