摘要
果树栽培中,利用环剥中断有机物向下运输,从而阻止了有机物向下运输,改善中上部枝叶的营养状况,有利于座果和果实膨大。试验以黑叶荔为材料,分别进行半圆环剥、螺旋环剥、及两道环剥等措施的处理,观察不同环剥方式对黑叶荔成花率、花期日开花比率、座果率、百果重的影响。试验结果表明:半环剥成花率最高,达到79.6%,花期持续时间达11d,座果率以对照最高,综合权衡以两道环剥处理的成花率、座果率和果重较理想。
In fruit raising, use band girdle interrupt organic matter downward transportation, thus the impediment organic matter downward transportation, in the improvement upside the branches and leaves nutrition condition, is advantageous in the place fruit and the fruit expands.
