摘要
对13年生的富士苹果园进行密闭园隔株间伐改造,株行距由2 m×3 m改造成3 m×4 m。结果表明,改造一年后,666.7m2留枝量由207 570个减少到70 235个,果实着色面积达到50%以上的占85%,远远高于改造前的20%,改造后666.7m2产量下降23%;但其产值由改造前的7 150元增加到7 560元,增加幅度为5.7%。
Thirteen-year-old Red Fuji apple orchards were transformed by thinning with the plant-row spacing changed from 2 m×3 m to 3 m×4 m.The results showed that after thinning for one year,the reserved shoot number reduced from 207 570 to 70 235 per 666.7m2.The fruits with the pigmentation area exceeding 50% occupied 85%,which was obviously higher than that（20%） before thinning.The fruit yield per 666.7m2 decreased by 23% after thinning,while the output value increased from 7 150 yuan to 7560 yuan with the increasing amplitude as 5.7%.
