摘　　要：为了提高渭北旱塬苹果园的经济效益,以盛果期乔砧密植园为对照,将相同树龄的矮砧密植园和半矮化砧密植园的留果量保留为同一水平,监测不同砧穗组合密植园的树体生长状况。结果表明:矮砧密植园和半矮化砧密植园的叶面积指数较乔砧密植园分别降低30.47%和23.98%,叶片蒸腾速率分别降低7.56%和5.84%,叶片光合速率则分别提高17.36%和9.88%。矮砧密植园、半矮化砧密植园的树体生长量小,但果实产量与乔砧密植园的基本一致。矮砧密植园、半矮化砧密植园的果园产值较乔砧密植园分别提高了8.58%和7.43%。说明矮砧密植和半矮化砧密植可提高果园产值,因此渭北旱塬应积极推广苹果矮砧密植和半矮化砧密植栽培。In order to improve the economic benefits of the apple orchard in Weibei dry plateau,taking the apple orchard with vigorous stock dense planting at the full bearing age as a control,the bearing fruit number of dwarfing stock dense planting and semi-dwarfing stock dense planting orchards were kept to the same with the vigorous stock dense planting orchard,and the tree growth status in different dense planting orchards with different stock-scion combinations was monitored.The results showed that the leaf area indexes of the dwarfing stock dense planting and semi-dwarfing stock dense planting orchards were 30.47%and 23.98%lower,and the leaf transpiration rates were 7.56%and 5.84%lower,but the leaf photosynthesis rates were 17.36%and 9.88%higher than that of the vigorous stock dense planting orchard,respectively.The tree growth in the dwarfing stock dense planting and semi-dwarfing stock dense planting orchards was smaller,but the fruit yields were basically consistent with that in the vigorous stock dense planting orchard.The fruit output value of the dwarfing stock dense planting and semi-dwarfing stock dense planting orchards increased by 8.58%and 7.43%,compared with that of the vigorous stock dense planting orchard,respectively.The above results indicate that the dwarfing stock dense planting and semi-dwarfing stock dense planting patterns can increase the production value of apple orchard,so the two dense planting patterns should be popularized inWeibei dry plateau.
