密闭苹果园树体优化改造对树体结构及产量品质的效应
Effects of Canopy Improvement on Tree Structure, Fruit Yield and Quality in Airtight Apple Orchard
摘要
Abstract
Using Fuji apple tree as material,the effects of canopy improvement on tree structure,population structure,fruit yield and quality were studied in airtight apple orchard.The results showed that,branches per 666.7m2 decreased from 105 392 to 78 288 after canopy improvement,decreased by 25.7％ ; the proportion of short branches to total branches increased from 28.3％ to 31.3％,increased by 3.0 percent points,while that of leafage branches increased from 25.5 ％ to 26.3 ％,increased by 0.8 percent points.The population structure was significantly improved.Compared with airtight apple trees,the yield of improved apple trees decreased by 15.8％,but the single fruit weight,colour index,smoothness index,flesh hardness and soluble solid content increased obviously.关键词
