Comparative Study of Canopy Structure Characteristics of High Density Planting Apple (Malus pumila Mill.) Trees Grafting by Dwarf and Standard Rootstocks
摘要
Abstract
[Objective] The purpose was to compare and analyze canopy structure characteristics of high density planting apple trees grafting by dwarf and standard rootstocks, and provide a theoretical support and scientific basis for development of high density planting apple trees. [Method] The characteristics of canopy structure at trunk, 1/4 of canopy, between plants, and between rows of seven-year-old high density planting apple trees grafting by standard and dwarf rootstocks were analyzed by Hemi-View canopy determination and analysis system. In standard rootstocks garden, parental stock was Malus robusta Rehd. . And in dwarf rootstocks garden, base parental stock was Malus robusta Re-hd. , while interstocks was SH40. [Result] The results indicated that standard and dwarf trees had different characteristics of canopy structure. Leaf area index(LAI) of dwarf rootstocks trees was significantly higher than that of standard rootstocks trees at trunk, 1/4 of canopy, and between plants, and the amplitude was 6.6% , 11.0% , 46.8% respectively, however, proportion of visible sky(VisSky) , direct site factor (DSF) , indirect site {aclor( ISF) , global site factor" ( GSF) , direct radiation, diffuse radiation, and every radiation degree indices under canopy were opposite. LAI of dwarf and standard rootstocks trees was 1. 05 and 1. 53 respectively between rows, and there was a significant difference in LAI, meanwhile, the rest indices of dwarf rootstocks trees were higher than that of standard rootstocks trees. [ Conclusion] Suitable rootstock-scion combination should be selected when developing high density apple cultivation, and short branchlet Fuji/SH40/Malus robusta Rehd. is one of its ideal selections.关键词
