优质高产“Y”形栽培梨园树体群体结构参数调查

Investigation of pear tree structure parameters of high yield and quality of “Y” shape pruning mode

为探讨在泰安地区自然条件和管理技术水平下,"Y"形栽培梨园合理的树体群体结构参数,对优质高产"Y"形试验梨园的树体和群体结构进行了调查。结果表明,"Y"形‘王秋’梨园盛果初期667 m^2产量为2 550 kg时,枝量约为3.2万条,树体枝类组成以短枝为主,占总枝量的80.1%,其余依次为中枝、长枝、发育枝。"Y"形‘秋月’梨园盛果初期667 m^2产量为2 875 kg时,667 m^2枝量约为3.4万条,树体枝类组成以短枝为主,占总枝量的75.6%,其余依次为中枝、长枝和发育枝。"Y"形‘新高’梨园盛果期667 m^2产量为3 000 kg时,枝量约为3.7万条,树体枝类组成以短枝为主,占总枝量的82%,其余依次为长枝、中枝、发育枝。

In order to study the pear tree structure parameters in Taian area natural conditions and technical level of management, high yield and quality of Y shape pruning mode pear tree were investigated. The results showed that the quantity of branches of ‘Oshu' pear garden is about 32 thousand which was high density planting of Y shape pruning mode with the yield of 2 550 kg/667 m2. The total amount of short branches was 80.1%, followed by middle branches and long branches, development branches. The quantity of branches of ‘Qiuyue' pear garden is about 34 thousand which was high density planting of Y shape pruning mode with the yield of 2 875 kg/667 m2. The total amount of short branches was 75.6%, followed by middle branches and long branches, development branches. The quantity of branches of ‘Niitaka' pear garden is about 37 thousand which was high density planting of Y shape pruning mode with the yield of 3 000 kg/667 m2. The total amount of short branches was 82%, followed by middle branches and long branches, development branches.
