首红苹果早果优质丰产栽培模式研究

Study on Cultivated Model of Early Fruit Good Quality and High Yield in "Red Chief Delicious" Apple

元帅系苹果采用常规栽培方法难以获得早果丰产。选首红为主栽品种 ,红富士和北海道 9号为授粉树 ,建生产园。进行了口字形、田字形、井字形和双田字形 4种不同密度定植、不同高度定干、不同树形、不同整形修剪方法的栽培模式对比试验 ,历时 5年 (1995年— 1999年 )。结果表明 ,采用双田字形密度栽培模式能获得早果、优质、丰产效果。

Normal cultivation of Delicious apple couldn't gain early fruit and high yield. Therefore, the experiments of four cultivated models of'Red chief delicious' were carried out. For five-year experiments, the results showed that the apple trees cultivated as a model of double Chinese word'田'could achieve early fruit, good quality and high yield.
