苹果幼树调冠改形增效关键技术研究

Key Technology Research of Increasing Efficiency about Adjustable Crown Modification to Apple Young Tree

为了探讨苹果幼树调冠改形增效的关键技术,通过2008~2010年的系统研究,苹果幼树进行＂提干高、控比例、大开角、疏竞争、定主枝、调枝量、建枝组、限高度＂8项关键技术研究,并对其技术进行集成,提出了苹果幼树由＂自由纺锤形＂改成＂雪松形＂的高光效新树形,并探讨出调冠改形后树体的光分布指标;研究出苹果树调冠改形过程中＂土壤施灌氨基酸液体肥料、落头时留保护桩及涂抹伤疤愈合剂＂的3项配套技术。通过调冠改形关键技术的研究,解决了原来树体结构不合理,光照条件差,产量低,质量差等诸多问题,并对改善果园生态环境,丰富果品市场,增加出口创汇能力,促进果业的可持续发展,起到了巨大的推动作用。

In order to study on the key technology of increasing efficiency about adjustable crown modification to apple young tree. Through systematic research from 2008 to 2010, researched the key technology about＂ Im- prove the trunk, Control ratio,Large open angle,Thin Comp of branches, establishment of branches, the height limit＂ of Put forward the new tree shape of high light efficiency from pie young trees, and discussed the light distribution index porting technology In the process of no acid liquid fertilizer, Stay pro environment of orchard, rich fru C etitive branch, selected branch,adjust the quantity apple young trees, and its technology integration, ＂Freedom spindle shape＂ to ＂Cedar Shape＂ on ap- of apple tree after adjustment. Researched 3 sup- adjustable crown modification of apple young tree, Soil[ and irrigating ami- ~d pile falling head,Painting scar healing agent. To improve the ecological market, increasing export capacity, promote sustainable development of fruit industry, has played a great role in promoting.
