寒地苹果矮化密植高效建园技术的研究

在我国寒地以GM_2 56做中间砧 ,进行苹果矮化密植栽培 ,与乔化稀植栽培相比 ,效益可提高 9倍。其关键的建园技术是 :营养面积以每株 6m2 较合适 ;树盘盖膜可提高定植成活率与加快生长 ;先定植砧木后高接生产品种 ,可提高定植成活率 ,促进芽萌发 ,提高嫁接率和早期产量。

Study on the Establishment of High Efficient Fruitery Technique for Cultivation Dwarf and Dense Type Apple in Cold Regin

This paper introduced GM_256 as middle stock to thick dwarf culture for apple,can get 9 times benefit to comparing with thin vigorous culture in cold area of China.The key technology to set up an orchard is:plant one tree per 6 m 2;covering root by film to increase survive rate and facilitate growth;fixed plant stock before inoculate yield variety to increase fixed plant rate,boost bud bourgeoning,increase the rate of graft and forepart yield.
