寒地苹果矮化密植高效建园技术的研究

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

摘要:

在我国寒地以GM-256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6 m²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。

Abstract:

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 m²;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.
