伊春地区矮丛蓝莓越冬防寒方法比较试验

为探讨矮丛蓝莓越冬防寒的有效方法，以五年生矮丛蓝莓品种美登为试材，研究实心埋土、空心埋土、简易防寒和堆雪防寒4种防寒方式时越冬性、植株长势和产量的影响。结果表明：实心埋土防寒法效果最好，基本没发生抽条，空心埋土防寒法次之，而简易防寒法和堆雪防寒法无效果，抽条率100％；空心埋土法株丛长势最好，株高达到46．7cm，其次是实心埋土株高43．7cm；实心埋土产量最高，单株可达359g。因此，实心埋土防寒法的产量高、长势壮、方便简单，是高寒地区理想的蓝莓越冬防寒方法。

The Comparison Test of Cold-resisting Cultivation Methods of Lowbush Blueberry in Yichun Area

In order to explore the effective approach of cold-resisting,taking five years life of lowbush blueber ties cuhivars Blomidon as materials,the influence of solid buried soil,hollow buried soil, simple cold proof and snowdrift cold-proof were studied on overwintering, plant growth and yield of blueberry. The results showed that the wintering cold-resisting method of cold proof in solid buried soil was the best and had no sprout phe nomenon basically,while the hollow buried soil followed,the methods of simple cold-~proof and snowdrift cold proof had no effect, pumping rate was almost 100%; the plant grew best in hollow buried soil, the highest height was as high as 46.7 cm followed by solid buried soil,the maximum height reached 43.7 cm;solid buried soil got the highest yield and tile highest individual plant was up to 359 g. As a result, the method of cold-proof in solid buried had the highest yield and the strongest growth,it＇s the ideal buried soil cold-resisting way with simple and convenient.
