七个砂梨新品种引进筛选研究

Study of the Screening of Seven Sand Pear Cultivars

于2008-2010年调查在贵州地区引进试种的7个砂梨新品种的物候期、植物学特性、经济性状和抗逆性等内容，并进行比较筛选。结果表明：7个梨品种在贵州地区科学管理条件下，从综合比较结果看，新高、金秋梨、高生和湘南等品种的树势分别表现为强、较强、较强和较强；成熟期分别为9月中、下旬、8月下旬至9月上旬、8月中、下旬和8月下旬至9月上旬；平均单果重分别为200．2、225．3、202．5、200．5g；含糖量分别为13．0％、12．8％、13．5g和11．5％；单株产量分别为33．3、31．9、31．6、37．4kg；都表现为适应性强。从综合比较结果看，新高品种表现最好，其次是金秋梨品种，再次是高生品种，由此建议在贵州自然资源条件下加上配套的栽培技术措施，新高等3个品种可在贵州地区适量发展。

In 2008 to 2010 investigated phenological period, botanical characteristics, economic characteristics and resistance, stress resistance etc of seven new varieties sand pear introduce from Guizhou area. Then compared the screening. The results showed that seven pear variety in local science management conditions, from comprehensive comparison results look, Xingao, Jinqiuli, Gaosheng and realize the tree varieties such as strong, respectively for the potential with strong performance, strong and strong; Maturity for September respectively middle and late August to September a,in late August and late August to September a;The average weight of 200. 2 g, respectively 225.3 g, 202.5 g and 200.5 g; Sugar content for 13.0 %respectively, 12.8 %, respectively; 13.5 percent and 11.5 percent The yield, respectively, 33. 3, 31. 9, 31. 6, 37. 4 kg; All performance for strong adaptability. From comprehensive comparison results look, Xingao varieties, followed by best Jinqiuli varieties, once again, was Gaosheng varieties, which suggested that in the local natural resources under the condition of complete technical measures and cultivation, the Xingao three varieties can apply in this area.
