【摘要】 黑龙江产区由于近些年来生产上种植的品种单一,严重限制了该区域的甜菜生产,培育和引种新的甜菜品种,对该地区调整种植业结构、发展糖业生产、提高农民收入意义重大。多年的田间试验表明国外品种与当地对照品种相比,有明显的增产优势。采用小区试验的方法,对引进的9个甜菜新品种进行了对比试验。结果表明引进的9个甜菜新品种的块根产量达45.11 t.hm-2～57.6 t.hm-2;产糖量达7 038.03 kg.hm-2～8 851.28 kg.hm-2。其中KWS0413、BETA812、BASTI-ON品种产糖量表现较高。更多还原

【Abstract】 In recent years,the lack of diversity in varieties has seriously limit sugar beet production in Heilongjiang production area.It becomes crucial to cultivate or introduce new sugar beet varieties for adjusting local planting structure,developing sugar production,and increasing farmers’ income.Years of field experiments indicated that compared with local varieties,the overseas varieties can significantly increase yield.In this study,contrast experiments of plots were carried out in 9 sugar beet varieties introduced.The results showed that the yield of root and sugar of 9 introduced beet varieties reached 45.11 t·hm2～57.6 t·hm2,and 7038.03 kg·hm2～8851.28 kg·hm2,respectively.In particular,among the 9 introduced beet varieties,KWS0413,BETA812,and BASTION performed well in sugar yield.更多还原
