【摘要】 通过对2种不同类型甜菜各设5个密度处理[多胚种行距50cm×(18cm、21cm、24cm、27cm和30cm);单胚种行距50cm×(12cm、15cm、18cm、21cm和24cm)]的11个生理性状的测定分析,得出试验研究结果:在新疆奇台产区,种植多胚种甜菜的最佳密度应该控制在94500株/hm2(株行距21cm×50cm)左右;种植单胚种甜菜,密度控制在111000株/hm2(株行距18cm×50cm)左右可以获得较高的产量和含糖率。更多还原

【Abstract】 Eleven physiological character of two different types of sugar beet were determined and analyzed under 5 density treatments [polygerm variety, rowledge 50 cm ×(18 cm, 21 cm, 24 cm, 27 cm and 30 cm);monogerm variety, rowledge 50 cm ×(12 cm, 15 cm, 18 cm、21 cm and 24 cm)]. The experimental research results showed that Qitai area optimum planting population of polyembryonic seeds was 94500 plants/ha(row and plant spacing 21 cm × 50 cm). And the best planting population of monogerm seeds was 111000 plants/ha(row and plant spacing 18 cm × 50 cm) in Xinjiang. High yield and sugar content could be obtained in this population.更多还原
