| 摘 要： | 通过田间观察和定期生长分析,明确了冷凉干旱区采用地膜覆盖、灌溉栽培甜菜的各营养生长期的根、叶生长和糖分积累特点,讨论了甜菜生长中心的转移推迟和糖分积累期生长速率、净同化率大幅度降低的原因,提出提早间、定苗和通过水肥调控促进甜菜早发,加速生长中心转移,缩短叶丛快速生长期和改善水分状况,促进块根增长和糖分积累的措施。

| Abstract: | Through the field observation and periodical growth analysis,it was described that characters of root,leaf growth and sugar accumulation of sugar beet which was adopted culture technique of film covering and irrigation in each vegetative growth phase in the cool and dry region,the reasons was discussed that sugar beet growth center was transferred and postponed,the growth velocity of sugar accumulation period and net assimilate rate were lowered significantly,the methods were brought up that seedling thinning and setting early and control the water and fertilizer to promote sugar beet to appear early and accelerate the growth center to transfer,shorten the leaf cluster quickly growing period and improve the water condition to promote root to grow and sugar to accumulate. |
