甜菜临近收获前浇水,对含糖量影响很大。据调查,临近收获未浇水的甜菜,含糖量高达17.1％,而浇水不久的甜菜含糖量只有14.7％,甜菜糖分下降的幅度一般为2.1—3.0％。浇水后甜菜一个月才能恢复原来的含糖量。同时,后期浇水会引起茎叶贪青徒长,新叶再生,降低含糖率和工艺品质。 Beet near the water before harvest, a great impact on the sugar content. According to the survey, near the unwatering beet harvest, sugar content as high as 17.1%, while sugar beet shortly after watering only 14.7%, sugar beet generally decreased by 2.1-3.0%. Beet watering a month to restore the original sugar content. At the same time, the late watering will cause the stems and leaves to be greedy and leggy, new leaves regenerate, reduce the sugar content and process quality.
