采用单因素随机区组的方法,研究了甜菜纸筒纸钵苗直立度、露苗高度和埋苗深度对缓苗率、产量、含糖率和产糖量的影响规律.试验结果表明:直立度对缓苗率、产量和产糖量有显著影响,对含糖率无显著影响;当直立度小于30°时,对缓苗率影响显著;当直立度小于60°时,产量和产糖量急剧下降;露苗高度和埋苗深度对产量和产糖量有显著影响,对缓苗率和含糖率无显著影响;当露苗高度和埋苗深度在1~3 cm时,产量和产糖量显著降低.
The effects of perpendicularity, nudity height, burying height of paper pot seedling on seedling percent, yield, sugar content and sugar yield of sugar beet were analyzed by a single factor randomized block design. The results show that the seedling perpendicularity has significant influence on seedling percent, yield and sugar yield, while it has no influence on sugar content. When perpendicularity of seedling is less than 30°, the seedling perpendicularity has significant influence on seedling percent. When the seedling perpendicularity is less than 60°, yield and sugar yield decrease sharply. The nudity height and the burying height have marked effect on yield and sugar yield with slight influence on seedling percent and sugar content. When nudity height and burying height of seedling are at the range of 1 to 3 cm, yield and sugar yield decrease significantly.
