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.
Single factor randomized block method was used to study the influence of erectability, seedling height and depth of seedling on the seedling emergence rate, yield, sugar content and yield of sugar beet, The degree had a significant effect on the rate of seedling emergence, yield and yield of sugar, but had no significant effect on the sugar content. When the degree of verticalness was less than 30 °, the effect on seedling emergence rate was significant. When the degree of standing was less than 60 °, The seedling height and seedling depth had a significant effect on the yield and sugar content, but had no significant effect on the seedling emergence rate and the sugar content. When the seedling height and seedling seedling depth were between 1 and 3 cm, Sugar production decreased significantly.
