甜菜地下部分的块根与地上部分的茎叶之间的功能是否协调,干物质的消耗与积累是否得当,以及生长速度的快慢都会直接影响块根产量和含糖率。为此从一九七四～一九八○年,我们在狼山甜菜试验站连续六年对二十一个品种、品系或组合材料进行了地上部分与地下部分重量比(T/R)(以下称根叶比与产质量相关性)的研究工作。
Whether the function of the tubers in the underground part of the sugar beet and the shoots and leaves in the aboveground part of the sugar beet, the proper consumption and accumulation of dry matter, and the speed of the growth will directly affect the root yield and the sugar content of the roots. For this purpose, from 1974 to 1980, we conducted T / R (T / R) ratio of aerial parts to underground parts for twenty-one cultivars, strains or combinations for six consecutive years at Langshan Beet Experimental Station Hereinafter referred to as the ratio of root to leaf yield and quality) research work.
