Abstract
Nitrogen application has significant effect on the accumulation and distribution of dry matter and yield and quality of sugar beet plant.Study was made on the effect of the five nitrogen levels(N0、N90、N180、N270、N360) on the leaf area and LAI and accumulation and distribution of the dry matter and yield and quality of sugar beet plant with the material of KWS2409.The results showed that the population's middle and deuteric leaf area index,the population's dry matter accumulation and water content of root tuber increased with increment of nitrogen supply,while the root cap ratio and the sugar content of harvest decreased significantly.With the nitrogen supplied increasing the root yield and sugar yield increased first then decreased.The nitrogen applied for the highest sugar yield(13 892.64 kg/hm2) is 180 kg/hm2,the root yield is 82 609.63 kg/hm2,the sugar content is 16.83 percent.The maximum increment of root yield is 38.2 percent higher than those without fertilizer application,the maximum increment of sugar yield is 26.9 percent higher than those without fertilizer application.Achieving high yield and high sugar content in sugar beet depends mainly on the soil fertility conditions.
