摘要
Abstract
The 3×3 optimized fertilization design was adopted on the study of Sugarbeet fertilization in the main Sugarbeet production of Heilongjiang province. The results showed that the optimum rate of nitrogen and potassium for high yield sugarbeet was 90 - 135 kg/hm2 , for phosphorus was 80 - 120 kg/hm2; the optimum ratio of nitrogen, phosphorus and potassium was N;P2O5 :K2O = 1. 11:1:1. 12. Without nitrogen , phosphorus and potassium application, the yield decreased by 33. 8% , 21.1% and 21.6% , respectively. On the synthesized consideration of both yield and sugar content, the best treatment was N2P2K2, that is N 90 kg/hm2, P2O5 80 kg/hm2, K2O 90 kg/hm2 ; compared to CK, the yield increased by 31. 9% , sugar content increased by 1.08 percentage. The study has established three types fertilization models of high yield sugarbeet in three kinds soils.关键词
