氮磷钾对甜菜硝酸还原酶与亚硝酸还原酶的影响
EFFECT OF NPK ON NR AND NIR ACTIVITY OF SUGAR BEET
摘要
Abstract
The current main sugar beet KWS0143 was applied to investigate effect of NPK fertilizer on NR and NIR activity of sugar beet and discuss the relationship between enzyme activity and yield and quality of sugar beet design.Results showed that the enzyme's activity presented the two-peak curve during the sugar beet growth and development period,The enzyme activity was enhanced with the raising the level of nitrogen.Significant positive or extremely significant positive was found between phosphorous fertilizer and enzyme activity during the middle of sugar beet growth and development.NR activity was significant positive or extremely significant positive correlated with yield and sugar yield at the beginning and end of sugar beet growth and development period.The relationship between NIR activity with yield and sugar yield were extremely significant positive in the middle of sugar beet growth and development period.Enzemes'activity and sugar content were negatively correlated in all the growth and development period.关键词
