生姜的营养特性及钾对生姜产量和土壤肥力的影响
The Nutrient Characteristics of Ginger and Effect of Different K Level on Ginger Yield and Soil Fertility
摘要
Abstract
Field experiment was conducted to study ginger (Zingiber officinale Rosc.) nutrient characteristics, yield and soil fertility by different K fertilizer levels.The results showed that ginger nutrient absorption amount was firstly for K.Ginger must absorb N 6.1 kg, P2O5 2.36 kg and K2O 9.4 kg from soil, if its root-stem yield was 1 000 kg.The yield for K3 treatment was the highest, but there was no significant difference in yields between K2 treatment and K3 treatment.We could obtain by linear equation of yield and fertilization that K fertilization for the highest yield was 900 kg · hm-2.Considering the effects of different K levels on nutrient absorption and soil fertility, the optimal fertilizer rate was K2O 750-900 kg · hm-2, the optimal N and K2O proportion was 4∶ 5-4∶ 6.关键词
