水肥耦合对不同生育时期大麻株高及生物量的影响
Effect of Water and Fertilizer Coupling on Height and Biomass of Hemp at Different Growth Stages
摘要
Abstract
In order to investigate the effect of water-fertilizer coupling on the growth of hemp,Yunma No.1 hemp was treated with 12 water and fertilizer coupling treatments at different growth stages with pot experiment,and the plant height and biomass of hemp were measured.The results showed that the biomass and plant height of hemp in mature period was highest under group 9 (Water 45%,N 0.267 g/kg,P 0.100 g/kg,K 0.067 g/kg) and group 7 (Water 45%,N 0.133 g/kg,P 0.133 g/kg,K 0.100 g/kg) respectively.Effect of water effect on plant height and biomass of hemp during all growth periods was more than the effect of fertilizer.In mature period,the effect on biomass of hemp were,in order,water >nitrogen >phosphorus >potassium,and the effect of plant height were,in or-der,water >phosphorus >potassium >nitrogen.Reasonable fertilization could improve the water utilization rate of hemp,enough water should been provided under the condition of fertilization.关键词
