景电灌区保水剂施用量对甜瓜产量及水分利用效率的影响
Effects of Different Water-holding Agent Application Rates on the Yield and Water Use Efficiency of Melons in Jingdian Irrigation Area
摘要
Abstract
To investigate the regulatory effects of water-holding agents on the growth and development and water-use efficiency in melons so as to provide a theoretical basis for the scientific application and promotion of water-holding agents,the effect of 3 different water-holding agent application rates(60 kg/ha,75 kg/ha,and 90 kg/ha)on the growth,development,yield and water-use efficiency in melons were investigated under field conditions with melon as the test material and no water-holding agent as the control(CK).Results showed that the application of water-holding agent significantly promoted the elongation of vines,thickening of stems and the increase of leaf area index of melons at all fertility stages.The melon treated with 90 kg/ha of water conservator had the highest vine elongation,stem thickening and leaf area index at all fertility stages,and the highest melon yield and water utilization efficiency,which were 11.0%and 22.8%significantly higher than that of CK,respectively.Considering the growth and development of melon plants,yield and water utilization efficiency,promoting the application of water retaining agent can be a technical solution for drought and water conservation in Jingdian Irrigation District,and the optimum application rate of water retaining agent is 90 kg/ha.关键词
