不同施用方式下生物菌肥对榆林地区马铃薯生长的影响
Effects of Different Application Methods on Potato Growth in Yulin Region
摘要
Abstract
To analyze the effectiveness of bio-fertilizer in potato production,three different methods-seed dressing,foliar spraying and root-irrigation-were used in this study,together with three types of bio-fertilizers(mineral potassium fulvic acid,compound Trichoderma agent and Actinomycete agent),to evaluate their effects on the growth and yield of the main potato variety'Qingshu-9'in Yulin region of Shaanxi province.The results showed that seed dressing or root-irrigation with com-pound Trichoderma agent or Actinomycete agent significantly promoted plant height,stem diameter,leaf area and leaf SPAD,and also significantly increased tuber yield and commercial rate.These find-ings suggest that the proper combination of bio-fertilizer type and application method has the potential to enhance potato production in the Yulin region.关键词
