盐碱土壤施用不同生物有机肥对大麦生长和产量的影响
Effects of Different Bio-organic Fertilizers on the Growth and Yield of Barley in Saline-alkali Soil
摘要
Abstract
A field experiment was conducted to assess the effects of three microbial organic fertilizers on the growth and yield of the bar-ley variety 'Flower 22.As a result,compared with the conventional fertilizer application method adopted by local farmers (regularly ap-plying N-fertilizers,but without applying organic fertilizers),application of each of the three tested microbial organic fertilizers in-creased tiller number,the number of productive panicles,and 1000 -grain weight of barley;but decreased barley spike number,ear length,and plant height.Relative to regular application of N-fertilizers alone,combining them with humic acid fertilizer increased bar-ley yield by 8.54%.In two treatments,N-fertilizers (applied at a rate 10% lower than the recommended rate)were combined with humic acid fertilizer or wormcast organic fertilizer,leading to increases in barley yield by 0.22%and 1 .43%,respectively.Hence,it is feasible to reduce application rate of chemical fertilizers by combining them with microbial organic fertilizers.关键词
