采用小区定量播种不同密度的节节麦种子(Aegilops squarrosa L.)进行对小麦产量影响试验,在小麦收获时进行小区实际产量测定。试验结果表明,节节麦各密度处理与空白对照处理间差异均达到极显著水平。密度50株节节麦/m2,可造成小麦减产19.12%;100株节节麦/m2,可造成小麦减产27.50%;150株节节麦/m2,可造成小麦减产41.22%;200株节节麦/m2,可造成小麦减产47.26%。并提出防除对策。 In this experiment, Aegilops squarrosa L. was used to sow seeds of different density to test the wheat yield. The actual yield of the plot was measured at the time of wheat harvest. The results showed that there was a significant difference between the treatments of all treatments and the blank control treatments. Density of 50 nodules of wheat / m2, can cause 19.12% reduction of wheat; 100 nodal wheat / m2, can cause 27.50% reduction of wheat; 150 nocturnaatum / m2, can cause wheat yield reduction of 41.22%; 200 nodules Wheat / m2, can cause wheat yield reduction of 47.26%. And put forward control measures.
