荞麦不同播种方式和种植密度对田间杂草及荞麦产量的影响

Effects of Different Sowing Methods and Planting Densities of Buckwheat on Weed Occurrence and Buckwheat Yield

通过荞麦的播种方式和种植密度来进行杂草管理。结果表明,在同一播种方式下随着种植密度的增加杂草株数和鲜重减少,荞麦产量增加,但荞麦各农艺性状的表现值在不同播种方式和种植密度下没有显著差异;另外,撒播的荞麦抑制杂草能力及产量都大于条播和塘播。可见,在粗放管理条件下撒播可抑制杂草提高产量。

In this study,weed management was conducted by buckwheat sowing method and planting density.Under the same sowing method,as the planting density increased,the number and fresh weight of weeds decreased,and the yield of buckwheat increased.However,there were no significant differences in the values of agronomic traits of buckwheat under different sowing methods and planting densities.In addition,the weed control ability and buckwheat yield of broadcast sowing were higher than those of drill and pond sowing.Broadcast sowing could supress weeds and increase yield under extensive management.
