播种密度对胡麻田杂草发生及胡麻产量的影响
Influences of Planting Density on Weed Occurrence in Linseed Field and Yield of Linseed
摘要
Abstract
Objective] Clear the influences of planting density on weed occurrence in linseed field and yield of linseed, thereby providing refer-ences for integrated control of weed in linseed field.[Method] Via field experiment, the influences of different planting densities (45, 60, 75, 90, 105 and 120 kg/hm2) on weed occurrence in linseed field and yield of linseed were studied.[Result] Linseed planting density was closely related to weed occurrence in linseed field, the higher of planting density, the lighter of the weed occurrence.Planting density also had a signifi-cant effect on yield of linseed.With the increase of planting density, weed occurrence reduced gradually and the yield of linseed was gradually decreased.The main reason was that the higher of the planting density, the more serious the linseed lodged, and the higher of yield reduction rate of linseed.[Conclusion] By weighing the relationship between planting density and weed occurrence as well as yield component, also con-sidering lodging factor of linseed, the suitable density of linseed planting is 60 kg/hm2 in the central region of Gansu Province.关键词
