摘要:
采用单因素随机区组试验设计，在滴灌条件下，对北疆复播大豆不同密度茎节性状、荚粒时空分布以及产量构成因素等进行了研究。结果表明：单株荚数、单株空荚数、单株粒数随密度的增大而降低；主要改变了荚粒在上层和下层的分布比例，而对中层荚粒所占比例影响很小。着粒密度则随着密度的增加而降低，最低密度处理较最高密度处理着粒密度提高了63.16%。随着密度的增大，株高增高，茎节节间长度呈增大趋势，而茎粗呈现减小趋势。产量随着密度的增加呈现开口向下的抛物线变化趋势。试验设计条件下以52.5万株·hm-2密度处理的产量最高，为3 205.04 kg·hm-2，与其他处理差异均达到了极显著水平(P＜0.01)
Abstract:
The effects of planting density on the stem elongation,distribution of pod and seed,yield and yield components of summer soybean under drip irrigation were studied.Treatments were established following one factor and randomized block design.The result showed that the number of pods,seedless pods and seeds per plant declined with the increasing density.The effect of planting density on variations of the number of pods and seeds were significant in upper and lower layers,but not in middle layer.With the increasing of planting density,plant height and internode length increased,while the grain density and stem diameter decreased.The difference in grain density was up to 63.16% due to plant density.The yield showed a downward parabola against planting density.It found that 5.25×105plants per hectare had the highest yield of 3 205.04 kg·ha-1,which reached a very significant difference(P<0.01)compared to the other treatments.
