播种量对引黄灌区麦茬复种饲料油菜生长性状的影响
|
摘要
在引黄灌区麦后复种条件下,以饲料油菜品种华油杂62号为材料,通过田间试验,研究低播种量A1 (7.5kg/hm~2)、中播种量A2(15.0 kg/hm~2)、中播种量A3(22.5 kg/hm~2)、高播种量A4(30.0 kg/hm~2) 4种播种量处理对其株高、茎粗、叶绿素含量(SPAD)、叶鲜质量和干质量、茎鲜质量和干质量、鲜草产量、叶面积相对生产率、净同化率的影响。结果表明:低播种量处理有利于饲料油菜干物质的积累;A2、A3处理的鲜草产量显著高于A1、A4的产量;中播种量处理的饲料油菜叶、茎的鲜质量和干质量日增长量均具有优势。综合考虑,引黄灌区饲料油菜较适宜的播种量为15.0～22.5 kg/hm~2。
Under the condition of multiple cropping after wheat in irrigation area of Yellow River, using Huayouza 62 as material, field experiments were conducted to study the effects of four sowing treatments on plant height, stem diameter,chlorophyll content(SPAD), fresh and dry quality of leaves, fresh and dry quality of stems, fresh grass yield and leaf area on relative productivity and net assimilation rate,including low sowing A1(7.5 kg/hm~2), medium sowing A2(15.0 kg/hm~2), medium sowing A3(22.5 kg/hm~2), high sowing A4(30.0 kg/hm~2). The results showed that low sowing rate was beneficial to the accumulation of dry matter in forage rapeseed; fresh grass yields of A2 and A3 treatments were significantly higher than that of A1 and A4 treatments; fresh and dry quality of leaf and stem of forage rapeseed treated with medium sowing rate had advantages in daily growth. Considering comprehensively, the suitable sowing rate of forage rapeseed in irrigation area of Yellow River was 15.0-22.5 kg/hm~2.
