以湘杂油763为供试材料,研究了不同肥料运筹方式对冬油菜产量和部分农艺性状的影响。结果表明:氮肥运筹方式对油菜生长的影响较大,以基肥:苗肥:薹肥=5:2:3处理的籽粒产量最高,其次是基肥:苗肥:薹肥=6:2:2处理,基肥:苗肥:薹肥=10:0:0处理的产量最低,其差异达到了显著水平,单株角果数、每角果粒数、绿叶数、茎粗、最大叶长和叶宽、叶片叶绿素含量等指标也有类似的变化趋势,而氮肥运筹方式对千粒重的影响不显著。磷肥和钾肥运筹方式对油菜生长的影响较小,在不同磷钾肥运筹方式下籽粒产量、产量构成因素、茎叶性状均没有显著差异。在本试验所设的8种处理中,以氮肥的基肥:苗肥:薹肥=5:2:3、磷肥和钾肥的基肥:苗肥:薹肥=10:0:0处理和氮肥的基肥:苗肥:薹肥=5:2:3、磷肥的基肥:苗肥:薹肥=6:2:2、钾肥的基肥:苗肥:薹肥=10:0:0处理的籽粒产量并列最高。
The effects of different manure application methods on the yield and some agronomic characters of winter rape were studied using Xiangzao-763 as test material. The results showed that nitrogenous fertilizer had a great effect on the growth of rapeseed. The yield of grain was the highest with basal fertilizer: seedling fertilizer: sedge fertilizer = 5: 2: 3, followed by basal fertilizer: seedling fertilizer: sedge fertilizer = 6: 2: 2 , Basal: Miao: sedge fertilizer = 10: 0: 0, the lowest yield, the difference reached a significant level, the number of pods per plant, the number of pods per leaf, the number of green leaves, stem diameter, maximum leaf length and leaf width , Leaf chlorophyll content and other indicators also have a similar trend, and nitrogen fertilizer operation on the impact of grain weight is not significant. Phosphorus and potassium fertilizer had less effect on the growth of rapeseed. There were no significant differences in grain yield, yield components and stem and leaf traits under different phosphorus and potassium fertilization methods. In the eight treatments set in this experiment, the basal fertilizer with nitrogen fertilizer: Miao: sedge fertilizer = 5: 2: 3, the basal fertilizer for phosphate and potassium: Miao: sedge fertilizer = 10: 0: 0 The basal fertilizer : Seedling fertilizer: sedge fertilizer = 5: 2: 3, basal fertilizer of phosphate fertilizer: Miao fertilizer: sedge fertilizer = 6: 2: 2, basal fertilizer of potash fertilizer: Miao fertilizer: sedge fertilizer = 10: 0: .
