| 摘 要： | 为油菜生产的提质增效，探究含钾有机水溶肥对油菜生长发育及产量构成的影响，以甘蓝型油菜旺城油8号为材料，采用双因素随机区组设计，设置3个喷施时期（苗期、花期、苗期+花期）和5个含钾有机水溶肥施用量（0、375、750、1125、1500 g/hm2）处理，调查油菜产量性状。结果发现，在苗期或初花期喷施750 g/hm2的含钾有机水溶肥，油菜的株高、根颈粗、生物量等指标较对照组显著增加，两个时期均喷施的处理其促进效果更优。在苗期和初花期均喷施750 g/hm2水溶肥，增加了单株有效角果数和每角粒数，显著提高油菜产量，较对照增加39.07%，产油量增加44.22%。认为可通过在油菜苗期和初花期每公顷各喷施750 g的含钾有机水溶肥，促进油菜的生长发育，提高菜籽产量，增加产油量，提升经济效益。

| Abstract: | To improve the seed yield, foliar spraying of potassium fertilizer was studied to explore the effect of potassium-containing organic water-soluble fertilizer on rapeseed growth and yield. Cultivar Wangchengyou 8 was used as material, with 3 spraying periods （seedling, early bloom stage, seedling + early bloom stage） and 5 potassium-containing organic water-soluble fertilizer application rates （0, 375, 750, 1125, 1500 g） treatments. Two-factor randomized block test was designed. Results showed that, after spraying 750 g potassium-containing organic water-soluble fertilizer at rapeseed seedling or early bloom stage, growth and development indexes （including plant height, root neck thickness, and biomass） were significantly increased. And spraying twice at seedling and early bloom stage had a more significant impact on growth and development than spraying at a single period. Spraying 750 g per hectare at both seedling and early blooming increased the number of effective siliques per plant and seeds number per silique. An increase of 39.07% on seed yield and 44.22% on oil production per hectare were also observed compared with control. By spraying 750 g per hectare at seedling and early blooming stages, plant growth, yield, seed oil, and economic benefits could be significantly increased. |
