Effect of Different Fertilization Rates on Yield and Quality of Brassia campestris in Plateau
-
摘要: 为探究不同的施肥处理对贵南县高原白菜型油菜农艺性状及产量的影响，以北油4号为供试材料，设置T1(无氮区）、T2（无磷区）、T3（无钾区）、T4(氮磷钾区）、T5(无肥区）5个处理开展田间试验。试验结果表明，北油4号品种无论是单独缺少氮肥、磷肥、钾肥还是同时缺少3种元素的肥料，都会造成产量和品质的下降，且从3种元素来看，缺氮造成油菜减产幅度最大。因此，针对本地北油4号高原白菜型油菜主栽品种，要注重氮磷钾肥的科学施用，以提高油菜产量和品质。Abstract: In order to explore the effects of different fertilization treatments on agronomic traits and yield of plateau Brassia campestris in Guinan County, Beiyou No.4 was used as the test material and 5 treatments were set up to carry out field experiments. The results showed that the lack of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer alone or the lack of three elements at the same time would lead to the decrease of yield and quality of the variety, and from the three elements, the lack of nitrogen caused the largest yield reduction of rape. Therefore, for the local Beiyou No.4 plateau Brassia campestris main cultivar, should pay attention to nitrogen, phosphorus and potassium fertilizer, especially the scientific application of nitrogen fertilizer, in order to improve the yield and quality of Brassia campestris.
