为配合杂交油菜品种的推广应用,集成云南杂交油菜配套栽培技术,组织了云南省5个不同生态产区,开展杂交油菜种植密度、施肥量以及施肥方法对产量的影响研究。结果表明,不同生态地区、种植密度及磷肥用量3个因素极显著影响小区产量,同时各地区油菜产量与种植密度、氮肥用量之间存在交互作用。在一定范围内增加种植密度和磷肥用量有助于提高小区产量,但是过大的种植密度和磷肥用量有降低小区产量的趋势。通过极差和方差分析得出各地区的最优处理组合。
In order to promote the popularization and application of hybrid rapeseed varieties, Yunnan hybrid rapeseed cultivation techniques were integrated, and five different ecological producing areas in Yunnan Province were organized to study the effects of planting density, fertilizer amount and fertilization method on the yield of hybrid rape. The results showed that the planting density and the amount of phosphate fertilizer significantly affected the yield of different plots in different ecological regions. At the same time, there was interaction between rapeseed yield, planting density and nitrogen fertilizer dosage in different regions. Increasing the planting density and the amount of phosphate fertilizer within a certain range will help increase the yield of the community, but the excessive planting density and the amount of phosphate fertilizer have the tendency to reduce the yield of the community. Through the range and variance analysis, the best combination of treatments in different regions is obtained.
