摘要: 为了探讨包膜复混肥的应用效果。采用多点试验,研究了包膜肥对油菜产量、养分积累以及土壤养分形态的影响。结果表明,与普通复混肥相比含量,全量包膜复混肥能够极显著提高油菜籽粒产量,平均产量可达2 501.00 kg/hm2,增产率平均达到13.72%;可以显著提高油菜茎秆产量,对根产量有一定程度的提高,角果皮产量基本不受影响;包膜复混肥能够促进油菜养分在后期快速积累,主要表现在氮和钾的积累方面,磷的积累量没有表现出较好的效果;包膜复混肥养分释放在衡阳表现较好,湘潭次之,宁乡最差;氮肥效果在衡阳地区与油菜生长相协调,钾肥效果在湘潭地区得到体现,磷肥没有表现出缓控释肥的效果;土壤养分浓度与土壤温度是造成包膜复混肥养分释放差异的重要原因。此外,N-P2O5-K2O(12-6-7)的油菜专用肥进行包膜后,能够提高油菜的产量,但在不同的地方使用效果不同,其中磷的养分释放不能与油菜生长相协调,必须通过大配方小调整或改变包膜技术来实现缓控释肥的目的。

Abstract: To investigate the effects of coated mutual mix fertilizer application.The effects of coated mutual mix fertilizer on rapeseed yield,nutrient accumulation and soil nutrient morphology was researched by multi-region field plot experiments.Compared with ordinary mutual mix fertilizer,coated mutual mix fertilizer could significantly improve the yield of rapeseed,and the average yield reached 2 501.00 kg/ha,reaching to 13.72% compared to an average increase rate,it also could significantly improve the yield of rapeseed stalk,and improve the root yield to some extent,while the pericarp yield were not affected;coated mutual mix fertilizer promote nutrients accumulation rapidly in the latter period,mainly presenting in the accumulation of nitrogen and potassium and phosphorus accumulation did not show good results;Coated mutual mix fertilizer nutrient releasing performed better in Hengyang,followed by Xiangtan,Ningxiang was worst,nitrogen releasing in Hengyang area coordinated with rape growth,the effect of potash was reflected in Xiangtan region,phosphate showed no slow-release fertilizer effect;The important reasons that caused the differences in nutrient release of coated fertilizer soil nutrient concentrations and soil temperature.This experiment studies had shown that N-P2O5-K2O(12-6-7)fertilizer for canola envelope could improve the yield of oilseed rape,but the effects was different in different places,phosphorus nutrient releasing couldn't coordinated with rape growth,to achieving the purpose of slow-release fertilizer,small adjustments to large envelope recipe or changing technology must be taken.

Key words: Coated mutual mix fertilizer, Oilseed rape, Yield, Nutrient accumulation, Patterns of soil nutrients
