杂交油菜沣油520不同栽培模式的施肥效果研究

Fertilization Effect of Hybrid Rape Fengyou 520 with Different Cultivation Mode

为了进一步研究杂交油菜沣油520在不同地区各种栽培模式下的施肥方案,在湖南安乡、桃源、衡阳3个试验点进行2因素3重复的随机区组试验。结果表明:育苗移栽可缓解前作双季稻的季节搭配矛盾,获得油菜高产;直播栽培只要适当提早播期、合理施肥同样可以获得高产。同时,施肥量是油菜丰产的重要因素,采用45%(15∶15∶15)的复合肥,棉田总用肥量35～40 kg/667m2,稻田总用肥量50 kg/667m2左右为宜。

In order to research the fertilization scheme of hybrid rape Fengyou 520 in different cultivation mode in different regions,two factors three repeated randomized trials were conducted in Anxiang,Taoyuan and Hengyang in Hunan.The results showed that seedling transplanting could alleviate the season collocation contradiction of double cropping rice,and rape got a high yield.Fertilizer rate was an important factor of rapeseed fertility.Using 45%（15∶15∶15） compound fertilizer,the appropriate fertilizer was 525～600 kg/hm2 in the cotton fields,and 750 kg/hm2 in the rice fields.
