The Application of Selenium-enriched Organic Nutritious Fertilizer "Fengxiyuan" in Production of Rape

在油菜蕾苔期和初花期喷施"丰硒源"富硒有机营养肥,可明显提高油菜产量。蕾苔期施用和始花期施用2种方法中,以蕾苔期施用效果较好;蕾苔期以施用2次效果最好。但是施硒处理菜籽含油量有小幅下降,且施用硒肥对提高菜籽油中硒含量无效。

Spraying selenium-enriched organic nutritious fertilizer ＂Fengxiyuan＂ to the rape at bud bolting stage and initial blossom stage can increase the yield of rape obviously.Between the two methods that spraying at bud bolting stage and spraying at initial blossom stage,the effect of spraying at bud bolting stage was better,and if spraying at bud bolting stage twice,the effect was the best.But the oil content in selenium treated rapeseed decreased slightly;meanwhile,applying selenium fertilizer was inefficacy to increase the selenium content in rapeseed.
