Effect of Special Fertilizer Dosage on the Yield and Quality of Oilseed Rape
摘要
Abstract
In response to the issues such as irrational fertilization and unclear dosage of special fertilizers for oilseed rape in Hunan Province,field experiments were carried out with the oilseed rape variety'Xiangzayou 787'and the application of Shaofeng brand oilseed rape-special fertilizer in Hengyang City.The results are summarized as follows.(1)Compared with conventional fertilization,the application of Shaofeng brand oils eed rape-special fertilizer increased the rapeseed yield and plant dry biomass.Moreover,the fertilizer dosage of 450 kg/hm2 achieved the highest yield increase of 16.8%.The yield increase was mainly attributed to the significant increases in branch number and silique number per plant.(2)The nitrogen content in stems and seeds and the potassium content in seeds increased with the increase in fertilizer dosage.The partial factor productivity was high when the special fertilizer dosage was 225 kg/hm2.In conclusion,the application of 450 kg/hm2 Shaofeng brand oilseed rape-special fertilizer can achieve eco-friendly and efficient production of oilseed rape while improving the yield and economic benefits.关键词
