摘要
运用小区试验与大田示范相结合的方法,以阜花30号花生品种为试验对象,研究风沙区土壤氮、钾不同水平配施在不同时期追肥对花生氮含量、产量品质以及收获后土壤养分的影响,以探究辽宁省肥料高效的施肥水平。结果表明,当施氮水平达到147.45 kg/hm^2时效果最佳,再增加氮水平不但不会增产反而会减产,浪费氮肥;同等施肥量(过磷酸钙344.25 kg/hm^2、尿素147.45 kg/hm^2、硫酸钾335.25 kg/hm^2)情况下,以磷为底肥追施氮钾肥的处理优于以磷钾肥为底肥追施氮肥的处理,其花生产量较高、品质较好。不同施肥水平均能提高花生根、茎、叶的氮含量以及花生产量和品质,以施尿素59.2 kg/hm^2、硫酸钾134.4 kg/hm^2、过磷酸钙335.25 kg/hm^2为底肥,在幼苗期追施尿素6.4 kg/hm^2、硫酸钾24.3 kg/hm^2,在开花期追施尿素52 kg/hm^2、硫酸钾151.4 kg/hm^2,在结荚期追施尿素20.8 kg/hm^2、硫酸钾24.3 kg/hm^2,在饱果期追施尿素9.6 kg/hm^2、硫酸钾1.6 kg/hm^2的T8处理施肥效果最佳。
Based on the soil conditions in sandy areas,this paper studied the effect of different levels of nitrogen and potassium combined fertilizer application at different stages on the nitrogen content,yield and quality of peanut and soil nutrients after harvest to explore a more economical and effective fertilizer proportion and find out the high efficient fertilizer application level in Liaoning province.With the method of combining plot test and field demonstration,the peanut variety Fuhua 30 was taken as the test object.The results showed that when the nitrogen application level reached 147.45 kg/hm^2,the yield was higher and the quality was better.At the same fertilization rate(344.25 kg/hm^2 of superphosphate,147.45 kg/hm^2 of urea and 335.25 kg/hm^2 of potassium sulfate),the treatment of topdressing nitrogen and potassium fertilizer with phosphorus as the base fertilizer was better than that of topdressing nitrogen fertilizer with phosphorus and potassium as the base fertilizer,its yield was higher,the quality was better.The nitrogen content of root,stem and leaf,yield and quality of peanut could be increased at different fertilization levels,and T8 treatment was the best.
