在陇东黄土高原区进行了紫苏“3414”肥效试验,结果表明,该地区土壤中有效养分含量表现为高K、中P、中N,N是限制产量的主要因子,N、P、K三要素对产量的效应由大到小为N、P、K。紫苏最大施肥量为N 249.45 kg/hm2、P2O5131.10 kg/hm2、K2O 39.30 kg/hm2, N、P、K比例为1:0.52:0.15,该水平下紫苏产量为1892.55 kg/hm2;最佳施肥量为 N 193.05 kg/hm2、P2O5117.90 kg/hm2、K2O 30.00 kg/hm2, N、P、K 比例为1:0.61:0.15,该水平下紫苏产量为1759.65 kg/hm2。
Study on“3414”Fertilizer Efficiency Experiment of Perilla in Loess Plateau of Eastern Gansu
The“3414”fertilizer efficiency experiment of perilla was conducted in loess plateau of eastern Gansu province . The results showed that the soil in this area has abundant available K,medium available P and available N;N is the main factors that limit perilla yields,the effect of increase production is N、P、K . Maximum rate of fertilization is N 249.45 kg/hm2,P2O5 131.10 kg/hm2,K2O 39.30 kg/hm2,the ratio of N:P:K is 1:0.52:0.15,the yield of perilla is 1 892.55 kg/hm2,optimum fertilization is N 193.05 kg/hm2,P2O5 117.90 kg/hm2,K2O 30.00 kg/hm2,the ratio of N:P:K is 1:0.61:0.15 in this level,in this condition perilla yield is 1 759.65 kg/hm2.
