以"沈农燕麦一号"为试材,采用二次四因子二次通用旋转组合设计,研究辽宁省适宜燕麦生长的播种密度和肥料施用量。结果表明:在产量≥3000kg/hm2的147个方案中,播种量在174.00~185.25kg/hm2,N、P2O5、K2O施用量分别为135.75~152.25kg/hm2、37.35~41.10kg/hm2、110.40~121.05kg/hm2,可获得3581.25kg/hm2以上的产量,N∶P2O5∶K2O最适比例为3.67∶1.00∶2.95。
In order to study the appropriate seeding rate and fertilizer,"shennong NO.1" oat was used in the second four-factor quadratic general rotation design.Results showed that in the 147 programs which yield are ≥3 000 kg /hm2,it can get a per hectare yield more than 3 581.25 kg /hm2 when the seeding rate is at 174.00~185.25 kg /hm2,N,P2O5,K2O fertilizer are at 135.75~152.25,37.35~41.10,and 110.40~121.05 kg /hm2 respectively.The best appropriate of N:P2O5:K2O is 3.67:1.00:2.95.
