为了提高旱稻的产量、质量,采用正交旋转组合试验设计,研究了氮、磷、钾肥用量配方对巴西陆稻IAPAR9的生长发育产量、品质和效益的影响进行了系统研究.建立了湖南省红黄泥土壤条件下巴西陆稻IAPAR9栽培中施肥量与产量、米质的数学模型,并分别优选出高产量、高利润各10套施肥方案和米质最佳施肥方案.当N,P2O5,K2O分别为295.2,147.6,295.2 kg/hm2 ,三者比例为2∶1∶2,可获得最高产量5 012.64 kg/hm2,最高利润为2 975.76元/hm2,最高整精米率62.56%,较低垩白粒率19.19%和最高蛋白质10.24%.

The anthor aims at the main nutritional characteristics and different effects of various applying ratios of nitrogen (N), phosphate (P) and potassium (K) on yield and quality of Brazilian upland rice IAPAR9, based on the field experiment with the orthogonal rotational combinatorial design. Mathematical models of recommended fertilization of nitrogen,phosphorus and potassium for Brazilian upland rice in Reddish yellow clayey earth were set up by means of orthogonal rotational combinatorial design and computer simulation optimixing.10 fertilizati...
