- 摘要:
- 采用不完全正交设计方法, 研究了庆安县水稻主产区黑土和草甸黑土水稻高产优质适宜的氮磷钾用量。试验结果表明, 在中低产条件下, 庆安县水稻氮磷钾适宜用量为:N 100 ~ 150 kg · hm -2 、 P2O5 60~ 90 kg · hm -2 、K2O 75 ~ 125 kg · hm -2 , 氮磷钾适宜比例为1.7 ∶1 ∶1.3。在高产条件下, 水稻氮磷钾适宜用量为:N100 ~ 200 kg · hm -2 、P2O5 60 ~ 90 kg · hm -2 、K2O 75 ~ 125 kg · hm -2 , 氮磷钾适宜比例为2.5 ∶1 ∶1.3。从产量和品质两个方面综合考虑, 庆安县水稻施肥氮、磷、钾的适宜用量为N 100~ 150 kg · hm -2 , P2O5 60 ~ 90 kg · hm -2 , K2O 75 ~ 125 kg · hm -2 为宜, 过高或过低对产量和品质均有显著的负效应。
