摘要
通过水稻施肥"3414"小区试验,经方差、多重比较,氮磷钾不同处理间产量存在一定的差异显著性,回归分析表明,在绥阳县水稻每667m2最佳施肥量为:氮(N)11.60kg、磷(P2O5)6.75kg、钾(K2O)7.49kg,水稻可获得最佳经济产量为:827.13kg/667m2。
3414 fertilization on rice was tested. from analysis of variance and multiple LSD comparison. the difference of yield of rice under NPK fertilization was significantly. the results showed that the best fertilizing amount was N 11. 60kg/667m2, P2O5 6. 75kg/667m2, K2O 7. 49kg/667m2, respectively. which can obtain the best economical yield 827. 13kg/667m2.
