摘要
设置烟后稻"3414"田间试验,结果表明,土壤肥力对水稻产量贡献率为71.0%。每667m2施肥量N12.5 kg、P2O5 4.2 kg和K2O 8 kg,N、P2O5、K2O比例为l∶0.34∶0.64,产量最高、施肥效益最佳。
An efficiency trim of N, P and K fertilizer on rice growth was carried out by ＇ 3414＇ experimental design. The results showed that Fertility of soil on rice yield contribution rate is 71.0%. 12.5 kg fertilizer N, P205 4.2 kg and 8 kg K20 per 667m^2, and N, P205, K20 ratio of 1 ： 0.34 ： 0.64, which was the highest yield and fertilizer efficiency best.
