摘要
以蒜青作为试验材料开展氮磷钾"3414"田间试验,结果表明:氮磷钾合理配施可使蒜青获得高产和高效益;蒜青种植过程投入较少、产量和净收入最高的是N2P2K1处理(N、P2O5、K2O每667 m2施用量分别为28.0、14.0、7.5 kg),每667m2蒜青地的N、P2O5、K2O最佳施用量分别为26.40、10.40、7.98 kg(N∶P2O5∶K2O=1∶0.39∶0.30)。
The Garlic Plants "3414" fertilizer experiments were carried out to study influence of N, P and K fertilization on growth and yield in Foshan City in Guangdong Province. The results showed that rational application could not only improve yield but also obtain good effect. In comparison with yield and net income in other treatments, the treatment NEP2KI(N 28 kg/667 m2, P205 14 kg/667 m2, K2O 7.5 kg/667m2) received the highest yield. Taking the economy, yield and fertilization utilization into consideration, the optimum combination was N 26.4 kg/667m2, P2O5 10.4 kg/667m2, K2O 7.98 kg/667m2 and the proportion of N: P2O5:K2O was 1: 0.39: 0.30.
