施用有机液体肥料对大白菜养分吸收和产量的影响

Effects of organic fluid fertilizer applied on nutrient absorption and yield of Chinese cabbage

研究不同液体肥料(20-7-18)对大白菜产量和品质的影响,结果表明:以味精废液为基础调节pH发酵配制的有机液体肥料的使用效果最好,氮磷钾养分吸收量比无机液体肥料处理和固体混合肥处理N分别提高33.1%和16.2%,P2O5分别提高31.5%和11.1%,K2O分别提高22.7%和10.2%,大白菜产量分别提高6.8%和21.9%。

The field experiment of different organic fluid fertilizers （20-7-18） applied on Chinese cabbage was conducted to study the nutrient absorption and yield. The results showed that the application of organic fluid fertilizers, which was formulated by regulating pH and fermenting on the basis of the waste water of monosodium glutamate, was most effective. Compared with the treatments of equivalent solid mixed fertilizer and inorganic liquid fertihzer applied, the absorption amount of N,P205 and K20 were enhanced by 33.1% and 16.2%, 31.5% and 11.1%, 22.7% and 10.2%, respectively, and the yield of the cabbage product were increased by 6.8% and 21.9%.
