涪陵区茎瘤芥“3414”肥效试验研究初报

Preliminary Study on the "3414" Fertilizer Experiment of Tumorous Stem Mustard in Fuling District

在涪陵区百胜镇紫竹村的豆瓣泥田中进行茎瘤芥"3414"肥效试验,结果表明,施N13kg/667m2、P2O55.25kg/667m2、K2O6.25kg/667m2的情况下,可获得较为理想的瘤茎产量2843kg/667m2。在此基础上加大肥料施用量的增产效果降低。可见,在该地区实际生产中采取合理的氮磷钾比例配方施肥能够有效地提高茎瘤芥产量,降低生产成本,增加经济效益。

Through the ＂3414＂fertilizer experiment of tumorous stem mustard which carried on bean petal soil in Zizhu village of BaiSheng town, the result indicated that when we fertilized N 13 kg/667m2, P2O5 5.25 kg/667m2, K2O 6.25 kg/667m2, we may obtain more ideal yield 2843 kg/667m2, but the increased effect of tumorous stem mustard yield was dropped when added the fertilizer. Obviously, taking the reasonable proportion of the nitrogen, phosphorus and potassium to fertilize in this local actual production, to increase the tumorous stem mustard yield effectively, reduce the production cost and increase the economic efficiency would.
