茭白配方专用肥肥效比较试验

通过与常规施肥比较,研究茭白配方专用肥对茭白生物学性状、产量和品质的影响。试验结果表明:茭白商品性有明显改善,粗脂肪、维生素C、总糖、氨基酸等品质指标增幅达到极显著水平,并可实现增产增效21.96%,节约肥料成本6.53%,利润提高25.98%。在配方专用肥的基础上增施氮肥,不能提高茭白产量,且肥料成本增加,种植效益明显下降。

Fertilizer comparison test of the special formula fertilizer for Zizania latifoia

In this study, by comparing the conventional fertilization with the special formula fertilizer for Zizania latifolia, the effect of the special formula fertilizer on biological characters, yield and quality were studied. The results show that there is a significant improvement in Zizania latifolia commodity traits, and the crude fat, vitamin C, total sugars, amino acids, and other quality indicators are increased significantly. Appling special formula fertilizer results in 21.96% increase in yield and efficiency, a 6.53% reduction in fertilizer costs, a 25.98% increase in profit. In addition, adding nitrogen fertilizer on the basis of the formula specialty fertilizer can’t improve Zizania latifolia’s production, and planting efficiency decreases with the increase of fertilizer costs.
