前言肥料(尤其是化学肥料)的经济合理施用是实现甘蔗高产高糖和高效益的一种重要手段。正如 W.Flais 的见解,在作物增产的诸因素中无机肥料的贡献率为50%,育种为20～30%,培肥土壤为15～20%,病虫害防治为10～20%。因此,讲究科学用肥原则,着重提高肥料的利用率,适量而又高效地使用肥料,对甘蔗高产稳产、节肥增收和培肥地力方面具有
Preface The economic and rational application of fertilizers (especially chemical fertilizers) is an important means to realize the high yield, high sugar content and high benefit of sugar cane. As W.Flais’s opinion, the contribution of inorganic fertilizers to crop yield increase is 50%, breeding is 20-30%, fertilizing soil is 15-20%, pest control is 10-20%. Therefore, pay attention to the principle of scientific use of fertilizers, focusing on improving the utilization of fertilizers, appropriate and efficient use of fertilizers, high yield and stability of sugarcane, fertilizer and fertility and fertility have
