摘要
文章在水稻机穴播同步侧深施肥技术上开展化肥减量施用探索,以常规撒施基肥为对照,设置3个不同梯度侧深施用基肥进行对比试验,考察侧深施肥技术对工作效率、生产成本等的影响,通过苗情考察、产量测定等数据寻求最佳的施肥量,为全区范围内进一步示范推广提供技术支撑和参考依据。试验表明,应用机穴播侧深施肥技术,有利于肥料的吸收,可减少肥料流失,提高肥料利用率,同时减少了一次撒施基肥的用工。
In this paper, the application of chemical fertilizer reduction was explored on the technique of synchronous side deep fertilization of rice machine hill-drop sowing. Taking the conventional base fertilizer as the control, three different gradient side deep fertilization base fertilizers are set for comparative experiments to investigate the impact of side deep fertilization technology on work efficiency and production cost, and seek the best fertilization amount through seedling investigation, yield measurement and other data, provide technical support and reference basis for further demonstration and promotion in the whole region. The test shows that the application of machine hole sowing side deep fertilization technology is conducive to the absorption of fertilizer, reduce the loss of fertilizer, improve the utilization rate of fertilizer, and reduce the labor of one-time application of base fertilizer.
