摘要
针对玉米种植过程中因化肥的不当使用造成的资源浪费和环境污染问题,结合中耕施肥技术,研制了一种可一次性完成除草、松土、变量追肥和培土起垄3ZBF-7型中耕机,并在示范区进行了试验。通过对其追肥用量、玉米产量等进行综合分析,得出使用中耕变量追肥机能够实现节肥的功效,并在一定程度上提高了经济效益和生态效益。
Combining the technology of intertillage, this paper introduces the 3ZBF-7 type of cultivator to settle the re-source waste phenomenon and environmental pollution problems caused by improper use of fertilizers during the process of maize production.The operation of weeding, scarification, variable fertilizer and ridging can be done one-time by the machine.The experiment has been conducted in demonstration areas and the amount of topdressing, the final production and the amount of increase revenue and reduce expenditure has been statistical analyzed.It is concluded that row variable fertilizer machine can achieve the effect of saving fertilizer and improve the economic benefit and ecological benefit To a certain extent.
