摘要
针对目前由于施肥方法不当、施肥量难以精确控制、利用率低、容易造成施肥过量、肥效持续时间短、易挥发和环境污染等问题,设计了一种小型施肥器。其结构简单、操作方便且成本低廉,能在土壤中形成孔穴,将肥料直接输送到作物根部,实现精确定量和定深的施肥目标。该施肥器不仅有效提高肥料的利用率,而且减少污染、保护环境。
A mini-type of fertilizing equipment was designed aiming at the situation of incorrect fertilizing and difficult to control the amount of fertilization and low utilization ratio which will lead to the problems of short-time fertilizer effect,easy volatilization and environmental pollution.It＇s simple in structure,convenient to handle and inexpensive to manufacture.When completing fertilization,it realizes the aim of quantify and depth in accurate,and can make a hole in soil to send the fertilizer to the roots of the plants.It will raise utilization ratio as well as reduce the pollution.
