技术领域technical field
本发明属于农业机械技术领域，特别涉及一种用于穴播作物精准施肥的气吹式穴施肥装置。The invention belongs to the technical field of agricultural machinery, and in particular relates to an air-blown hole fertilization device for precise fertilization of hole-sown crops.
背景技术Background technique
种肥是在播种环节和种子一起施入土壤的肥料，对作物的生长具有重要意义，现有穴播作物施肥方式多为条施。肥料条施施肥量和施肥位置不稳定，容易造成烧种(苗)现象，且因化肥分散分布、没有针对特定种子而造成化肥浪费。肥料穴施技术可以定点定量精确施肥，单穴肥料供应单穴作物，施肥分布在利于作物根系吸收的范围内，相关试验表明具有很好的节肥增产效果，是提高穴播作物肥料利用效率的有效手段。因此，机械化穴施肥技术是目前精准施肥领域研究的主要方向之一。Seed fertilizer is the fertilizer that is applied to the soil together with the seeds during the sowing process. It is of great significance to the growth of crops. The existing method of fertilization for hole-sown crops is mostly bar application. The amount of fertilizer applied and the position of fertilization are unstable, which may easily cause the phenomenon of burning seeds (seedlings), and the scattered distribution of chemical fertilizers and the lack of specific seeds will cause waste of chemical fertilizers. Fertilizer hole application technology can be used for quantitative and precise fertilization at fixed points. Single-hole fertilizer is supplied to single-hole crops. Fertilization is distributed within the range that is conducive to the absorption of crop roots. Relevant tests have shown that it has a good effect of saving fertilizer and increasing production. means. Therefore, mechanized hole fertilization technology is one of the main research directions in the field of precision fertilization.
目前已有的穴施肥装置如专利(申请)号：CN201611199767.7一种玉米正位穴深施肥精播机及其精播方法，通过间歇排肥机构将排肥器排出的肥料间歇排入土壤；专利(申请)号：CN02259249.0播种机用穴施肥器，通过弹射连杆打开或关闭活门，实现间歇送肥。但现有机构均通过纯机械方式实现，排肥精度差，效率低，不能满足高速、高效机械化播种施肥需求。因此，研制一种可实现快速、精准的穴施肥装置具有重要的意义。At present, existing hole fertilization devices such as patent (application) number: CN201611199767.7 a kind of correct seeding machine and precision seeding method for deep fertilization of corn positive hole, the fertilizer discharged by the fertilizer device is intermittently discharged into the soil through the intermittent fertilizer discharge mechanism ; Patent (application) No.: CN02259249.0 hole fertilizer applicator for planter, open or close the valve through the ejection connecting rod to realize intermittent fertilizer delivery. However, the existing mechanisms are all realized by purely mechanical means, with poor precision and low efficiency of fertilizer discharge, which cannot meet the needs of high-speed and high-efficiency mechanized sowing and fertilization. Therefore, it is of great significance to develop a fast and accurate hole fertilization device.
