Problems solved by technology
This will not only cause unnecessary waste of fertilizer, but also the amount of fertilizer applied is related to the forward speed. If the forward speed is not well controlled, it will easily cause uneven fertilization; Work in the test area
However, digging pits and fertilizing manually will not only easily increase the work intensity of laborers, but also make it difficult to ensure the accuracy of fertilization.
If the amount of fertilizer is large, it is easy to cause seedling burning; if the amount of fertilizer is small, it is easy to cause malnutrition of crops, affect its production, and even cause production reduction

Embodiment Construction
[0031] Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which various embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0032] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
[0033] Before carrying out the fertilization operation, a certain amount of chemical fertilizer is poured from the feed port 5, and then the poured chemical fertilizer slides into the top of the feeding tray 15 along the feeding baffle plate 17 and the holes of the feeding tray 15 fill up. The feed baffle 17 forms a closed space with the material storage box inner wall 16 a...

The invention discloses an accurate fertilizer placement drill for corns, and the accurate fertilizer placement drill can simultaneously realize the integrated operation of hole digging and fertilization in such a way that an operator grips a handle and downwards presses, increase the operating efficiency and the quality and reduce the labor intensity. The device disclosed by the invention is provided with a fertilization adjustable device, thereby being conveniently controlling the fertilization amount. The accurate fertilizer placement drill disclosed by the invention can be used for controlling the fertilizer application amount by changing the volume of the slot of a material dropping disc and achieves the purpose of preventing blocking by digging a hole by utilizing the structure of the cone-shaped body of a cone-shaped anti-blocking open-hole shovel and an internal soil retaining plate.
Description
technical field [0001] The present invention relates to a fertilization device, in particular to an adjustable automatic corn precision topdressing device, which can realize drilling and fertilization operations at the same time, and carry out a corresponding amount of precise fertilization according to different agronomic techniques, and is especially suitable for precision fertilization of crops in test plots. Fertilize. Background technique [0002] At present, the fertilizer applicators on the market generally use ditch openers to open the ditch according to the characteristics of field sowing, and then sprinkle the fertilizer along the way. This will not only cause unnecessary waste of fertilizer, but also the amount of fertilizer applied is related to the forward speed. If the forward speed is not well controlled, it will easily cause uneven fertilization; Work in the test area. However, digging pits and fertilizing manually will not only easily cause the increase of...
