filling case, the water in the water filling case 201 can be through the tiny water pipe 202 that adds slowly instils into broadcasting case 101 in to continuous losing water to broadcasting in the case 101 and supplementing, and then the infiltration of guaranteeing chemical fertilizer solution can continuation go on, the setting of observation window 203 can be convenient for observe the water level that adds in the water filling case 201.
Referring to fig. 1-5, a method for using a pre-buried fertilizer spreading device with enhanced efficiency and reduced application includes the following steps:
s1, digging a soil pit matched with the sowing device in size in a farmland, putting the sowing device into the soil pit and burying the soil pit, and enabling the pipe cover 109, the handle rod 110 and the observation window 203 to leak out of the soil surface;
s2, when fertilizing, the pipe cover 109 is screwed off through the rotation of the handle rod 110, a proper amount of fertilizer particles mixed with additives are put into the slow release mechanism 003 through the feeding pipe 104, and then clear water is injected into the sowing box 101 and the water adding box 201 through the feeding pipe 104 until the water level in the water adding box 201 is equal to the height of the water injection hole 111;
s3, screwing the pipe cover 109, and waiting for the fertilizer to automatically infiltrate into the soil.
The additive in the step S2 comprises osmotic pressure active substance and pushing agent, the osmotic pressure active substance is sodium chloride, the pushing agent is polyethylene glycol with high molecular weight, fertilizer particles are put into the cylindrical membrane 301 through the feeding pipe 104 by the combined arrangement of the water injection pipe 103, the feeding pipe 104, the cylindrical membrane 301, the slow release hole 303, the water adding pipe 202, the additive and the like, after water is injected into the sowing box 101 through the water injection pipe 103, the water permeates the cylindrical membrane 301 and is mixed with the fertilizer particles to form fertilizer solution, the sodium chloride is used as osmotic pressure active substance, the solution in the cylindrical membrane 301 is high-osmotic, the osmotic pressure existing inside and outside the cylindrical membrane 301 enables the water to continuously enter the cylindrical membrane 301, so that the fertilizer solution is pumped into the sowing box 101 through the slow release hole 303, then is guided to the osmotic hole 107 by the diversion cotton core 106 and is put into the soil for fertilizer sowing, the water adding pipe 202 can continuously supplement the water in the sowing box 101, high molecular weight polyethylene glycol absorbs water and expands, can regard as the boosting agent for the pump of chemical fertilizer solution, the process of scattering of chemical fertilizer is slow and duration is long, when reducing the chemical fertilizer is volatile, make soil and crops can be to the better absorption of chemical fertilizer, and then improved the effect of chemical fertilizer, has reached the purpose that a synergism subtracts the execution, when using, the user can be according to the farmland area, through evenly putting in a plurality of devices of scattering, carry out the scattering of chemical fertilizer to big piece farmland.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
