Embodiment
[0026] Such as Figure 1-4 A layered fertilizer applicator for soil improvement in saline-alkali land is shown, comprising a support frame 1, a fertilizer box 2 is fixed on the top of the support frame 1, and a front fertilization mechanism 3, a rear Fertilization mechanism 4, the length of the toggle blade 12 in the front fertilization mechanism 3 is less than the length of the toggle blade 12 in the back fertilization mechanism 4, during work, it can be turned over to the soil of different depths, and for the soil after turning Fertilization provides conditions, and through the expansion and contraction of the cylinder 25, the height between the whole body of the fertilization mechanism 4 and the surface to be contacted is adjusted, so that the fertilization device can fertilize according to the degree of salinization between different layers of soil, thereby greatly improving Soil absorption rate and resource utilization rate, avoiding too much or too little fertilizer appl...

The present invention disclosed a layered fertilizer for saline -alkali land soil, which belongs to the field of saline -alkali soil fertilization equipment, including the support frame. The top of the support frame is fixed with a fertilizer box.The support wheel, the previous fertilization mechanism includes the discharge module and the cutting module, which includes the fertilization mechanism, including the module, the adjustment module and the cutting module.The present invention can turn the length of the blade through the internal fertilization mechanism, so that it can rectify the soil of different depths, providing conditions for fertilization work after rectification, and through the expansion of the cylinder, the fertilization mechanism after adjustment is to be contacted with the need to contact the contact surface as a wholeThe height between the fertilizer can be used for targeted fertilization according to the degree of salinization inside the soil, which greatly improves the utilization rate of fertilizer, and avoids excessive or too little fertilization.The improvement effect causes adverse effects.
Description
technical field [0001] The invention relates to the field of fertilization equipment for saline-alkali soil, in particular to a layered fertilizer applicator for saline-alkali soil improvement. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water, and after the water evaporates, the salt accumulates in the surface soil; it refers to the phenomenon or process in which soluble salt accumulates in the soil surface. The saline-alkali soil in my country has a large area and a wide distribution. It is generally distributed in plains or basins with flat terrain and deep soil layers, and has not been well developed and utilized due to the harm of salinization. However, with the impact on land productivity and resources With the improvement of demand, people's awareness of soil saline-alkali land management is constantly improving, and the design of fertilization devices for ...
