Hole fertilization type quantitative fertilization device

Abstract

The invention relates to the technical field of fertilization equipment, and discloses a hole fertilization type quantitative fertilization device. The hole fertilization type quantitative fertilization device comprises a tumbril, wherein a control sliding groove with a downward opening is formed in the tumbril, a control sliding block is arranged in the control sliding groove in an up-down sliding mode, and an electric telescopic rod fixedly arranged on the top wall of the control sliding groove is fixedly arranged at the upper end of the control sliding block. When the hole fertilization type quantitative fertilization device is used for fertilizing, fertilizer is quantified, holes are drilled in soil through a cambered surface plate, the bottoms of the holes in the soil are opened through the cambered surface plate, then the quantitative fertilizer is fed into the pre-drilled holes, and the quantitative fertilizer is fed into the soil, so that the problem of water loss caused during fertilizing is greatly reduced, and the fertilizing amount can be acutely controlled at the same time; meanwhile, the device can be compatible with solid fertilizer and liquid fertilizer, and the fertilizer can be conveyed into the soil in an accurate and controllable mode, so that the labor intensity during fertilizing is greatly reduced, and the working quality and the working efficiency of fertilization are improved.

Description

technical field [0001] The invention relates to the technical field of fertilization equipment, in particular to a hole-type quantitative fertilization device. Background technique [0002] At present, the fertilization of the land is usually to directly sprinkle the granular fertilizer on the surface of the land. Not only is the fertilizer distributed unevenly, but also the fertilizer dissolves into the water and then penetrates into the soil. The efficiency of fertilization is low. Some farmers will spread the fertilizer on the land. Turn over the soil surface once, the lower soil layer has high humidity, turning over the soil surface will cause the loss of soil moisture, resulting in loose soil on the surface, and it is easy to cause dust problems when the wind blows over. The present invention improves on the above shortcomings. Contents of the invention [0003] The object of the present invention is to provide a hole application type quantitative fertilization device...
