Fixed-point efficient fertilizer burying method good for growth of tea trees

Abstract

The invention provides a fixed-point efficient fertilizer burying method good for growth of tea trees. The method comprises the following steps: firstly, a back box transports fertilizer in the back box towards an upper cylinder continuously and slowly, and the fertilizer falls into an inner cavity through the upper cylinder and a rotating cylinder in a cylinder member; then, a drill barrel and adrill bit abut against the ground near the root of a tea tree vertically downward, and the rotating barrel is driven by external force to rotate around own axis and drives the drill bit and the drillbarrel to rotate synchronously, and the drill bit and drill barrel cooperate to perform fixed-point pit drilling on the ground; next, a trigger mechanism overcomes the effect of elastic force of a return spring and pushes a floating ring to slide down along the drill barrel, the drill bit removes seal on a lower end opening of the rotating cylinder, and the fertilizer in the inner cavity flows outof the lower end opening of the drill barrel and is buried in a pit; and finally, under the elastic force of the return spring, the drill bit automatically resets and restores seal for the lower endopening of the drill barrel, the drill bit and the drill barrel are pulled out, and soil automatically rolls down to backfill and cover the pit.

Description

technical field [0001] The invention relates to the technical field of tea garden fertilization, in particular to a fixed-point and high-efficiency fertilization method that is beneficial to the growth of tea trees. Background technique [0002] After retrieval, the applicant found that there is a kind of tea tree fertilization equipment currently on the market, which mainly digs a deep ditch between the tea tree rows, puts the fertilizer in the deep ditch, and then backfills the soil to the deep ditch and fills it up. To a certain extent, the fertilization efficiency of tea trees has been improved, but there are also obvious disadvantages. It is pointed out one by one. First, the deep ditch excavated is located between the rows of tea trees, so that the fertilizer cannot reach the roots of the tea trees; Large areas are placed in deep trenches, resulting in waste of fertilizers; third, the depth of excavated deep trenches is difficult to control, and it is impossible to acc...
