A fertilization device for agricultural stratified variable fertilization

Abstract

The invention discloses an agricultural fertilization device for layered variable fertilization, which comprises a mounting frame, a fertilizer box is installed in the middle of the top of the mounting frame, a mixing box is installed at the bottom of the fertilizer box, and the inner bottom of the mixing box is A material mixing partition is provided, and fertilization notches are opened through both sides of the material mixing partition. The invention can achieve the purpose of separating and mixing the fertilizer through the fertilizer partition and the mixing partition, and ditching with the ditching shovel, discharging part of the mixed fertilizer into the bottom of the ditch, and pushing part of the soil back to the ditch through the soil cover plate. After putting in another part of the fertilizer, and then effectively realize the layered variable fertilization of fertilizers with different mixing ratios, making the fertilizer in the soil easier to be absorbed by the crop roots, solving the problem that the existing variable fertilization is mostly single-layer fertilization, which cannot be carried out at different depths The problem of applying different amounts of fertilizer to the soil.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural fertilization device for layered variable fertilization. Background technique [0002] Variable fertilization, also known as precision fertilization, is based on the investigation of soil nutrient elements at different locations. The variable fertilization controller placed on the tractor controls the motor speed at the end of the power shaft of the fertilization box to adjust the amount of fertilizer discharge to achieve the purpose of discharging different amounts of fertilizer. , so that the crops have enough nutrients during the growth process and grow normally, but there will be no waste of fertilizer due to excessive fertilization. However, the current variable fertilization device can only do single-layer fertilization, and cannot apply different soils at different depths. The amount of fertilizer caused by the fertilizer can not be more effe...
