rice transplanter layered fertilizer applicator

Abstract

The invention discloses a layered fertilizer applicator of a rice transplanter. The layered fertilizer applicator comprises a transmission case connected with two fertilizer application pipes side by side, a fertilizer application screw shaft is arranged in each fertilizer application pipe, the fertilizer application screw shaft is connected with a transmission device in the transmission case, and the fertilizer outlets of the two fertilizer application pipes are arranged in different height positions. The fertilizer applicator can carry out layered fertilizer application, and the fertilizer application mode improves the absorption efficiency of seedlings for fertilizer in the growing process and also is favorable for the roots of the seedlings to grow toward two sides and grasp land firmly.

Description

technical field [0001] The invention belongs to the technical field of rice transplanters, and in particular relates to a fertilizer applicator for rice transplanters. Background technique [0002] At present, it has become a consensus in the industry that the rice transplanter can greatly save the amount of fertilizer used by fertilizing while transplanting rice seedlings. The auger fertilizer applicator has been widely used because of its simplicity and ease of use, and it is not suitable for clogging. However, in use, one auger corresponds to a row of seedlings, and the fertilizer particles are concentrated on a depth on one side of the seedlings. The fertilization of plants makes the roots of the seedlings grow toward the side of the fertilizer, resulting in poor grip, and the seedlings are in the initial stage of growth. More fertility is needed, but because it is far away from the fertilization point, it cannot be effectively absorbed. Although the roots grow downward...

Problems solved by technology

However, in use, one auger corresponds to a row of seedlings, and the fertilizer particles are concentrated on a depth on one side of the seedlings, and the plant's fertilization makes the roots of the seedlings grow toward the side of the fertilizer, causing the ground to be weak, and the seedlings are in the initial stage of growth. More fertility is needed, but because it is far away from the fertilization point, it cannot be effectively absorbed. Although the roots grow downward and gradually approach the fertilization point, due to the long time, the fertilizer efficiency has decreased, resulting in low fertilizer use efficiency.
