Abstract

The invention relates to a solid fertilizer precision variable rate fertilizer preparation device for integration of water and fertilizer. The device comprises a precision fertilizer ejector mechanism, a stirring and filtering mechanism, a support frame and a control system. The precision fertilizer ejector mechanism comprises three identical fertilizer ejector mechanisms. The stirring and filtering mechanism comprises two composition structures which are respectively applicable to soluble fertilizers and fertilizers with slow dissolution rate. The support frame is positioned above a mother liquor tank or a mixing tank and used for fixing the precision fertilizer ejector mechanism. The control system comprises a power supply, a WIFI module, user terminal equipment, a precision fertilizer preparation controller, an input / output interface, an EC sensor, a PH sensor and a flow sensor. Ready-to-ejection and ready-to-preparation of mother liquor for fertilizer preparation can be realized, continuity of fertilizer preparation is enhanced. The device has a function of realizing variable rate fertilizer preparation.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to an online fertilization device and a control method for various solid fertilizers suitable for integrated water and fertilizer operations, and is especially suitable for the deployment and use of fertilizer liquid when crops are subjected to integrated water and fertilizer micro-spray irrigation. Background technique [0002] With the development of agricultural science and technology, the increase of crop production is still achieved by applying fertilizers. The integration of water and fertilizer has become an inevitable trend in the development of modern agriculture. key factor. In the existing process of water-fertilizer integration, a variety of water-soluble mother liquors are generally used to mix in proportion. However, due to the high price of water-soluble fertilizers, ordinary farmers cannot bear it, which greatly hinders the promotion process and speed of...
