A solid fertilizer precision variable fertilization device and control method applicable to water and fertilizer integration

Abstract

The invention relates to a fine-quantity fertilizer distribution device for solid fertilizer applicable to the integration of water and fertilizer, comprising a precise fertilizer discharge mechanism, a stirring and filtering mechanism, a support frame and a control system; the precise fertilizer discharge mechanism includes three identical fertilizer discharge mechanisms; The stirring and filtering mechanism described above includes two types of structures, which are respectively suitable for easily soluble fertilizers and fertilizers with a slow dissolution rate; the support frame is located above the mother liquid tank or mixing tank to fix the precise fertilizer discharge mechanism; the control system includes power supply, WIFI modules, user terminal equipment, precision fertilizer distribution controllers, input and output interfaces, EC sensors, PH sensors and flow sensors; the invention can realize the distribution of fertilizer mother liquid according to the row, improves the continuity of fertilizer distribution, and has the ability to realize variable distribution Fat function.

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...
