Abstract

The present invention relates to a quantitative self-starting and self-closing type water fertilizer slow-permeation water bag, which comprises a water storage bag, wherein the bottom portion of the water storage bag is provided with at least a slow permeation hole, the top portion of the water storage bag is provided with an automatic starting-closing valve, the automatic starting-closing valve is communicated to a water source through a water inlet pipe, and is communicated to the top portion of the water storage bag through a water outlet pipe, the bottom middle portion in the water storage bag is provided with a magnet, the automatic starting-closing valve comprises a closed soft pipe respectively communicated to the water outlet pipe and the water inlet pipe, an airbag for clogging the outlet of the water inlet pipe is arranged in the soft pipe, the bottom portion of the airbag is fixedly connected to the inner bottom of the soft pipe, the bottom portion of the airbag is provided with a gas outlet hole communicated outside the soft pipe, the outer bottom portion of the soft pipe is provided with a hinge, and the upper valve of the hinge is fixedly arranged on the bottom portion of the soft pipe. The quantitative self-starting and self-closing type water fertilizer slow-permeation water bag of the present invention has characteristics of simple structure, convenient use, and long service life.

Description

technical field [0001] The invention relates to a quantitative self-opening and self-closing water fertilizer slow seepage water bag. Background technique [0002] Water-storage fertilizer irrigation technology is a water-saving fertilization irrigation technology proposed according to the planting structure of fruit tree horticultural economic crops, the characteristics of water and fertilizer requirements and the actual requirements of water-saving irrigation. Through the irrigation water and fertilizer unit, the water and fertilizer required by the crops are quantitatively transported to the fixed water storage and fertilizer slow seepage bag irrigation facility at one time, and the water and fertilizer supply system completes the task of supplying and delivering water and fertilizer in a very short time. Crop irrigation water is a self-releasing process. The time-consuming irrigation and operations are automatically and relatively independently completed in the field, th...
