Description

Gravity fertilizer irrigation system

The invention relates to a fertilizer irrigation system, in particular to a gravity fertilizer irrigation system suitable for fertilizing irrigation of a plurality of crops by liquid.

In addition to timely watering and irrigation, the regular application of fertilizers is also an indispensable task. Because Taiwan is located in the subtropical region, crop pests and diseases are paralyzed. In order to make the crops grow smoothly, the farmers usually apply fertilizers before planting and even during cultivation to supplement the nutrients needed for crop growth and promote the breeding of beneficial microorganisms. Spray pesticides or herbicides in the process to prevent crops from being attacked by pests and weeds.

The irrigation methods of existing crops can be divided into flood irrigation, furrow irrigation, sprinkler irrigation, micro-sprinkler irrigation, underground irrigation, and drip irrigation. Among them, the practice of flood irrigation and furrow irrigation is similar to direct water injection into the farmland through the Shenzhen Road or the water pipe, so that the water is spread to all parts of the farmland. The water of these irrigation methods is most severely evaporated, leaked and lost. Therefore, the least efficient and most wasteful water source.

At present, the more commonly used irrigation methods include micro-sprinkler irrigation and drip irrigation. The drip irrigation mainly drops the water source directly near the root of the crop, so the water consumption is relatively low. The micro-sprinkler irrigation mainly consists of a large amount of water covering a wide area, so the crops will not be short of water.

Referring to Figure 1, the "Irrigation Device" of the Republic of China No. M457402 is a micro-sprinkler irrigation method. The irrigation device comprises a water conduit 11, a pump 12, a spray device 13, and a certain time device. 14.
