Facility production field micro-area water and fertilizer integrated device

Abstract

The invention relates to an agricultural scientific test device, in particular to a facility production field micro-area water and fertilizer integrated device. According to the structure of the facility production field micro-area water and fertilizer integrated device, a signal input end of a controller is electrically connected with all liquid level meters and pulse flow meters of a fertilizer and water irrigation system; the signal output end of the controller is electrically connected with a water pump as well as all water inlet electromagnetic valves and fertilizer and water electromagnetic valves of the fertilizer and water irrigation system; a manual control switch and an automatic control switch are arranged on the controller; a water pool and the water pump are connected through a water pipe; a water outlet of the water pump is connected with a water inlet pipe; and the water inlet pipe is connected with water inlet branch pipes of all fertilizer water irrigation systems. Water and fertilizer can be uniformly and quantitatively supplied at regular time by utilizing a controllable pipeline according to the fertilizer requirement rule and characteristics of cultivated crop varieties, so that the randomness of manual operation is avoided, the production efficiency is improved, the labor cost is reduced, and the fertilizer is prevented from volatilizing on the earth surface to be lost.

Description

technical field [0001] The invention relates to an agricultural scientific experiment device, in particular to a facility production field micro-area water and fertilizer integration device. Background technique [0002] The development of modern agricultural production pursues less investment and more harvest. In the production process, water is a necessary condition for crop growth, and fertilizer is an important guarantee for increasing and high yield. The rational use of water and fertilizer is an important factor for the sustainable and healthy development of agriculture. Therefore, directly transporting water and fertilizer to the roots of crops can Greatly reduce input costs. For a long time, fertilization and watering in traditional agricultural production have all been based on feeling. Fertilization mostly uses the methods of spreading, furrowing, and hole application, and then flooding with water. Watering and fertilizing in this way, on the one hand, part of the...

Problems solved by technology

For a long time, fertilization and watering in traditional agricultural production have all been based on feeling. Fertilization mostly uses the methods of spreading, furrowing, and hole application, and then flooding with water. Watering and fertilizing in this way, on the one hand, part of the fertilizer will volatilize on the surface On the other hand, after flood irrigation, the fertilizer will be washed down to 30 cm below the ground surface. This method of fertilization leads to low fertilizer utilization efficiency. The more fertilizer is used, the more fertilizer is used, but the yield does not increase.
