Water-fertilizer integrated device for greenhouse

Abstract

The invention relates to the field of agricultural water conservancy engineering, and provides a water-fertilizer integrated device for a greenhouse. The water-fertilizer integrated device comprises a greenhouse, and also comprises a water storage unit, a fertilizer dissolving unit, a controller and a plurality of spray-irrigation units, wherein the spray-irrigation units are arranged in soil located at the periphery of the root part of a crop in the greenhouse; the water storage unit and the fertilizer dissolving unit are in connection through a water delivery pipeline; the lower end of the fertilizer dissolving unit is provided with a main pipeline extending into the greenhouse; each spray-irrigation unit is connected with the main pipeline through a branch pipeline; and the water storage unit is connected with the main pipeline through an irrigation water pipe. The water-fertilizer integrated device for the greenhouse provided by the invention can realize automatic, highly-precise and direct applying of a fertilizer and water to the root part of a plant, achieves the purposes of saving water, reducing the fertilizer and increasing yield, reduces the labor intensity of workers, improves production efficiency, and reduces cost.

Description

Technical field [0001] The invention relates to the field of agricultural water conservancy engineering, in particular to a water and fertilizer integrated device for a greenhouse. Background technique [0002] Greenhouses, also known as greenhouses and greenhouses. A facility that can transmit light, keep heat (or heat), and cultivate plants. In the seasons that are not suitable for plant growth, it can provide greenhouse growth period and increase yield. It is mostly used for plant cultivation or seedling cultivation of temperature-loving vegetables, flowers, forests and so on in low temperature season. The cultivation of the existing greenhouse crops basically relies on manual operation. The field management during the growth period of the crops and the later sales of vegetables require direct manual participation. For example, the irrigation and fertilization during the growth of agricultural and horticultural plants are judged and implemented manually, but the basic fertili...

Problems solved by technology

Or to supplement the deficiency of base fertilizer, but during the process of topdressing, it is easy to trample and break the vegetables, and it is also easy to cause side effects on the root system of the crops, that is, root burning, and it is difficult to fertilize a large area, and the labor intensity is high, so the same fertilization often occurs. Inconsistencies in time, unevenness, etc.

Moreover, a large amount of water will be wasted in the irrigation project, the workload of the workers is heavy, and the efficiency is low, and the fertilization and irrigation system of the prior art is manually controlled, the operation is complicated, the irrigation and fertilization are controlled separately, the system stability is poor, and the protection of the motor is not considered. and protection of the entire pipeline
