Alfalfa water and fertilizer integrated irrigation device

Abstract

The invention discloses an integrated water and fertilizer irrigation device for alfalfa, which comprises: a fermentation tank; a filter tank, the top of which communicates with the discharge pipe of the fermentation tank, the bottom of which is provided with a liquid discharge pipe, and the inside of the filter tank is horizontally provided with a filter screen and a filter screen A slideway is set above the filter tank, and a separation component is provided in the filter tank, and the separation component includes a support column, a first motor, and a filter cartridge; the top of the mixing tank is provided with a liquid inlet and a water inlet, and the liquid inlet is connected to the liquid outlet pipe. The side wall of the mixing tank is provided with a mixed liquid outlet; the drip irrigation mechanism includes a main pipe and a plurality of sub-pipes, the main pipe is connected with the mixed liquid outlet, and a plurality of sub-pipes are connected in parallel and communicated with the main pipe. drip holes. During the growth process of alfalfa, the device of the present invention can add different farmyard manure raw materials for fermentation according to the different nutritional components required for growth, and the fermented material can be treated with a filter tank to obtain a farmyard manure liquid, which is then mixed with water. Complete the integrated irrigation of water and fertilizer.

Description

technical field [0001] The invention relates to the field of irrigation, in particular to an integrated water and fertilizer irrigation device for alfalfa. Background technique [0002] Alfalfa is a perennial pasture, which needs to be mowed 2-4 times a year. Multiple mowings will inevitably take away a large amount of nutrients in the soil. The higher the grass yield, the more nutrients will be taken away, resulting in continuous loss of soil nutrients and scarcity. The prior art satisfies the normal growth of alfalfa by applying liquid fertilizer or solid fertilizer. The traditional soil fertilization method is to mix solid fertilizer into the soil before alfalfa is planted, but for perennial alfalfa, after cutting once, the solid fertilizer applied again can only stay on the soil surface, the fertilization accuracy is low, and the fertilizer utilization rate is low . Farmyard manure is a kind of solid fertilizer, which refers to various organic fertilizers collected, a...

AI Technical Summary

Problems solved by technology

Although the application of liquid fertilizers can increase the nutrients of the soil to a certain extent and provide nutrients for the growth of alfalfa, most of the liquid fertilizers are artificially synthesized chemical fertilizers, which are expensive, poor in popularity, and strictly controlled in dosage. Long-term application is likely to cause soil compaction , affecting the subsequent growth of alfalfa

In addition, the traditional fertilization method needs to be coordinated with watering and irrigation to meet the growth of alfalfa, which increases the complexity of the alfalfa planting process and is time-consuming and laborious
