What is drip irrigation and its advantages and disadvantages?
time: 2020-03-19

Drip irrigation is a precise irrigation method. It uses a low-pressure pipe system to directly deliver water to the field, and then passes the dripper, orifice or drip irrigation belt installed on the capillary to drop the water evenly and slowly Drop into the soil near the crop root zone, so that the soil in the most developed crop root system often maintains suitable humidity, so that the soil's water, fertilizer, gas, heat, and microbial activities are always in good conditions, creating favorable conditions for high and stable crop yields.


Advantages of drip irrigation:

1.Drip irrigation light weight.Easy to arrange and collect in the field.

2.Drip irrigation tip distance can be adjusted according to user needs.

3.Drip irrigation has good mechanical strength. It is convenient for mechanized operation and laying.

4.Drip irrigation is suitable for many situations such as field crops, greenhouse vegetables and fruit tree cultivation.

5.Drip irrigation uses new materials. High strength, corrosion resistance and aging resistance.

6.Drip irrigation can apply both water and fertilizer. Improve fertilizer utilization rate. Provincial labor. Provincial fertilizer.

7.Drip irrigation can save more than 85% of water, save more than 65% of energy, and increase production by more than 30%.


Problems with drip irrigation:

1. Drip irrigation is easy to block (due to the 0.5-1.2mm of the dripper flow channel, plus the blocking of organic matter and processing impurities), the current use of large flow channels is to solve the current blockage problem. The drip irrigation belt is disposable, and the built-in drip irrigation tube is used for 3-4 years. This is the reason.


2. Restricted root system development Because drip irrigation only partially wets the soil, while crop roots are water-oriented and fertile. Because the moist body is 30cm near the ground, it affects the root system's infestation and development. Weak drought resistance. But it can be solved through rational design, proper arrangement of drippers and scientific management.


3. Salt accumulation Under the condition of drip irrigation, soil salt accumulates at the edge of the humid area. When it encounters light rain, these salts harm the crops.
