What Is Drip Irrigation Technology?

Agricultural drip irrigation technology and garden drip irrigation technology are one of the more common irrigation methods in the irrigation industry. Everyone may think that the biggest advantage of drip irrigation technology is water saving. It must be known that the biggest advantage of drip irrigation technology should be the maximum absorption of plant water.

Why can drip irrigation technology achieve this effect? We have to start with a basic concept of "wet ball".

When we irrigate with a drip irrigation system, water drips slowly and evenly into the soil from the dripper. The water under the dripper slowly forms a wet spherical area below the ground surface. This is called a wet ball. Water in different soil textures moves differently, resulting in moist areas of different shapes and sizes. If the soil is weak, such as sandy soil, the wet ball is longer in the vertical direction, and the wet lateral width is about 30-40 cm; if the soil is strong, the soil wet ball is longer than the horizontal direction, and the width is about 60-70 cm; The loam moist sphere is approximately circular, with a width of 50-60 cm.

Then when we design the drip irrigation system, we need to design the spacing and flow of the dripper to adjust the wetting ball according to the difference of the soil, so as to achieve uniform and uniform soil wetting. At the same time cover the effective root system of the crop, and avoid the effect of water infiltration beyond the root zone. Generally, the recommended spacing range of the dripper is 20-30 cm for sandy soil, 50-60 cm for neutral soil, and 70-100 cm for sticky soil. Of course, it should be adjusted according to the planting density of crops. Dense crops have a short distance between drip tips, such as vegetable crops; fruit trees and other row crops have a large distance between drip tips, such as apples and grapes.

Through the drip irrigation system to truly control the depth and width of the plant's water supply range, the advantages of drip irrigation technology can be brought into play, and true water-saving irrigation.

Difference between dripline with cylindrical dripper and custom drip tape

1. First of all, from the appearance, the drip irrigation belt is flat without water and pressure, and the drip irrigation tube is cylindrical;

2. Secondly, it is distinguished from the form of drip heads. Drip irrigation belts are generally inlaid with flat lower heads, and drip irrigation tubes are inline cylindrical drip heads.

3. Use time. Compared with drip irrigation pipe, the thickness of the drip irrigation pipe is thinner, the use time is shorter, and the use time of the drip irrigation pipe is longer;

4. The amount of water output, the water output of the drip irrigation belt is about 2L / h, and the water output of the drip irrigation pipe is about 3L / h. The water output of the drip irrigation pipe is greater than that of the drip irrigation belt;

5. In terms of investment, the investment in drip irrigation pipes is higher than that in drip irrigation belts.

Common drip irrigation has a labyrinth drip irrigation belt and an inlay patch drip irrigation belt. The dripper and drip irrigation belt are integrated. It is easy to use and low in price. There are many users who choose drip irrigation belt.Drip irrigation pipe is an important irrigator in drip irrigation system. According to the requirements of crop water, the water and the nutrients required by the crop are dripped drop by drop through the low-pressure pipe system and the irrigation device installed on the capillary tube, and drip into the crop uniformly and slowly. In the root zone soil. The most common drip irrigation pipe is a built-in cylindrical drip irrigation pipe. The thickness of the drip irrigation pipe is long, the use time is long, and the corrosion resistance is stronger than the drip irrigation tape, but the cost is higher.

Drip irrigation belts use the advantages of their own pipes to directly irrigate water to the roots of crops through the orifice or dripper of a capillary tube with a diameter of about 10mm. The irrigation effect is uniform and water-saving is efficient. The drip irrigation pipe is a low-pressure pipe system and an irrigation device installed on the capillary tube, which irrigates the water and the nutrients required by the crops into the soil in the root zone of the crops uniformly and slowly.

From the above, we can see the difference between drip irrigation belts and drip irrigation pipes, both of which have their own characteristics and advantages. Therefore, when choosing to install and use drip irrigation equipment, you must choose the appropriate drip irrigation product, taking into account the type of crops and planting conditions. Also take into account the useful life of the drip irrigation products.
