Dropping Irrigation

Description of dripping irrigation system

1. Due to the lack of awareness, capital and technology, agriculture production (including the increasingly active horticulture industry) keeps using the traditional and backward immersing irrigation. With the worsening of water resources shortage and increasing demand for water, immersing irrigation is gradually replaced by modern dropping irrigation which can save more water.
2. Dropping irrigation means drop water into the soil near crop root evenly and slowly by drop arrows, drippers, drip tapes or other orifice -type emitters on capillary tube. This way can reduce evaporation and save water.
3 . The modern science irrigation technology can take advantage of water resources effectively; relieve excessive groundwater extraction and crustal subsidence. Besides that, with the combination of exact fertilizer, this action can improve the growth conditions of crops, fruits and flowers. From this, the unit yields will be improved and excellent social and economical benefits will be improved.
4. Local precision irrigation can improve the maximum utilization of water, reduce grass, control soil humidity, reduce damaged insects and improve soil conditions.

Classifications of equipment for dripping irrigation system

1. Dripper
2. Connector
3. for Micro Irrigation And Drop Irrigation Only
4. Hole puncher
5. Fertilization System

Applications of dripping irrigation system

It is widely used for fruit trees, cotton, flowers, vegetables, melons, herbs, greenhouses, agricultural fields, crops, sand forestation and urban landscaping.

Features of dripping irrigation system

1. The water was dropped into soil near the root zone evenly and slowly.
2. The dripper can work under low working pressure.
3. The distance between two drippers can be chose by users.
4. Small flow rate, low loss by evaporation and good water-saving.
5. Small size of drippers makes installation and maintenance more convenient.

Knowledge of dripping irrigation system

How far should you keep the tube or tape away from the crops? You should know the soil texture is sand, loam or clay. Different soil texture has different infiltration rate. Besides that, you should also consider flow rate of dripper.

Clay loam sand Clay infiltration has shallow depth but wide diffusion
Loam infiltration has deep depth but narrow diffusion
Sand has the widest depth but narrowest diffusion.
Soil type Diffusion range on level
Coarse sand 15cm-46cm
Fine sand 30cm-90cm
Loam 90cm-130cm
Clay 160cm-180cm
1. Dripper flow affects diffusion range on the level. The bigger water flow is, the wide range of diffusion is. This is because the flow is very easy to form a saturated zone under the dripper, prompting the lateral diffusion of water.
2. The laying distance between dripping tube and dripping tape will affect the plants absorbing water and nutrient supply as well as affecting the impact of salt on plants.
3. The laying distance should be nearer in seedling period. For most conditions, the suitable distance to crops is 45cm. you can also adjust the dripper flow according to soil quality. For example, the distance should be narrowed to 30cm if the soil is sand.
4. The laying distance for mature crops can be widened properly as they have developed roots and can absorb distant water and nutrients.
5. Irrigation design and layout of young trees under different circumstances vary greatly from the mature trees. For example, vegetables have short growing time, so laying distance does not change with crop growth stages.

Drip irrigation uniformity

1. Uniformity of drip irrigation system is a very important technical indicator, which affects crop yield and quality.
2. Drip irrigation system can transport water and fertilizer into plants’ root zones and optimize plants’ living environment, by which the plants can reach high quality, high productive and high efficient. According to the research, we can find different demands to fertilizers for different crops and make plans for irrigation and fertilizing. Besides that, the uniformity of drip irrigation should be high enough in order to make crops get the same quantity’s water and fertilizer.
3. To improve the drip irrigation uniformity, we should choose drip emitters with excellent performance and on the other hand, the system designers should lower water pressure point as much as possible.
(1) Choose the right water pipe diameter, and set a reasonable length;
(2) choose reasonable pressure regulator equipment;
(3) Use Pressure compensation drop head or pressure compensation drip tape, drip irrigation pipe for undulating terrain ;

Applications of dripping irrigation system

It is mainly used for all kinds of orchard. It comes with pressure compensation greases, which is suitable for lands with undulating terrain and long pipe laying length. It has excellent anti-clogging performance.

Features of dripping irrigation system

1. Two flow rate, 4.0 and 8.0/h.
2. Range of working pressure: 100-300KPA
3. Turbulence form anti-clogging , the water balance Anti-clogging with turbulence, and hydraulic discharge is balanced.
4. Pressure compensation grease can anti corrosion.
5. Grease dripping bonnet and diaphragm can be removed, which is easy to be maintained.
6. 4mm bar inlet can prevent debris entering into the system while starting the system.
7. Grease diaphragm seat can prevent water coming back to the dripper while turning off the system.
