FAQ

Traditional drip irrigation technology is designed with labyrinth flow channels to achieve anti-clogging. In order to prevent the accumulation of impurities in the irrigation water from clogging, it is necessary to ensure that the minimum spacing and considerable water pressure of the flow channels are required, i.e. both need a certain flow rate and a certain flow quantity. The working pressure of the final product on the market is generally not less than 5 meters, and the flow rate is generally not less than 0.8 liters / hour. As they reduce the numbers, the stability of the system also goes down. 

Because there is a lot of sediment in the rainwater, even after the use of sedimentation, its suspended particles will soon be deposited in the flow channel to cause clogging, low-pressure (gravity) irrigation using rainwater is clogged even faster, so there is no similar product on the market.

Due to the slow outflow rate, the diffusion and transport time of water in the soil is prolonged under the same irrigation volume, so that the irrigation water tends to be more evenly distributed in the soil of plant roots, creating a good soil three compared to and root environment, which is conducive to the robust growth of plants. Moreover, the water outflow rate is close to the water absorption rate of plants, and the water outflow can be absorbed by plants in time, which significantly reduces surface evaporation and deep seepage while ensuring the water demand of plants.

The dangers of under-irrigation (drought) are well known, but the dangers of redundant irrigation are often limited to the harm caused by prolonged soaking of the root system. In the use of low flow rates we have found that only the amount of water that relies entirely on soil capillary diffusion is appropriate for the plant, and anything beyond that is actually redundant. These irrigation redundancies can be more or less a burden to green agriculture. For example, it is very important for green agriculture that the soil maintains an optimal environment for root growth, promotes plant health, and keeps plants free of disease (which was not possible with irrigation in the past, but only with a lot of outside intervention. Greenhouse to suppress high humidity to increase the exhaust air, will increase the difficulty of temperature control; once on the disease will face the dilemma of rather reduce the yield of extinction than the use of drugs. (Solving these problems through facilities and management will significantly increase the cost of green agriculture).

​

Low-flow irrigation fundamentally eliminates these hazards, while requiring minimal facility inputs and management. Low-flow irrigation is best for the health of crop roots, and healthy plants are less likely to get diseases, so low-flow irrigation can produce the best quality fruit with little to no pesticides or fertilizers. It is believed that low flow will become the support of green agriculture and the cropping system will be based around low flow irrigation.

​

Air humidity decreases, reducing the risk of disease to crops. In the fields using trace irrigation, due to the improvement of cultivation environment brought by the change of irrigation method, crops are less likely to have, or do not have, various diseases that are easy to occur in other cultivation methods, thus reducing the use of chemical pesticides, especially highly toxic pesticides, and the number of times they are used. Under the new water-saving irrigation method of trace irrigation, it is more suitable for the production of various green and organic agricultural products, which greatly reduces pesticide residues in agricultural products and the health risks associated with people's consumption of agricultural products.

Through our long-term observation of subsurface irrigation, the main reasons for the occurrence of emitter blockage due to root intrusion are:

1. The flow rate of emitter is too large; the soil regularly alternates between wet and dry. Every time the soil moisture is too low, the emitter’s high humidity will have an attractive effect on the root system. Eventually the emitter is covered with many roots around, and only one time of not timely irrigation, the root system will invade.

2. It often happens that the root intrusion is not the cause of the emitter blockage, but the result. That is, the emitter is first clogged internally, the flow rate becomes small, resulting in a lack of soil moisture, forcing the root system to enter the emitter to only "find water".

Self-cleaning irrigation has a small flow rate, so that the rate of water discharge matches the exact rate of soil diffusion. The soil three components (soil, water, air) are always maintained at the optimal level, creating the most comfortable environment for plants’ roots. The high humidity in the emitter becomes instead an environment for the roots to avoid entering. At the same time the emitter itself does not become clogged, which removes all incentive for root invasion.

Therefore, this small flow rate and non-clogging irrigation technology is the best method to prevent root intrusion.

​

For Self-cleaning irrigation, it is not necessary to stop irrigation. Just make sure that there is always water in the system. Lower the pressure and the emitter will irrigate continuously at a correspondingly low flow rate (e.g., 50 ml/hour, 1.2 L/day at 0.7 psi) to maintain optimal soil moisture without the chance of root intrusion. 

The cost is lower than drip irrigation because the flow rate is extremely low and the self-cleaning irrigation pipe diameter can be very thin, so the cost is naturally lower. It can be understood that drip irrigation spends most of its time in a non-working idle state, which is an ineffective cost resulting from the thick pipes. The low flow rate technology greatly improves the utilization of the pipe and saves this inefficient cost, so self-cleaning irrigation is not only less expensive, but also a great contribution to the environment.

Of course. Previously, water conservation in lawn has been a big problem because the most water-saving drip irrigation is too large in volume to be used on the lawn surface. The inner diameter of self-cleaning irrigation pipe can be less than 2.5 mm, which can be embedded directly from the lawn surface at the grass root, invisible from the outside, and does not affect the surface weeding and walking, installing and dismantling are very convenient, easily realize lawn micro-irrigation.

1. Self-cleaning irrigation can be used underground without clogging at low flow rates, although there is no problem with surface use, but buried in the ground can show more outstanding advantages. Due to the slow speed of water discharge, the diffusion and transport time of water in the soil is prolonged under the same irrigation volume, so that the irrigation water tends to be more evenly distributed in the soil of plant roots, creating a good soil three compared to the root system environment, which is conducive to the robust growth of plants. Moreover, the rate of water discharge is close to the rate of water absorption by plants, and the outflow water can be absorbed by plants in time, which greatly reduces surface evaporation and eliminates

deep seepage while ensuring the water demand of plants. Numerous studies have shown that trace irrigation uses less than half the amount of water used by drip irrigation.

​

2. Because the flow rate is extremely low, the length of trace irrigation capillary laying can be more than 500 meters, which substantially increases the single well irrigation area, reduces or eliminates the rotation irrigation and reduces the field input.

​

3. Because the fertilizer goes with the water, saving water and at the same time making the utilization of fertilizer to the maximum, completely eliminating pollution and waste from excess fertilizer.

​

4. Traditional furrow irrigation of greenhouses and greenhouses, a large amount of irrigation, the surface of the ground for a long time to keep wet, not only the room temperature, ground temperature fell too quickly, the slow recovery, and evaporation increased, indoor humidity is too high, easy to lead to vegetable or flower pests and diseases. As trace irrigation can supply water to the root soil layer evenly and slowly, it has obvious effect on ground temperature maintenance, rebound and reduce water evaporation, and reduce indoor humidity. Air humidity decreases, reducing the damage caused by pathogens to crops. In the fields using trace irrigation, due to the improvement of cultivation environment brought by the change of irrigation method, crops are less likely to have, or do not have, various diseases that are easy to occur in other cultivation methods, thus reducing the use of chemical pesticides, especially highly toxic pesticides, and the number of times they are used. Under the new water-saving irrigation method of trace irrigation, it is more suitable for the production of various green and organic agricultural products, which greatly reduces pesticide residues in agricultural products and the health risks associated with people's consumption of agricultural products. Trace irrigation slowly irrigates the soil, the soil water, soil and gas are in the right ratio, which is conducive to creating a good root soil environment, promoting the growth of a large number of lateral roots and capillary roots, facilitating the absorption of water and fertilizer, and the plants grow strong; trace irrigation soil is loose and the surface is dry, so weed seeds cannot germinate; there is no need for frequent mid-tillage and weeding, which also reduces secondary salinization caused by surface evaporation. Trace irrigation can keep the soil loose and airy, and supply the right amount of water and fertilizer continuously and steadily, so the plants grow vigorously and the products have good flavor and high consistency, which is conducive to high quality and price.

5. Help mankind to further improve the deep understanding of plants. People have been studying deficit irrigation for a long time, but without precise control of water, there is no accurate regulation of soil moisture. Trace irrigation is able to supply water precisely at a rate that matches the water needs of plants. Although it was known in the past that the most suitable water for plant uptake is the capillary suspension water in the soil, what effect does a different water content between the wilting factor and field water holding capacity have on plant growth, what water content is more beneficial in promoting plant secondary metabolites (secondary metabolites) at what period of time, under what conditions on quality, under what The lack of precise water supply technology has made it impossible to study in depth the effects on flavor. Trace irrigation provides the ideal tool to precisely regulate the upper and lower limits of plant water requirements, allowing researchers to obtain arbitrary results, which will certainly give a new impetus to the development of soil science and botany.

6. In California, there is a large amount of barren land, and by burying the new trace irrigation underground, it is possible to maintain a moist environment below the surface of the ground with little water, and it is easy to use in the wilderness by gravity irrigation only, without power supply, and completely change the condition of the landscape.
