I want to use water tower drip irrigation, and I want to ask for relevant knowledge and technology.

This should refer to gravity drip irrigation.

The ordinary drip irrigation system mainly includes the water source, the head, the water pipeline and the irrigator.

If the water source is a water tower, theoretically speaking, the height of the water tower should be determined according to the working pressure of the irrigator used, the hydraulic loss in the filter and the water pipeline, and generally should be greater than 10 meters. Of course, if the uniformity of irrigation is not required, this height can also be appropriately reduced.

The first system mainly includes filtration equipment, water volume and pressure measurement device, fertilization equipment and related valves. To do drip irrigation, filtration is essential because once the drip irrigation device is clogged, the drip irrigation system is unusable. As for the fertilization equipment, it is optional, if there is a condition, it can be matched, drip irrigation fertilization is more efficient than ordinary fertilization, and it is more convenient, of course, we should pay attention to the selection of water-soluble fertilizer.

The water pipeline is generally PE pipe or PVC pipe, and according to the actual situation, the corresponding pressure level and pipe diameter are selected.

Drip irrigation irrigators are commonly used in drip irrigation belts, drip irrigation pipes, pipe drippers, etc., and each one has a variety of specifications and models, and then according to the actual conditions to select the corresponding products.

Do you mean self-compressing drip irrigation? The water is lifted to a high place and then irrigated by self-pressure of the water flow.

Hello dear dear, the detailed introduction of the existing drip irrigation is as follows: according to the arrangement of the capillary in the field in the drip irrigation project, whether it moves or not, and the way of irrigation, the drip irrigation system can be divided into the following three categories: 1. The ground fixed capillary is arranged on the ground, and the system that the capillary and irrigator do not move during irrigation is called the ground fixed system, and now the vast majority of this kind of system is adopted.

Used in the irrigation of orchards, greenhouses, greenhouses and a few field crops, the irrigator includes a variety of drippers and drip irrigation pipes, belts. The advantages of this system are that it is easy to install and maintain, and it is also convenient to check soil moisture and measure the flow change and balance of the dripper; The disadvantage is that the capillary and irrigator are prone to damage and aging, which also has an impact on field farming. 2. The underground fixed system that buries the capillary and irrigator (mainly the dripper) into the ground is called the underground fixed system, which is the continuous improvement and improvement of drip irrigation technology in recent years, and the irrigator blockage is reduced, but the application area is not much.

Compared with the ground fixed system, it has the advantage of eliminating the work of capillary installation and disassembly before and after crop planting and harvesting, does not affect field tillage, and prolongs the service life of the equipment; The disadvantage is that it is not possible to check the soil wetting and measure the change in the flow rate of the dripper, and it is difficult to repair when there is a problem. 3. Mobile During the irrigation period, the capillary and irrigator are moved from one position to another after the irrigation is completed, and the system is called mobile drip irrigation system, and this system is also less used by people who worship the shed. Compared with the stationary system, it improves the equipment and utilization rate, reduces the investment cost, and is often used for bright potato field crops and crops with less irrigation times, but the operation and management are more troublesome, and the management and operation costs are higher, and it is suitable for use in areas with drought and water shortage and poor economic conditions.

It's my pleasure to help you solve your problem! Hope to get your trouble in the bottom left corner of a like thanks

Hello, dear, the existing drip irrigation technology is to use plastic pipes to send water through the orifice or dripper on the capillary with a diameter of about 10mm to the root of the crop for local irrigation. It is one of the most effective water-saving irrigation methods in arid and water-scarce areas, with a water utilization rate of up to 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing yield, and can be combined with fertilization to improve the fertilizer efficiency by more than double.

It can be applied to the irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for field crop irrigation in drought and water shortage places. The disadvantage is that the dripper is prone to scaling and clogging, so the water source should be strictly filtered.

1. Local irrigation, drip irrigation only moistens part of the soil, and the crop rows are kept dry.

2. High-frequency irrigation, drip irrigation slowly and continuously supplies water to the root layer of crops, generally irrigating water every day or every few days of Tanli bush for a period of time, so that crop roots are often kept at the most suitable amount of water.

3. The working pressure of the drip irrigation irrigator is mostly about 100 kPa, so as to realize the low-pressure pipeline water transportation.

The main organ of the plant to absorb water is the root, and the main part of the root water absorption is mainly the mature area of the root tip, and the mature area has a large number of root hairs, which can absorb water Sprinkler irrigation and drip irrigation are emerging water-saving irrigation methods, and these irrigation methods are mainly to improve the water supply to the noisy roots

Therefore, d

1. Local irrigation, drip irrigation only moistens part of the soil, and the crop rows are kept dry.

2. High-frequency irrigation, drip irrigation slowly and continuously supplies water to the root layer of crops, generally irrigating every day or every few days for a period of time, so that the crop roots are often kept at the most suitable amount of water.

3. Low-pressure irrigation, drip irrigation irrigator The working pressure is mostly about 100 kPa, and the low-pressure pipeline water transmission is realized.
