Main irrigation methods for vineyards

Grapes have a relatively high drought tolerance, and is generally most suitable to areas with an annual rainfall of 600-800 mm. In these areas, as long as moisture conservation is done properly, a good amount of grapes can be produced even without irrigating them the entire year. In grapes moisture management, there are three critical irrigation periods throughout the year. The first one is after bud break. This helps ensure that the crops grow neatly and the new shoots are strong; the second irrigation period is during veraison. This ensures that the berries and new shoot grow well; the third period is at the beginning of winter before the soil freezes. This helps the roots and the trunks to live through winter safely. The following are the main irrigation methods used in vineyards: 1.Furrow irrigation: this has been the most popular irrigation method for vineyards around the globe [...]

Intelligent Sprinkler Control System

Benefits Of Intelligent Sprinkler Control System The intelligent sprinkler control system is a system designed and developed to reduce the amount of irrigation water used and to achieve smart and intelligent control in agriculture. The intelligent sprinkler control system is controlled using programmable controllers, and combines microcomputing technology with traditional relay and contactor control technology. It overcomes the shortcomings of a relay and contactor control system, such as their complex wiring, low reliability, high power consumption, and low versatility, while also solving the issues of a computer control system such as its environmental requirements and high costs.  Programmable controllers make use of the programmability of microprocessors. It does not require specialized knowledge of programming language, but rather uses a simple method of instruction based on a set of relay ladder diagrams, so that the programming experience is visual, intuitive and easy to learn. Both toning and error-correction are convenient. After [...]

Technical Introduction to Fertigation

Brief Introduction of Fertigation Fertigation is a new agricultural technology that combines irrigation and fertilization. Fertigation technology uses a pressure system (or a height difference in the terrain), to combine soluble solid or liquid fertilizers with irrigation water, according to the soil nutrient content and the nutritional needs of the crop, and through the help of a controllable pipeline system. When the fertilizer has been integrated into the irrigation water, it then evenly, regularly, and quantitively waters the growth and developmental root zone of the crops, through the pipeline and the drippers. This allows the root soil to remain loose and to maintain the appropriate water content. It also allows farmers to design the fertigation system according to the characteristics of different vegetables, the soil environment, the current nutritional state of the crops, the water demand of vegetables in different growth periods, and fertilization cycles, so that the crops receive a proportional [...]

Drip Irrigation System Maintenance

Here is some tips for maintenance the drip irrigation system at the en of each irrigation season : 1) Washing the entire drip irrigation system with high pressure: Open a number of valves of the rotational flow group (less than the number of valves used in regular rotational flow), open the pump, open the plugs and capillaries of the principal and secondary pipe successively, pressure washing each rotational flow plot, in order to clear the dirt accumulated in the pipelines. Finally, put the plug back and close the capillaries. 2) Filtration system: after washing the pipeline with pressure, fully clean the filter and drain the water 1.If your filter is a laminated filter with a gravel separator: first, please clean every group of laminate assembly, then dry the seal inside the plastic case with a dry towel, and put it back inside. Afterwards, unscrew the screwed plug located on the [...]

Operating principle and common malfunctions analysis of solenoid valves

1) Operating Principle of solenoid valves Currently, most of the solenoid valves used in the fields of agriculture and landscaping are diaphragm valves. The diaphragm valve consists of an upper chamber, a lower chamber and a diaphragm in between them. Due to a difference in thrust surface area on the two sides of the diaphragm, a pressure difference will be created under an equal amount of water pressure, and ultimately achieving its purpose of shutting off water flow. Opening  the solenoid valves: by sending an electric signal through a remote controller or by manually rotating the solenoid, the drain channel will open, releasing the water in the upper chamber, thus reducing the indoor pressure and lowering the pressure exerted on the top of the diaphragm. Under the upstream pressure, the diaphragm will be raised, ultimately releasing the pipeline channel. Closing the solenoid valves: manually closing the solenoid or disconnecting [...]

How to Install Irrigation Solenoid Valve

Irrigation Solenoid valve or just “solenoids”—are the primary instrument of control for today's automated irrigation systems. Solenoids direct water flow by opening or closing according to an electrical signal issued by the control system.  Most solenoids automatically default to the closed position and remain so when the electrical circuit is shorted, and then open when the circuit is completed and a signal is delivered. IrriRich 3-way irrigation solenoid valve are different: our valves are adjustable, and may be set up to open by default. All IrriRich valves come in 6 to 7 sizes, ranging from 1/8 to 4 inch diameters, and our lowest opening pressure starts at 6 PSI. IrriRich solenoids can be conveniently used at ordinary temperatures, and we provide some specialized valves for use iin river, lake, and waste water applications. Finally, IrriRich has also developed effective mine and anti-rodent valves which give irrigation systems cost-effective, [...]

Solenoid Valves: Increase Efficiency And Economy For Irrigation Systems

In agriculture, the economics of water supply-and-demand is driving the development of water conservation controls in irrigation systems. Across the entire world these pressures have made the improvement of the lowly hydraulic valve a key cost-saving concern. Here, we present the types of valves most often used when building irrigation systems, and briefly touch on their different features. The most important considerations when selecting valves are quality, field reliability, and the suitability of design. Yet replacing a bad valve with a better one may be a simple but invaluable upgrade that permanently resolves costly recurrent failures and inadequacies. Gate Valves Also called sluice valves or shut-off valves, gate valves are typically used at the main water feed, or at the entry points to subsections of a field independent to other areas. A gate valve operates by sliding a flat- or wedge-shaped gate into a seating array much like a gate [...]

Rodent Menace Bit The Valves In The Agriculture System

There is a saying that “By gnawing through a dike, even a rat may drown a nation”. This is the power of rats and their family of rodents. With rodent population growing 10X faster than humans, the riot caused by them is also escalating at an equal pace. Polymer products are particularly affected since they cannot endure the attack by rodents. The article aims to demonstrate the rodent menace to the irrigation system especially to the agricultural valves, and the progress Irririch has made to protect the plastic hoses from rodent biting attacks. Rodent menace: The number may be intriguing but true; forty percent of mammal species found on earth are rodents. Scores of rodents are found on all continents other than Antarctica. Common rodents include mice, rats, squirrels, porcupines, beavers, guinea pigs and voles. Rodentia is an order of mammals also known as rodents, which is characterized by two [...]

Technology is Expected to Improve the Efficiency of Irrigation

Science and Technology is expected to improve the efficiency of agricultural irrigation under the condition of water shortage in the future Water is limited but key important resource. On the most drainage basins in the world, water is essential for the industry, city and residents' life. Meanwhile, water also plays a very important role in the natural system. But from the view of the world, most of water resource is used in the agricultural production----In the water resources of human allocated from nature, 66% are used in agricultural production. In the water shortage area of western US it is not rare to see that the total irrigation water accounted for 75-90% of the total diversion water. From the view of history, many water diversion projects are funded by the government in US. Besides, the water rights mechanism also give priority to ensure to supply agricultural water, this causes low price [...]

Anti-Freeze Protection For The Irrigation Systems

Anti-freeze protection of the irrigation systems is actually to discharge the water from the pipes, solenoid valves and sprinklers before they are frozen. The anti-freeze measurements are different under different climates, but generally there are below 4 kinds of measurements: 1、manual discharge measurement, discharge the water from the system 2、automatic discharge measurement, discharge the water from the system 3、compressed air measurement, blow the water from the irrigation system 4、anti-freeze material wrapping the pipes (generally used on the ground pipes) The current domestic anti-freeze systems are mostly bury the pipes below the freeze soil layer, as a result: the system is safe and the management is simple, but it is a huge project to bury these pipes and the investment is bigger. For example, the frozen soil layer in Beijing is 50cm~80cm, while the general channel projects are of 1m depth. Pipe systems in Xinjiang area is approximately 1.8m. The basic [...]
