How to use water-saving irrigation equipment in tea gardens
Application of water-saving irrigation equipment for tea garden irrigation
1. Irrigation of tea gardens
Since the 1970s, sprinkling irrigation in tea gardens in my country has begun to grow. Production practice has proved that water-saving irrigation equipment is a relatively advanced irrigation method for tea gardens.
The tea garden sprinkler irrigation system is mainly composed of water source, channel system, water pump, power, pressure pipeline and sprinkler. According to the different combination modes, it can be divided into three types: mobile, fixed and semi-fixed. The mobile sprinkler irrigation system is composed of power equipment, pressure water pipes and sprinklers, and is set in tea gardens with water sources. The device has the characteristics of sensitive use, low investment, simple operation and high utilization rate. However, handling and moving takes more time. Except for the sprinkler, the fixed sprinkler irrigation system is fixed, and its main and branch pipes are often buried in the soil layer of the tea garden. The pumping station is composed of water source, power machine and water pump, or a dry pumping station with a natural water head with sufficient height is selected. The branch pipes constitute a set of fixed sprinkler irrigation system. The sprinklers are mounted on straight pipes that join the branch pipes and can be used as circular or fan-shaped rotary sprinklers. If the area is large, it needs to be equipped with several groups of sprinklers to irrigate in cyclic groups. The utility model has the advantages of simple operation, labor saving, high production efficiency, convenient automatic control of irrigation and the like. It is suitable for tea gardens and nurseries with a long irrigation cycle, but requires more equipment and pipes and higher i

What are the benefits of micro-sprinkler atomization irrigation technology?
1. What are the advantages of the application of micro-sprinkler atomization irrigation technology?
1. Micro-spray irrigation saves water and fertilizer and reduces energy consumption. Using micro-nozzle (refractive atomizing micro-nozzle) irrigation technology to irrigate crops, the water spray volume is small (40L/h), the irrigation range is wide, the average water consumption is low, the pressure of the micro-nozzle irrigation system is low, and there is no need for large pressure devices. Low energy consumption After being filtered by the micro-nozzle, the crops are sprayed and irrigated through the micro-nozzle, and fertilization is applied to the roots and foliage of the crops at the same time, which improves the utilization rate of fertilizers. The use of refractive atomized micro-sprinkler irrigation saves more than 70% compared to traditional ground irrigation, saves more than 30% of fertilizer, and saves about 50% energy compared to large-scale sprinkler irrigation.
2. Micro-sprinkler irrigation technology has the advantages of increasing production, improving product quality and increasing benefits. Under the conditions of micro-sprinkler irrigation, the use of ground-plug refraction atomization micro-sprinkler irrigation can increase the yield of citrus by more than 30%, the yield of apples by 20%~30%, the yield of black fungus by 1~2 times, and the yield of pepper by 30%~40%.
3. Refraction type atomizing micro-sprinklers or double-sided wheel-type micro-sprinklers can be used for irrigation. The spray radius is large and the atomization effect is good. Compared with micro-drip irrigation, the drip irrigation belt, dropper and dripper are less affected by terrain , can meet the irrigation needs under different conditions.

Do fruit trees need flooding?
To encourage fruit farmers to implement water-saving irrigation instead of flood irrigation, we must first deal with the problem of farmers' ideological understanding, and then talk about flood irrigation. Fruit trees don't need that much Fruit trees need water to some extent, too much or too little is bad. We know that the soil is a complex of water, fertilizer, air and heat. There are suitable proportions of outstanding soil elements. If there is too much water, it will inevitably affect the other three aspects. It will be difficult to breathe, and the severe root system will also lead to the death of the root system; when there is too much water, it is difficult to increase the soil temperature, and the lower temperature is not conducive to the growth of fruit trees. In addition, some active nutrients will also be lost with water or enter the deep soil. Therefore, fruit trees do not need too much water. Generally speaking, the soil water content can reach 45% of the field water holding capacity, which can meet the needs of fruit trees. For some thriving trees, moderate water control is sometimes required to facilitate the flowering of fruit trees.
In this regard, Professor Wei Qinping, a famous fruit tree expert in my country, made such an interesting experiment, that is, planting an apple tree in the middle of four square flower pots, that is, dividing the root of the fruit tree into four parts and watering it. The results showed that fruit trees in one pot at a time (i.e., one-quarter watering) had little vegetative growth and easily formed flowers. Each time four pots are watered, the fruit trees (ie, four-molecular four-watering) grow very large, with vigorous branches and leaves, but it is difficult to form flowers. The test results show that moderately controlled irrigation can achieve the desired effect.

How important is the intake and exhaust valve for water-saving irrigation equipment
Inlet and exhaust valve planning In the irrigation planning and construction process of farmland or garden, pipeline exhaust and water inlet are often neglected or improperly installed, resulting in pipeline safety accidents.
1. Where does the gas in the pipeline come from?
1. Before the irrigation system is built, the pipes are filled with gas. After irrigation, most of the gas is discharged through the transmitter or inlet valve, and some gas cannot be discharged at the high point of the pipe.
2. Part of the air dissolves in water. When the water temperature rises in summer, the dissolved air in the pipeline water will be deposited, and the air separated from the inner wall of the pipeline will gradually gather at the high point of the pipeline.
3. Because the negative pressure of the pipeline is inhaled by the safety valve or the intake and exhaust valve, and then the gas in the pipeline is inhaled.
2. The working principle of the intake and exhaust valve
The quick exhaust valve is designed according to the principle of the buoyant effect of water on the stainless steel float. When the water level of the exhaust valve rises, when the exhaust valve is exhausted, the floating ball automatically floats until it is connected to the sealing surface of the exhaust port. The ball closes automatically under certain pressure. When the water level in the valve drops, the ball will drop with the drop of the water level and inject a lot of air into the pipe through the exhaust port. When the pipe is running, the float stops at the botto

Advantages of pressure-compensated dripper
The pressure-compensated dripper uses the pressure of the water flow to deform the elastic parts or the flow channel, which causes the cross-sectional area of the water to change, realizes a stable flow, can automatically adjust the water output and self-cleaning, and has high water uniformity, but the manufacturing process is more complicated and the price is high. ; And the performance of the elastic material is directly related to the pressure compensation characteristics of the dripper. Only when the performance stability of the elastic material is equivalent to that of the dripper material, can the entire dripper work stably for a long time.
The pressure-compensated dripper can keep the flow rate of the dripper basically unchanged in a larger pressure range, thus increasing the adaptability of the dripper to complex terrain.
In addition, when pressure-compensated drippers are used, the number of drippers arranged in the same branch can be greatly increased, and the number of branch pipes can be reduced accordingly, thereby reducing the cost of the pipe network, and being insensitive to temperature changes, which is beneficial to ensuring and stabilizing the uniformity of irrigation.
