1. Water quality

The water in the pipeline is often used because of its guaranteed water quality. However, the tap water contains chlorine for disinfection and needs to be left for a period of time before it can be used, and water treatment is more difficult when a large amount of water is required. In addition, the same water temperature as room temperature is the most basic requirement in management, but it is difficult to control when the water consumption is large.

Except for the initial part, rainwater does not contain various other substances, so it can be said to be ideal water for greening. When building design, if possible, rainwater utilization technology should be actively promoted.

As the reclaimed water contains nitrogen and phosphorus, it is easy to form cohesive soil in the soil, which will cause the blockage of the irrigation device, so preventive measures must be taken. In addition, water with too much nitrogen will affect the normal growth of plants. In addition, there is no rainfall indoors, which can not wash the soil, which will easily cause the accumulation of fertilizer and salt. Therefore, reclaimed water with high nitrogen and phosphorus content should be avoided as much as possible when using it.

2. Watering method

If you use watering facilities, you only need to follow the method of use, and then check regularly. But if it is artificial watering, the experience and quality of the operator will directly affect the growth of the plants, which is mainly related to the operator's understanding of the soil characteristics, especially the use of natural soil. The appropriate level of artificial watering should be that the soil surface does not splash, do not accumulate water, or flow. However, if the watering intensity is weakened and the watering time is extended, the soil slope may not be infiltrated by water. Therefore, it is necessary to ask experienced staff to operate as much as possible, or strictly follow the requirements.

3. Interval time

As there is no rainfall indoors, the wind is weak, and the soil surface evaporates slowly. In this case, try to extend the watering interval as much as possible to allow the soil to dry and breathe air. The length of the interval varies according to the water retention of the soil and the humidity of the air, and it is sufficient to water it every 3-7 days. If you use nutrient solution cultivation or felt-type water-permeable cultivation, the interval can be extended accordingly. The watering time is appropriate in the morning when the plants have just woken up and there is little traffic.

4. Water volume

The amount of water to be watered varies according to the watering interval, soil water retention, and air humidity. The water volume should be controlled below the soil water retention, usually 10-201/m, so that a certain interval can be maintained. time.

5. Irrigation equipment

Under normal circumstances, a drip irrigation type irrigation machine with a timer is used, or an automatic control irrigation machine linked with a timer and a soil moisture detection device is used. The foliar water supply and cleaning of plants are mostly manual operations.
