1、 Maintain temperature

During the cultivation of low lying pearls, the growth rate can be guaranteed only under the appropriate temperature. It is best to maintain it at 22-28 ℃. If the temperature is low, the growth will be limited. If it is difficult to reach the normal temperature for a long time, the aquatic plants may be damaged

2、 Sufficient fertilizer

Before planting, the laying of the bottom bed is very important. The bottom of the water tank shall be paved with water grass mud, which shall not be too thin. Only by ensuring the thickness can the grass take root deeply, but also adding base fertilizer to ensure sufficient nutrition and maintain the growth in the later stage. If the base fertilizer is difficult to guarantee, the subsequent growth will be worse and worse. When growing rapidly, it can be combined with changing water to supplement a little liquid fertilizer

3、 Proper water quality

The water quality for growth must be appropriate, which is the primary condition for its growth. The first thing to ensure is hard water. The pH of water quality should be maintained at 6.0-7.2, which should contain enough CO2. Also pay attention to the frequency of water change. Within the first four days, a quarter of the water needs to be changed, and it will gradually extend after 20 days

4、 Adequate lighting

We should also ensure good lighting factors. We can put a lamp next to the water tank to ensure that there is about 70 watts of lighting for every 100 liters of water, and there can be no light all the time
