1、 Breeding environment

1. Water change: the water for hydroponic green pineapple needs to be changed regularly. It needs to be changed once every 2-3 days when it is just hydroponiced. After rooting, it can be changed once every 10-15 days, so as not to make the water quality turbid. In addition, don't put too much water when changing water, let 1 / 3 of the root system be exposed on the surface, and the leaves had better not touch the water

2. Illumination: it should be given proper illumination at ordinary times. It can't be exposed to strong sunlight. It's best to let it receive enough scattered light. If you breed indoors, put it in a sunny place, or move it outdoors regularly to bask in the sun

3. Temperature: for hydroponic maintenance, it should be given a growth environment of 20 ℃. The temperature should not be too high or too low. If the temperature is too low, it will be frostbitten. In addition, do not put it next to the direct blowing of air conditioner or heating

4. Nutrient solution: when raising green pineapple with water, add nutrient solution to it regularly, usually at the same time of changing water, add about 2-3 drops at a time. After the nutrient solution is applied, green algae will appear in the container, so it should be cleaned in time

2、 Precautions

Pay attention to the root system of the plant in hydroponic culture. Its root system will grow quickly in water. If the root system grows longer, it should be cut short appropriately. In addition, the root system is easy to rot in water. After the rotten root is found, it is necessary to clean the root system, cut off the rotten part, and disinfect it with potassium permanganate
