1. Light management: during the maintenance process, the seedlings of Potamogeton crispus should avoid direct sunlight as much as possible. As it grows up, it's better to increase its illumination time. The average daily illumination time is 4.5-5.5 hours, which is good for its growth.
2. Water quality selection: Potamogeton crispus is a perennial submerged herb, so it generally appears in ponds, paddy fields, ditches and rivers. Therefore, there are many requirements for the nutrients in the sediment. The pH value of the water is generally from slight acid to neutral, which is conducive to growth.
3. Nutrient management: in the process of cultivating Potamogeton crispus, sufficient nutrients should be given, and the sediment and water quality nutrients should be sufficient.
4. Temperature management: the optimal growth temperature is about 15-20 ℃. If the temperature is suitable, flowers will bloom in April-May, and wither and rot in June.
1. Cutting: most of the cuttings are in the sediment, and the nutrients in the sediment and water quality should be sufficient. Increase the water level in time, and pay attention to the seedlings to avoid strong sunlight. Generally, cutting time can be in spring
2. Sowing: because it starts to bloom in April May, the most suitable sowing time is autumn, autumn begins to sprout, winter and spring belong to its growth period.
1. Withered and yellow leaves: if the symptoms of withered and yellow leaves occur, it is likely that the imbalance of pH value of water quality, over acid, over alkali, or excessive nutrition in water will easily lead to withered and yellow leaves. Should adjust acidity and alkalinity in time, maintain nutrition balance.
2. Rotten root: if there is rotten root in Potamogeton crispus, it is likely to be caused by insufficient oxygen in the water. Oxygen should be added in time to increase the light.
1. Toxic or not: Potamogeton crispus is a perennial submerged herb, which is non-toxic and has sufficient nutrients and is a good vitamin supplement.
2. Pruning and maintenance: due to the rapid propagation of its aquatic plants, it spreads all over the lake for a short time in a suitable environment, so it needs to be pruned every week to avoid excessive density.
