Because it mainly lives in the place where there is water, so the water management we say mainly refers to the water level
Plants are in different growth stages, and the water level to be controlled is also different. For example, when it is in the early stage of growth, its petiole is relatively short, so the water level should be as shallow as possible, and the leaves should not be exposed to the air, so as to improve the water temperature as soon as possible and promote the development of roots. With the growth of the plant, the water level will gradually rise a little; when it comes to the most vigorous period, the water level will reach the maximum, which is conducive to the storage of nutrients.
In addition, the water level should be adjusted according to the seasonal changes. For example, in autumn, we should lower the water level and let it receive enough light. When the weather turns cold in late autumn and early winter, we should deepen the water level to help it better winter.
Principle: the first is beneficial to the growth of plants, the second is to try not to waste in the water, or the increase of water nutrients will lead to pollution.
The choice of fertilizer: we usually mix the fertilizer and clay in a certain proportion and then put them into the water.
Specific method: in order to achieve the above purpose, we can use the material with good toughness and good water absorption to wrap the fertilizer, and tie several holes on the package, which is conducive to the release of fertilizer.
Time selection: topdressing can be started 15 days before flowering, and then every half a month or so to ensure the quality of flowering. However, we need to pay attention to each fertilization should not be too much
