1、 Water level
Because it mainly lives in places with water, so what we call water management mainly refers to the water level p>
Plants are in different growth stages, and the water level height 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 and promote the development of roots as soon as possible. With the growth of plants, the water level should rise slowly; When it comes to the most vigorous period, the water level should reach the maximum, which is conducive to the storage of nutrients p>
In addition, the water level should be adjusted according to seasonal changes. For example, in autumn, the water level should be lowered to allow it to receive sufficient light. When the weather turns cool in late autumn and early winter, the water level should be deepened to help it survive the winter better p>
2、 Topdressing
Principle: first, it is beneficial to the growth of plants. Second, try not to waste in water, otherwise the increase of nutrients in water will lead to pollution p>
Selection of fertilizer: we usually mix the fertilizer and clay in a certain proportion and then apply it into the water p>
Specific method: in order to achieve the above purpose, we can wrap the fertilizer with materials with good toughness and good water absorption, and tie several holes on the package, which is conducive to the release of fertilizer p>
Time selection: topdressing can be started 15 days before the full flowering period, and then every half a month or so to ensure the quality of flowering. However, it should be noted that each fertilization should not be too much p>
