How to manage and protect soilless cultivated flowers

The main results are as follows: (1) controlling the temperature of nutrient solution. According to the requirements of different kinds of flowers, to ensure the appropriate liquid temperature of these flowers, so that the flowers grow well. Hydroponic flowers generally require a room temperature above 5 ℃ and a temperature below 30 ℃, and should not be exposed to the sun to prevent excessive liquid temperature from damaging the roots.

(2) pay attention to watering. When cultivating flowers in the substrate, the principle of replenishing water is to replenish water when the surface substrate is dry to 2 cm. The general growth period is watered once a week, each time according to the plant size, such as flowerpot inner diameter of 20 cm positive flowers, each time can be watered 100 ml of water. During the dormant period in winter or summer, it should be irrigated once every half month or one month. Tap water can still be used for water replenishment at ordinary times.

(3) pay attention to timely rehydration. According to the instructions of all kinds of nutrient solution, add it properly. Young seedlings are generally irrigated with nutrient solution every 15 to 20 days, while large seedlings are generally irrigated with nutrient solution every 7 minutes and 15 days. It is irrigated once a month in winter or dormancy. The amount of seedlings irrigated each time is less than that of large seedlings, and the amount of shade-tolerant flowers should be reduced.

(4) pay attention to changing the basin. When the plant grows too big, it is necessary to change the pot, and when changing the pot, the root system of the plant should be trimmed, which is generally cut off by about 1 root system, which is beneficial to the growth of new roots, and the matrix can also be partially or completely replaced with new ones.
