How to hydroponically cultivate and preserve colored leaf begonia?

Colored leaf begonia belongs to Begonia, with obliquely oval leaves, bright green leaves, red veins, scarlet or light red flowers, and perennial herbs. As shown in the figure.

1. Hydroponic method

(1) method 1: select the seedlings of Begonia angustifolia with good plant shape, wash the soil, cut off the withered shoots, dead leaves and rotten roots, disinfect the roots with 0.1% potassium permanganate solution for about 10 min, rinse the roots with clean water, plant them in a transparent container, and inject clean water into the root system. Change the water once in 1-2 days, and water bacon can grow in 5-10 days.

(2) in the second method, the robust branches of Begonia were cut, dried for half a day or 1 day, directly inserted in clean water, changed into water once in 1-2 days, and water bacon could grow in 1-2 weeks.

2. Maintenance guidelines

The main results are as follows: (1) the light and temperature should be cultivated in the bright light on weekdays, and the strong light should be avoided. When the strong light shines directly, the leaves will contract and turn red and purple. When the temperature reaches 32 ℃, it grows slowly and enters dormancy. It should be moved to a cool and ventilated place and cultured with clean water. When the temperature dropped in autumn, the culture was resumed with nutrient solution. It can continue to grow and blossom when it is placed in a bright light place and keep room temperature above 15 ℃ in winter, and it can survive the winter safely above 5 ℃, and stop the application of nutrient solution.

(2) the fresh water was changed every 2-3 days, and the new roots were grown. The new roots were cultured in flowering plant nutrient solution or comprehensive nutrient solution, and the nutrient solution was changed once in 2-3 weeks.

(3) pruning in the small pong period of Qiuhaitang, according to the growth situation, to pick the heart or cut it short to promote lateral branches to facilitate flowering. Remove the flower branches in time after flowering, and trim them.
