Branch selection: cutting branches with buds and buds with the length of15 ~ 25cm from the mother plant, and bundling 50 branches into a bundle for later use; To build a waterbed, it is necessary to build a waterbed with a length of1.2m and a length of15 ~ 20cm. Hydroponics method: the pruned branches can be inserted into the waterbed, with the first section of the stem facing upwards, and then enough water is poured; In the later curing, the room temperature should be stabilized at10 ~15℃, and all-weather astigmatism irradiation should be given.

1, branch selection

In the process of hydroponic maintenance of thorn buds at home in winter, it is necessary to cut strong branches from the mother plant, and the length should be controlled between15 ~ 25 cm, and the branches should be provided with buds and flower buds to improve the survival rate of the transplanted plants. In addition, it is necessary to cut 45? Cut a knife diagonally at the corner, and after disinfection, bind 50 branches into a bundle, which will be used after disinfection.

2. Establish a waterbed

In winter, when maintaining thorn buds at home, it is necessary to build an effluent bed in the greenhouse, with the specification controlled at1.2m, north-south orientation, the bed spacing controlled at about 30m, the step width along the back wall of the greenhouse controlled at 70cm, and a distance of 0.5m along the edge of the greenhouse, and dig out a drainage ditch, so as to better discharge water when changing water. The height of waterbed should be controlled at15 ~ 20cm to ensure the smoothness of seedbed.

3, hydroponics method

In the process of hydroponic maintenance of thorn buds, it is necessary to put the trimmed stems into water, and the head end of the stems needs to propagate upwards. After placing, it is necessary to loosen the upper part and irrigate enough water. After watering, the stems should be treated with carbendazim and gibberellin solution to make them germinate and grow as soon as possible.

4, the later maintenance

After the completion of cultivation, the indoor temperature should be stabilized at10 ~15℃, and all-weather astigmatism should be given during hydroponics to maintain normal growth. In the low temperature environment in winter, it is necessary to change the water every 10 day, and after the temperature gradually warms up, it is necessary to change the water every 10 day. In addition, during the curing period, it is necessary to ensure the ventilation of the environment to avoid spots on the leaves, and to apply thin liquid fertilizer once a month to supplement nutrition.
