Method for planting gypsophila paniculata

The gypsophila paniculata can be cultivated by cutting, grafting and tissue culture.

In the production of cut flowers, tissue culture is mainly used for reproduction, which can be carried out all year round. The method is to wash the collected stem tips with clear water for several times, and then carry out routine disinfection for later use. Adding sucrose 30g/L to the culture medium; Agar 6g/l; MS medium with pH adjusted to 5,7 ~ 6,0. The culture temperature is (25 2)℃; Daily illumination 12 hours; Illumination is1~ 2kJ. On the medium, after about 4 weeks, clustered buds were formed, which were cut off and transferred to the medium for subculture. When adventitious buds grow in large numbers, rooting induction can be carried out. The tender stems with a height of about 2 cm formed in the process of subculture were cut off and transferred to the culture medium to induce rooting. After 4 weeks, most of them can grow new roots about 2 ~ 3 cm long. When the height of test-tube seedlings is about 3 cm and there are 4 ~ 6 new roots about 1 cm long, the medium used is vermiculite, which can be sown when 3 pairs of new leaves grow. Cutting propagation can be carried out all year round. Generally, it should be treated with auxin. Healthy and disease-free plants with strong growth potential are selected as mother plants, so 4-5 nodes of shoot tips are usually used as cuttings. The cutting matrix used is perlite. Firstly, the treated cuttings were soaked in water for 2 hours, and then the base of the cuttings was soaked in 0. Treat with 1% indolebutyric acid powder, then cut into the prepared seedbed at a proper distance, and seal the periphery of the seedbed with colorless plastic film, without watering for the first week. In the future, spray regularly to moisturize and avoid direct sunlight, and the shading rate is about 40%. The ambient temperature should be controlled at about 20℃.
