Embodiment 1

[0034] Embodiment 1 A kind of rapid propagation method of arrow feather arrowroot

[0035] (1) Explant preparation and disinfection:

[0036] S11. Spray 3000-fold carbendazim every 7 days before seed collection on arrowhead explants, control water according to the growth environment, control water for 6 days before seed collection, and cut lateral buds according to the standard;

[0037] S12. Wipe the side buds with 75% alcohol, peel off a layer of bracts, cut off 0.5cm from the top of the side buds, and cut off 0.08cm from the bottom of the side buds, so that the side buds remain at a length of 3cm. After completion, put them in the sterilized In bottles, each bottle contains 1 / 2 volume of explants;

[0038] S13. Then add 75% alcohol to sterilize for 50 seconds, rinse twice with sterile water, and then transfer to 0.1% HgCl with 2 drops of Tween 80 2 Continue to sterilize, the sterilization time is 30min, pour out the disinfectant, pour in sterile water and wash 5 times.

Abstract

The invention relates to the technical field of plant cultivation, in particular to a rapid propagation method of calathea insignis. The rapid propagation method of the calathea insignis comprises thefollowing steps: (1) preparation and disinfection of calathea insignis explants; (2) induction culture of adventitious buds; (3) proliferation culture of shoot tips; (4) rooting to cultivate. Compared with the conventional dividing and cutting propagation technique, the rapid propagation method of the calathea insignis according to the invention can significantly improve the propagation coefficient of the calathea insignis, and the quality of obtained seedlings is stable, thereby solving the current situation of the shortage of high-quality calathea insignis seedlings.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a rapid propagation method of arrowroot arrowroot. Background technique [0002] Arrowhead arrowroot (scientific name: Calathea insignis Petersen ), also known as lanceolate arrowroot, mosaic turmeric, arrowroot family, Xiao arrowroot is a perennial evergreen herbaceous foliage plant, originating in Brazil and other places, is a tropical growing plant, its ornamental value And decorative effect are very high. [0003] There are generally two methods of propagation of Arrowhead arrowroot: branch propagation and cutting propagation. Branch propagation is more common for Arrowhead arrowroot, while cutting propagation is less compared to branch propagation. Arrowbane bamboo The optimum temperature for propagation of taro is about 20 degrees Celsius. If divisions are propagated indoors and the temperature and humidity are well controlled, divisions can be propagated throug...
