Reproduction, harm and economic value of the five-jawed golden dragon flower

Seedlings can be divided when the two leaves are unfolded. The five-clawed golden dragon usually breeds with seeds, has a large seed volume, high germination rate, easy breeding and rapid growth. In China, it only blooms in Guangdong, and it is rarely sturdy. It mainly uses stems for asexual reproduction, and can grow vegetatively throughout the year.


Hazard prevention


For the five-jawed golden dragons growing in non-crop areas, the following two herbicides can be used to eliminate them:


1, 10% glyphosate water 1000-1500 ml, 30-40 kg water, spray evenly on the leaves and tender stems of the five-jawed golden dragon.
