In this study, we have successfully built the process of breeding ancient rose trees in Hai Phong using the technique of cuttings. The process is as follows: Use a sharp knife to cut the middle part of the tedious cake branch on the ancient rose tree Hai Phong mother mastered to make cuttings, with a length of 8-10 cm. The cutting is treated to stimulate the root by dipping the cutting in the solution MD901 with a time of 5 seconds to stimulate the root cutting, then it is bronged into the husk price will reach a survival rate of 60.5% after 90 days of cutting. After the buds are turned on using Atonik fertilizer, sprayed with the amount of 10ml / 10 liters of clean water, sprayed in a dose of 5 days / time the ancient pink seedling will reach a height of 28.6 cm the number of new leaves reached 8.3 leaves after 90 days. The suitable price for planting hai phong ancient pink varieties is the price of hun husk + colored soil + Coconut fiber + chicken manure in the ratio of 1:2:1:1. The irrigation of additional synthetic fertilizer through Calcium XQ leaves + ACEGrow leaf fertilizer both ensures sufficient nutrition and economic efficiency, suitable for the growth of seedlings, ensuring the quality of seedlings. Use regular pruning to create canopies, increase the size of shoots, the number of shoots, the number of buds, the number of flowers, the size of flowers, the durability of flowers, seedlings to ensure quality until the garden is exported.
