(a) Choose to enrich disease-free shoots:
There are healthy and strong shoots for cuttings. "The good beginning is half of the success." Therefore, pests and shoots should be avoided. The leaves with rich leaves should be rich in nutrients, and they are more likely to be successful in cuttings.
(b) Prevent pest and disease invasion:
Diseases should be avoided in cuttings, pots, or cuttings. For example, black mold, branch blight, etc. can easily occur during cutting. Therefore, proper use of fungicides is essential.
(3) Water Management:
Due to the cuttings of roses, it is impossible to obtain the supplement of water from the mother plant. Therefore, to provide sufficient water to prevent the occurrence of withering, it is generally necessary to provide regular quantitative water supply and facilities above the simple greenhouse in order to be commercialized. In production, the control of moisture must pay attention to the humidity in the medium and the humidity of the air, in order to maintain the thin water vapor on the leaf surface instead of wet.
(d) Rooting agents to promote hair rooting:
To IBA1000-2000ppm can help rose cutting roots, we must pay attention to the concentration is too high but will not easily sprout axillary buds, so the appropriate concentration can make the cutting seedlings hair root is good, in addition to the above points are necessary for the propagation of rose cuttings There are other notes on the method and procedure.
(5) Other matters needing attention:
The middle section of cut flowers is more suitable for cuttings.
The three-leaf three-leaf cuttings were faster but the cost was higher than the single cuttings.
Cutting media can be formulated with peat soil plus pearlite.
To promote the germination of axillary buds can be added with BA containing nutrients or cryogenic low temperature treatment to break axillary bud dormancy.
Summer cuttings can take about 50-60 days to grow seedlings in about one month.
Cuttings in spring are prone to grow axillary buds and then grow roots, thus affecting their survival rate.
The use of warming bed treatment can promote the rapid rooting of cuttings in winter, and increase the reproduction rate.
Using sucrose preconditioning can promote the survival rate and the quality of nursery.
The trace elements Fe, Mn, and Zn also contribute to the survival of cuttings.
At present, the rose cultivation area in the country is about 236 hectares. Farmers need to renew planting every 3-4 years, and some farmers change their planting methods. In addition to the need for potted plants, about 6 million seedlings are planted annually for the initial estimate. Breeding methods provide fast and good rose seedlings, which not only benefits flower growers but also reduces the cost of production.
