Mechanical treatment
① Peeling: peel off the epidermis before cutting to enhance the water absorption capacity of cuttings and promote hair roots p>
② Circular peeling: for example, Milan, gardenia, Osmanthus fragrans, rose, etc., the base of the branches shall be peeled in a circular way during the growth period, so that a large amount of nutrients can be accumulated in the girdling part. Cutting along the girdling part during the dormancy period can promote rooting p>
Heel cutting
That is to say, when cutting green branches, the lower part of the cuttings should be provided with a section like a human heel, which is conducive to the rooting of cuttings, as shown in the figure. For example, when cutting cuttings of Camellia, Osmanthus fragrans, fig and other flowers and trees, you can take a little last year's branches at the base of the cuttings, which is easier to take root p>
Increase the bottom temperature of the slotting bed
If it is a pot, it can be placed on a radiator or Kang padded with wood in winter. If conditions permit, the cutting effect is better by using electric heating hotbed p>
Use rooting powder
the base of annual shoots can be soaked with ABT rooting powder for about 0.5 ~ 1 hour, and then inserted into the matrix immediately after removal. ABT rooting powder is suitable for a large number of flower and tree cuttings, and its rooting effect is better than that of naphthylacetic acid and indole butyric acid div>Without rooting powder, it looks like 40 days after cutting p>
With rooting powder, it looks like 35 days after cutting! You can already see six white roots p>
Yellowing treatment
Before the growing season, cover the branches to be cuttings with black plastic bags to make them grow in dark conditions. After the branches and leaves grow to a certain extent, cut them for cutting. Yellowing treatment has a good effect on some flowers that are difficult to take root. Yellowing treatment of branches generally takes 20 days, and the effect is good p>
Water immersion method
For five needle pine, gardenia, Chlorophytum, oleander, rose, etc., the mother plant can be placed in the shade first, cut off after 10 days and inserted after soaking for a few days p>
See these small methods to promote rooting, is it easy to operate p>
