Latest Management Techniques and Methods Tutorial After Grafting Loquat
Fruit tree grafting requires mastering certain techniques, and loquat is no exception. If the grafting time or method is wrong, it will cause grafting failure. In addition, if post-grafting management is not kept up, grafting failure often occurs. So how should loquat be managed after grafting? Follow the editor to take a look.
1. Check the survival rate
Generally, 20-30 days after grafting, you can tell whether the scion has survived. You can check from the state of the grafted bud and petiole. If the grafted bud is fresh and the petiole falls off at a touch, it indicates that it has survived. For example, if the grafted bud is shriveled, scorched yellow in color, or the grafted bud has already dried up, and some scion tips turn black, it indicates that it has not survived. For scions that have not survived, timely re-grafting should be carried out.
2. Break the film and expose the buds
When the grafted bud begins to sprout, carefully use the tip of a knife to pierce the grafting film that hinders the sprouting of the grafted bud. For example, if the grafted bud has survived, after untying the film strip for 7-10 days, cut the rootstock above the grafted bud to four-fifths of its diameter, twist it off at the cut, so that one-fifth of the rootstock bark and stem remain connected, allowing water and nutrients to flow between the upper and lower parts. When the grafted bud sprouts and sends out secondary shoots, and when there are at least 4-5 mature large leaves on it, after the new shoot stops growing, cut off all branches and leaves on the rootstock.
3. Remove sprouts and set up supports
The management focus after grafting is to protect the scion and promote its sprouting. Rootstock buds sprouting below the graft union should be removed in time to reduce unnecessary nutrient consumption. After the new shoot matures, cut off the rootstock 1 cm above the graft union. New shoots have tender branches and large leaves and are very easy to break by wind, so supports should be inserted, and the new shoots should be tied firmly with film or other types of rope.
4. Fertilizer and water management
After the spring shoots mature, apply thin fertilizer frequently. Dig trenches to apply fertilizer, and apply the fertilizer on the drip line of the original tree canopy to stimulate fine roots. In drought, irrigate in time, and in the rainy season, drain in time to prevent waterlogging. In addition, attention should also be paid to strengthening the prevention and control of pests and diseases. Aphids can be controlled by spraying dichlorvos, and leaf spot disease can be controlled with thiophanate-methyl.
