When will the evergreen tree Luohan pine be grafted? What are the grafting methods?

Luohan pine alias Taxodium, Luohan pine family, is an evergreen coniferous tree, distributed in many provinces of China, cultivated in the garden as an ornamental tree. So do you know when Luo Han Song will be grafted? Are there any grafting methods? According to the data, Luohansong is generally about ten days before the beginning of spring, and it can be grafted at the end of February or early March, with a high success rate.

Grafting method of Luohansong

1. Tools and materials to be prepared before grafting

Single-sided blade, because it is sharper and thinner than grafting knife; plastic fresh-keeping bag, used for bagging and moisturizing of scion and grafting site; medical sterilized alcohol, used for disinfection and sterilization of grafting blade; nylon rope, used for binding scion.

two。 Twig grafting method

The 2-year-old potted large-leaf Luohan pine was used as the rootstock, and the rootstock was pruned properly before grafting, cutting off the opposite branches, head-on branches and other branches that were not conducive to modeling, and then the tender shoots of Siraitia grosvenorii were selected, and 3-4 cm were used as scions. The long part can be reserved for post-use. The cutting method of scion is the same as conventional grafting. Special attention should be paid to aligning the scion with the cambium of the rootstock, and if other operations and post-grafting management are properly managed with other grafting methods, the survival rate can reach about 95%.

3. High branch grafting

The rootstock uses the larger large-leaved Siraitia grossedentata, which is grafted with the cutting method where the branches are needed. The specific operation is the same as the general splicing method. However, the survival rate of this grafting method is relatively low, so multiple scions need to be grafted around the same branch site.

4. Abdominal connection method

Using 2-year-old or 3-year-old Pinus elliottii as rootstock, the specific operation and management are the same as the five-needle pine grafting method. If this grafting method is managed properly, the survival rate can reach about 90%. No matter which of the above methods are used for grafting, it is necessary to bag and moisturize the scion. Although the grafting of Pinus elliottii can be carried out all the year round, if it is carried out in the hot summer and cold winter seasons, extra care is needed in management to ensure the survival rate.

5. Pest control

Spray with 50% methyl topiramate wettable powder 500 times. Pests are harmful to shell insects, red spiders and coir moths, which can be sprayed with 1500 times omethoate EC.

Note: when the grafting technique is not skilled, it is better to use 2-3-year-old Pinus elliottii for abdominal grafting, and then shoot grafting or shoot high grafting from April to July, which is beneficial to improve the survival rate of grafting.
