Pruning of welcoming pine: The normal leaf length of welcoming pine is 8 ~ 18 cm, and the needles can be controlled at about 6 ~ 8 cm by measures such as bud picking and water conservation, so bud picking is the main method. Every spring, the new buds of welcome pine are lengthened, and the terminal buds are removed about 1b2 before the needles germinate, or all the winter buds can be erased. The terminal bud can be removed according to the needs of the whole stump modeling, with more strong branches and less or no weak branches. In addition, in winter, trees can prune branches and leaves that affect the graceful posture of trees.

Turnover of welcome pine: it is usually done once every 3-4 years, but small shallow pots can also be turned once every 2 years and large deep pots once every 5 years.

Dendrolimus punctatus and Dendrolimus punctatus can be sprayed with 50% dichlorvos emulsion 1000 ~ 1500 times. Dendrolimus punctatus can be sprayed with 25% acephate EC or 50% cartap 300 times. Pine sawflies can be controlled by spraying trichlorfon or marathon 1000 ~ 1500 times.
