Spring: ① gradually remove the cold-proof facilities and objects, and carry out irrigation and fertilization to create suitable water and fertilizer conditions for the germination and growth of trees; ② Replanting the missing plants; (3) budding and cutting the original and newly planted trees; (4) the wind damaged trees are righted, the roots are cultivated into steamed bread, and the pillars are erected; ⑤ Do pest control work well in spring, and start comprehensive control spraying in March; ⑥ Prepare for flood control in rainy season.
Summer: ① pay close attention to watering and drought resistance, and strengthen drainage and flood control when there is too much rain; (2) Prevention and control of diseases and insect pests, especially leaf diseases and insect pests; (3) Pruning should be as light as possible during the growth period, mainly to control the occurrence and growth of competitive branches, internal branches, upright branches and long branches, so as to concentrate nutrition for the vigorous growth of backbone branches.
Autumn: ① Continue to do a good job of drought relief and drainage in the later period, irrigate during drought, and drain accumulated water in time during waterlogging; ② Planting trees in autumn; (3) prevention and control of pests and diseases, timely spraying; (4) Retting vegetables to prepare for fertilization in winter.
Winter: ① Plastic pruning in winter. The pruning of young trees is mainly plastic pruning. For foliage trees, the purpose is to control the growth of lateral branches, promote the growth of main branches, prune branches of diseases and insect pests, clustered branches, dead branches and vines, and keep the tree beautiful; ② Open annular ditch and apply winter fertilizer to ensure the growth in the coming year; (3) Do a good job in cold protection, and wrap straw rope above the base of the trunk of the newly planted non-cold-resistant tree species to keep out the cold; (4) control pests and diseases, and eliminate overwintering insect packs, cocoons and larvae; ⑤ Painting: Apply lime liquid (slurry) at the position 1.2 ~ 1.5m above the base of the well-growing trunk, and paint with salt to make the coating uniform and the upper edge smooth.
2。 Planting modeling colored plants
Trim and reshape in time, keep it neat and beautiful, trim messy branches and vines to make the lines straight or in a certain shape, clean up the scene in time, grasp the insect situation in time and take preventive measures. Apply organic fertilizer in winter and spring, and the organic fertilizer will enter the soil by digging the soil and combining drought resistance.
Step 3 nip the bud
Erase the adventitious buds in time, all the buds below the bifurcation of the trunk are erased, and the buds above the bifurcation point are reasonably reserved according to the plastic requirements; Clean up the budding parts in time.
4. Drought tolerance
Grasp the drought, timely drought, do not appear the phenomenon of leaf atrophy, dry branches, must be watered to support buds, can be combined with fertilization.
Step 5 transplant
Dig a pit according to the specification requirements, remove all chores, the depth meets the requirements, and the upper and lower calibers are consistent. Prune before planting, cut off the branches and roots that have been broken during excavation and transportation, and cut off the leaves of evergreen trees, which must be planted, compacted, protected, wrapped with straw ropes and watered.
6. Hygiene
Clear the garbage and all sundries (including objects hanging from trees) in the green space.
