Seedling selection standards for greening projects
1. Arbor
(1) Deciduous trees: Deciduous trees will all fall off in autumn and winter or during the dry season when there is no water.
Excellent seedlings: refers to seedlings with high ornamental value that have been cultivated by technical means such as shaping, pruning, grafting or natural growth to form special shapes; or seedlings with a chest diameter of more than 16cm that meet the requirements of high-quality seedlings.
High-quality seedlings: refers to seedlings with a chest diameter of more than 10 cm and a diameter of 15 cm or less, pruned and cultivated for more than 4 growth cycles, with branches of more than 5 grades; or unpruned and dried, the original crown width is more than 2 m, and the main branches are evenly distributed in a spiral from bottom to top.
Standard seedlings: refers to seedlings with a chest diameter of more than 6 cm and less than 15 cm, pruned and dried for more than 2 growth cycles, with branches of more than 3 levels; or seedlings that are not pruned and dried, with a native crown width of more than 1.5 m, the main branch is layered by more than 3 layers, and the distance between layers is uniform.
(2) Evergreen trees: Evergreen trees have evergreen properties, that is, green leaves all year round, this tree has green new leaves grow every year, and some fall off, because the green leaves will continue to renew, so the trees are green leaves all year round.
Excellent seedlings: refers to seedlings with high ornamental value with special shapes formed through shaping, pruning, grafting and other cultivation techniques or natural growth; or high-quality seedlings with a height of more than 5m.
High-quality seedlings: pine seedlings with dense crown shape, crown diameter and seedling height ratio greater than 3/4, uniform distribution of layer spacing, and interlayer distance accounting for about 5% of the natural height of the whole tree, or cypress seedlings with a crown diameter to seedling height ratio greater than 1/3.
Standard seedlings: refers to pine seedlings with compact and full crown shape, the ratio of crown diameter to seedling height is greater than 1/2, and the layer spacing is evenly distributed; or cypress seedlings with a crown diameter to seedling height ratio greater than 1/4.
2. Shrubs
The height of the shrub does not exceed 5 meters, and from near the ground, it begins to grow horizontal branches, all of which are perennial, generally broad-leaved plants, but also some coniferous plants.
Bulbous shrubs: full crown of the ball, no partial crown phenomenon; soil ball integrity; even branching; no diseases and insect pests and obvious scars and scars; smooth root incisions, no splitting, pulling, tearing phenomenon; flourishing branches and leaves, no obvious dead leaves.
Single-pole shrubs with branches less than 1 meter: the overall crown is full and there is no partial crown phenomenon; there are more than 3 secondary branches, the branches are uniform, and there are no diseases and insects and dead branches; the branches and leaves are flourishing, and there is no obvious dead leaves.
Clumped shrubs: the overall crown is full, without partial crown phenomenon; no less than 3 trunks, no diseases and insects dead branches; branches and leaves are flourishing, no obvious dead leaves.
3. Ground cover seedlings
Ground cover refers to the plant species that are tightly packed and low to cover the ground to form a certain garden cover landscape. Most of these ground cover plants grow low, expandable, and have a control height of 30 to 50 cm or slightly taller.
Ordinary ground cover: more than two years of cage goods should be selected, the branches should not be less than 3 to 4, the plant shape is full, the leaf clusters are robust, the tillers are dense, the color is bright, and the specifications meet the design requirements.
Flowers: Select container seedlings with initial flowering stage, full plant type and robust growth, and fill the pots with seedlings.
Root flowers: The root system must be intact and free of rot and deterioration.
Bulb flowers: The rhizomes are strong and undamaged, and the young shoots are full.
4. Lawn
The choice of lawn needs to be combined with the purpose of greening, lawn has ornamental, sports, and for slope greening, generally choose a suitable variety for planting. For example, ornamental lawns should choose varieties with dense growth, consistent height and long green time; sports lawns should choose trampling-resistant varieties; and the lawn used for slope greening must be adaptable.
Lawn has a warm season type and a cold season type, the choice of lawn varieties should also be adapted to local conditions, according to the local climatic conditions to choose suitable varieties for planting. (Flower and Wood Network)
