(I) quality inspection of integrally-shaped nursery stock

And (4) taking out the nursery when all the joints of the whole nursery stock are completely healed or the trunk is thickened to meet the requirement after the trunk section is grafted and modeled. Before the seedlings are out of the nursery, the quality investigation of the whole seedlings of each grafting shape is firstly carried out. Accurately mastering the name, modeling style, quantity, cultural meaning, interface healing condition, color type, specification, root growth, crown structure, tree trunk artistic forming quality and the like of each modeling integral nursery stock so as to make a outplanting plan of qualified nursery stocks. This work requires a high degree of care.

(II) outplanting and managing of nursery stock

Formally lifting seedlings: seedlings which have reached the specifications of outplants or which need to be transplanted for further cultivation of big seedlings are taken. The work is one of the important links of the seedling production, and directly influences the transplanting of the seedlings, the afforestation survival rate and the greening effect.

Whether fallen leaves or evergreen tree species, seedlings should in principle be lifted during the resting period. Therefore, the seedlings are early to be lifted in spring, and are preferably planted along with the seedlings.

Taking out seedlings with soil balls: most evergreen broad-leaved trees and few deciduous broad-leaved trees and coniferous trees have undeveloped root systems, few fibrous roots, weak rooting capability and large transpiration amount, so soil balls are required to be carried. The size of the soil ball varies depending on the size of the seedling, the difficulty of survival of the tree species, the distribution of the root system, the soil conditions and the transport conditions. Generally, the radius of the soil ball is about 5 to 10 times of the diameter of the rhizome, and the height is about 2/3 times of the diameter of the soil ball. The branches and leaves of the big seedlings are bound by ropes to reduce the volume, so that the big seedlings are convenient to operate and transport; the seedling lifting depth determines the length and the number of the root system of the seedling, the seedling lifting depth of the needle leaf seedling and the broad leaf seedling is 20 cm-30 cm, and the seedling lifting depth of the cutting seedling is 25 cm-30 cm; meanwhile, attention should be paid to the fact that seedlings are not lifted when strong wind blows, otherwise, the seedlings lose too much water, and the survival rate is reduced; if the seedlings are in a dry nursery, water is added 2 to 3 days before the seedlings are lifted to moisten the soil so as to reduce the damage to the root systems during the seedling lifting.

Packing and transporting

In order to prevent the root system from drying and prevent the quality of the seedlings from being reduced in the transportation process, the seedlings are packaged, and the roots and leaves of the seedlings are prevented from being exposed to the sun or being blown by wind for a long time. The packaging work should be carried out at the lee and sprout-preventing place, and the seedling crown of the evergreen tree species should be exposed to prevent mildew and rot. When the nursery stock is transported, the nursery stock is covered with rice straw, gunny bags, straw mats and other objects by sprinkling water, the humidity and temperature between branches and leaves are checked frequently, and ventilation and sprinkling are carried out according to the temperature and humidity conditions.

Temporary planting before planting

A large number of seedlings which cannot be timely transported away after seedling emergence or are not planted need to be temporarily planted. The temporary planting land needs to select a place with good drainage and facing the sun in the lee, the temporary planting depth of the seeding is 30-40 cm, and the trench wall facing the wind is made into an inclined wall of 45 degrees. When temporary planting is carried out for a long time, deep burying, single-row treading, shading by using a mat, a shading net and the like and temperature reduction are required.

In a word, the nursery stock is a living plant, the growth requirement of the nursery stock is timely and properly met in the outplanting process, the implementation of technical measures in each link is ensured, and the improvement of the planting survival rate of the nursery stock can be ensured.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
