Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seedling cultivation, in particular to a transplanting seedling afforestation method. BACKGROUND

[0002] Most of the artificial forests are transplanted, however, for the psammophyte, it is difficult to survive after transplanting, therefore, improving the survival rate of seedling transplanting has been the goal pursued by the skilled in the art.

[0003] On the other hand, in order to improve the survival rate of transplanting, the skilled in the art usually adopts the transplanting mode of taking soil ball and container seedling; however, in the process of transportation, the soil ball of the seedling often breaks and cracks, in order to avoid this technical problem, the skilled in the art often winds the soil ball with grass rope, but the cost of the grass rope is too high, and it is difficult to operate, the cost is too high; at the same time, although these measures improve the survival rate of tree transplanting to a certain extent, there are still problems of long slow growth period and low survival rate of transplanting.

After the seedlings are in place, remove the bag or make more holes in the bottom and sides of the bag to allow the roots to pass through.

[0005] Furthermore, in step S4, 3-5 remaining roots are left for large seedlings, and 1-2 remaining roots are left for small seedlings.

[0006] Furthermore, in step S5, for small seedlings, the bag is inserted from the top to the bottom of the seedling through the cross hole, and the remaining root system is inserted into the bag. The bottom of the bag is cut and overlapped.

[0008] Furthermore, in step S5, one bag is inserted for each seedling, and multiple seedlings are treated.

[0009] Furthermore, the seedling substrate is mixed in the following proportions: sand: coal gangue powder: mudstone powder: dry branch and leaf powder = 1.5:1:1.5:0.45.

[0010] Furthermore, the method of bagging in step S5 is as follows: (1) Cut a cross hole at the position corresponding to the bag, or cut a slit on the side wall from the bottom of the bag. (2) Insert the bag from the top to the bottom of the seedling through the cross hole, or insert the bag into the bottom of the seedling through the slit. The remaining roots are left outside the cross hole or slit, and the remaining root system is inserted into the bag. The bottom of the bag is cut and overlapped, and the side wall is sutured. Figure 1 (3) Flatten the bottom of the pit.

[0011] Furthermore, in step S10, when the number of remaining roots is 1, do not cut the roots; when the number of remaining roots is 2-3, cut 1 remaining root; when the number of remaining roots is 4-5, cut 2 remaining roots.

[0032] Moreover, the large seedling is a seedling with a height of more than 1m or a tree crown larger than 0.6m.

[0033] Comparative examples 1-9 Comparative examples 1-9 and example 3 differ in the seedling substrate (Table 1).

[0034] Before transplanting, 100 seedlings from Examples 1-3 and Comparative Examples 1-9 were randomly selected. Before transplanting, the woven bags were removed, and each seedling was inspected to check whether the root ball was intact and whether there were any cracks, breaks, or looseness. The root ball integrity rate was calculated as follows: Root ball integrity rate = (Total number of root balls - Number of cracked, broken, or loose root balls) / Total number of root balls. At the same time, the seedling recovery time was recorded. The results are shown in Table 1.

[0035] Comparative Example 10 The difference between this comparative example and Example 3 is that step S5 (bagging) was not performed. In step S7 (filling), seedling substrate was used to fill the dug tree pit. Due to the inconvenience of later processing, step S10 (root pruning) was not performed, and transplanting was carried out directly in step S11.

[0036] Comparative Example 11 The difference between this comparative example and Example 3 is that when digging up seedlings in step S4, all the seedlings were dug up without leaving any roots. The Meizhi supply bag was directly placed over the roots and then filled with seedling substrate. In the later stage, there was no need to cut the roots in step S10.

[0037] One hundred seedlings were randomly selected at ratios of 10 and 11 respectively. The seedling recovery time was recorded. The seedling survival rate was recorded one month after transplanting. The results are shown in Table 1.

[0038] Table 1 Comparison of seedling survival rate and recovery time

[0039] As can be seen from Table 1, in this invention, after removing the woven bags, the soil ball integrity rate can reach 100%, the seedling survival rate is 99%, no seedling slow-growth phenomenon was observed, and the growth was equally vigorous after transplanting and before transplanting.

[0040] Due to the difference in seedling substrate compared to the present invention, the integrity of some soil balls in Comparative Examples 1-9 was affected, especially in Comparative Example 9, where all soil balls loosened and fell off after the woven bags were removed. The survival rate of seedlings in Comparative Examples 1-9 was also affected. After transplanting, the recovery period was relatively long, with the longest observed period being 38 days, and the growth of the seedlings was severely affected.

[0041] Comparative Examples 10 and 11, due to the absence of step S5 (bagging) and the failure to retain roots, showed a lower seedling survival rate compared to the present invention, with recovery periods of 42 and 32 days respectively, thus affecting seedling growth.
