Fast-growing tree seedling transplant
First, the first transplant. The first transplant was when the seedlings were grown to a diameter of about 1 cm through the sowing bed. Seedlings at this stage are still relatively short, and they are cultivated in dense plants. The purpose is to promote the rapid growth of seedlings.
1. Requirements for transplantation: (1) The transplant season is mainly in spring, supplemented by summer and autumn. (2) The bed size is 1.2-1.5 meters wide, the trail is 50 centimeters, and the seedbed is taken north-south. (3) The row spacing of the transplanted plants was 8080 cm row spacing and planted in double rows.
2. Requirements for transplantation methods: (1) Seedlings should be organized closely from the time of digging, transportation, and planting, and the root system should be as short as possible. (2) Seedlings should be graded when transplanted, Grade A or Grade B seedlings should be used, and they should be planted strictly. They should not be mixed. (3) Seedlings require appropriate amount of original bed soil, and the main root should be cut before planting. The length of the main root is 15-20 cm, and the total lateral root is 15-20 cm. (4) The leaves of the upper part of the transplanted seedlings should be cut properly, but the top shoots must be preserved. (5) The planting depth should be slightly deeper than that of the original seedbed. (6) Immediately after planting, water is poured two or three times every 3-7 days.
Second, the second transplant. The second transplant was in the 4-5 cm diameter stage of seedlings. Although seedlings have reached the basic requirements for urban afforestation seedlings, the adoption of continuous planting and cultivation will allow them to obtain large-scale, high-quality green seedlings with certain dry heights and crowns.
1. Requirements for transplantation: (1) The transplant season is mainly in spring, supplemented by summer and autumn. (2) The bed size is 1.2-1.5 meters wide, the trail is 50 centimeters, and the seedbed is taken north-south. (3) The transplant spacing was 110-12080-90 cm, and the two rows of plants were planted in a staggered arrangement.
(2) Requirements for transplanting seedlings: (1) Try to bring soil ball when digging, and prune the wound roots, leaving a total lateral root of 30-40 cm. (2) Broad-leaved tree species are pruned at this time, and the seedling height is 2.8-3.0 meters. (3) The transplanted seedlings to be excavated should be graded and grade A or grade B seedlings should be selected and transplanted strictly.
3. Requirements for transplantation methods: (1) The transplantation process should be organized closely to minimize the exposure time of the seedling root system and improve the survival rate of the transplant. (2) The planting depth of seedlings should be 5-10cm deeper than the original ground, and the root plate should not be exposed when planting. (3) Transplantation work should meet the requirements of orderliness and cleanliness. After transplanting, seedlings should be planted in rows and columns, neatly arranged, and the seedlings should be clean and tidy. (4) Immediately after planting, the root water is poured, and then water is poured two or three times every 3-7 days.
Slow seedling transplant
First, the first transplant. The first transplant was performed after 1 year of seedling cultivation.
1. Requirements for transplantation: (1) The transplant season is mainly in spring, supplemented by summer and autumn. (2) The bed size is 1.2-1.5 meters wide, the trail is 50 centimeters, and the seedbed is taken north-south. (3) The transplant spacing is 20-4030 cm.
2. Requirements for transplantation methods: (1) Seedlings should be organized closely from the time of digging, transportation, and planting, and the root system should be as short as possible. (2) Seedlings should be graded when transplanted, Grade A or Grade B seedlings should be used, and they should be planted strictly. (3) Seedlings require appropriate amount of original bed soil, cut the main root before planting, and leave the main root length 15-20 cm. (4) transplanted seedlings should be properly cut less leaves to reduce transpiration. (5) The planting depth should be slightly deeper than that of the original seedbed. (6) Immediately after planting, water is poured two or three times every 3-7 days.
Second, second and third transplants. The second and third transplants are basically the same as the transplants of fast-growing species.
