Alpine region Introducing test Robinia pseudoacacia
18 films. View from the survival rate of seedlings, 1 year survival rate of seedlings survival rate of 95,2 years old seedlings is lower than 1 year old seedlings. Overall plant situation, the 1 year old Black Locust seedlings at the first cell has a strong adaptability, relatively poor 2-year seedlings.

(3) seedling growth in cell No. 3 Table 43 Growth of seedlings Statistical Area observed average budding rate () the average number of leaf expansion (film) survival rate () can be seen from Table 4. In the same observation time, 3 quarters of 1 year old Black Locust seedlings sprouting leaf expansion rate and the relative number of seedlings to 2 years high. to 5 months, late, 1 year old seedlings, the average budding rate of 78, higher than the 2-year seedlings of 25. The average number of leaves show more than 2 years old seedlings of about 9,[link widoczny dla zalogowanych], the survival rate higher than 2 years old seedlings of 25 or more. from Table 2,[link widoczny dla zalogowanych], Table 3, Table 4, the budding rate of tetraploid black locust, leaf number and survival rate of the overall cultural situation observed in the sunshine, soil moisture under the same conditions. tetraploid black locust seedlings of different ages different growth conditions. seedling adaptability 1 year to 2 years old seedlings of the adapting ability. budding and leaf expansion are earlier than 2 years old seedlings, and the budding rate, number of leaves show more seedling vigor is good, leafy 3. .2 different site conditions on growth of Robinia pseudoacacia seedlings cultivated area under different site conditions. investigated during the same period 1 year and 2 years old Black Locust seedlings sprouting rate, leaf condition and survival. results in Table 5. Table 51,2 seedling growth conditions in Tertiary Students observe the average budding rate () the average number of leaf expansion (film) survival rate () can be seen from Table 5, the same species of black locust, in a different district , growth conditions are different. 1 year old Black Locust seedlings average budding rate, average number and leaf area are the No. 1 highest, 3 the lowest. From the point of view of plant physiology, mainly due to three quarters of sunshine hours and caused by differences in soil moisture. In 1, the region above the sunshine time of up to 8h. adequate soil moisture. loose soil, whether it is 1 year old seedlings, or seedlings for 2 years. growing well, lush foliage. lamina large, germination rate and survival rate. especially the 1 year survival rate of seedlings District No. 1 of 95 or more. 2, 1, soil moisture and the same area. As Crown shade garden around the protection. the No. 2 cell was significantly shorter sunshine hours,[link widoczny dla zalogowanych], resulting in Germination Late than 1 6 ~ 9d, and growing weaker,[link widoczny dla zalogowanych], sparse foliage. 3 zone. sunshine than 1 zone, 2 zone is short, and the soil humidity. sunshine duration shortening and higher soil moisture content, to a certain extent, affected the Black Locust seedlings photosynthesis and root respiration, resulting in cell No. 3 Germination of Black Locust seedlings and leaf expansion delayed. growing weakest. 4 Summary ( 1) introduction and cultivation of the whole situation, 1 year old Black Locust seedlings seedling survival rate of 95,2 years, the survival rate was 76, successful introduction and cultivation. (2) compared with normal locust, leaf size Fourfold is the common locust leaves more than 2 times, dark green leaves. mesophyll hypertrophy, suitable altitude of 2970m in the alpine region growing, and winter survival rate of 1O0. (3) introduction and cultivation from the situation, Black Locust and light for the hi plants. transplanting survival after the strict requirements for water, forest fast, soil and water conservation. sand-fixing, a good tree Forest. as Woody forage, can adapt to almost 3000m above sea level in Tibet's environmental conditions. as resolve agricultural and pastoral areas of Tibet in winter animal feed shortage of great significance.
