| 中文摘要: |
| 以初植腾冲红花油茶林为试材，测定稻草、薄膜和遮阳网3种覆盖方式下腾冲红花油茶从定植之日起到次年年底地径和树高生长量及当年抽梢长度3个生长量指标，分析不同处理间的生长量差异性。结果表明，3种覆盖措施均能有效促进腾冲红花油茶地径、树高和抽梢长度增长，其中对树高和抽梢长度的促进作用最为明显。与对照比较，稻草覆盖对腾冲红花油茶的生长促进作用不显著，薄膜覆盖和遮阳网覆盖对地径生长作用差异显著，对树高和抽梢长度的生长作用差异极显著。建议在腾冲红花油茶定植后3年内，尽量采取覆盖措施，且最好用遮阳网覆盖或薄膜和遮阳网综合覆盖。 |
| 英文摘要: |
| Taking the newly planted Camellia reticulata forest as the test material, the three growth indexes of ground diameter, tree height and shoot length of Camellia reticulata from the date of planting to the end of the next year under three mulching measures of straw, film and shading net were measured, and the differences of growth among different treatments were analyzed. The results showed that the three mulching measures could effectively promote the growth of ground diameter, tree height and shoot length of Camellia reticulata, among which the promotion effect on tree height and shoot length was the most obvious. Compared with the control, the effect difference of straw mulching on the growth of Camellia reticulata was not significant, while the effect difference of film mulching and shading net mulching was significant on the growth of ground diameter, and extremely significant on the growth of tree height and shoot length. This paper suggested that mulching measures should be taken within 3 years after the planting of Camellia reticulata, and the shading net mulching or the comprehensive mulching of film and shading net were the best. |
