沙地海岸松造林实验及幼林生长调查探讨P.pinaster afforestation experiment and investigation of young growth 摘要:(摘要内容经过系统自动伪原创处理以避免复制,下载原文正常,内容请直接查看目录。) 本文对海岸松(Pinus pinaster Ait。)幼林的造林技巧、抗寒性、分歧氮肥处置对其幼林发展的作用停止了研究,西语论文题目,经由年夜量试验查询拜访,初步海岸松在中国沿海地域造林实验胜利。在山东沿海地域摸索出合适海岸松幼林发展的情况因子,并同时对海岸松造林技巧停止了试验研究。研究得出以下结论:(1)经由过程海岸松造林实验得出最合适海岸松幼林发展的前提是配比土(草炭土:蛭石:珍珠岩的设置装备摆设比例为4∶1∶1)、混交林造林,海岸松在海岸带上造林高发展与基径发展明显高于通俗造林地造林,然则存活率明显低于其他情况前提造林。(2)海岸松幼林法国种源的高发展明显高于西班牙种源(P<0。05)。混交林造林的法国种源海岸松幼林高和基径发展明显高于纯林造林的法国种源海岸松幼林(P<0。05),且造林后混交林的成活率明显高于纯林(P<0。05)。(3)海岸松具有较强的抗寒性,海岸松幼林法国种源纯林的抗寒性强于其西班牙种源纯林的抗寒性。海岸松法国种源混交林与其纯林比拟,未受冻害的植株数目差别不明显,西语论文,遭到稍微冻害的植株高于其纯林,但二者的的绿叶绝对电导率差别不明显。(4)氮肥处置对海岸松幼林发展起到明显感化,经由高氮量肥处置后海岸松幼林发展明显高于经由低氮肥处置的海岸松幼林,同时低氮肥处置下,法国种源海岸松幼林发展明显高于西班牙种源海岸松幼林;然则在高氮量肥处置下,法国种源海岸松幼林与西班牙种源海岸松幼林发展差别不明显(P>0。05)。 Abstract: This paper is on the coast pine (pinaster Ait Pinus. ) effects of young forest afforestation techniques, cold resistance, different nitrogen disposal to the development of the young was studied, and the through a large amount of experimental investigation, preliminary Pinus pinaster in China's coastal regions afforestation experiment in victory. Coastal areas in Shandong worked out appropriate coastal pine forest development factor, and at the same time on coastal Pine Afforestation Techniques research trials. Study reaches the following conclusions: (1) through coastal Pine Afforestation experiments, it is found that the most appropriate coastal pine the premise of plantation development proportion soil (peat: vermiculite: Perlite furnishings and equipment to set the proportion of 4: 1: 1), mixed forest, Pinus pinaster in coastal belt afforestation high development and base diameter development was significantly higher than that of common afforestation afforestation. However, the survival rate was significantly lower than the other conditions of the afforestation. (2) the high development of coastal Pine Provenances was higher than that of the French Spanish provenances (P < 0. 05). Mixed forest forestation of French provenance coastal pine forest and base diameter development was significantly higher than that of pure forest of French coastal resources Song Youlin (P < 0. 05, and the survival rate of the mixed forest was significantly higher than that of the pure forest (P < 0). 05). (3) Pinus pinaster with strong cold resistance, Pinus pinaster young French provenances of pure forest of strong cold resistance to cold resistance of the Spanish provenances of pure forest. Pinus pinaster French source mixed forest and pure forest compared to without freezing the number of plants did not differ significantly, was slightly freezing injury of plant was higher than the pure forest, but the two leaves absolute conductivity difference is not obvious. (4) nitrogen disposal of coastal pine forest development up to significant effect. Through high nitrogen fertilizer after the disposal of coastal pine forest development was significantly higher than that of low nitrogen disposal of coast via pine plantations, also under low N treatment, coast of France provenance pine forest development was significantly higher than that of the Spanish Provenances Coast pine plantations; however in high nitrogen fertilizer disposal, coast of France provenance pine plantation and Spanish coastal resources pine plantation development did not differ significantly (P > 0. 05). 目录: 摘要 4-5 ABSTRACT 5-6 1 引言 9-21 1.1 国内沿海防护林近况 9-13 1.2 引种驯化概况 13-14 1.3 我国林木引种的发展 14-16 1.4 松属特征 16 1.5 海岸松特征 16-17 1.6 海岸松探讨状况 17-18 1.7 国内外海岸松探讨近况 18-20 1.8 海岸松的先进性以及推广前景 20-21 2 探讨目的、内容和措施 21-29 2.1 探讨的目的和科学问题 21 2.2 试验地点 21-23 2.3 探讨内容 23-24 2.4 探讨措施 24-28 2.5 数据略论和技术路线特点 28-29 3 海岸松造林试验 29-35 3.1 前言 29 3.2 结果与略论 29-33 3.3 小结与讨论 33-35 4 海岸松抗寒性探讨 35-38 4.1 前言 35 4.2 结果与略论 35-36 4.3 小结 36-38 5 不同氮肥处理对海岸松幼林生长的作用 38-42 5.1 前言 38 5.2 结果与略论 38-40 5.3 小结 40-42 6 结论 42-44 6.1 结论 42 6.2 讨论 42-44 参考文献 44-49 个人简介 49-50 导师简介 50-51 致谢 51 |
