胶园林网化改善了自然环境条件,有效地减轻胶树的风害,並提高其生长量和产量,是我国植胶事业具有独特的一项技术措施。但另一方面,位于防护林两侧的胶树,由于光、水、肥等因子的竞争,在一定范围内受到不同程度的影响,其影响范围也可称谓“林带胁地”。林带胁地的大小与林带网格面积成反相关关系。如一般以林段四周的边一行和边二行的胶树作为受影响的范围计,当林段面积为15亩时,边一行的植株约占林段内总株数的19～24,6,边二行占17～22％,两者累计占林段内近1/3～1/2的面积;如林段面积为30亩时,边一行占13～17％,边二行占
Rubber garden network to improve the natural environmental conditions, effectively reduce the gum tree wind damage, and increase their growth and yield, is a unique plastic plant in our country a technical measure. On the other hand, the gum trees on both sides of shelterbelt are affected to some extent by the competition of light, water and fertilizer and other factors, and their influence range can also be called “forest belt threatening.” The size of forest belt is inversely related to the net area of forest belt. For example, when the forest area covers an area of 15 mu, the trees on one bank account for 19 ~ 24,6 of the total number of trees in the forest section, The second and second rows account for 17-22% of the total area, both of which account for nearly 1/3 to 1/2 of the forest area. For example, when the forest area is 30 mu
