巴西橡胶树(Hevea brasiliensis.)是热带雨林树种,原产南美洲巴西亚马逊河流域,原产地的自然条件具有温度高而温差小,湿度大而静风,雨量充沛而雨日均匀的特点。在长期的适应过程中巴西橡胶树形成喜高温高湿,怕低温干旱和强风的习性。 福建南部干湿季明显,一般年份雨季多集中在5—9月,而10月至次年2月属干季。冬季气温较低,温差较大。虽然生境条件对巴西橡胶树的生长和产胶量的影响是综合的作用,但在福建地区水热条件是影响生长和产胶量的主要因素。
Hevea brasiliensis is a tropical rainforest tree species, native to South America, Brazil and Amazon, natural conditions of origin with high temperature and small temperature difference, humidity and quiet wind, abundant rainfall and rainy day characteristics. In the long-term adaptation to the process of adapting to a high temperature and high humidity, the rubber tree is afraid of hypothermia and strong wind habit. Wet and dry season in southern Fujian obvious, the general year rainy season mostly concentrated in the May-September, and October to February next year is a dry season. Winter temperatures are lower, the temperature difference is larger. Although the impact of habitat conditions on the growth and yield of rubber tree in Brazil is a comprehensive effect, the hydrothermal conditions in Fujian are the main factors affecting the growth and yield of rubber.
