橡胶树的生产力由光能、热能、水份、土壤资源所构成。我场处于北纬21°36′～21°38′之间,属轻寒轻风区。太阳总辐射热125～130卡/平方厘米·年,年平均气温22～23℃,相对湿度73～80％,年雨量2000～2500毫米。基本能满足橡胶生长所需要的光、热、水份条件,是湛江北部地区发展橡胶较理想的地区之一,但橡胶增粗不快,产量不高,按种后17年(1980年)的PB86、
Rubber tree productivity from light, heat, water, soil resources. My field is between latitude 21 ° 36 ’~ 21 ° 38’, which is a cold and light breeze area. The total solar radiation heat 125 ~ 130 cards / cm 2 years, the annual average temperature of 22 ~ 23 ℃, relative humidity 73 ~ 80%, annual rainfall 2000 ~ 2500 mm. Basically meet the rubber growth needs light, heat, water conditions, is the development of northern rubber Zhanjiang more ideal one of the regions, but the rubber thickening unpleasant, the yield is not high, according to the species 17 years (1980) PB86 ,
