马鞍形的产胶模式是河口垦区橡胶生产的一般规律,它被橡胶科研和生产技术人员所公认和运用。形成这一规律的原因,尚在探讨中。有的认为与胶树开花、结果等发育期有关;有的认为与胶树枝叶生长等物侯期有关;有的即从生理生化的角度去分析,认为与胶树生产的物质分配和转化有关;有的虽然也与气侯因素联系起来分析,但多偏重于从光合作用产物的多寡方面去考虑。一九八一年橡胶产量的
Saddle-shaped plastic production model is the general rule of rubber production in estuarine reclamation area. It is recognized and applied by rubber research and production technicians.
