一、低产原因分析1.经营管理粗放。产区农民经济基础差,国家对油茶生产的投入相对有限,致使油茶林的管理长期处于粗放经营状态,很少进行深翻垦复和施肥,根系生长受阻,影响对水分、养分吸收,导致树枝衰弱,产量不高。2.稀密不均,林分结构不合理。多代同堂,株产差异大,各地 First, low yield analysis 1. extensive management. Due to the poor economic base of peasants in the producing areas, the state has relatively limited investment in the production of camellia, which has led to the long-term management of camellia forests with little land reclamation and fertilization. The growth of the root system is hindered, affecting the absorption of water and nutrients, Weak, yield is not high. 2. Uneven density, stand structure is not reasonable.
