一、油茶大小年产生的原因油茶成林,每年都要抽梢换叶,老果未摘新蕾已生,花果不离枝,周而复始,循环不息。因此,要求地下具有足够的水分和养分供应;地上要有充分的光能利用,才能确保高产稳产。但是,在实际情况中,往往由于外界环境条件的变异,响影到油茶产量的不稳定,甚 First, the size of the annual output of camellia Camellia into forest, every year to shoot for leaf replacement, the old fruit has not picked Xinlei has been born, flowers are not branches, go round and round, endless cycle. Therefore, it is required that sufficient underground water and nutrient supply be provided; sufficient light energy is used on the ground to ensure high and stable yield. However, in reality, often due to the variation of external environmental conditions, the shadow of the unstable yield of Camellia, and even
