现阶段油茶产量不高不稳的主要原因之一,是缺肥少水。因为油茶生长的丘陵红壤地区,有机质很贫乏,含氮和磷比较少,特别是有效磷奇缺,据化验,红壤的PH4.8-6.2左右,土壤表层有机质含量为1.3733-5.9430％之间,氮在O.25-3.00PPm之间,磷在O.3-1.4PPm之间,钾在6-60PPm之间,镁在O.25-40PPm之间,所以红壤的特点是,酸度大、粘性重、土壤板结、贫瘠易干、容易流失。而油茶是一年四季花果不离枝,根系发达,吸肥
One of the main reasons for the low production of oil tea at this stage is lack of fat and less water. Because the growth of Camellia oleifera area, the organic matter is poor, less nitrogen and phosphorus, especially the lack of available phosphorus, according to laboratory tests, red soil PH4.8-6.2 or so, the soil organic matter content of 1.3733-5.9430% Nitrogen is between O.25-3.00 PPm, Phosphorus is between O.3-1.4 PPm, Potassium is between 6-60 PPm, Magnesium is between O.25-40 PPm, so red soil is characterized by large acidity, Heavy, soil compaction, easy to dry barren, easy to drain. The Camellia flowers are not branches throughout the year, developed roots, fat absorption
