一、问题的提出油茶是我国南方广大地区重要的食用油料树,有着悠久的栽培历史。在福建山区栽培极为普遍,是福建主要的经济林木之一。但福建多山,地质复杂,同时还由于各地对油茶林土壤经营管理集约水平的差异,因而使得油茶最主要的经济指标——茶油的产量十分悬殊。1979——1981年间分别对栽培油茶较多地区的闽东的闽侯县桐口林场、福安县化蛟林场,闽北的福建林学院西芹教学林场、沙县官庄林场和闽中偏北的尤溪县经营林场等低山地区(海拔500米以下)油茶林土壤与产量进行调查分析。各调查地区选择不同的经营管理与油茶生长相对稳定的地方挖设土壤剖面并取土分析。首先,从表.1中可看出调查地区油茶产量差异非常大,不但各调查点内不同年份波动较
First, the issue put Camellia oil is an important edible oil trees in vast areas of southern China, has a long history of cultivation. Cultivation in mountainous areas of Fujian is extremely common and is one of the major economic trees in Fujian. However, mountainous Fujian, geological complex, but also because of the various parts of the oil palm forest soil management level of intensive differences, making the most important economic indicators of tea - tea oil production is very poor. From 1979 to 1981, we studied the effects of Tongkou forest farm in Minhou county, Fujian province, Jiao forest farm in Fujian province, Fujian province forestry celery teaching forest farm in North Fujian province, Guanzhuang forest farm in Shaxian county and north-central Fujian province Youxi County forest farms and other low mountain areas (500 meters above sea level) of Camellia oleifera soil and yield were investigated. In each survey area, different management and selection were chosen to dig the soil profile and take soil analysis where the growth of Camellia oleifera was relatively stable. First of all, it can be seen from Table 1 that the differences in the yield of Camellia in the survey area are very large. Not only the fluctuation in different years in each survey area is relatively
