近年来,在本省海涂新围垦地发展了大批温州蜜柑,但对它在海涂的生长结果习性尚缺乏系统的了解。因此,我们从1979～1983年进行了这方面的调查,以期在制订生产技术措施时提供依据,现将调查情况叙述如下: 一、调查方法 本调查在黄岩县三甲区甲北乡飞龙村、六甲村和三甲乡的三塘村桔组进行。土壤为海涂中粘土,结构差,pH值8.5～9.0,含盐量在0.2％左右,有机质含量在1％以内。地势平坦,地下水位高,根系分布浅,一般离地表40厘米以下很少见根;而且土壤返盐严 In recent years, a large number of Wenzhou mandarins have been developed in the new reclaimed land of Tuhai, but there is a lack of systematic understanding of the habit of its growth in the coastal waters. Therefore, we conducted a survey in this area from 1979 to 1983 with a view to providing the basis for the formulation of technical measures for production. The investigation is described as follows: I. Methodology of the Investigation The survey was conducted in Feilong Village and Jiajia Village, Jiabei District, Jia’an District, Huangyan County Village and the village of three village three orange village. Soil is clay in the sea, with poor structure, pH 8.5 ~ 9.0, salt content of about 0.2%, organic matter content of less than 1%. Flat terrain, high groundwater level, shallow root distribution, generally less than 40 cm from the surface of the ground rare roots; and the soil salt back Yan
