试验地设在温州市洞头县黄岙柑桔场,系新围垦未用的海岛海涂。据试验前1986年进行的土壤理化性状分析,20～40cm土层含盐量0.28％,pH值8.6,有机质0.97％,容重1.42g/cm~3。试材为早熟温州蜜柑,行株距2米×1.7米,试验面积2.7hm~2,
Experimentally located in Dongtou County, Wenzhou City, Huang Huang citrus fields, the new reclamation unused island sea. According to the analysis of soil physical and chemical properties before 1986, the salt content in 20 ~ 40cm soil layer was 0.28%, pH value was 8.6, organic matter was 0.97% and bulk density was 1.42g / cm ~ 3. Test materials for early maturing Satsuma, line spacing 2 m × 1.7 m, the test area of 2.7hm ~ 2,
