浙江南部的滨海盐土,质地粘重,pH8.4左右,一经围垦蓄淡,3—5年后,就可逐步改成良田.1.围塘:由于土质粘重,堤塘初期沉陷现象严重,因此须采用分期逐步围塘办法,利用农闲逐步加高.堤塘高1.5—3米,堤脚宽约5—12米,沿堤留20米空地,种植护堤林;空地内绿再开一条排水主沟.堤上种草,以保护堤塘,每年秋潮前,进行挑土培修一次,以护堤塘.
Coastal saline soil in southern Zhejiang, sticky texture, pH8.4 or so, once the reclamation of light, 3-5 years later, can be gradually transformed into fertile fields .1 Wai pond: due to soil sticky weight, ditang initial subsidence phenomenon is serious, Therefore, it is necessary to adopt a phased approach of enclosing the ponds to gradually increase the use of agricultural leisure. The embankments are 1.5-3 meters high and the embankments are 5-12 meters wide. Drainage main ditch embankment grass, in order to protect the dike, autumn tide before each year, picking soil training time to protect the dike pond.
