我国江苏省北部,南起崇明,北至云台山,长550公里的沿海地区,为一盐土性的冲积平原。土壤盐分以NaCl为主。在该区垦植计划中,种植防风林及护田林网的规划,对保证作物高额而稳定的产量是具有肯定意义的。但由於土壤含可溶性盐分过多,同时地下水位过高,造林就不若一般地区那样简单易行了。盐地造林是一个综合性的问题。选择适宜树种,也是其中重要环节之一。我们於1953—1955年,用盆栽方法,在人工加盐土壤中进行了播种、苗木移栽、扦插等试验,测定了23种林
China’s northern part of Jiangsu Province, Chongming from the south, north to Yuntaishan, 550 km long coastal area, is a saline alluvial plain. Soil salt is dominated by NaCl. In the reclamation plan of this area, planning for planting windbreaks and nursery shelterbelts is of positive significance for ensuring a high and stable yield of crops. However, because the soil contains too much soluble salt and the groundwater level is too high, afforestation is not as easy as in the general area. Salt afforestation is a comprehensive issue. Select suitable species, but also one of the important aspects. In 1953-1955, we planted potted plants in artificial salt-treated soils, transplanting seedlings, and cutting experiments. Twenty-three species of forest
