摘要
Abstract
In recent years, a large - area of Ligustrum japonicum Howardii in both sides of Xihuan road and provincial road No. 331 of Yancheng city in Jiangsu province withered, and the dead rate of plants in the heavy damage land exceeded 80%. In order to find out the reasons of inducing the death of plants, this paper systematically compared and analyzed some environmental factors in heavy damage land and normal land, such as soil nutrition, soil physicochemical property, chemical property of irrigation water and ground water. The results showed that the main reason of inducing the death was too high salinity of irrigation water when the plants were transplanted. Through single factor test, it was found that the survival rate of plants could be significantly increased by the following measures: removing mortar shell, building the sun net for shade, appropriately shallow planting, and timely weeding and loosing the soil after rainfall. The survival rate of plants could be further increased by irrigating 100 - 500 mg/L FeSO4 solution when they were transplanted.关键词
