根据我们在无锡蠡园乡三个村的土壤调查结果,不少菜地土壤pH值在4.5～5.2之间,致使蔬菜单产总产下降.大白菜等对土壤酸度反应较敏感,土壤酸度偏高,不但生长受抑,且诱发病害,减产尤为显著.据报道,石灰对酸化菜上可以改良.但各地情况不一,用量各异,较难借鉴.现选择蠡园乡东风村酸化菜地,进行石灰不同用量试验,以探明石灰对大白菜的增产效果和改良太湖地区冲积土酸化菜地的适宜用量. According to our soil survey results in the three villages of Xinyuan Township in Wuxi City, many vegetable soils have pH values ​​ranging from 4.5 to 5.2, resulting in a decrease in total yield of vegetables per unit area. Chinese cabbage is more sensitive to soil acidity and has a higher acidity , Not only growth inhibition, and induced disease, especially in the reduction of yield.It is reported that lime on acidified vegetables can be improved.But all over the different conditions, the amount of different, more difficult to learn.Currently choose Yeyuan Township, Dongfengcun acidification vegetables, Different amount of lime was used to test the effect of lime on Chinese cabbage yield and the appropriate amount of acidified vegetable garden in alluvial soil in Taihu Lake.
