保护地栽培土壤锰毒的矫正

模拟玻璃温室、塑料大棚硝酸钙盐积累状况,用辣椒进行盆栽试验,研究土壤锰释放规律及植物锰中毒的矫正方法。试验结果表明：添加硅、镁、铁肥和石灰,对矫正辣椒锰中毒都有一定的效果,而以施石灰法最好。

Study on the Correction of Manganese Toxicity in Protected Cultivation Soil

Soil Secondary Salinization was main adverse physiolgical factor of vegetable growth in protected cultivation,and salt induced manganese solublization could cause Mn toxicity in acid soil and the soil with high content of native Mn. Calcium nitrate salt accumulation of soil in protected cultivation induced Mn release.The authors investigated the corrective methods of Mn toxicity in soil for pepper growth in a pot experiment.The result showed:the application of lime ,silica fertilizer,magnesium fertilizer,and iron fertilizer could alleviate Mn toxicity in pepper growth,and the application of lime was the best method of the alleviation of Mn toxicity.
