1983—1984年在浙江省棉医,海相沉秩物发育、呈偏碱性的土壤;以及红壤发育的微酸性土壤上,进行棉花锰腮试验结果表明,用0.5％MnSO_4漫种和叶面喷施0.2％MnSO_4 3—4次的皮棉增产效果最好,两年中4个试验点的皮棉产量均达到极显著和显著水平。土壤施MnSO_4 4和2斤/亩的次之。另外,施用MnSO_4的棉叶内叶绿素合成和净光台产物增加,糖和氮化合物的合成和转化力口速,
1983-1984 in cotton medicine in Zhejiang Province, the sea sediments are alkaline, alkaline soil; and red soil development of slightly acidic soil, the results of the cotton manganese gills showed that 0.5% MnSO_4 diffuse and foliar Lint yield of 0.2% MnSO_4 3-4 times was the best, and lint yield reached the most significant and significant level at 4 test points in two years. Soil facilities MnSO 4 and 2 pounds / mu second. In addition, the application of MnSO_4 cotton leaf chlorophyll synthesis and net Taiwan products increased sugar and nitrogen compounds synthesis and transformation speed mouth mouth,
