不同地区风化煤对玉米发芽的影响

Effect of Weathered Coal in Different Regions on Corn Germination

通过选择5个不同地区的风化煤,设置0.5%和1.0%2种使用浓度,进行玉米发芽试验。结果表明:不同地区风化煤由于质量差异较大,对玉米芽长、根长及干物重的影响不同。整体来看,以处理3(宁夏石嘴山)、处理4(山西灵石)、处理5(云南寻甸)风化煤对玉米芽长、根长及干物重的影响效果较好。说明腐植酸含量高且偏酸性的风化煤活性较好,对玉米发芽生长有较强的刺激作用,可为肥料新产品开发过程中选择相关的风化煤作为原料提供理论参考。

By selecting fi ve different regions of weathered coal, set up two use concentration 0.5% and 1.0%, corn germination experiment was carried out. The results show that different regions of the weathered coal due to the differences in quality, has different effects on corn shoot length, root length and dry matter weight. Overall, the treatment 3(Ningxia Shizuishan), 4(Shanxi Lingshi), 5(Yunnan Xundian) of weathered coal have better effects on corn shoot length, root length and dry matter weight. Shows high content of humic acid and partial acid weathered coal has better activity, has strong stimulation on corn sprout. That provides the theoretical reference for fertilizer in the process of new product development to choose relevant weathered coal as material.
