本文研究了不同浓度三聚氰胺对高梁幼苗期各生理指标的影响,结果如下：（1）苗数、根数、苗长、根长、根鲜重、根活跃吸收面积在三聚氰胺低浓度时有促进作用，在高浓度时有抑制作用;（2）从总的趋势来看高粱苗鲜重、根总吸收面积浓度值都低于对照，高粱根活跃吸收面积所有浓度值都高于对照；（3）在10mg/ l三聚氰胺浓度时，对高梁苗期生长促进作用最为明显；（4）根据方差分析，高梁苗数、根数、苗长、根长、苗鲜重、根活跃吸收面积等相关性较好。
通过本次试验不仅能让人们对三聚氰胺有更深刻的了解，而且可为制定修改和完善我国食品安全检测制度及其环境保护和治理提供科学理论依据。
In this paper, different concentration of melamine sorghum seedling stage of physiological indicators of the impact of the results are as follows: (1) the number of seedlings, root number, seedling length, root length, root fresh weight, root active absorption area of low concentration of melamine from time to time to promote the role of in high concentration inhibited; (2) the overall trend from sorghum seedling fresh weight, root area of the concentration of the total absorption values are lower than that of control, sorghum root active absorption area of all the concentration values are higher than the control; (3) at 10mg / l concentration of melamine on the growth-promoting role of seedling sorghum most obvious; (4) According to analysis of variance,
Number of sorghum seedlings, root number, seedling length, root length, seedling fresh weight, root active absorption area, such as a better correlation.
Through the test of melamine not only allow a deeper understanding
