摘要
根据 1998年 3～ 5月≥ 0℃积温变化的动态模型 ,研究了青刈黑麦干物质积累及蛋白质含量与积温的非线性关系。
A dynamic model about the change of cumulative temperature from March to May in 1998 was built. On the basis of it, the nonlinear relationship between the accumulation of dry matter and the content of protein in rye and cumulative temperature was studied.
