玉米营养体分析及其应用

Analysis and application on maize nutrition of growth.

根据1987～1999年玉米长期丰歉定位试验研究提出了玉米营养体(茎粗×株高)代替干物质量的分析方法,采用该方法可客观地揭示出玉米在不同环境条件下生长规律与产量形成的关系,且较干物质量与产量形成的关系规律完全相同,从而为研究玉米生态学增加了新的生态指标。

Based on the located experiments of high yields and failure of crop in 1987 - 1999, the analysis means of maize nutrition of growth instead of dry matter weight are brought up. The relationships between the growth orderliness and the yields formation in different surroundings are revealed, and it is the same orderliness of relations between dry matter weight and yields formation. So,new ecology indexes for researching maize ecology are increased.
