西北与东北草高梁比较研究

Comparative research of northwest and northeast sorghum grass

通过对西北和东北草高粱的比较研究.结果表明:西北草高粱的生育期比东北草高粱稍早;而在生长势、植物学性状、生物产量、呼吸速率均是西北草高粱优于东北草高粱,只有叶绿素含量东北草高粱优于西北草高粱;综合性状以西北草高粱晋草5号表现优异,可以引种于珠三角腹地大面积推广。

The comparative study of northwest and northeast of sorghum grass showed that:sorghum grass in the northwest of the groving period than the northeast earlier in the sorghum grass.In growth potential,botanical characters,biological production,respiration rate of sorghum grass in the northwest were superior to the northeast sorghum grass,only the chlorophyll content of northeast sorghum grass wasbetter than northwest sorghum grass.Better integrated traits were sorghum grass in the northwest Jincan No.5,which ...
