【摘要】 对北方地区冬季菹草产氧力进行了研究 ,结果表明 :菹草冰下产氧量在 10 0 0 0LX以内有随光照强度增加而增大的趋势。 2 5℃时菹草光补偿点为 99LX ,其光饱合点为 1374 9LX。更多还原

【Abstract】 The oxygen productivity of under-ice potamogeton cripus in northern area was studied.The result showed when the illumination was below 10000lx the oxygen productivity of photosynthesis of under-ice.at 2.5℃,the compensation point of light of potamogeton crispus was 99LX,and the saturation point of light of it was 13749LX.更多还原
