title: [Ecophysiological characteristics and productivity of wheat-cotton community].
abstract: The eco-physiology and productivity of 6-2-2 wheat-early maturing cotton-middle maturing cotton were studied in comparison with traditional 6-2 wheat-middel maturing cotton. The results showed that after wheat harvested, the LAI of cotton increased fast, the leaf area duration(LAD) and CGR were raised obviously, the dry matter rose rapidly, and the accumulated amount was larger than CK. Light use efficiency was 1.13%, 21% more than CK. The effective blossom period was extended 18 d, and the lint yield in both 1998 and 1999 was over 2250 kg.hm-2, 21-22% more than CK.
