浙江省棉花产区主要分布于杭州湾两岸的滨海平原和金衢丘陵盆地。近年来 ,随着种植结构的调整 ,棉花主产区更趋集中于海涂围垦地 ,这些地区灌溉条件相对较差 ,且新围垦地土壤盐分较高 ,棉花生产上迫切需要适应该环境种植的新品种 ,为此我们于 1 998年从中国棉花研究所引入抗旱 The cotton producing areas in Zhejiang Province are mainly distributed in the coastal plains and Jinqu hilly basins on both banks of Hangzhou Bay. In recent years, with the adjustment of planting structure, the main cotton producing areas have been more concentrated in the coastal reclamation areas. The irrigation conditions in these areas are relatively poor and the soil salinity in the newly reclaimed land is relatively high. Therefore, cotton production is urgently needed to adapt to the new planting environment For this reason, we introduced drought resistance from the China Cotton Research Institute in 1998
