为了探索早熟棉花品种在南疆干旱区滴灌条件下不覆膜（裸地）栽培技术，2014年叶尔羌河试验站进行了南疆早熟棉品种裸地栽培试验。结果表明：裸地栽培可适当推迟打顶时间，也可根据具体苗情而定；各品种裸地栽培单铃重、衣分均无太大差异，但绒长都较覆膜栽培的短，说明裸地栽培对品种的单铃重、衣分没有太大影响，但对绒长有一定的影响。裸地栽培个别品种在采收过程中有夹壳现象。

In order to explore the no mulching cultivation techniques under drip irrigation in arid area in south of Xin-jiang,Yarkant River experiment station couducted the bare cultivation test of early maturing cotton varieties in South of Xin-jiang in 201 4 . The results showed that:bare cultivation could defer the topping time properly,can also according to the spe-cific growth . All varieties depending on bare land cultivation;Single boll weight,lint percentage had no much differences,but cashmere length was short compared with film mulching cultivation,It explained that the influence of bare cultivation on variet-ies were not too big in boll weight and lint percentage,but had certain effect on the fiber length . Individual species of bare land cultivation had clamping shell phenomenon in the harvesting process .
