2013年在新疆生产建设兵团第七师130团七连8号地段大田，小麦收获的同时，秸秆粉碎还田，然后采取免耕播种和铧式犁翻耕后播种两种耕作方式，对比研究保护性耕作对北疆复播田土壤温度及复播作物生长发育的影响规律。试验结果表明：保护性耕作条件下土壤温度具有明显的阶段性变化，在复播玉米LAI达到1之前秸秆覆盖具有降温效用，土壤温度低于翻耕处理，之后则具有保温作用。整个生育期免耕田土壤温度变化平缓，累积温度、累积温差及日平均温差均低于翻耕处理。免耕处理下作物生育期后移，干物质积累主要在生育后期，产量及干物质积累略低于翻耕处理。

A field experiment was conducted at Group 130 in Xinjiang Production and Construction Corps with two tillage treatments (No-tillage and tillage) in 2013 to study the effects of conservation tillage on stubble-field soil tempera-ture and the growth pattern of corn in the reclamation region of Northern Xinjiang .The results indicated that soil tempera-tures showed interim variations under the conservation tillage .Before the LAI of corn in stubble-field reached 1 while straw mulching showed cooling effect ,the soil temperature with conservation tillage in stubble-field was lower than that with plowed tillage .Afterwards ,straw mulch exhibited insulation effect .During the entire growth period ,soil tempera-tures with conventional tillage changed smoothly .Cumulative temperature ,cumulative temperature difference and average daily temperature difference were lower than that with plowed tillage .Under no-tillage ,crop growth period was postponed with plowed tillage treatment .Dry matter accumulation happened mainly in late growth period ,and yield and dry matter accumulation were slightly lower than those with conventional tillage .
