| 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 temperature and the growth pattern of corn in the reclamation region of Northern Xinjiang. The results indicated that soil temperatures 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 temperatures 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. |
