Effects of Different Quantity of Straw Mulching on Physiological Character of Winter Wheat and Soil Moisture and Temperature

With plot trial,this paper studied effects of different quantity of straw mulching on soil moisture and temperature of winter wheat,and physiological character and yield of winter wheat was compared.Different quantity of straw mulching with 0(CK),0.3(F0.3),0.6(F0.6),and 0.9(F0.9)kg/m2 were prepared as 4 treatments.The results showe that straw mulching could hold water effectively in the growth period of winter wheat;The treatment of F0.6 kept higher soil temperature,which is propitious to joint.;The yield of F0.6 was the highest compared with other three treatments,and the highest of the yield per cube meter water was F0.6,the F0.9 was second.So we believe the quantity of straw mulching at 0.6 kg/m2 is the best.
