Abstract: In order to explore the effects of deep plowing on grain filling of winter wheat,four treatments including rotary tillage(CK) and three tillage depths(30,50,70 cm) were used in field experiment.Our results showed that deep plowing increased the SPAD of flag leaf and delayed the senescence of wheat;soil water content,photosynthetic physiological and grain weight were also improved.Further studies revealed that deep plowing up regulated Rmax and Rmean,,Wmax appeared later.The results suggested that deep plowing increased the yield of winter by increasing grain weight and harvest index.The results suggested that P30 and P50 treatments increased the yield of winter by increasing grain weight and harvest index.The soil water content of P50 was higher than P30.The most effective way to increase the yield of winter in agricultural production is deep plowing.
