The new variety Ninghongmai 452 was used as test material,and six sowing date and density combinations were set up.The effect of different sowing dates and densities on the yield and quality characteristics of Ninghongmai 452 was studied.The results showed that the highest yield was obtained when the sowing date was October 20 and the density was 2.7×106 plants/hm2.Late sowing treatment decreased the yield of Ninghongmai 452,but did not reach a significant level.Ninghongmai 452 has the characteristics of more spike number,less variation in spike length and grain weight,which can meet the demand of large scale wheat cultivation in rice stubble.Ninghongmai 452 exhibited strong gluten characteristics such as long stabilization time,large maximum tensile resistance and tensile area in all experiment treats of sowing date and density combinations.Among them,the quality of dough treated with sowing date of November 5 and density of 2.7×106 plants/hm2 was the best.
