Abstract:
      To determine the appropriate sowing density and planting date for wheat in Guanzhong area, wheat variety Pubing 151 was used as the test materials planted on October 3, October 8, and October 13, and also with plant densities of 1350, 1950, 2550 and 3150 thousand seedlings per hectare. The consequences of sowing date and density on grain yield and quality of Pubing 151 were investigated. The results showed that the yield of Pubing 151 was decreased with the delay of sowing date. Spike number of wheat was increased through the increase of planting density, resulting in the improvement of wheat yield. Based on the effect of the combination between sowing date and density, the appropriate sowing date was from October 3 to October 8. Seeding rate was increased along with the delay of sowing date from October 3, 1950 thousand seedlings per hectare to October 8, 2250 thousand seedlings per hectare. With the delay of sowing date, protein content and wet gluten content were decreased, whereas sable time was increased. When the planting density was 2550 thousand seedlings per hectare, protein content, wet gluten content and sable time reached the maximum values as 14.25%, 30.72% and 10.22 min, respectively. Therefore, based on production need, the proper sowing date and planting density would need to be determined to ensure the coordination of yield and quality of wheat.
