Abstract:

In order to reveal the effect of different rate of sowing quantity treatment on wheat yield formation in three different ecological regions of Gansu Province, three varieties of Longzhong No.2, Lantian No.36 and Tongmai No.6 were used as materials in each region and five sowing quantity levels (150.0, 187.5, 225.0, 262.5, 300.0kg/ha in low-temperature semi-arid region and semi-humid region, and 112.5, 150.0, 187.5, 225.0, 262.5kg/ha in semi-arid region) were set up. The variation characteristics of wheat yield and yield compositions, planting density and yield difference in different regions were studied. The results showed that the suitable sowing quantity in low-temperature semi-arid region, semi-humid arid and semi-arid region were 187.5, 225.0, 225.0kg/ha, corresponding to the highest yield of 5 472.0, 5 730.0 and 7 271.4kg/ha respectively. With the increase of planting density, the yield of wheat and the number of spikes per unit area in each ecological region showed the trend of first increasing and then decreasing, the grain number per spike decreased, 1000-grain weight had no obvious change; change trend of basic seedling and tiller heading rate were similar to that of yield; aboveground biomass increased with the increasing of planting density, and there was significant difference among different planting densities in semi-humid arid region and semi-arid region. Under the same sowing quantity (150.0 and 225.0kg/ha), the yield of different regions varied greatly, with the highest average yield in the semi-arid region, followed by the semi-humid arid region, and the lowest in the low-temperature semi-arid region.
