Effects of Different Chemical Fertilizers Application Rates and Densities on the Whole Growth Period of Sorghum in Semi-Arid Areas of North China

Abstract:

Sorghum is one of the most important economic crops in the semi-arid areas of northern China. However, its yield is still relatively low, and some factors, such as the amount of different chemical fertilizers application and planting density, limit the increase of yield. In order to study the effect of fertilizer application rate and planting density on the growth and yield of sorghum, Longza 16 was used as test variety material, and the experiment was conducted with the split plot design. The fertilizer application (375kg/hm2(N:P:K=1:0.7:0.4), 375kg/hm2(N:P:K=1:0.7:0.8), 375kg/hm2 (N:P:K=1:0.7:1.6), 750kg/hm2（N:P:K=1:0.7:0.8), 750kg/hm2（N:P:K=1:0.7:1.6)) was designed as main plot and planting density (96000 plants/hm2, 109000 plants/hm2, 128000 plants/hm2, 154000 plants/hm2）was arranged as subplot. The photosynthetic parameters and yield-related characters were determined during the whole growth period of sorghum. The results showed that the effect of fertilizer application on the yield of sorghum was significant. The yield increased with the increase of fertilizer application, and the yield of 750kg/hm2 (N:P:K=1:0.7:1.6) was significantly higher than that of other treatments. Different planting densities also had a significant effect on the yield, showing that the yield increased with the increase of density, and the yield was the highest under the density of 154000 plants/hm2. In addition, the result of composite effect of fertilizer application rate and density showed that the yield of the treatment of 750kg/hm2 (N:P:K=1:0.7:1.6) and 154000 plants/hm2 was the highest, which was considered to be more suitable for the production of sorghum in the semi-arid areas of northern China.
