Abstract:
A 3-factor and 2-degree common rotary design was used to analyse and simulate the main agronomical practice for high-yielding wheat in Hetao irrigated area of Inner Mongolia, and it was determined that the optimal sowing amount of seeds was 18-23 kg/mu, while N and P2O5 were applied at the rates of 20-23 kg and 10-13 kg/mu respectively. The correlation among yield, application of N and P and sowing amount was determined for high-yielding spring wheat cultivation. It was found that density tended to decrease with higher target yield while more N and P fertilizers should be applied.
