High yield cultivation mathematical model and its application on maize new hybrid Xixiangban99
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 2
Abstract
In this experiment，quadratic orthogonal regressive rotation design of five factors were used to study the effects of planting factors such as sowing date，density，nitrogen，phosphorus and potassium on the yield stability of maize variety Xixiangban 99. The results showed that sowing time，planting density ，N application amount，P2O5 amount and K2O amount were significantly correlated with yield of maize. If Xixiangban99 reaches the stable yield range of 7 500-9 750 kg/hm2，it needs to be sowed in March 4-11，and planting density is 51.8～57.9 thousand plants per hectare，and N is 128.25～207.75 kg/hm2，P2O5 is 67.05～108.15 kg/hm2 and K2O is 101.55～171.00 kg/hm2. The ratio of N∶P2O5∶K2O is 1∶0.5∶0.8. This study provided a theoretical basis for large area production of maize hybrids Xixiangban 99.
