Abstract:

To increase maize yield and efficiency through high-density planting with limited nitrogen input, it is necessary to further explore the potential of light-nitrogen matching utilization of dense-tolerant varieties. Revealing the spatial distribution and matching characteristics of light and nitrogen in canopy in canopy of different density-tolerant varieties, and their relationship with maize yield formation and nitrogen efficiency, is of guiding significance for exploring the reduction of maize yield and efficiency hierarchy differences. In this experiment, the conventional variety KH8 and the high-density tolerant variety MC670 were used as the experimental materials. The planting density was set at 82,500 plants hm-2 and the nitrogen application rate was 150 kg hm-2, systematic analysis of the different varieties of dense canopy light resistant nitrogen differences in spatial distribution and matching characteristics. The results showed that the transmittance of MC670 was 20.6% significantly higher than that of KH8. SLN (specific leaf nitrogen) of upper and middle leaves was significantly higher than that of lower leaves in both cultivars. The SLN of upper and middle leaves of MC670 was significantly higher than that of KH8, but the difference of lower leaves was not significant. The matching coefficients of light and nitrogen for KH8 and MC670 were 1.28 and 0.86, respectively. The difference between the matching coefficients of light and nitrogen for MC670 and the ideal value was small, indicating that the matching degree of light and nitrogen for MC670 was better than KH8. In conclusion, compared with the conventional varieties KH8, the canopy of high-density resistant varieties MC670 had lower extinction coefficient and higher nitrogen reduction coefficient, which made the canopy of high-density resistant varieties had a better light nitrogen matching degree. Meanwhile, the middle and upper canopy had higher ratio of light and nitrogen, photosynthetic productivity, and photosynthetic nitrogen ratio. This is an important physiological factor to achieve higher nitrogen physiological efficiency, nitrogen use efficiency and high yield.

Key words: maize, canopy, photo-nitrogen matching, nitrogen use efficiency
