Abstract:

In this paper, the meteorological suitability indexes at key growing stages of seed maize in Zhangye were studied, the meteorological conditions and meteorological factors were examined and the climate quality certification technology of seed maize in Zhangye was discussed. Based on the data of air temperature, precipitation, sunshine duration from the Zhangye National Reference Climatological Station, the effects of meteorological factors in 2020, including heat, light, precipitation and etc., on the growth of seed maize were analyzed, and the assessment of the climate quality grade certification of seed maize in Zhangye was carried out. The results showed that the temperature and sunshine in 2020 were conducive to the growth and quality formation of seed maize; the summer drought and diseases had certain influence on the development of seed maize, and the cultivation base of seed maize should take steps to reduce the hazard degree. According to the geographic regionalization index of seed maize, the climatic conditions of maize growth of the year and the production management of seed maize enterprises, the climate quality grade of seed maize in the certified region is excellent.

Key words: Zhangye, meteorological condition analysis, climate quality certification, seed maize
