The regional characteristics of wheat cultivation are quite obvious. The same varieties and quality vary widely around the world. Between the locations where the latitude and altitude are very different, the grain protein, its components and lysine content are in different varieties. There are significant differences between. In this experiment, multi-annual off-site planting trials were conducted in wheat fields of the Tibetan wheat district, Huanghuai winter wheat region, and northern winter wheat region, including spring sowing and autumn sowing experiments to investigate the effects of latitude and elevation on some wheat quality traits. To provide some experimental basis for the cultivation of high-quality Tibetan wheat. The determination of the quality of wheat requires the use of various types of instruments for the determination of the fall value of the wheat can be accurately measured.

Eco-altitude is the product of latitude and altitude. Latitude and altitude as important terrain factors can affect the growth period of wheat, and it cannot ignore its impact on quality. In a similar study in which wheat varieties were planted off-site for many years, only the crude protein and lysine contents were determined and it was found that the ecological height was negatively correlated with them. In this study, the correlation coefficient between the NIR protein content, wet gluten content, sedimentation value, and fall value of the tested varieties in the autumn and spring sowing tests was compared with the experimental ecological height. The quality traits of the tested varieties in the autumn sowing and spring sowing experiment were all negatively correlated with the ecological height (except for the NIR protein content and sedimentation value of the Shan 229). The contents of NIR protein, fall value, wet gluten content and ecological height of grain of Xiaojing 6, Shaan 229, and Feimai were negatively correlated with each other. The NIR protein content of Yunchun 16 was significantly negatively correlated with ecological height.
The determination of wheat samples by the fall-value meter was negatively correlated with the wheat grain protein content, wet gluten content, sedimentation value, and fall value, regardless of the spring sowing or autumn sowing test, and the partial quality of some varieties. The trait indicator even showed a significant or extremely significant negative correlation. This is a conclusion drawn from experiments conducted at five latitudes and different altitudes. It represents the basic conditions of the three wheat regions in China from the southwest to the northeast. The author has analyzed the autumn seeding test data of eight experimental sites in Yangling, Linfen, Zhengzhou, Xuzhou, and Shijiazhuang in Kunming, Dali, Hanzhong, and Huanghuai districts in the southwestern wheat region. Similar experimental conclusions have also been reached. According to the conclusion of this study, within the coverage range represented in this paper, it seems that wheat is planted in a site with a higher ecological height, which is not conducive to the increase of grain protein content and gluten content, and it is also not conducive to improving the processing quality of flour, but may be beneficial to improve A. Amylase activity.
