The results showed that Xianyu 335, ND8 and ND2 were better than other cultivars in these agronomic traits. Multi- factor comprehensive appraisal with simple computing, comprehensive and reason- able results is suitable to be used for evaluating the performance of hybrid maize cultivars in field.展开更多

The status quo of the agricultural and the internal structure of agriculture in Yimeng Mountainous area are analyzed through the method of comprehensive appraisal of the improved factors. The safety coefficient of the comprehensive appraisal is from 2.626 696 to 4.987 546,which is exclude in the safety extent, so it needs adjusting. At the same time, the internal relations of the internal structure of agriculture in Yimeng Mountainous area are studied by using the relativity analysis. The overall agricultural structure of Yimeng Mountainous area is in negative correlation to planting structure and forestry structure, and in positive correlation to livestock breeding industry; the plating structure is in negative correlation to livestock breeding structure and in positive correlation to forestry structure and the forestry structure is in negative correlation to livestock breeding structure.展开更多
