| Abstract: | A field experiment was conducted to study the effects of foliage spraying selenium-nutrients on the botanical characteristics,economic characteristics,economic benefits,exterior quality and the Se-content of summer sweet corn in alpine region.The results showed that spraying selenium-nutrient in the early filling stage,the grain yield and Se-content improved obviously,and the similar results were found in botanical characteristics and economic benefits.The leaf stay-green increased by a big margin,and the weight of fresh bract and fresh ear increased by 26.5% and 24.0%,and the fresh kernel weight reached 170 g,and the growth rate reached 43.9%,the rate of seed and 100-seed weight increased by 16.0% and 28.7%;Selenium content in corn is 0.17 mg / kg,which reached the standard of selenium-rich.In short,selenium-nutrient sprayed had comprehensive advantages in summer sweet corn. |
