Study on Theory and Technology of Growing for High-yield in Compact Corn

Using the split plot and multi quadric regressive orthogonality rotary combination design,corn variety Denghai 6's yield and yield components,important colony quality and physiological index, microclimate index in field and technical planning for high yield were studied. The high yield planting theoretical index and the methods of planting between rows were obtained in the experiment. The results showed that Denghai 6 had the great potential of increase yield. The average yield in two years was 12510kg/ha for 13 85ha, the highest grain yield (754 7m 2) was 15477 kg/ha. The ecoclimatic conditions can meet the needs in growing for high yield during the whole growth stage of corn in the mountain area of Northwest Guizhou.
