Abstract


High-oil corn and other three different types of corn hybrids (including high-starch , high-quality protein and compact ordinary high - yielding corn ) , high oil corn grain nutritional quality of the formation process, grain Nutrition in and accumulation characteristics slightly different with the other three types of corn hybrids , all types of corn grain dry matter and starch , crude protein and fat accumulation are in line with the \rapid accumulation of starch of 20 days to 50 days , 30 to 50 days of protein , fat accumulation and rapid ; parabola changes in the grain growth process , the starch content and the fat content , the fat content of the high-starch corn starch content and high oil corn more than other types of protein content could be described by the equation Y = X ( A BX ) said . The trial production control law on the high - oil corn , high oil corn oil 1 spring for the test material, the use of 2 saturated D-optimal design . Explore the fertilizer , the density of the impact of high oil corn grain yield and fat yield results show that : nitrogen , phosphorus, potassium , and density of the impact of high oil corn grain yield and fat yield showed a parabolic equation Y = A BX CX 2 each factor has one of the best value ; significant interaction effect between the four factors , each factor values ??in the appropriate range , high oil corn grain yield can be improved and fat production ; processing the difference in fat content was significantly less than the difference in grain yield , the impact of various factors on grain yield and fat yield ; University experiment Station conditions , when the per hectare N : 328kg P - 2 < / sub > O 5 : 118kg K 2 < / sub > O : 150kg density of 57,500 / ha , high - oil corn production up to 9746 kg .
