Research Of High Oil Corn High Production Cultivation Mechanism And Quality Characteristic In Xinjiang Oasis

Based on the experiment with three different plant-types of high oil varieties and ordinary corn variety SC704 (comparison) respectively under five different densities was studied. The experiment indicated that the influence of physiology characteristic, canopy structure, yield formation and quality on high-oil varieties. The major object was to explore high oil corn high production cultivation mechanism and quality characteristic in Xinjiang oasis, further found out new method that could enhance yield and improve quality of high oil corn in Xingjiang oasis areas. The results were as follow:1. The results of research showed that the community's leaf area, LAI, LAD and dry matter weight to different increased degree of four variety verily with the rising of planting densities increase in the aspect of physiological characteristic. The superiority of production increment varied under different plant types, which are large individual of flat-type variety and large community of compact-type variety.2. As far as the canpoy structure are concerned, leaf orientation values and angles between stemd and leaf reduced, while leaf upward stem property in the hybridizations with different variety; the proportion of upside community leaf area increased whereas the lower part decreased; light transmittance reduced from high to low along with increased densities of the same variety, in which the flat-type variety reduced greatly while the compact-type variety reduced slightly.3. In the aspect of grain quality, the high-oil corn showed high oil and high protein while the comparison SC-704 showed high starch; the grain quality which is in high-oil variety shows downtrend but the comparison is fluctuation along with increased densities; the downtrend of oil length and protein of flat-type variety were bigger than the compact-type variety.4. In the aspect of yield, there were significant difference among the yield of economical and biological under four different varieties. The economical yield showed: Sc704 > Gaoyou 298 > Gaoyou XY-1 > Gaoyou 115; The biological yield showed: Gaoyou 298 > Gaoyou 115 > Gaoyou XY-1 > Sc704.To sum up, the best densities of Gaoyou 115 and Gaoyou 298 were both 67,500-82,500 plant/ha and the Gaoyou XY-1 was 82,500-97,500 plant/ha; the comprehensive economic efficiency per hectare of Gaoyou 115 and the Gaoyou XY-1 were 3831.2 Yuan and 4761.56 Yuan, which are higher than ordinary variety. Therefore, high-oil corn was high quality forage grass for animal husbandry development of Xinjiang.
