Abstract
[Objective] To provide scientific basis for the large-area planting and application of Guidan 0811 in Guangxi.[Method] With Guidan 0811 as the test materials,416-B regression optimum design was adopted.Guidan 0811 was planted in spring and autumn 2015,so as to research the relationship between yield of Guidan 0811 and N,P and K dosage and planting density.The fertilizer and density equation were established;and the main effect and interaction effect of the four factors on yield were analyzed.[Result]All the 4 factors performed upward parabolic change, and their influences on Guidan 0811 yield of in the two seasons from big to small were in the order of density ,N fertilizer,P fertilizer and K fertilizer.Analysis of regression model showed that the optimum planting density was 69321-90000 plants/hm2 and N,P and Kfertilizer levels were 112.50-186.60,37.50-62.25 and 93.75-155.55 kg/hm2,respectively.[Conclusion] Guidan 0811 is tolerant to high density planting,and there is not significant differences in yield among the densities of 75000,81000,87000 and 93000 plants/hm2 .However,considering the planting condition of corn in Guangxi,the density of 63000-69000 plants/hm2 was recommended for Guidan 0811 in the large-scale promotion and demonstration.关键词
