| Abstract: | Objective] By setting different densities and fertilization levels,Yueyou No.13 cultivation model for high yield and high efficiency was explored.Method]Two-factor and three-level randomized block design was used to study the effects of different planting density and fertilizer levels on yield and agronomic characteristics of Yueyou No.13.Result] Under the conditin of Yueyou No.13 planting density of 300 000 /hm2,enough base fertilizer(bio-organic fertilizer 2 250 kg/hm2 + compound fertilizer 300 kg/hm2),seedling stage topdressing N amount of 76.6 kg /hm2,P2O5 amount of 48.8 kg /hm2,K2O amount of 126 kg/hm2,better yields could be obtained. Conclusion]In hilly upland red soil,different density had significant impact on Yueyou No.13 yield,and fertilizer levels had very significant impact on Yueyou No.13 yield. |
