The Optimizing of Fertilizer Practice for Sugarcane GT 35( GT 02-901 )
摘要
Abstract
[Objective] The aim was to study the optimizing fertilization management technology of new sugarcane variety CT 35 and optimize the fertilizing schedule. [ Method] Using quaternary quadratic regression rotational combination design, the effects of planting densities, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer on the output of sugarcane GT 35 were studied, and the mathematical model was established, the fertilizing schedule was optimized. [ Result] Each cultivation factor had the greatest effect on the yield of sugarcane GT 35 and followed the sequence of phosphate fertilizer > nitrogen fertilizer > potassium fertilizer > planting densities. When, planting densities is 103 462.50 - 105 540.00 buds/hm2, urea application rate is 652. 65 - 801. 30 kg/hm2, phosphate fertilizer application rate is 1 461. 83 -1 523.70 kg/hm2, potassium fertilizer application rate is 453.23 - 477.60 kg/hm2, under this optimal situations, the yield of sugarcane will up to 87.92 t/hm2. [ Conclusion] This research will support efficient cultivation and management of programs and provide theoretical basis for GT 35 cultivated in the different ecological regions.关键词
