本试验研究了内蒙古临河地区甜菜生产中3项主要农艺措施对甜菜经济性状的影响及数量关系。其结果表明:密度是影响块根产量的关键因素,其次是追肥,最后是种肥;3因子对块根含糖率的影响依次是种肥>密度>追肥;若从单位面积的甜菜产糖量来看,3因子的贡献率依次是追肥>密度>种肥。另外,在全面分析各农艺措施的主效应及互作效应的基础上,确立了临河地区甜菜产糖量8250kg/hm2以上的优化栽培措施,其密度为91500~96000株/hm2,种肥N38.55~54.3kg+P2O532.8~138.75kg/hm2,追肥N124.65~158.25kg+P2O541.55~52.9kg/hm2。
In this study, the effects of three major agronomic practices on the economic traits of sugar beet in beet production in Linhe, Inner Mongolia, and their quantitative relationships were studied. The results showed that: the density is the key factor affecting root yield, followed by top dressing, the last is the kind of fertilizer; 3 factors on the rate of content of sugar in turn followed by a kind of fertilizer> density> top dressing; sugar yield per unit area See, the contribution rate of three factors followed by top dressing> density> kind of fertilizer. In addition, on the basis of a comprehensive analysis of the main effects and interaction effects of various agronomic practices, optimized cultivation measures for sugar beet production in the Linhe area above 8250kg / hm2 were established, with densities ranging from 91500 to 96000 plants / hm2 and seed fertilizer N38. 55 ~ 54.3kg + P2O532.8 ~ 138.75kg / hm2, topdressing N124.65 ~ 158.25kg + P2O541.55 ~ 52.9kg / hm2.
