摘 要: | /[目的]探讨甘蔗测土配方施肥对甘蔗农艺性状及经济效益的影响。[方法]设测土配方组(按智能化土壤诊断施肥建议卡使用肥料量)、复合肥组(N:P:K-~15:15:15)、常规组(滤泥配施N、P、K肥,按当地甘蔗施肥量)、空白组(可获得基础地力产量,即不施肥产量),并对4个组的农艺性状及经济效益进行分析评价。[结果]与空白组相比,复合肥组、常规组、配方施肥组产量分别增加52.7%、10.5%、18.7%,含糖量分别增加53.5%、12.1%、18.3%,净增效益分别增加20%、2.5%、12.8%。[结论]测土配方施肥后,甘蔗可增产、增糖,经济效益高,值得大田推广应用。

Abstract: | [ Objective ] The research aimed to investigate the effects of soil testing and fertilizer on sugarcane agronomic traits and economic effi- ciency. [ Method] Fertilization treatment (diagnostic soil fertilizer recommendations by intelligent use of fertilizers card volume), compound fer- tilizer (N: P: K content of 15: 15:15 ), conventional treatment (filter mud fertilizer N, P, K fertilizer, according to the local sugar cane fertilizer) were set. And available fertility yield basis, scilicet no fertilizer production was taken as control. Agronomic traits and economic analysis of four treatments were studied. [ Result] Compared with the blank fertilization group, the yield of fertilizer group, the conventional group respectively increased 52.7%, 10.5% and 18.7%, the sugar yield increased 53.5%, 12.1% and 18.3% ,and the net benefits were increased 20%, 2.5% and 12.8%. [ Conclusion] After soil testing and fertilization, sugarcane could increase yield, high economic efficiency, which was worth for field application. |
