在粤西地区缺镁土壤上设置田间试验.结果表明,土壤交换性镁低于20mgkg~(-1)情况下,施用镁肥,对经济作物有明显的增产效果,甘蔗增产47.1～60.9%,辣椒增产15.9～19.8%.香蕉增产作用虽不明显,但可改善其品质和耐贮性能.
Field experiments were conducted on magnesium deficiency soils in western Guangdong.The results showed that applying magnesium fertilizer under the condition of soil exchangeable magnesium below 20mgkg -1 could obviously increase the yield of economic crops and increase the yield of sugarcane by 47.1-60.9% Pepper yield 15.9 ~ 19.8% .Banban yield increase is not obvious, but can improve its quality and storage performance.
