【摘要】 根据第二次土壤普查资料显示,内蒙古东四盟、市的中、重盐碱化和盐、碱土此类型荒地和耕地面积有81.9万hm2,可开发栽植糖用甜菜,促进糖产业发展。通过研究、分析,参考国外糖用甜菜对养分的吸收和移出量,提出调整N∶P2O5=1∶0.375~0.400为1∶1.2,K2O和Mg O施用量为吸收和移出量的1/3,Zn按土壤含量适当施用,Mn、B按吸收和移出量补施,在施有机肥的基础上,参考施肥方案。更多还原

【Abstract】 According to the second data of land census, there are 819 000 hm2saline-alkali soil,wasteland and arable land in the east part of Inner Mongolia.It can develop planting sugar beet production to promote sugar industrial development.Through research and analysis,after referencing to foreign research on the amount of sugar beet ’s nutrient absorption and remove,I propose a adjustment made N∶P2O5=1∶0.375~0.4 to 1∶1.2,the amount of K2 O and Mg O administering should be 1/3 of the amount of absorption and remove,Zn should be fertilized according to the soil content appropriately.Mn and B should be fertilized according to amount of absorption and remove,on the basis of organic fertilizer,reference fertilization program.更多还原
