在甘蔗上连续四年施用含氯化肥的长期定位试验,结果表明:在等氮、磷、钾养分条件下,含氯化肥的施用对甘蔗的蔗茎产量和蔗糖产量未产生显著不良影响;蔗叶和蔗汁的氯含量随施氯量的增加而增加,但施氯量对蔗叶和蔗汁中氮、磷、钾含量无不良影响;在第四年,施氯量最大的处理,其0~20cm土层土壤的氯含量较基础土壤仅增加15~17mg/kg;施含氯化肥可使土壤pH值降低。因此,含氯化肥可以在甘蔗上使用,但在酸性土壤施用,应适当配合碱性肥料,防止土壤的酸化。
The results of long-term experiment on the application of chlorinated fertilizers on sugarcane for four consecutive years showed that the application of chlorinated fertilizers did not have a significant adverse effect on the yield of cane and the yield of sucrose under the conditions of nitrogen, phosphorus and potassium nutrients; Chloride content in leaves and sugarcane juice increased with the increase of chlorine application rate, but the amount of chlorine application had no adverse effect on the contents of nitrogen, phosphorus and potassium in sugarcane leaves and cane juice. In the fourth year, The content of chlorine in 0 ~ 20cm soil layer was only increased by 15 ~ 17mg / kg compared with the basic soil. The application of chlorinated fertilizer could reduce the soil pH value. Therefore, chlorinated fertilizers can be used on sugar cane, but in acidic soil application, should be properly with alkaline fertilizers to prevent soil acidification.
