摘要
对广西兴宾蔗区的种蔗土壤的养分状况进行了全面的调查分析。结果表明,土壤有效N、P、K含量处于中等或中下水平,与高产土壤条件相比仍有较大差距。在各种微量元素中,B最为缺乏,其次是S、Mg,Zn、Cu和Mn也有可能缺乏。因此在甘蔗施肥时应该十分重视N、P、K肥的施用,并配合施用B、S、Mg等中微量元素,适当考虑施用Zn、Cu、Mn等微量元素。
The soil nutrient status for sugarcane planting area in Xingbin of Guangxi Province was investigated and analyzed completely. The results showed that the available N, P, K in the soil were at the middle or low-middle level, there were some differences to compare with the soil of high sugarcane yield. In all kinds of micro element, B was extremely lacking, the then were S and Mg, possibly lacking for Zn, Cu and Mn. Therefore, N, P, K fertilizers to match B, S and Mg micro elements were more concerned, and Zn, Cu and Mn in sugarcane planting soil were less regarded.
