摘要
通过对贵州省水城县五个乡镇猕猴桃果园土壤养分含量和酸碱度的分析测定,结果表明:猴场、米箩、鸡场等乡镇猕猴桃果园的氮素和钾素含量较为丰富,但土壤的有机质含量普遍偏低,而鸡场和野钟乡猕猴桃果园的土壤速效磷含量极少,不能满足猕猴桃的生长需求;五个乡镇猕猴桃果园土壤的pH值普遍高于猕猴桃的最适生长范围,可通过在土壤中加入硫磺粉和硫酸亚铁的方式降低土壤酸碱度。
The soil nutrient contents and pH of the kiwifruit orchards from five towns in Shuicheng County, Guizhou Province have been tested. The results show that contents of nitrogen and potassium in kiwifruit orchards in Houchang, Miluo, Jichang and other towns are abundant, but the soil organic matter content is generally low. The soil available P content of kiwifruit orchards in Jichang and Yezhong is very low so that it cannot meet the growing requirement of kiwi fruit. The soil pH value of kiwifruit orchards in five towns is generally higher than that requires the optimum growth range of kiwifruit. The pH value in soil can be reduced by adding sulphur and ferrous sulphate.
