【摘要】 [目的]为了给福泉市烟区进行精准配方、平衡施肥提供参考。[方法]利用GPS定位,在福泉市植烟土壤上相对均匀地采集了180份土样,并对土样的主要养分含量和p H值进行了测定。[结果]福泉植烟土壤有机质、有效氮、有效磷和速效钾含量的平均值分别为26.8 g/kg、134.1 mg/kg、35.9 mg/kg和222.1mg/kg,变异系数分别为25.8%、21.4%、72.1%和55.3%;土壤p H平均值为6.2,变异系数为15.3%。[结论]福泉市植烟土壤有机质、有效氮、有效磷和速效钾含量在总体上均丰富,但各乡镇之间差异较大,应根据养分丰缺情况和p H值,精准确定烤烟施肥种类和用量。更多还原

【Abstract】 [Objective] The research aimed to provide the reference for the precise formula and balanced fertilization of tobacco production in Fuquan City, Guizhou Province. [Method] 180 soil samples were gathered from Fuquan City by G1oba1 Position System(GPS) fixed position. The main nutrient contents and p H value were analyzed. [Result] The average contents of organic matter, available nitrogen,available phosphorus, available potassium in tobacco planting soil were 26.8 g/kg,134.1 mg/kg, 35.9 mg/kg, and 222.1 mg/kg respectively, and the coefficient of variation were 25.8%, 21.4%, 72.1%, and 55.3% respectively. The p H value of tobacco planting soil was 6.2, and the p H value coefficient of variation was 15.3%. [Conclusion] The organic matter, available nitrogen, available phosphorus, available potassium contents were abundant in the mass, but there were big difference among different towns. The precise fertility types and precise fertility dosage should be determined according to the main nutrient state and p H value of tobacco planting soil in Fuquan city.更多还原
