摘要
采用田间精准试验,研究了生物有机肥在提高土壤养分供应能力及影响烤烟烟叶常规成分含量方面的作用。结果表明:使用生物有机肥能够显著提高土壤供应养分的能力,同时还能够提高烟叶中钾的含量,降低烟叶中氮的含量,对提高烟叶的成熟度,改善烟叶的品质具有较大贡献。
Precision field tests were taken to study effects of combined application of bio-organic fertilizer with cake fertilizer in enhancing nutrient supply capacity of soil and increasing contents of conventional compositions in flue-cured tobacco leaves.The results indicated that applying bio-organic fertilizer can significantly enhance nutrient supply capacity of soil,while can increase content of K and decrease content of N in tobacco leaves.Therefore,it has significant contribution to improve maturity and quality of tobacco leaves.
