通过布置田间小区试验,研究了不同农林废弃物制成的5种改良剂对烟稻轮作土壤性状和烤烟生长发育、产量和烟叶品质的影响。不同改良剂施入土壤后,土壤体积质量较不施改良剂的对照处理显著下降,而田间持水量明显提高,表明烟田土壤物理性状得到明显改善。改良剂能明显促进不同生育期烟株的生长:烟株团棵期,改良剂X1处理叶片宽显著高于对照;旺长期,X1、X2、X5处理叶长显著大于对照,且X5处理叶面积显著大于对照;成熟期,X1、X2、X5处理上部叶和下部叶长显著高于对照。改良剂能增加烟叶产量,尤其是改良剂X3、X5,明显增加了上等烟和中等烟的产量。改良剂X1、X2、X3处理上等烟总分显著高于对照,即改良剂处理烤出的上等烟综合品质更优。
Field experiments were conducted to study the effects of five amendments made from different agricultural and forestry wastes on soil properties and growth, yield and leaf quality of tobacco. When different amendments were applied to the soil, the soil volumetric weight decreased significantly compared with the control without treatment, while the water holding capacity in the field increased significantly, indicating that the physical properties of tobacco soil were significantly improved. At the growth stage of X1, X2 and X5, the leaf length of X1 was significantly higher than that of the control, and the leaf area of X5 was higher than that of CK Significantly higher than that of the control. At maturity, the upper and lower leaves of X1, X2 and X5 treatments were significantly higher than those of the control. Improver can increase the yield of tobacco, especially modifier X3, X5, significantly increased the yield of superior and moderate smoke. X1, X2, X3 modified treatment of superior smoke total score was significantly higher than the control, that is, improved agent treatment baked superior tobacco comprehensive quality is better.
