  • 摘要:
      目的  为指导雪菜科学生产和施肥，筛选出适合雪菜生产的灵芝菌渣堆肥最佳施肥方案。
      方法  试验以绿雪菜（GL）和紫雪菜（PL）作为供试作物，设置CK（化肥，当地菜地常规施肥）、T1（化肥减量3/4 + 灵芝菌渣堆肥用量为当地有机肥常规用量的1/2）、T2（化肥减量3/4 + 灵芝菌渣堆肥用量为当地有机肥常规用量）、T3（化肥减量3/4 + 灵芝菌渣堆肥用量为当地有机肥常规用量的2倍）四个处理，分析雪菜种植后土壤pH、机械组成、有机质、碱解氮、有效磷、速效钾及雪菜株高、鲜重、根冠比、叶绿素、花青素、可溶性糖、维生素C等指标的差异。
      结果  T3更有利于提高土壤pH、有机质含量（T3 > T2 > T1 > CK）、有效磷和速效钾含量（T3 > T2、CK > T1），以及雪菜的鲜重（T3 > CK > T2 > T1）、叶绿素（T3 > T2 > CK > T1）、根冠比、可溶性糖和维生素C含量（T3 > T2 > T1 > CK）。种植PL和GL后，T3处理的土壤pH、有机质、有效磷和速效钾含量比CK分别高出0.30和0.25、6.67和3.57 g kg−1、4.74和4.40 mg kg−1、19.62和32.53 mg kg−1。而PL和GL的鲜重、根冠比、叶绿素、可溶性糖、维生素C则分别增加了2.66和5.84 g、0.02和0.04、0.12和0.20 mg g−1 FW、2.20%和0.80%、13.02和23.04 mg 100g−1 FW。
      结论  T3在有效提高土壤pH、有机质和磷钾水平的同时，也能有效提高作物产量和品质，综合肥效最好。

     

    Abstract:
      Objective  The aims were to screen out the optimal fertilization scheme of Ganoderma lucidum fungus residue compost suitable for mustard green production, in order to guide the scientific production and fertilization of potherb mustard.
      Method  The green Potherb mustard (GL) and purple leaf Potherb mustard (PL) were used as the test crops, and four treatments were set: CK (chemical fertilizer, conventional fertilization in local vegetable fields), T1(The chemical fertilizer reduction 3/4 + Ganoderma lucidum residue composting amount as 1/2 of the conventional amount of local organic fertilizer), T2 (The chemical fertilizer reduction 3/4 + Ganoderma lucidum fungus residue composting conventional local usage) and T3 (The chemical fertilizer reduction 3/4 + Ganoderma lucidum fungus residue composting twice conventional local usage). Soil pH, mechanical composition, organic matter, available nitrogen (N), available phosphorus (P), available potassium (K), plant height, fresh weight, shoot root ratio, chloride, anthocyanin, vitamin C and soluble sugar of Potherb mustard were determined planting.
      Results  T3 was more beneficial to improve soil pH, physical clay content (< 0.01mm), organic matter content (T3 > T2 > T1 > CK), available P and available K content (T3 > T2, CK > T1), and the fresh weight (T3 > CK > T2 > T1), chlorophyll content (T3 > T2 > CK > T1), root shoot ratio, soluble sugar and vitamin C content (T3 > T2 > T1 > CK) of Potherb mustard. Compared with CK, the pH, organic matter, available P and available K content of PL/GL in T3 soil increased by 0.30/0.25, 6.67/3.57g kg−1, 4.74/4.40 mg kg−1 and 19.62/32.53 mg kg−1 respectively. While the fresh weight, root shoot ratio, chlorophyll, soluble sugar and vitamin C content of Potherb mustard increased by 2.66/5.84g, 0.02/0.04, 0.12/0.20 mg g−1FW, 2.20%/0.80% and 13.02/23.04 mg 100g−1FW, respectively.
      Conclusion  T3 could not only effectively improve soil pH, soil organic matter, available P and K levels , but also improve crop growth and quality indicators, with the best comprehensive fertilizer effectiveness.
