摘要:

苹果再植病(ARD)主要由生物因素引起,严重制约了苹果产业的发展。采用生物防治措施缓解 ARD 对苹果产业的可持续发展至关重要。以平邑甜茶幼苗和嫁接苗(Fuji New2001/M9T337)为试验材料,在盆栽和大田条件下研究了生氨基酸粉和哈茨木霉菌肥对植株生物量、叶片指、根系指、土壤理化性质、土壤酶活性和土壤真菌群落的影响。我们发现,施用两种物质显著促进了植物生长,提高了叶片光合作用叶绿素含量、根系呼吸速率、根系抗氧化酶活性和土壤酶活性,显著降低了土壤中镰刀菌数量,显著提高了有益菌的丰度。综上所述,生氨基酸粉与哈茨木霉菌肥混施是防治ARD的有效方法。

Abstract:

Apple replant disease (ARD) is mainly caused by biological factors, and it severely restricts the development of the apple industry.  The use of biological control measures to alleviate ARD is critically important for the sustainable development of the apple industry.  The effects of raw amino acid powder and Trichoderma harzianum fertilizer on plant biomass, leaf and root indexes, soil physical and chemical properties, soil enzyme activities, and the soil fungal community were studied under pot and field conditions using Malus hupehensis Rehd. seedlings and grafted trees (Fuji New 2001/M9T337) as experimental materials.  We found that the application of the materials significantly promoted plant growth, increased the leaf photosynthesis and chlorophyll content, root respiration rate, root antioxidant enzyme activities, and soil enzyme activities, significantly reduced the number of Fusarium sp. in soil, and significantly increased the abundance of beneficial fungi.  In conclusion, the mixed application of raw amino acid powder and T. harzianum fertilizer is an effective method for the prevention and management of ARD.
