摘要:

【目的】 探究接种不同载体基质制备的粘质沙雷氏菌(Serratia marcescens N1.14,X-45)菌肥对植物生长、光合特性和土壤pH及速效养分的影响,筛选能有效替代泥炭的菌肥载体,为微生物肥料的研发提供参考。【方法】 以紫穗槐(Amorpha fruticosa)幼苗为对象,分别施用泥炭载体菌肥(处理T0,CK)、单一秸秆载体菌肥(处理T1)、单一麦麸载体菌肥(处理T2)、秸秆与麦麸(体积比1∶1)载体菌肥(处理T3)、秸秆和麦麸与棉籽壳(体积比1∶1∶1)载体菌肥处理组(处理T4)、秸秆和麦麸与豆饼(体积比1∶1∶1)栽体菌肥(处理T5),对比分析不同载体菌肥的施用对紫穗槐生长特性、光合特性以及土壤养分的影响。【结果】 与CK(T0)相比:①T2、T3、T4、T5处理下紫穗槐生长状况均显著提升,以T3处理最为显著;②T1、T3、T4、T5处理对紫穗槐叶片的各项光合特性指标参数均有不同程度改善效应,其中气体交换参数以T5处理改善效果最为显著,叶绿素含量以T3处理改善效果最为明显。复合菌肥载体比单一菌肥对佳士科技光合特性的改善效果更好;③T3、T4、T5处理下紫穗槐土壤养分含量有所提高。【结论】 秸秆与麦麸处理、秸秆和麦麸与豆饼处理的促生菌肥可促进紫穗槐生长发育并提高其光合效率、优化土壤营养环境、提高土壤肥力,能有效替代泥炭载体菌肥发挥效能。

Abstract:

【Objective】 This study explored the effects of Serratia marcescens N1.14, X-45 bacterial fertilizer inoculated with different carrier substrates on the growth, photosynthetic characteristics, soil pH and available nutrients of Amorpha fruticosa. Based on this, bacterial fertilizer carriers that can effectively replace rare resource peat were determined in order to provide a theoretical basis for the development of microbial fertilizers.【Method】 Taking A. fruticosa seedlings as the object, the peat bacterial fertilizer (T0, CK), straw bacterial fertilizer (T1), wheat bran bacterial fertilizer (T2), straw and wheat bran as carrier bacterial fertilizer (volume ratio = 1∶1, T3), straw wheat bran and cotton seed hull as carrier bacterial fertilizer (volume ratio = 1∶1∶1, T4), and straw wheat bran and soybean cake as carrier bacterial fertilizer (volume ratio = 1∶1∶1, T5) were applied. Through comparative analysis, the effects of the application of different carrier bacterial fertilizer on the growth characteristics, photosynthetic characteristics and soil nutrients of A. fruticosa were explored, and treatment groups that can replace peat bacterial fertilizer were selected.【Result】 Compared with CK, there were three key findings. First, the growth statuses of T2, T3, T4, and T5 were significantly improved, especially T3. Second, the photosynthetic characteristic parameters of Amorpha fruticosa leaves under T1, T3, T4, and T5 improved to varying degrees. Among the gas exchange parameters, T5 had the most significant improvement effect, and T3 had the most obvious improvement effect on chlorophyll content. At the same time, the improvement effect of compound carrier bacterial fertilizer was better than that of single bacterial fertilizer. Third, the soil nutrient content of A. fruticosa under T3, T4, and T5 treatments increased.【Conclusion】 The straw, wheat bran and soybean cake as carrier bacterial fertilizers can promote the growth and development of A. fruticosa, improve photosynthetic characteristics, optimize the soil nutrient environment, improve soil fertility, and effectively replace peat carrier bacterial fertilizer.
