    摘要:

    利用筛选获得的高效溶磷微生物菌株,选择不同的载体和保活材料研制成不同配方的溶磷微生物肥料,并通过盆栽试验验证其效果。结果表明,不同配方的溶磷微生物肥料均可以活化土壤难溶态磷,同时可以协同增加玉米植株的氮、磷、钾累积量,对玉米生长及产量也有积极的促进作用。从玉米单穗粒重分析,以F为载体适宜配方的增产效果为配方3>配方2>配方1>配方4>基质对照,增产幅度分别为25.33%、14.47%、11.05%、9.55%、5.81%;以Y为载体的适宜配方增产顺序为配方3>配方4>基质对照>配方2>配方1,增产幅度分别为25.03%、24.85%、22.55%、12.87%、1.05%。从植株养分积累情况分析,Y2和Y3处理的玉米植株氮、磷和钾含量与单施化肥的处理相比,增幅分别达到75.09%和62.65%;35.08%和32.89%;40.21%和46.47%。综合玉米长势、土壤速效磷含量、植株氮、磷和钾积累量以及收获后产量等指标,以Y为载体配方3(Y3)处理的效果最好。

    Abstract:

    Using the selected high efficient phosphate solubilizing strains, and mixed it with different carri-ers and vitality keeping materials, different formulations of phosphate solubilizing microbial fertilizers were devel-oped, and their effect was verified by the pot experiment. The results showed that all kinds of phosphate solubilizingmicrobial fertilizers could activate insoluble phosphorus in the soil, also could synergistically increase maize totalphosphorus, total nitrogen and total potassium accumulation, which has a positive influence on the growth and yieldof maize. Using single ear yield as index, analysis showed that for the vector F, yield increased according to such or-ders: formulations 3> formulations 2> formulations 1> formulations 4> matrix. Compared with the control, yield in-creased by 25.33%, 14.47%, 11.05%, 9.55%, 5.81%, respectively. For the vector Y, yield increased according tosuch orders: formulations 3> formulations 4> matrix > formulations 2> formulations 1. Compared with the control,yield increased by 25.03%, 24.85%, 22.55%, 12.87%, 1.05%, respectively. For the plant nutrient absorption, com-pared with fertilizer treatment, the plant nitrogen, phosphorus and potassium content of Y2, increased 75.09%,35.08% and 40.21%, which of and Y3 treatment was 62.65%, 32.89% and 46.47%. Comprehensive analysis of corngrowing, available phosphorus content in soil, total nitrogen, total phosphorus, total potassium accumulation in plants, crop production and other indicators, Y3 treatment was the best.
