    摘要:

    为明确芽孢杆菌ZJMP5与磷肥互作对红小豆根系发育和产量的影响,于2016和2017年以‘晋红5号’红小豆为材料,设置磷肥施用量[50(P1)、100(P2)、200(P3)mg·kg-1]和菌液浓度[106(A1)、107(A2)、108(A3)、109(A4)cfu·mL-1]两因素复合处理,以菌磷皆不施为对照(CK),采用盆栽试验分析芽孢杆菌ZJMP5与磷互作下红小豆幼苗根系形态、生理特性及产量的变化。结果表明:(1)各芽孢杆菌ZJMP5与磷肥复合处理(磷菌互作)均显著提高了红小豆幼苗主根长、根面积、根体积(P<0.05),幼苗主根长和根冠比均在P1A3处理下最高,分别比CK显著提高83.1%和50.9%,根面积和根体积均在P2A2处理下最高,分别比CK显著提高69.7%和54.2%。(2)各磷菌互作处理均显著提高了红小豆幼苗根系SOD活性、POD活性、根系活力和可溶性蛋白含量,且均在P2A2处理时达到峰值,并显著降低红小豆幼苗根系MDA和可溶性糖含量,且均在P2A2处理下达到最低值。(3)各磷菌互作处理均显著提高了红小豆幼苗植株P含量,并显著降低了根系酸性磷酸酶活性;随着施磷量增加,植株P含量逐渐增加,根系酸性磷酸酶活性逐渐降低;随着菌液浓度的增加,植株P含量和根系酸性磷酸酶活性均先升后降且均在A2浓度下最高。(4)随着施磷水平或者菌液浓度的增加,红小豆百粒重和籽粒产量均呈先增大后减小的趋势;各磷菌互作处理均显著提高了红小豆百粒重和籽粒产量,且均在P2A2处理组合下增产效果最佳,比对照分别显著增长了141.60%和210.40%。研究发现,芽孢杆菌ZJMP5与磷肥互作处理可通过改变红小豆幼苗根系构型、提高根系活力、改善根系生理机能来提高红小豆的籽粒产量,且在100 mg·kg-1施磷量、107cfu·mL-1菌液浓度互作下可达到最佳促生增产效果。

    Abstract:

    In this study, the purpose was to understand the effect of the interaction between bacillus ZJMP5 and phosphate fertilizer on the root development and yield of adzuki bean. The pot experiment was conducted in 2016 and 2017 using ‘Jinhong No.5’ adzuki bean (Phaseolus angularis Linn.). The experiment consisted of two factors: phosphate fertilizer and bacillus ZJMP5. Three levels of P2O5 [50 (P1), 100 (P2), 200 (P3) mg·kg-1] and four levels of bacillus ZJMP5 [106 (A1), 107 (A2), 108 (A3), 109 (A4) cfu·mL-1] were designed. Moreover, no P fertilizer and bacillus ZJMP5 was designed as control, and there were 13 treatments in our study. The root morphology, physiological characteristics and yield of red adzuki bean seedlings under different interaction levels of P fertilizer and bacillus ZJMP5 were analyzed. The results showed that: (1) the bacillus ZJMP5 and compound phosphate fertilizer treatments (phosphorus bacteria interactions) were significantly increased adzuki bean seedling taproot length, root area, root volume (P < 0.05). The seedling root length and root cap ratio are the highest under P1A3 treatment, 83.1% and 50.9%, respectively, compared with the CK significantly increased. The root area and root volume were the highest under P2A2 treatment, 69.7% and 54.2%, respectively, compared with the CK significantly increased. (2) The root SOD and POD activities, root activity and soluble protein content in the roots of rhododendrons seedlings were significantly increased by the interaction of each phosphorus bacteria, and all reached the peak value at P2A2 treatment, while MDA and soluble sugar contents in the roots of rhododendrons seedlings were significantly reduced, and all reached the minimum value at P2A2 treatment. (3) The P content of rhododendrons seedlings was significantly increased and the acid phosphatase activity of the roots was significantly decreased by the interaction of phosphorus bacteria. With the increase of phosphorus application, P content of plants increased gradually, and acid phosphatase activity of roots decreased gradually. As the concentration of bacterial solution increased, the P content of plant and the activity of acid phosphatase in root system both first increased and then decreased, and were the highest at the concentration of A2. (4) With the increase of phosphorus application level or concentration of bacterial solution, the 100grain weight and grain yield of adzuki bean increased first and then decreased. In addition, under the P2A2 treatment combination, the yield increase was the best, which increased by 141.60% and 210.40%, respectively, compared with the control group. It was found that bacillus ZJMP5 could improve the grain yield of adzuki bean by changing root configuration, increasing root activity and improving root physiological function, and the optimal effect of growth promotion and yield increase could be achieved under the interaction of 100 mg·kg-1 phosphorus application and 107 cfu·mL-1 bacterial liquid concentration.
