一种复合微生物菌剂在甜脆豌豆中的田间应用效果

为了探究复合微生物菌剂615在甜脆豌豆栽培中的田间应用效果,以甜脆豌豆品种‘长寿仁’为试材,研究了4种施肥处理（不施肥对照,单施复合菌剂615,单施化肥,化肥+复合菌剂615配施）对主要农艺性状、产量和品质、根际微生物数量的影响。结果表明：所有施肥处理可显著提高结荚率（幅度为7.90%~12.49%）,单施菌剂的病害率减少10.83%;所有施肥处理均可显著增加小区产量（幅度为10.75%~19.82%）,其中化肥与菌剂配施增幅最大(19.82%)。单施菌剂使鲜食籽粒的总糖、蛋白和淀粉含量增加50.00%、9.24%和59.37% (p<0.05),其开花结荚期根际中的细菌、真菌和放线菌数量是苗期的1.93倍、2.38倍和2.36倍,化肥与菌剂配施可提高总糖和淀粉含量(p<0.05)。综合经济和生态效益,甜脆豌豆施肥推荐化肥与复合菌剂615配施。

The Field Application Effect of a Compound Microbial Agent on Sweet and Crisp Pea

In order to investigate the application effect of compound microbial agent 615 on sweet and crisp pea cultivation, the sweet and crisp pea variety ‘Changshouren’ was used as material, the effects of four fertilization treatments (i. e. no fertilizer as control, single application of compound microbial agent 615, single application of chemical fertilizer, combined application of chemical fertilizer and compound microbial agent 615) on the main agronomic traits, yield and quality, rhizosphere soil microbial communities of sweet and crisp pea were studied. The results showed that: the pod bearing rate of sweet and crisp pea in all fertilization treatments were significantly increased by 7.90%-12.49%, and the disease incidence rate was reduced by 10.83% in the treatment of single application of compound microbial agent 615. In all fertilization treatments, the average plot yield was significantly raised by 10.75%-19.82%, among them, the combined application of chemical fertilizer and compound microbial agent 615 had the biggest increase of 19.82%. The content of total sugar, protein and starch in fresh seeds under the single application of compound microbial agent 615 was increased by 50.00%, 9.24% and 59.37%, respectively (p<0.05); and the number of bacteria, fungi and actinomycetes in rhizosphere soil at anthesis reached 1.93 times, 2.38 times and 2.36 times of those at seedling stage. The combined application of chemical fertilizer and compound microbial agent 615 improved the content of sugar and starch(p<0.05). Considering the integrated ecological and economic benefits, it is recommended that the combined application of chemical fertilizer and compound microbial agent 615 should be conducted in planting sweet and crisp pea under field condition.
