AI Technical Summary

Technical Problem

The growth of drought-resistant alkali wheat is restricted in saline-alkali soil, which is manifested by uneven emergence of seedlings, missing seedlings and broken ridges, few tillers before winter, few secondary roots, and it is easily affected by low temperatures and frost damage in winter, which affects yield.

Method used

A composite microbial agent is used, consisting of Bacillus oceanica HMF13 and Paenibacillus gelatinosa HM-7, combined with granular organic fertilizer, a binder and an anti-caking agent. The preparation method includes mixing and freeze-drying, and the agent is applied to saline-alkali soil to improve soil properties.

Benefits of technology

Significantly increase the number of front tillers and secondary roots of drought-alkali Ophiopogon japonicus, reduce the pH of saline-alkali soil, increase the organic matter content, enhance cold resistance, and increase yield.

Abstract

The present invention relates to a composite microbial agent, which comprises oceanic Bacillus HMF13 and jelly-like Paenibacillus HM-7; the oceanic Bacillus HMF13 has a deposit number of CGMCC No. 30479; the jelly-like Paenibacillus HM-7 has a deposit number of CGMCC No. 29734. In the composite microbial agent, the total viable count is not less than 5×10 8 The ratio of the viable bacterial counts of the oceanic Bacillus HMF13 and the jelly-like Paenibacillus HM-7 is 1 to 2: 1. The composite microbial agent of the present invention can not only improve saline-alkali soil but also increase the cold resistance and yield of drought-resistant alkali wheat.
