Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to an Aspergillus niger strain, in particular to Aspergillus niger SICU-33 for promoting plant growth and an application thereof. Background technique

[0002] Highland barley is a barley crop of the Gramineae family, a type of naked barley. Tibet is the main area where highland barley is grown. The pH of Tibetan highland barley planting soil is relatively high. The pH value of the soil in most areas is between 7.6-8.5, which is higher than the optimal growth of highland barley. pH needs; in addition, the sunshine time in Tibet is long, the water evaporates quickly, and the soil quality and fertility are generally poor. 67.89% of the farmland soil is sandy loam. Therefore, fertilizing the soil fertility of highland barley planting soil in Tibetan areas is of great significance for improving the yield and quality of highland barley, meeting the food needs of Tibetan people, and further imp...
