Efficient orange garden nitrogen fixation method based on waste compost and vicia villosa cooperation
By using the acetylene reduction method to detect ethylene production and variance analysis, combined with dynamic adjustments to vetch planting intervals, microbial inoculum dosage, and compost particle size, the blindness in nitrogen fixation performance testing and the inaccuracy of adjustment strategies in existing technologies were resolved, thus achieving efficient nitrogen fixation in orange orchards.

AI Technical Summary
In the existing technology, nitrogen fixation performance testing relies on static indicators such as soil total nitrogen and available nitrogen, which cannot reflect the activity of microbial nitrogenase in real time. As a result, when the nitrogen fixation effect does not meet the standard, it is difficult to distinguish whether it is a compost quality problem or a green manure cultivation problem. The adjustment strategy is blind and the cycle is long.
The acetylene reduction method was used to detect the ethylene production in soil samples. By analyzing the mean and variance of the ethylene production, the nitrogenase activity and nitrogen fixation intensity were accurately reflected. Combined with the dynamic adjustment of vetch planting interval, microbial inoculum dosage, crushing particle size and inoculant dosage, the nitrogen fixation capacity could be accurately diagnosed and adjusted.
It improves the accuracy of nitrogen fixation capacity diagnosis and the targeted nature of adjustments, reduces the adjustment cycle, improves nitrogen fixation efficiency, and avoids resource waste and overuse of chemical nitrogen fertilizers.
