Foliar bacterial fertilizer for solanaceae fruits and vegetables and monocotyledonous crops as well as preparation method and application thereof

Abstract

The invention creatively provides a foliar bacterial fertilizer for solanaceae fruits and vegetables and monocotyledonous crops and a preparation method thereof. The foliar bacterial fertilizer is prepared by adopting a new strain Rhodoblastus acidophilus PNSB-AC CGMCC No. 20881 with good fermentation performance through a specific fermentation method and specific components. The foliar bacterial fertilizer can effectively promote foliage spray application of tomatoes, peppers, strawberries, wheat, millet and rice, can significantly improve the crop quality, solves the problem of yield reduction caused by insufficient illumination, and has wide development value in the field of agricultural planting.

AI Technical Summary

Problems solved by technology

[0002] In agricultural planting, in order to promote the growth of crops, chemical fertilizers are often used for nutrient supplementation, but a large amount of chemical fertilizers can easily cause soil compaction, resulting in a decrease in the yield of agricultural plants

The utilization rate of chemical fertilizers is low. Because nitrogen fertilizers are volatile and lost, the excessive use of chemical fertilizers will greatly reduce the quality of vegetables and fruits.

The general composition of chemical fertilizers is relatively simple, so long-term use of chemical fertilizers will inevitably lead to a single nutrient in the soil, which will easily cause crop nutrition imbalance, resulting in a decline in crop quality

At the same time, it will also lead to excessive nitrate content in vegetables, a large number of deaths of beneficial bacteria and earthworms in the soil, and long-term inefficient application of chemical fertilizers, often resulting in excessive accumulation of certain elements in the soil, changes in soil physical and chemical properties, and environmental pollution.
