Double-source potassium fulvate bacterial fertilizer and production method thereof

Abstract

The invention belongs to the technical field of microbial fertilizers, and relates to a double-source potassium fulvate bacterial fertilizer and a production method thereof, and the production method is characterized by comprising the following steps: S1, uniformly mixing compound microorganisms, beneficial nutrients and water according to a ratio of 1%-2%: 15%-30%: 7%-10%, and carrying out aerobic fermentation at the fermentation temperature of 30 DEG C for 24-72 hours to obtain solid compound bacteria; and S2, performing secondary uniform compounding on the obtained solid compound bacteria, 48%-68% of double-source potassium fulvic acid, 9%-12% of medium trace elements, protein and the like. The bacterial fertilizer researched and developed by the invention is rich in mineral source potassium fulvic acid, plant source potassium fulvic acid and medium trace elements, and double sources are integrated and comprehensively utilized. Meanwhile, the fertilizer also contains various beneficial bacteria, improves the physiological function of soil, can activate soil, improve soil organic matters, promote root growth and increase nutrient absorption and utilization of crops, achieves the purposes of increasing production and income and improving crop quality, and is a guarantee for producing green products.

Description

technical field

[0001] The invention belongs to the technical field of microbial bacterial fertilizer, and in particular relates to a dual-source potassium fulvic acid bacterial fertilizer and a production method thereof. Background technique

[0002] Since the founding of the People's Republic of China more than 70 years ago, my country has always regarded the development of the chemical fertilizer industry as the top priority of the basic national policy, so my country's chemical fertilizer industry has developed rapidly. Over the past few decades, my country's total grain output has increased substantially with the increase in the amount of chemical fertilizers applied, which has basically met the needs of population growth. , the phenomenon of diminishing returns. The long-term excessive use of a single chemical fertilizer has a large amount of use and its utilization rate is 20 percentage points lower than that of developed countries. This not only caused a huge waste ...
