Composite microbial fertilizer and preparation method thereof

Abstract

The invention discloses a composite microbial fertilizer and a preparation method thereof. The composite microbial fertilizer is composed of organic matters, nitrogen, phosphorus, potassium, functional microbes, rooting and seedling strengthening agent, polypeptide amino acids, secondary and minor elements, newly planted eucalyptus soil activating enzyme and a water-retaining and drought-resisting agent. The composite microbial fertilizer contains more than 40% of organic matters, 10% of humic acid, 3% of amino acids, 20% of nitrogen+phosphorus+potassium elements, more than 10% of secondary elements (calcium, magnesium and sulfur), 2% of minor elements (silicon, boron, zinc, manganese, copper, iron and molybdenum), and more than 20 million / g of complex functional bacterium and multiple enzymes. The preparation method comprises the following steps: fermenting before production, performing by complexing, rotting the organic matters, carrying out innocent treatment, weighing according to the optimal parts by weight, mixing and bagging. The composite microbial fertilizer improves the soil properties, increases the sugar degree by 2-3 degrees, is ecological and environment-friendly, and is capable of enhancing the soil productivity, increasing the soil nutrients and enhancing the bioactivity of the soil; and the disease prevention ratio is up to 70%, and the absorption and utilization ratio is up to 80%.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] As early as the twentieth century, national leaders put forward the strategic policy of biotechnology to solve agricultural problems. 1. Deng Xiaoping: The fundamental way out of China's agriculture depends on bioengineering and cutting-edge technology. 2. Jiang Zemin: The development of high and new technologies marked by biotechnology is the key to advancing the new revolution in agricultural science and technology. 3. Wen Jiabao: We must continue to develop new types of fertilizers that are compound, highly efficient and environmentally friendly to meet the needs of developing high-efficiency agriculture and pollution-free green agriculture. [0003] Definition of compound microbial fertilizer: compound microbial fertilizer refers to the combination of sp...
