Preparation method of organic compound biological fertilizer special for peanuts

Abstract

The invention discloses a preparation method of an organic compound biological fertilizer special for peanuts. The method comprises the steps that crushed straw and cow dung serve as solid organic materials, 5%. of organic material decomposing agent with a specific decomposing effect and an appropriate amount of water are added and mixed with the organic materials, the water content is maintained to be about 60%, fermentation is conducted for 5 days to 10 days at natural outdoor temperature, and an initial fertilizer is formed through decomposing; an appropriate proportion of various nutrient elements are added and mixed with the fermented materials to be uniform, 4%. of growth promoting compound microbial inoculant special for the peanuts is added, mixing is conducted to be uniform, and the biological fertilizer is obtained. According to the preparation method of the organic compound biological fertilizer special for the peanuts, various disadvantages caused by pure application of chemical fertilizers, ordinary organic fertilizers, farmyard manure and pure microbial fertilizer are overcome, the growth features and demands on nutrients of the peanuts in all periods are fully combined, attention is paid to adjusting of the contradiction between nutrition growth and reproductive growth of the peanuts, and the organic compound biological fertilizer is suitable for peanut growth, efficient and excellent in quality and has a great application prospect in the aspect of peanut production and planting.

Description

technical field [0001] The invention relates to an organic composite biological fertilizer and a preparation method thereof, which is especially suitable for peanuts and belongs to the technical field of agricultural biological organic fertilizer preparation. Background technique [0002] At present, the annual use of chemical fertilizers in my country is about 130 million tons. The majority of farmers have always used chemical fertilizers. However, the disadvantages of long-term use of chemical fertilizers have followed, such as land compaction, chemical element residues, environmental pollution, etc. A series of problems surfaced. Chemical fertilizers can no longer meet the needs of sustainable development, let alone become the pillar of green agriculture. All countries are looking for countermeasures. Bio-organic fertilizer was born and became the second revolution of chemical fertilizer. Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertili...

Problems solved by technology

[0003] Peanuts are mostly planted in hilly gravel soils, plain alluvial sandy soils, and southern red-yellow soils. These soils have sandy textures, poor results, and low fertility. Simply applying chemical fertilizers can no longer meet the nutritional needs of peanuts. Bioorganic bacteria should be added. Fertilize the soil and improve the soil to obtain high-quality and high-yield
