Problems solved by technology

The special fertilizers for blueberries in the above reports do not fully consider the comprehensive needs of blueberries for soil, and it is difficult to ensure the sustainable planting of blueberry crops. After long-term planting, it is easy to appear yellow and white between the veins of strawberries, the newly grown leaflets turn white, and the edge of the leaves is necrotic. Or the yellowing of small leaves (only the veins are green), the browning and necrosis of the edge of the leaves and the veins, etc., seriously affect the formation of chlorophyll in strawberry plants, and also affect the photosynthesis of plants. In addition, it is also prone to the occurrence of various diseases of crops. Decreased fruit weight and yield

Abstract

The invention discloses a preparation method and application of a trichoderma bio-organic fertilizer special for blueberries. The specific preparation process of the fertilizer comprises the followingsteps: (1) preparing acidolysis amino acid; (2) preparing acidolysis amino acid chelated iron; (3) preparing a trichoderma solid strain; (4) adding amino acid chelated iron into a traditional Chinesemedicine residue source decomposed compost for neutralization and after-ripening; and (5) preparing the special trichoderma bio-organic fertilizer for blueberries. The trichoderma bio-organic fertilizer special for blueberries contains 1.0-1.5% of amino acid, 1-2% of ferrous sulfate, 2-3% of nitrogen, 1-2% of phosphorus, 2-3% of potassium, 45-50% of organic matter and (1-5)*10<8> cfu / g of trichoderma spores, the water content mass ratio is lower than 30%, and the pH value is 5.5-6.5. The trichoderma bio-organic fertilizer special for blueberries has remarkable effects of improving yellowing of new blueberry leaves, promoting growth of blueberry root systems, increasing the yield of blueberries and improving the quality of blueberries.

Description

technical field [0001] The invention belongs to the field of biological technology, specifically relates to the technical field of intensive agricultural production, and more specifically relates to a preparation method and application of a special biological organic fertilizer for blueberries. Background technique [0002] Blueberries are rich in nutrients and have various health functions such as preventing brain nerve aging, anti-cancer, softening blood vessels, and enhancing human immunity. The blueberry root system is slender and has no root hairs. The root system is concentrated in the soil layer rich in organic matter or in the covering layer on the soil surface, which is a shallow root system plant. Blueberry is a kind of oligotrophic acid-loving plant. The demand for mineral nutrients such as nitrogen, phosphorus and potassium is far less than that of other berry plants. It has higher requirements for soil organic matter content, and is suitable for growing on soil ...
