Fertilizer additive for promoting fruit precocity and improving fruit storability

The invention provides a fertilizer additive for promoting the fruit precocity and improving the fruit storability. The fertilizer additive for promoting the fruit precocity and improving the fruit storability is prepared from the following components by mass: 25-35 parts of bean pulp and earthworm fermentation liquor, 30-45 parts of biotechnology fulvic acid and 0.3-0.8 part of chitosan oligosaccharide; water is added to the raw materials in parts by mass for aerobic fermentation, and an obtained product is then subjected to anaerobic fermentation to obtain fermentation liquor which is the fertilizer additive. The fertilizer additive can promote fruit growth, hormone ripening conducted on fruits is avoided, the soil physicochemical property is improved, and a fruit storage period is prolonged. 本发明提供种促进果品早熟和提高果品耐贮性的肥料添加剂，包括以下质量组份：豆泊蚯蚓发酵液25~35份，生化黄腐酸30~45份，壳寡糖0.3~0.8份，将上述质量份数的原料加水进行好氧发酵，所得产物再经过厌氧发酵所得的发酵液为本发明所述的肥料添加剂。本发明能够促进果品生长，对果品无激素催熟，改良土壤理化性质，延长果品贮藏期。
