NOVELTY - A special base fertilizer preparation method involves uniformly mixing fresh cow dung mannure, biological nitrogen-fixing bacteria, phosphate-solubilizing bacteria, potassium solubilizing bacteria, ammonification bacteria, yeast and actinomycetes, and fermenting the mixture. The resulting blend is added to sterilization deodorant followed by adding rapeseed cake recipe, rape straw, clean river mud and fermentation agent, mixing and fermenting. The fermented product is dried followed by adding zinc amino acid chelate, rooting powder and plant growth regulator and uniformly mixing.    USE - Method for preparing special base fertilizer for longjing tea trees.    ADVANTAGE - The method enables preparing fertilizer with rich organic matters and high bioactivity. The fertilizer is odorless, and is sterile and convenient to use. The fertilizer is easily absorbed by the roots of longjing tea trees after being applied, and improves drought resistance, disease resistance and insect resistance, pest resistance and immunity of trees.    DETAILED DESCRIPTION - A special base fertilizer preparation method involves uniformly mixing 30-32% fresh cow dung mannure, 0.1% biological nitrogen-fixing bacteria, 0.1% phosphate-solubilizing bacteria, 0.1% potassium solubilizing bacteria, 0.1% ammonification bacteria, 0.1% yeast and 0.1% actinomycetes in a fermentation tank, and fermenting the mixture in a sealed condition for 15-17 days. The resulting blend is added to 1% sterilization deodorant. 18-20% rapeseed cake recipe, 24% rape straw are 20% clean river mud are ground in a grinding mill, and the ground mixture and 1% fermentation agent are added to the fermentation tank followed by mixing, adding water and fermenting for 25-27 days in a sealed condition. The fermented product is taken out from the tank and dried such that the moisture content is reduced to less than 10%. 0.2% zinc amino acid chelate, 0.2% copper amino acid chelate, 0.3% humic acid chelated iron, 0.7% humic acid chelated calcium, 1% rooting powder and 1% plant growth regulator are uniformly mixed with fermented product to obtain fertilizer. An INDEPENDENT CLAIM is also included for method for applying special base fertilizer, which involves applying 10-15 kg special base fertilizer to submerged plant of longjing tea tree during early spring.
