The invention relates to the field of medicinal fertilizers and provides a green ecological medicinal
fertilizer for soybeans and a preparation method of the green ecological medicinal
fertilizer. According to a formula, the green ecological medicinal
fertilizer for soybeans is prepared from the following raw materials in parts by weight: 2-10 parts of walnut leaves, 4-10 parts of apple leaves, 10-20 parts of birch leaves and 10-30 parts of soybean straws. The preparation method comprises the concrete steps of (a) cleaning the leaves in a NaCl water solution according to the weight part, and airing; (b) uniformly stirring the aired leaves and the soybean straws (ground until the
diameter is up to 0.5-1cm), diluting 1 part of prepared vinegar
yeast by using 100kg of cold boiled water, and then, uniformly spraying the vinegar
yeast; (c) covering and sealing a
compost by using a
plastic film, and then, wrapping the
compost by using the straws until the
compost is fermented to be mature; and (d) preparing the vinegar
yeast, namely, culturing 1 part of the vinegar yeast in a culture medium prepared according to the formula: 3-4ml of edible
alcohol, 0.4g of glucose, 1g of yeast extracts, 1.5g of
calcium carbonate, 1.5g of
agar and 100g of water at the temperature of 30 DEG C for 2 days, and then, storing in a refrigerator (4 DEG C). By using the green ecological medicinal fertilizer for soybeans, the aims of turning waste into wealth and combining a fertilizer and a
medicine are achieved, and nutritive elements required by growth of soybeans can be comprehensively provided.
