The invention discloses a preparation method for
organic fertilizer for preventing and treating secondary salinization of a
solar greenhouse vegetable field. The preparation method comprises the following steps: (1), mixing
cow dung or a mixture of the
cow dung with one or more of goat
manure,
chicken manure, pig
manure, straws and waste tobacco shreds according to the volume ratio of 1:1 and fermenting, thereby obtaining a material A; (2), preparing
earthworm cast after
cow dung is fermented; (3), crushing
crop straws, adding the crushed straws to
chicken manure or pig
manure, and
enzyme microorganism, mixing uniformly, building stacks and fermenting, thereby obtaining a material D; (4), mixing the materials A, C and D to obtain a material E; (5), mixing the material E,
calcium cyanamide,
diammonium phosphate,
zinc sulfate and
sodium borate, thereby obtaining finished products
organic fertilizer. According to the preparation method for the
organic fertilizer for preventing and treating the secondary salinization of the
solar greenhouse vegetable field, wastes of
agriculture and
animal husbandry industries are utilized as main materials and match natural antibacterial materials, such as
lime nitrogen, in accompany with secondary and trace elements, such as
calcium,
boron and
zinc, so as to solve problems of vegetable
wilting and soil harmful
bacteria caused by the salinization of the
solar greenhouse vegetable field. Compared with application of common
fertilizer, application of the prepared organic
fertilizer has the advantages that the fertilization costs are reduced and the yield and quality of vegetables are improved.
