The invention provides nutritional soil for cultivating eggplant seedlings and a preparation method of the nutritional soil. The preparation method comprises the following steps: firstly, selecting fermented
cow dung, fermented rice
husk chicken manure and composted
pleurotus ostreatus residues and other raw materials which are commonly used in
daily production according to growth demands of the eggplant
seedling stage; secondly, preparing special nutritional soil for cultivating the eggplant seedlings by multiple formulation screening experiments. The nutritional soil is economical and practical as well as is beneficial to growth of the eggplant seedlings; in addition, during the
seedling cultivation period for two months or longer, spraying of
fertilizer is not needed, and the eggplant seedlings vigorously grow; the nutritional soil is a better choice for cultivating the eggplant seedlings. At present, generally-applied cultivation matrixes in the world are
peat and rock
wool, but the two matrixes are expensive,
peat resources are unrenewable, and the rock
wool is non-degradable, therefore, all countries in the world are trying to study substitutes of the
peat and the rock
wool. At the same time, the fermented
cow dung, the fermented rice
husk chicken manure, the composted
pleurotus ostreatus residues and the like are used, so
livestock manure and agricultural wastes are enabled to be recycled, and replace the non-renewable peat, and further
resource conservation and environment friendliness are facilitated.
