The invention discloses a nutritional additive for improving water and soil in the
seedling stage. The nutritional additive is composed of the following components in parts by weight: 24 to 26 parts of
bentonite, 21 to 22 parts of brown
sugar, 4 to 5 parts of critic acid, 10 to 12 parts of
phosphor nitrate fertilizer, 22 to 24 parts of soybean
powder, 23 to 26 parts of
rapeseed cake
powder, 6 to 8 parts of
ferrous sulfate, 42 to 45 parts of
volcanic rock, 12 to 16 parts of aged tea, 63 to 67 parts of waste
crop straws, 15 to 20 parts of
threonine mother liquor, 3 to 5 parts of composite
fungal hyphae, and a proper amount of water. The porous structure, which is obtained by mixing
fungus dregs and
bentonite, of the nutritional additive can improve the
water content and
water holding capacity of soil for breeding seedlings; moreover, the
irrigation amount in the period stage can be reduced, the root will not be destroyed by
excess water, the organic substances in the
fungus dregs can cooperate with the chelating liquid to improve the pH value of soil, at the same time, the organic microbe number and organic
substance content of soil are greatly increased, and thus the
crop growth in the
seedling stage can be promoted.
