NOVELTY - A soilless cultured tomatoes nutrient set comprises nutrition substrate, and nutrition fertilizer comprising fertilizer A and fertilizer B. The nutrition substrate comprises (pts.wt.) ginger plant (180-260), oil residue (50-100), tobacco residue (160-250), sawdust (180-250), microbial fermentation fungicide (3-8), calcium magnesium phosphate fertilizer (30-60), calcium nitrate (20-40), and vermiculite (150-230). The nutrition fertilizer A comprises (pts.wt.) urea (6-9) and potassium sulfate (1-4). The nutrition fertilizer B comprises (pts.wt.) urea (3-5) and potassium sulfate (5-7).    USE - Soilless cultured tomatoes nutrient set.    ADVANTAGE - The nutrient set provides substrate having good physical properties and containing phosphorus and calcium so that nutrients are not easily lost. The nutrition in the substrate interacts with the nutrition in the nutrition fertilizer so as to balance nutrition needed in different stages of the tomatoes.    DETAILED DESCRIPTION - A soilless cultured tomatoes nutrient set comprises nutrition substrate and nutrition fertilizer at mass ratio of 98.5-99.5:0.5-1.5. The nutrition fertilizer comprises nutrition fertilizer A and nutrition fertilizer B at mass ratio of 0.1-0.3:0.4-0.7. The nutrition substrate comprises (pts.wt.) ginger plant (180-260), oil residue (50-100), tobacco residue (160-250), sawdust (180-250), microbial fermentation fungicide (3-8), calcium magnesium phosphate fertilizer (30-60), calcium nitrate (20-40), and vermiculite (150-230). The nutrition fertilizer A comprises (pts.wt.) urea (6-9) and potassium sulfate (1-4). The nutrition fertilizer B comprises (pts.wt.) urea (3-5) and potassium sulfate (5-7). The nutrition substrate, the nutrition fertilizer A and the nutrition fertilizer B are packaged independently. The microbial fermentation fungicide is effective microorganisms (EM) composite fungicide. The calcium magnesium phosphate fertilizer contains 14-16 wt.% of phosphorus pentoxide. An INDEPENDENT CLAIM is included for preparation of the nutrient set, comprising:    (A) taking half amount of ginger plant, half amount of oil residue, half amount of tobacco residue, sawdust, and microbial fungicide, and uniformly mixing;    (B) regulating water content of the mixture to 55-65 wt.%, piling and fermenting by raising temperature to 55 degrees C for 5-8 days, then turning, and raising temperature to 50 degrees C for 3-6 days;    (C) adding rest amount of ginger plant, oil residue and tobacco residue, regulating water content to 55-60 wt.%, and continuously fermenting for 10-12 days, turning once to obtain fermented material;    (D) adding calcium magnesium phosphate fertilizer, calcium nitrate and vermiculite to the fermented material and uniformly mixing, standing for 6-8 hours, and airing or drying till water content is not greater than 20 wt.% to obtain nutrition substrate;    (E) weighing urea and potassium sulfate according to proportion of nutrition fertilizer A and uniformly mixing to obtain nutrition fertilizer A;    (F) weighing urea and potassium sulfate according to proportion of nutrition fertilizer B and uniformly mixing to obtain nutrition fertilizer B; and    (G) respectively packaging the nutrition substrate, the nutrition fertilizer A and the nutrition fertilizer B according to ratio, and then filling in a large bag.
