NOVELTY - Fertilizing for organic tomato cultivation comprises taking deep gardening soil, shallot garlic vegetable field soil or large field soil, non-rotten chicken manure or pig manure and prepared horse manure or straw, layered composting, covering, sealing and fermenting, turning, and fermenting, soaking seeds, seeding, covering, watering to prevent the earth temperature from decreasing and air humidity from increasing, mixing cow manure with sheep manure, applying farmyard manure, ploughing, applying cake fertilizer as base fertilizer, ripening the fruit, and managing cultivation operations.    USE - The method is useful in fertilizing for organic tomato cultivation (claimed).    ADVANTAGE - The method: can increase yield of organic tomato; increases sugar-acid ratio and the content of vitamin C in tomato; reduces nitrate and nitrite content in fruit; utilizes raw material sources; and has low production cost.    DETAILED DESCRIPTION - Fertilizing for organic tomato cultivation comprises (i) taking deep gardening soil, 4 pts. wt. shallot garlic vegetable field soil or large field soil, 3 pts. wt. non-rotten chicken manure or pig manure, 3 pts. wt. prepared horse manure or straw from bottom to top according to the soil, composting chicken manure or pig manure, horse dung or straw, again repeating for one time, finally soil layering, where thickness is 15-20 cm, when the horse manure or straw are penetrated into water, stacking the plastic material film, sealing with a cover, after 15 days, at natural temperature, covering, turning once, stirring up and down, if deposited water content is less than 50%, then adding water to make the water content to reach up to 70-80%, using a plastic film for sealing the cover, carrying out fermentation for 15-20 days, sieving, mixing uniformly, seed processing by using clean water of 55 degrees C to soak for about 20 minutes, stirring for 2 times, taking out, draining seeds, where the seeding amount is 20-30 g/mu, the thickness is 3 cm, after seeding, covering the soil up to 1 cm, removing the film breed, and planting after pouring water; (ii) water management: watering 4-5 days for slowly seedling, first starting to water when first spike fruit has length to diameter of 4 cm, pouring water once for every 15-20 days when the temperature is lower than 15 degrees C, pouring water once for every 10-15 days when the temperature is 15-25 degrees C, pouring water once for every 7-10 days when the temperature is more than 25 degrees C, adding water once, watering for 1-2 times during late December to late January period, preventing the earth temperature from decreasing and the air humidity from increasing, increasing watering time during fruiting period to achieve required plant and fruit growth, when soil contains adequate water, i.e., water content between 20-25%; (iii) fertilizing with cow dung and sheep manure according to weight ratio of 1:1, mixing uniformly, applying 15 m3 farmyard manure to each acre of earth, then ploughing, applying 200 kg cake fertilizer as a base fertilizer before furrowing, applying 10 kg organic fertilizer fish protein in a flushing manner for the first time when the diameters of tomato fruits are 4 cm, and applying once every 20 days until harvesting is ended; and (iv) topping 3-4 spike fruits, using a fertility agent on No.2 dip flowers, using ethylene for ripening the lower portion of fruit, and managing the cultivation operations during sunny day.
