NOVELTY - Cultivating rice comprises e.g. selecting rice cultivating area, selecting rice seedling and cultivating seedling in rice field, providing organic fertilizer comprising fermentation livestock excrement, molasses powder, fermented cattle bone meal, zeolite powder and spray bacteria, applying seedling base fertilizer and organic fertilizer in 80-250 kg/acre, close planting seedling in rice field, using the organic fertilizer as additional fertilizer in seedling tillering period, applying according to 8-25 kg/acre, or diluting organic fertilizer using water and spraying on the seedlings.    USE - The method is useful for cultivating rice (claimed).    ADVANTAGE - The method uses organic fertilizer to improve soil nutrients; avoids soil degradation, soil compaction, and reduction of beneficial organism; can improve the quality of the crop; increases crop (rice) calcium content, and agricultural product nutrition; improves ecological environment; and utilizes easily available raw material. The fermentation method is simple and easy to operate, and reduces the cost.    DETAILED DESCRIPTION - Cultivating rice comprises (i) selecting suitable rice cultivating area, selecting rice seedling in the seedling period, and cultivating seedling in rice field, (ii) cultivating seedling and providing seedling required organic fertilizer, where the organic fertilizer comprises 46-60 wt.% fermentation livestock excrement, 15-30 wt.% molasses powder, 5-15 wt.% fermented cattle bone meal, 3-10 wt.% zeolite powder and 0.5-1.6 wt.% spray bacteria, where the mass percent of each component is not less than 100%, where the fermentation of livestock excrement comprises collecting livestock excrement, mixing livestock excrement and organic matter powder according to the volume ratio of 1:(0.8-1.4), adding fermenting animal stool liquid according to the mass ratio of 0.4-1%, and carrying out bulk stacking fermentation, where the fermentation product central temperature is 55-65 degrees C, turning once, and continuously fermenting for many times until the fermentation product does not have peculiar smell, completing the fermentation, where in the fermentation process, the moisture content is controlled at 40-45%; the fermentation cattle bone meal is obtained by specific fermentation method, same as livestock and poultry excrement fermentation method, and (iii) seedling field fertilizer management: applying seedling base fertilizer and organic fertilizer in 80-250 kg/acre, close planting seedling in rice field, using the organic fertilizer as additional fertilizer in seedling tillering period, applying according to 8-25 kg/acre, throwing the organic fertilizer 8-25 kg/acre 10 days before, or diluting the organic fertilizer using water according to ratio of 1:(300-800) and spraying on the seedlings so that the whole blade is covered according to the standards, spraying for every 8-12 days, spraying for 3-5 times.
