The invention provides a planting method for organic rice. The method utilizes primary products produced by digestion of crop stalks, such as a plant growth substrate, a compound fertilizer and fiberbundles to manufacture a fertilizer fiber field membrane and a composite substrate template which are specially required by planting of the organic rice through fine preparation and deep processing production, the composite substrate template is utilized when rice seedlings are cultivated, the input costs are low, the seedlings can be raised in advance by 3-5 days, the method is soilless, has no pests or diseases, saves work and labor, and guarantees farming seasons, a pesticide does not need spraying in the process, and the cultivated seedlings are robust and have high quality; and when the rice seedlings are transplanted, the fertilizer fiber field membrane is combined, so that the rice seedlings can be saved, and the layout is reasonable. The use of the fertilizer fiber field membrane can not only block sunlight, inhibit weeds, and gradually reinforce ventilation functions, but also have functions of adjusting a temperature, preventing water and soil loss, preserving soil moisture,and cultivating land fertility, the field membrane can be degraded on schedule, and the product has no primary or secondary pollution. The planting method provided by the invention realizes all-element harmless and comprehensive development of the crop stalks, provides a pathway of fully recycling the crop stalks, and is very energy-saving and environmentally-friendly.
