The invention relates to a biodegradable plastic film mulching planting method for organic rice. The method comprises the following steps of 1, seedling raising; 2, land leveling and preparation; 3, rice seedling transplanting; 4, water and fertilizer management; 5, weeding. The biodegradable plastic film mulching planting method for the organic rice has the advantages that the ground temperaturecan be increased, and the effective accumulative temperature is increased; the water-saving effect is obvious; various weeds can be killed by using the high temperature under plastic films without anyweed killers, and the high temperature under the plastic films can promote fermentative decomposition of organic manure in soil, the long-acting effect of the organic manure is exerted, and root development is promoted; production and income are increased, and the benefits are obvious. The organic rice yield per unit area can reach 550 kg, the procurement price of per kg of the organic rice can be higher 1.7-1.8 Yuan than the market price, the income per mu can reach 2800 Yuan, and the net income can reach 1900 Yuan.
