The invention discloses a double-cropping no-tillage seedling-throwing straw-to-farmland rice high-yield and high-efficiency production method which comprises the following steps of: a, cleaning a ditch and draining in winter, to be specific, ditching to let rice field leakage water go in winter so as to keep no accumulated water on a field surface before seedling throwing of early season rice; b, performing no-tillage planting and management on the early season rice, to be specific, growing seedlings of the early season rice by using a plastic soft tray, throwing the seedlings when the seedlings have 3.5-4.5 leaves, and wetting as well as irrigating the early season rice in the whole process; c, utilizing straws of the early season rice, to be specific, remaining high stubbles while harvesting the early season rice; d, performing no-tillage planting and management on late rice, to be specific, growing seedlings of the late rice by using the plastic soft tray or growing the seedlings in a dry manner without the tray, and adopting an irrigation mode of irrigating shallowly and exposing the field; e, utilizing the straws of the late rice, to be specific, remaining high stubbles while harvesting the late rice. The double-cropping no-tillage seedling-throwing straw-to-farmland rice high-yield and high-efficiency production method solves the problems of great tillage labor intensity, slow nutrient transformation, easy runt seedlings and no growth of the rice, late maturity, low yield and the like of soil gleyization and secondary soil gleyization rice production in south rice areas, is a matured production technology for improving low-yield rice fields in soil gleyization and secondary soil gleyization, and achieves great application and generalization values in the aspects of reducing agricultural production cost, improving soil organic matters, decreasing fertilizer applying amount, increasing rice yield, improving moisture and fertility preservation performances of soil and the like.
