A rice ridge-type plant-hole position-setting cultivation method, relating to a rice cultivation method and solving the technical problem of current rice cultivation land having low yields. The present rice ridge-type plant-hole position-setting cultivation method is the product of photosynthetic physics research and photosynthetic chemistry applied research in regard to the photosynthetic efficiency of rice growth, and can achieve, according to economic yields, a calculated efficiency of the ability of rice photosynthesis to utilize solar energy of 0.7%~1.5% per 1hm2. For seedlings using a rice vegetative body early-fertility single plant-hole position-setting cultivation method, short maturation time and medium maturation time rice varieties achieve stage-two tillers, and long maturation time varieties achieve stage-three tillers. For rice fields using a rice ridge-type plant-hole position-setting cultivation method, rice achieves a 100% tiller rate of 100% tillering ability, early maturation time varieties achieve stage-four tillers, medium maturation time varieties achieve stage-five tillers and late maturation time varieties achieve stage-six tillers. The number of tillering plants is controlled, and the vegetative growth period is converted to a reproductive growth period in an early stage for young ears to differentiate into large ears. The range of increased yield per mu for early maturation time rice varieties is 700kg〜1300kg, for medium maturation time rice varieties is 800kg〜1400kg, and for late maturation time rice varieties is 900kg〜1500kg. |
