摘　　要：以盐丰47为试验材料,采用开放式红外增温技术来模拟气候变暖对水稻产量及其构成因素的影响。结果表明:花后增温虽然能够促进叶茎鞘储藏物质向籽粒转运,但由于同时降低了叶片的光合能力,综合表现来看,花后增温不利于水稻的灌浆结实;花后增温使水稻干物质生产量减少,千粒重及结实率下降,对水稻产量具有显著的降低作用。The test is to explore the effects of free air temperature enhancement on rice yield and its composing factors.The result indicated that free air controlled condition after anthesis although can promote storage reserves of stem-sheath from leaves to grains,but at the same time it reduce leaf photosynthetic capacity,according comprehensive assessment,free air controlled condition after anthesis against filling and seedset,it reduced dry matter productions of rice,thousand seed weight and setting percentage,so it could remarkably reduce the yield of rice.
