摘要: 为明确水稻不同生育时期的农艺性状及产量性状受节水处理的影响,以“津原E28”、“津稻417”为试验材料,通过人工控制水分灌溉量,在水稻不同生育时期进行节水处理,探究不同时期节水后水稻农艺性状及产量性状的变化规律。结果表明:在水稻生长发育的各时期节水均会在不同程度上影响水稻的产量,主要制约因素为穗数和千粒重,各处理间产量降低幅度为14%~39%、12%~27%。节水处理对穗数、每穗粒数、杆长、穗长、实粒率和千粒重的影响均达到0.1%水平上的显著差异。拔节期至孕穗期节水,水稻每穗粒数、千粒重、产量下降最为明显;返青至分蘖期的节水处理,水稻的分蘖数和有效穗数均最低;出穗至灌浆期的节水处理实粒率最低。

Abstract: In order to research the effect of water saving treatment on rice agronomic traits and yield during different growth stages, agronomic traits and yield using 2 rice varieties(Jingyuan E28 and Jingdao 417)were studied under water saving treatment by rice during different growth stages to clear changes of agronomic traits and yield in rice. The results showed that the various effects of water saving treatments on yield during different growth stages and spike number and 1000-grain weight was the most limited factor. The reduce the rate of yield was 14%-39%, 12%-27%, respectively. Spike number, kernels per spike, stem length, spike length, the solid grain number and 1000-grain weight of water saving treatment was significant. The decline of kernels per spike, 1000-grain weight and yield of rice was obvious in jointing and booting. The rice panicles and grains panicles of water saving treatment was the lowest from green to tillering stage. The solid grain number of water saving treatment was the lowest from out of the ear to tillering stage.
