苏打盐碱土控水栽培水稻生理指标与产量关系研究

针对松嫩平原盐渍土水稻种植地下水逐年减少的生态问题,节水种植水稻必将成为发展的趋势,灌水洗盐是盐碱地水稻种植的核心技术。为了减少模拟和大田的差异,于2011年在吉林省大安市进行大田试验,通过在返青期、分蘖期、抽穗期和灌浆期的不同生育时期进行节水处理,并在分蘖前期、分蘖后期、抽穗期和灌浆期进行生理指标的测定,以及成熟期的产量测定。结果表明:分蘖期控水处理的理论产值达到最大,极显著高于,显著高于处理1。节水增产高效率期在分蘖期。

Study on physiological character and yield on saline-sodicsoil of water-saving cultivation

Aiming at the ecological problem of groundwater decreasing at the songnen plains saline soil for rice cultivation year by year.Saving water for rice plant will become a tren of development,Saline irrigation to wash the salt was the core technology of rice cultivation.In order to reduce the differences between simulations and fields.In the different growth stages of turning green stage,tillering stage,booting stage and milk stage we made water treatment and in early tillering stage,after tillering stage,booting stage and milk stage we made physiological tracking measurements and determination in maturity stage.The result showed that the biggest biomass was in tillering stage,significantly higher than CK,significantly higher than treatment 1 and increasing yield in tillering stage.
