玉米涝渍胁迫的水分产量关系试验研究
Experimental Study of Relationship between Water and Yield of Maize
摘要
Abstract
Abstract. Experimental study on combined controlling of surface and subsurface water logging in undisturbed test pits where maize planted was carried out. The study results showed that the maize yield decreased, meanwhile, the height of maize and the day of tasseling and silking were respectively inhibited and delayed for Seedling and jointing stage water logging. The susceptibility in four phases of maize was ranked as follows: Seedling)jointing)tasseling-silking)maturity. There were good linear relations between the relative yield of maize and the SDI30, SDI50, SDI80, as well as the relationship between SDI50 and field was significant correlation. The new water production functions were reasonable and feasible. Composite index from water logging such as SFEW50 and SDI50 could be helpful for drainage system design and for operation & maintenance of the drainage farmland project in Huaibei plain.关键词
