Abstract
To determine feasible irrigation stage and amount for super-high-yield land and excavate the yield potential of super-high-yield wheat,the effects of irrigation stage and amount on the dynamic changes of soluble sugar and sucrose in flag leaf and grain,and yield of super-high-yield wheat at filling stage were evaluated in super-high-yield land of Jinhai seed limited company.The results indicated that irrigation increased the metabolic activity of soluble sugar and sucrose of super-high-yield wheat at grain filling stage compared with the control,and the grain yield of super-high-yield wheat significantly increased.In the 2009-2010 growing season with rainfall of 291.7 mm,the treatment T5 was irrigated 60 mm at wintering,jointing and filling stage respectively,of which the contents of soluble sugar and sucrose were the highest and the transformation of soluble sugar and sucrose was the most thorough,and its yield was supreme up to super-high-yield level(9 923.58 kg·hm-2).Increasing irrigation amount(T7 and T8),the metabolic activity of soluble sugar and sucrose,grains per spike,1000-grain weight and water use efficiency decreased significantly,which leaded to yield reduction.So under the experimental conditions,irrigated 60 mm at wintering,jointing and filling stage respectively was the feasible irrigation scheme to super-high-yield land.
