The Influence of Fluctuated Soil Moisture on Growth Dynamic of Winter Wheat
The Influence of Fluctuated Soil Moisture on Growth Dynamic of Winter Wheat
摘要
Abstract
Glasshouse and laboratory tests were carried out in 1996 - 1998 using winter wheat cultivars Beinong 6 as materials. The growth dynamics of the whole-wheat plant were analysed under constant and fluctuated soil water condition. The results revealed that water stress made the starting time of crop greatest growth phase(STCGGP) in advance, prolonged crop greatest growth phase(CGGP), decreased the rate of crop greatest growth (CGGR or CGRm), and as a result, the rate of dry matter accumulation was reduced and the growth of the crop was slowed down. Rewatering delayed STCGGP, shortened CGGP, increased CGGR, thus,the rate of dry matter accumulation had been boosted and the growth of the crop was accelerated. The growth rate, dry matter weight and grains yield of winter wheat were almost equal to the well-watered controls if they were rewatered under the condition of moderate water stress during the jointing stage.关键词
