Developing water-saving irrigation regimes has important practical significance not only in alleviating the crucial water shortage,but also in controlling soil salinization for the protected cultivation in eastern China.A field study with six treatments was conducted to evaluate the effects of different irrigation regimes with subdrainage systems on the soil nitrate nitrogen,salinity and moisture,also evaluate the effects on tomato growth,fruit yield and irrigation water use efficiency(IWUE).The treatments were distinguished by three different irrigation amounts of 310 mm,360 mm and 410 mm,and two irrigation frequencies of 7 and 11 *** showed that the irrigation amount had significant effects on the soil NO_(3)^(-)-N and electric conductivity(EC).A positive correlation was detected between soil NO_(3)^(-)-N(x)and EC(y)at 0-20 m depth after harvest,with a linear equation of y=*** volumetric moisture at 0.10 m and 0.20 m depth was increased as the irrigation amount ***,a higher amount of irrigation increased the fruit yield but reduced the IWUE of *** was also found that smaller irrigation amounts combined with frequent intervals could increase fruit yield and ***,the fruit quality of tomato had a significant(p<0.05)negative correlation with irrigation ***,the parameters of irrigation regime including the irrigation amount and intervals should be considered comprehensively in order to find a compromise between salinity control and irrigation water use efficiency improvement.

Corn Leaf Water Retention as Affected by OrganicFertilizations and Effective Microbes Applications

引用

Pedosphere 1998年第1期8卷 1-8页

作者： xu huilian N. AJIKI WANG XIAOJU C. SAKAKIBARA and H. UMEMURA (International Nature Farming Research Center, Hata-machi, Nagano 390-14 (Japan)) International Nature Farming Research Center Hata-machi Nagano 390-14 Japan

Effects of organic fertilizers and effective microbes on leaf water retention of sweet corn (Zea mays L. ***-Bantam) were studied. Sweet corns were grown with organic or chemical fertilizers with or without effective microbes (EM). A water retention curve was obtained by drying the excised leaves under a light of 500 μmol (m2·s)-1. The curve shows two distinct phases. The initial steep slope indicates the water loss speed by stomatal transpiration (Est) and the gentle slope of the second phase indicates water loss speed by cuticular transpiration (Ecu). Both Est and Ecu were lower for leaves of plants grown with organic materials than for those with chemical fertilizers. Addition of EM to both organic and chemical fertilizers decreased Est but showed no effect on Ecu. The water retention ability of the excised leaves was proportional to photosynthetic maintenance ability under soil water deficit conditions as well as the solute concentration in leaves. The results suggested that organic fertilization and EM application increased water stress resistance both under in situ conditions and in excised leaves of sweet corn plants.
