摘要
１９９３－１９９４年在碳酸盐黑钙土上进行了有机肥、化肥和有机无机配合施用的盆栽试验。在大豆生育期间人工模拟旱境条件下测定了与大豆抗旱性有关的大豆叶片细胞膜透性、过氧化氢酶活性、内源激素脱落酸含量和茎叶组织超微结构等项目。结果表明，在干旱条件下，有机肥能减轻旱情，降低大豆植株脱落酸含量和叶片细胞膜透性，提高叶片过氧化氢酶活性，减少细胞膜损伤，延缓大豆叶片衰老及叶片栅栏组织细胞外壁明显增厚。回归相关测定结果表明，干旱条件下大豆叶片细胞透性越小，植株叶片的过氧化氢酶活性越大，二者呈显著的负相关；
The experiment of applying organic fertilizer, chemical fertilizer and the both to calcareous blade soil in which organic content was very low was carried out from 1993 to 1994. The conductivity of osmotic electrolyte and the catalase activity and the content of abscisic acid of endo-hormone, as wall as ultrastructure of palisade tissue and xylem were determinded under the condition of artifical simulated arid regime at different growth stages of soybean. Results indicated that under the condition of drought, organic fertilizer could relax ravages of drought, reduce the content of abscisic acid in soybean plant and the conductivity of osmotic electrolyte of leaf blade, raise the catalase activity of leaf blade, decrease the injury of cell envelope, and avail to delay senesence of soybean leaf blade, and cell wall of palisade tissue of leaf was increased in thick ness.The test result of regression correlation indicated that,under the condition of drought, the lower the conductivity of osmotic electolyte of leaf blade, the higher the catalase activity of palnt's leaf blade is, ralationship between these two is remarkably negative in correlation. Relationship between the content of abscisic acid of endo-hormone of leaf blade and the conductivity of osmotic electrolyte is possitive in correlation.
