| 摘 要： | 大田栽培条件下,以"花育22"和"花育20"品种为材料,以不施肥为对照,设控释肥675 kg hm-2、控释肥506 kg hm-2和普通肥料3个处理,研究了控释肥料对不同品种花生叶片衰老的影响。结果表明:相比普通肥料,控释肥可以提高花生生育后期叶面积系数、叶绿素含量以及有关保护酶的活性,降低叶片膜脂过氧化程度,有效延缓花生的衰老速率,提高生育后期光合产物积累,为花生产量的提高奠定基础。因此,控释肥是花生较为理想的肥料。

| Abstract: | Field experiments were carried out to study the effects of controlled-release fertilizers on leaf physiology of different peanut varieties,‘Huayu 22’and ‘Huayu 20’.There were four treatments: controlled-release fertilizer 675 kg hm-2(T1),controlled-release fertilizer 506 kg hm-2(T2),ordinary fertilizer(T3) and without fertilization(T4).Controlled-release fertilizers could improve LAI,Chl as well as activities of SOD,POD and CAT decrease the Lipid peroxidation of leaf,delay the senescence and enhance the accumulation of photosynthetic product during the later growing stage of peanut.Relative to T3 treatment,controlled-release fertilizer treatments were better on delaying plant senescence.These results implied that controlled-release fertilizers could contribute the delaying of the leave senescence and the accumulation of photosynthetic product during the later growing stage of peanut plant,and were suitable for peanut growth and development. |
