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。
Under the condition of field cultivation, using “Huayu 22” and “Huayu 20” as materials, with no fertilization as CK, the control release fertilizer was 675 kg hm-2 and the controlled release fertilizer was 506 kg hm-2 and The effects of controlled release fertilizers on leaf senescence of different varieties of peanut were studied. The results showed that compared with common fertilizer, the controlled release fertilizer could increase the LAI, chlorophyll content and the activities of protective enzymes in the late growth stage of peanut, reduce the lipid peroxidation level of peanut, effectively reduce the peanut aging rate and increase the accumulation of photosynthetic products , Laying the foundation for the improvement of peanut production. Therefore, controlled release fertilizer is an ideal fertilizer for peanuts.
