摘 要: | 为探讨秸秆不同处理方式对玉米生长发育特征的影响,将破碎秸秆、腐熟秸秆和秸秆炭添加到模拟施肥的土壤中,研究了秸秆还田后对玉米生长发育特征的影响。结果表明,在不同施肥模式下,秸秆不同处理方式对玉米株高促进作用的顺序为:2.0%秸秆炭1.0%秸秆炭0.5%秸秆炭腐熟秸秆破碎秸秆;秸秆炭处理均能提高玉米的叶宽。在传统施肥模式和测土配方施肥模式下,单穗籽粒重提高5%~7%;秸秆炭处理都能提高玉米产量(P0.05)。

Abstract: | In order to study corn development of soil in different treatments of straw, the crushed straw, rotten straw and straw charcoal added to simulated fertilization in soil, the effect of straw returning on soil corn development was studied. The results show that under different fertilization methods, the effects of differently processed straws on maize height, from greatest to least, were as follows: 2.0% straw charcoal > 1.0% straw charcoal > 0.5% straw charcoal > decomposition straw > crushed straw; straw charcoals were all able to increase corn leaf width. Using traditional fertilization methods and soil testing fertilization methods showed a 5-7% improvement. Straw charcoals were all able to improve corn productivity (p< 0.05). |
