| 摘 要： | 设置漫灌常规施肥(CK)、微喷灌常规施肥(MC)以及微喷灌减肥20%(MR)3个处理,研究3种不同水肥处理对华北地区夏玉米营养生长和生殖生长以及最终产量的影响。结果表明,常规施肥量情况下,微喷灌能够促进玉米灌浆期生物量的积累,MC处理比CK处理显著提高9.58%,成熟期没有显著性差异;微喷灌减肥20%没有造成生物量积累的减少。常规施肥量情况下,微喷灌能够显著促进玉米子粒的灌浆速率,达最大灌浆速率时的天数比CK处理高1 d,灌浆速率最大时的生长量Wmax比CK高9.99%,灌浆活跃期比CK高7.20%;微喷灌减肥20%处理,与CK处理相比达最大灌浆速率时的天数比CK处理高1.60 d,灌浆速率最大时的生长量Wmax比CK高10.59%,灌浆活跃期比CK高14.83%,最大灌浆速率低于CK处理。MC处理玉米产量最高,分别比CK处理与MR处理提高6.70%与5.68%(P0.05);MR处理与CK处理没有显著性差异。

| Abstract: | Three treatments were designed, CK, furrow irrigation under conventional fertilizer use condition; MC, micro-sprinkling irrigation under conventional fertilizer use condition; MR, micro-sprinkling irrigation under reducing fertilizer use condition. The effects of three different fertigation on summer maize vegetative growth, reproductive growth and yield were studied by the indicators of biomass and grain-filling rate. The experiment results showed that, the treatment of MC can promote summer maize biomass of grain-filling growth period, which was significantly 9.58% higher than CK. There were no significant differences between three treatments of maturity period, and also treatment of MR did not cause reduce the accumulation of biomass. Micro-sprinkling irrigation could significantly promote the rate of grain-filling under conventional fertilizer sue condition, which caused 1.00 d higher of Tmax, 9.99% higher of Wmax and 7.20% higher of P of MC compared to CK. As for MR, it was 1.60 d higher of Tmax, 10.59% higher of Wmax and 14.83% higher of P than CK. The yield of MC was the highest, and this was 6.70% and 5.68% higher than CK and MR(P<0.05). Besides, there was no significant difference between MR and CK. |
