摘要:

明确滴灌水肥一体化条件下施磷量对新疆密植高产玉米生长、产量形成和磷肥利用率的影响机制,以期为新疆玉米高产稳产和化肥减量增效绿色可持续提供理论依据。试验于2023—2024年在新疆奇台农场玉米高产示范基地开展,在滴灌水肥一体化条件下设置不施磷肥(P0)、纯磷60 kg/hm2(P60)、 90 kg/hm2(P90)、120 kg/hm2(P120)、150 kg/hm2(P150)和180 kg/hm2(P180,CK)6个施磷水平,分析了密植滴灌水肥一体化玉米的叶面积指数(LAI)、光合势(LAD)、干物质积累、收获指数(HI)、穗部性状、产量及产量构成的变化,明确了施磷量对新疆密植滴灌玉米产量和磷肥利用率的影响。结果表明,在滴灌水肥一体化分次施磷条件下,2 a玉米产量随施磷量的增加均呈先增加后趋于平稳的趋势,在P120处理时产量达到最大(18.79~20.94 t/hm2)。施磷量可显著影响玉米的千粒质量和穗粒数。施磷量主要影响了玉米果穗秃尖的长度,与P150、P180处理比较果穗秃尖长差异不显著。玉米关键生育期的LAI随磷肥用量的增加表现出先上升后平稳的变化趋势,其中吐丝期P120处理下玉米的LAI最大为7.56~7.81,与P150、P180处理比较LAI差异不显著,与P120处理相比,P0处理显著降低了21.54%。此外,P120处理的玉米花前、花后干物质累积量与P150、P180处理比较差异不显著,较P0分别提高了37.91%,93.88%。综上所述,滴灌水肥一体化分次施磷显著影响了密植滴灌玉米的LAI、LAD、花前与花后干物质积累以及HI,缩短秃尖长度,提高了穗粒数和千粒质量进而提高玉米产量和磷肥利用效率,实现了玉米产量和磷肥利用效率的协同提高。

Abstract:

The mechanism of the effect of phosphorus application rate on the growth,yield formation and phosphorus fertilizer utilization rate of high-yield maize in Xinjiang under the condition of drip irrigation and fertilizer integration was clarified,in order to provide a theoretical basis for the high and stable yield of maize in Xinjiang and the green sustainability of fertilizer reduction and efficiency increase.The experiment was carried out in the maize high-yield demonstration base of Qitai Farm in Xinjiang from 2023 to 2024.Under the condition of drip irrigation and fertilizer integration,six phosphorus application levels were set up:no phosphorus fertilizer(P0),pure phosphorus 60 kg/ha (P60),90 kg/ha(P90),120 kg/ha (P120),150 kg/ha (P150)and 180 kg/ha(P180,CK).The changes of leaf area index(LAI),photosynthetic potential(LAD),dry matter accumulation,harvest index(HI),ear traits,yield and yield components of maize with water and fertilizer integration of dense planting drip irrigation were analyzed,and the effect of phosphorus application rate on yield and phosphorus fertilizer utilization rate of maize with dense planting drip irrigation in Xinjiang was clarified.The results showed that under the condition of drip fertigation and phosphorus application,the maize yield increased first and then tended to be stable with the increase of phosphorus application in the two years,and the yield was the highest(18.79—20.94 t/ha)at P120 treatment.The amount of phosphorus application significantly affected the 1000-grain weight and grain number per ear of maize.The amount of phosphorus application mainly affected the length of maize ear bald tip.Compared with P150 and P180 treatments,the difference of ear bald tip length was not significant.During the critical growth period of corn,LAI showed a trend of first increasing and then stabilizing with increasing phosphorus fertilizer application rates.The LAI of maize under P120 treatment at silking stage was 7.56—7.81,which was not significantly different from P150 and P180 treatments,but was significantly reduced by 21.54% under P0 compared with P120.In addition,the dry matter accumulation before and after anthesis of maize treated with P120 was not significantly different from that of P150 and P180 treatments,which was 37.91% and 93.88% higher than that of P0,respectively.In summary,drip fertigation and phosphorus application significantly affected LAI,LAD,pre-anthesis and post-anthesis dry matter accumulation and HI,shortened bald tip length,increased grain number per spike and 1000-grain weight,and then increased maize yield and phosphorus utilization efficiency,and realized the synergistic improvement of maize yield and phosphorus fertilizer utilization efficiency.
