摘要
本文研究了水肥一体化对绿萝生长指标、水分利用率和肥料利用率的影响。结果表明:与常规施肥相比,水肥一体化施肥处理的盆栽绿萝总根长、根系表面积、茎长、叶面积、SPAD值分别提高36.41%、47.13%、39.79%、26.65%、8.82%,N、P2O5、K2O的利用率分别提高32.86%、31.43%、34.65%,水分利用率提高38.43%;水肥一体化减量施肥处理的盆栽绿萝总根长、根系表面积、茎长、叶面积、SPAD值分别提高14.19%、11.53%、8.13%、9.05%、1.39%,N、P2O5、K2O的利用率分别提高6.19%、8.72%、4.82%,水分利用率提高8.33%。与常规施肥相比,水肥一体化技术的利用明显提高了绿萝的品质、水分利用率和肥料利用率。
In this paper,the effects of water and fertilizer integration on the growth index,water utilization rate and fertilizer utilization rate of Scindapsus aureus were studied.The results showed that compared with conventional fertilization,the total root length,root surface area,stem length,leaf area and SPAD values of potted S.aureus under water and fertilizer integration with normal fertilization treatment respectively increased by 36.41%,47.13%,39.79%,26.65%,8.82%,the utilization rates of N,P2 O5 and K2 O respectively increased by 32.86%,31.43%,34.65%,the water utilization efficiency increased by 38.43%;the total root length,root surface area,stem length,leaf area and SPAD values of potted S.aureus under water and fertilizer integration with reduced fertilization respectively increased by 14.19%,11.53%,8.13%,9.05%,1.39%,the utilization rates of N,P2 O5 and K2 O respectively increased by 6.19%,8.72%,4.82%,the water utilization efficiency increased by 8.33%.Compared with conventional fertilization,the utilization of water and fertilizer integration technology significantly improves the quality,water utilization efficiency and fertilizer utilization efficiency of S.aureus.
