摘 要:针对当前设施蔬菜生产过程中过度施用化肥导致的土壤酸化、土壤质量下降等问题,本试验以设施黄瓜为材料,研究不同用量硅钙镁钾肥对其植株长势、产量、果实品质的影响。结果表明:1在黄瓜初花期调查,T75处理各生长性状指标较好;2黄瓜产量随着硅钙镁钾肥用量的增加呈现先增后减趋势,各处理间以T75的产量、经济收益最高,较对照分别增加16.10%、16.40%,达到极显著水平(P<0.01);3施用硅钙镁钾肥各处理黄瓜果实的维生素C含量均有提高,可滴定酸含量下降,但未达到显著水平。综合比较,T75处理(666.7m^2施75 kg硅钙镁钾肥)对设施黄瓜的田间应用效果(壮苗、增产、提质)最佳。Some problems such as soil acidification and degradation caused by excessive application of chemical fertilizer were present in greenhouse vegetable production. With cucumber as material, the tests were conducted to study the effect of different rates of Si - Ca - Mg - K fertilizer on plant growth, fruit yield and quality. The results showed that the better growth indexes could be obtained under the treatment of 75 kg Si - Ca - Mg - K fertilizer per 666.7m2 ( T75 ) when investigated in the early flowering period. The cucumber yield increased firstly and then decreased with the increase of Si - Ca - Mg - K fertilizer rates. Under T75 treat- ment, the fruit yield and economic benefit reached the highest, which increased significantly (p 〈 0.01 ) by 16.10% and 16.40% respectively compared to the control. The application of Si - Ca - Mg - K fertilizer could increase the vitamin C content and decrease the titratable acid content, but the differences were not sig- nificant. By comprehensive comparison, T75 treatment was the best for greenhouse cucumber to obtain strong seedlings, increase yield and improve aualitv
