Abstract：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 quality.
