Abstract

Abstract: The characteristics of main fertilizer needed by cucumber were analyzed, and a liquid water-soluble fertilizer was studied. The nutrient contents of N, P₂O₅, K₂O, Ca, Mg, Zn and Fe were 100.0, 12.5, 25.0, 75.0, 25.0, 8.0 and 1.0 g/L, respectively. The products complied with the agricultural industry standard of water-soluble fertilizers containing calcium and magnesium（NY2266—2012）. The results showed that the seed soaking effect of 1 400 times fertilizer dilution was better, and the germination rate, germination potential and relative water content of seedlings were increased by 18.00, 22.00 and 0.02 percentage points respectively compared with that of water control. Germination index, vigor index, first order lateral root number, taproot length, hypocotyl length and hypocotyl diameter increased by 13.1%, 29.4%, 38.5%, 31.7%, 35.6% and 39.4%, respectively. The relative electrical conductivity of seedlings decreased by 31.5%. Seaweed liquid had a good promoting effect on seed soaking effect of water-soluble fertilizer.

Key words: water-soluble fertilizer, cucumber, medium elements, dipping, seaweed
