The Study of Different Fertilization on Fruit Vegetables in the Greenhouse
Jiang, W. J. and R. C. Huang
The highest yield of greenhouse cucumber was found with controlled-release fertilizer (CRFs) (120 kg), followed by traditional fertilization (102 kg), Fluid fertilizer (64 kg), foliar fertilizer (52 kg), and blank of 19 kg. Poor yield of the treatment foliar fertilization was mainly due to the slow growing caused by no use of basal fertilizer. The slow growth in the early stage resulted in the small leaf area and poor nutrient uptake. The yield of traditional fertilization, CRFs, Fluid fertilizer and foliar fertilization treatments were not significant difference but were higher than that of blank treatment.
The brix values of CRFs and Fluid fertilizer were higher than those of traditional fertilization and blank treatments. Growth performance varied in cucumber and melon with different fertilization treatments. Thus, different crop should use different fertilization. Melon yield was higher than cucumber, maybe due to the melon fruits was bigger and harvested one time but cucumber fruits were harvested many time. If based fertilizer were used in the early growing stage followed by drip irrigation or foliar fertilizer application, cucumber may have batter growth performance.
