Abstract:
In order to solve the problems of restrained plant growth and low fruit quality for tomato production in solar greenhouse, plot experiments were performed to study the effects of spraying two different forms of silicon on plant growth and quality of tomato in solar green house. The results showed that both inorganic silicon (ISi) and organic silicon (OSi) applied by spraying on leaves could promote tomato growth, ISi treatment was better than OSi treatment. Compared to control treatment (CK), the chlorophyl content, stem diameter and single fruit weight of ISi-supplied plants were increased by 6.03%-9.53%, 8.74%-12.97% and 35.06% respectively, OSi-supplied plants were increased by 5.60%-6.17%, 5.35%-8.81% and 26.37% respectively. The quality of tomato was significantly improved after using two different forms of silicon fertilizer, but OSi treatment was better. Compared to CK, the Vc and soluble sugar content in tomato fruit of ISi-supplied plants were increased by 21.03% and 15.82% respectively. At the same time, the titratable acidity and nitrate content were decreased by 11.40% and 11.05% respectively. However, the Vc and soluble sugar content in tomato fruit of OSi-supplied plants were increased by 44.29% and 23.91% respectively. At the same time, the titratable acidity and nitrate content were decreased by 13.66% and 25.80% respectively.
