Effects of Different Fertilizers on Nutrient Absorption and Yield and Quality of Tomato

The effects of different fertilizers,conventional fertilization( CK),nitrate nitrogen( NN) and its reduction of 20%( N- N),urea nitrogen fertilizer( UN),granular organic fertilizer( MN),on nutrient absorption and yield and quality of tomato were studied by field test. The results showed that different fertilizations had different effects on tomato nutrient absorption,chlorophyll content,yield and fruit quality. The chlorophyll content of MN treatment was higher than that of the other treatments; the yield and contents of VC,flavonoid and total phenol of MN treatment increased by 9. 24%,5. 57%,3. 65% and 17. 32% respectively compared with CK. It indicated that MN treatment could obviously improve the fruit quality. Under the conditions of this experiment,applying the same nitrogen amount of organic fertilizer could obviously improve the tomato yield and fruit quality.
