不同肥料对基质栽培樱桃番茄产量与品质的影响

在用滴灌方法统一供给营养液的条件下,定植前在同种基质中混入不同的肥料作为基肥或者在生长期喷施叶面肥进行不同肥效试验。结果表明,叶面肥和有机肥均能提高番茄产量,生物有机肥处理产量最高,较对照增加了13.6%,其次为消毒鸡粪处理,较对照提高8.9%。有机肥与化肥配施有明显改善番茄品质的作用,可溶性固形物较对照提高2.08%～6.5%,VC提高4.1%～11.3%,而硝酸盐含量下降8.5%～14.7%。叶面肥较有机肥更能促进株高、茎粗等植物学性状的生长。

Effect of Different Fertilization on Yield and Quality of Cherry Tomato in Substrate Culture

Under the condition of supplying the same nutrition solution concentrations by drip irrigation, the effect of substrate Culture on the yield and the quality of cherry tomato was studied by adding different fertilizer before planting or spraying foliar fertilizer in the growth period. The experiment results showed that the yield and the quality could be both increased by applying foliar and organic fertilizer. The best bio-organic fertilizer treatment increased the yield of cherry tomato by 13.6%, the better disinfect chicken treatment increased the yield by 8.9%. The quality can be improved by applying organic fertilizer and the chemical fertilizer at the same time, solu- ble solids and Vc was increased by 2.08%- 6.5% and 4.1%- 11.3%, respectively. But nitrate content was decreased by 8.5%- 14.7% . The foliar fertilizer promoted better the growth of plant height and stem diameter than the other two.
