Effect of Different Concentrations of Water Soluble Organic Fertilizer on Yield and Quality of Tropical Facilities Cultivated Melon

【Objective】Tropical facility melon yield and quality have been studied for application to explore the effect of water soluble organic fertilizer on melon in the hope of providing theoretical and practical basis for the promotion of tropical foliage facilities melon. 【Method】By designing 4 kinds of combinations of water soluble organic fertilizer,with water as contrast,the effect of the foliar fertilizer under different concentrations on growth and development,yield and quality of tropical facilities melon was studied. 【Result】The results showed that the area of melon leaf sprayed with the water soluble organic fertilizer was 16. 56%,18. 36%and 16. 56% higher than that of the control on average during the observation period. Leaf SPAD value on average was increased by 13. 75%,14. 98% and 14. 98% respectively than that of the control. Longitudinal andtransverse diameter of melon increased,the longitudinal diameter was increased by 6. 75%,14. 53%,15. 88%and 14. 53% respectively,the transverse diameter increased by 3. 28%,7. 12%,9. 33% and 7. 12%,respectively. With the increase of dosage,the yield was increased by 9. 01%,26. 44%,28. 50% and 9. 01%,respectively. 【Conclusion】Effects of different concentrations of water soluble organic fertilizer on the yield and quality of tropical facilities melon were significant,and using the method can stretch tendril period 200 ml /(667m2·time),other times 250 ml/(667m2·time) can significantly increase yield and improve quality.
