摘要
【目的】研究叶面施肥对热带设施甜瓜产量及品质影响,探讨甜瓜有机水溶肥叶面施肥的应用效果,为热带设施甜瓜叶面肥的推广提供理论与实践依据。【方法】设计肥料浓度4种水平组合,以清水为对照,研究有机水溶肥料不同浓度对热带设施栽培甜瓜生长发育、产量和品质的影响。【结果】喷施有机水溶肥料的处理各次观测的叶片面积较对照高16.56%、18.36%和7.38%。叶片SPAD值平均较对照分别提高了13.75%、14.98%和13.70%。甜瓜纵横径增加,纵径分别提高6.75%、14.53%、15.88%和16.65%,横径分别提高3.28%、7.12%、9.33%和9.47%。随着用量的增加,产量也呈增加趋势,增产比例分别为9.01%、26.44%、28.50%、31.02%。【结论】不同浓度水溶肥料叶面喷施对热带设施甜瓜产量和品质有明显影响,采用伸蔓期200 ml/(667 m2·次),其它时期250 ml/(667 m2·次)的喷施方法可显著提高产量,提升品质。
【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.
