滴灌条件下不同肥料对西瓜品质及产量的影响

在日光温室栽培条件下,以京阑西瓜为试材,利用3种不同滴灌肥和1种冲施肥进行了等值田间对比试验。结果表明,3种滴灌肥处理西瓜平均生长速率、叶面积、可溶性固形物含量和平均产量均高于传统冲施肥处理,且差异显著,但3种滴灌肥之间差异不显著;4种肥料处理667m2西瓜产量分别为3580.2、3846.0、3560.2、2953.5kg。综合考虑西瓜产量和品质,3种专用滴灌肥均比传统冲施肥表现出良好的施肥效果,建议在生产中使用滴灌冲施肥。

Effects of Different Fertilizers on Yield and Quality of Watermelons under Drip Irrigation

This experiment was conducted in greenhouse using seeded watermelon Jinglan as testing material.Three treatments of fertilizer application through drip irrigation were tested using local fertilizer application method as check.The testing fertilizer application methods were better than check based on average growth rate,leaf area,soluble solid content and average yield.No significant difference among the three treatments was discovered.The yields for the three treatments and check were 3 580.2,3 846.0,3 560.2 and 2 953.5 kg per 667 m2,respectively.Considering the yield and quality of the watermelons,fertigation methods tested in this experiment are recommended for commercial application.
