施用专用叶面营养液对瓜类蔬菜产量和品质的影响

Effect of special foliar nutrient solution on yield and qualities of melon vegetable

以节瓜和丝瓜为试验材料，进行大田试验，研究喷施专用叶面营养液对瓜类蔬菜产量和品质的效应。结果显示：节瓜和丝瓜喷施专用叶面营养液与对照（清水）比较有极显著的增产效果，增产幅度分别为8．2％～17．8％和6．9％～11．3％，节瓜和丝瓜较适宜的喷施浓度分别为600倍和450倍。使用专用叶面营养液具有改善农产品品质，提高养分吸收利用，降低硝酸盐的效果。

The effects of Special Foliar Nutrient Solution （SFNS） applied on Benincasa hispida Coga. and towel gourd （Luffa acutangula Roxb. ） indicated that the application of SFNS had extreme yield- increased effect compared with the contrast, with the scopes of 8.2% - 17.8% and 6.9% - 11.3%. The more adequate concentration for spraying was 600 times and 450 times by dilution respectively. The spraying of SFNS could improve the quality of farm product, promote the absorption and utilization of NPK and decrease the nitrate content in farm product.
