摘要
以豆角为试验材料，进行大田试验，研究喷施有机营养型专用叶面肥的效果。结果显示：豆角喷施有机营养型专用叶面肥与对照（清水）比较有极显著的增产效果，增产率广州五山点达6．8％～15．5％，博罗点达10．9％～21．2％，适宜的喷施浓度为450-600倍。喷施有机营养型专用叶面肥还具有提高豆角收获物Vc含量和可溶糖含量，提高收获部位的氮、磷、钾干物养分含量的效果。
The field experiments on the effects of Organic Nutrient Special Solution （ONSS） applied on cowpea Vigna unquiculata W. ssp. sesquipedalis indicated that the application of ONSS had extreme yield - increased effect compared with the contrast （clear water spraying）, with the scopes of 6.8 % - 15.5 % in Guangzhou and 10.9 % - 21.2 % in Boluo county. The adequate concentration for spraying were 450-600 times of solutions after dilution which the most significant effects were obtained, The spraying of ONSS could improve the content of Vitamin C and soluble sugar of the harvest parts, and increase the NPK content in dry basis and the absorption amounts of nutrient.
