4种叶面肥在设施白黄瓜上的喷施效果

为选择合适的叶面肥，研究了叶满绿800倍液(F1)、绿叶先锋667倍液(F2)、三效绿叶神600倍液(F3)、植物益生源2000倍液(F4)4种叶面肥苗期喷施对白黄瓜植物学性状、抗病性及产量的影响。试验结果表明，喷施叶面肥后，除雌花开放最高节位外，4种叶面肥处理的其他植物学性状优于对照(喷清水)，雌花节率、瓜长、瓜粗、单瓜质量、产量均高于对照，其中F3和F4处理的黄瓜植株综合表现最好、单瓜质量最大、667 m2产量最高、发病率最低。

Effects of Four Kinds of Foliar Fertilizers on White Cucumber in Greenhouse

In order to screen out appropriate foliar fertilizer for white cucumber, we studied the effects of spraying four foliar fertilizers, Yemanlv 800 times liquid (F1), Lvyexianfeng 667 times liquid (F2), Greenleaf Deity 600 times liquid (F3) and Plant Prebiotics 2 000 times liquid (F4), at seedling period respectively on the botanical characters, disease resistance and yield of white cucumber in greenhouse. The results showed that, except for the highest blooming node of female flower, the four foliar fertilizer treatments had better other botanical characters, and higher female flower rate, fruit length, fruit diameter, single fruit weight and yield than those of CK (spraying the same amount of water). Among the four treatments, F3 and F4 treatments had the best comprehensive characters, heaviest single fruit weight, highest yield and lowest disease incidence.
