糖应用在蔬菜生产上,既可用作蔬菜的叶面肥,又可防治一些病害。在黄瓜幼苗期喷施0.2%的糖液,可使秧苗粗壮、增强植株对霜霉病的抵抗能力。在结瓜期喷施1次,瓜条口感特别好。用1%的糖液喷洒黄瓜,还能防治病毒病。在番茄坐果期喷施0.75%的糖液和0.2%-0.3%的尿素混合液作叶面肥,可使花蕾增大、花穗粗壮。番茄受冻害时及时喷施0.2%=0.5%的糖液能明显降低疫病的发病率。在西瓜膨大期,用300倍稀释糖液喷施叶片2-3次或浇根2-3次,可增
Sugar used in vegetable production, both as a vegetable foliage, but also control some diseases. Spraying 0.2% sugar solution in the cucumber seedling can make the seedling stout and enhance the plant’s resistance to downy mildew. Spraying 1 time in the melon period, melons taste particularly good. Cucumber sprayed with 1% sugar solution, but also control the virus disease. In the tomato fruit setting spraying 0.75% sugar and 0.2% -0.3% urea mixture for foliar fertilizer, can make flower buds grow thick stalks. Tomato by freezing injury timely spraying 0.2% = 0.5% of sugar can significantly reduce the incidence of disease. Swelling in the watermelon, with 300 times diluted sugar spray leaves 2-3 times or pouring roots 2-3 times, can be increased
