叶面肥施用和土壤处理对蔬菜产量和病虫害防治的影响

Effects of Foliage fertilizer Utilization and Soil Treatment on Crop Yield,Plant Diseases and Insect Pests in Beassica pekinensis and Brassica juncea

在大白菜和芥菜栽培过程中施用两种叶面肥和化肥,并以不施肥做对照。同时对试验土壤分别用土壤虫菌通杀剂和竹醋液处理。探讨不同肥料处理和土壤处理对大白菜和芥菜产量和病虫害防治的影响。结果表明,不同肥料处理引起大白菜和芥菜的产量差异不显著,但与不施肥区差异显著;而使用叶面肥大白菜和芥菜的病害和虫害株数都明显少于使用化肥和不施肥区,且差异显著(芥菜的病害受天气影响除外)。不同土壤处理引起的大白菜和芥菜产量及病虫害差异不显著。可见,叶面肥的施用能保证大白菜和芥菜的产量,减少病虫害,从而减少农药的使用而提高作物品质。

During the growth of Beassica pekinensis and Brassica juncea two kinds of foliage fertilizers and inorganic compound were applied, and compared with no fertilizer. At the same time the soil was treated with different disinfectors. The results showed that different fertilizers made no significant crop yield difference each othere, but significant to no fertilizer; and individuals affected by plant diseases and insect pests which are fertilized with foliage fertilizer were much fewer than that with inorganic compound and no fertilizer. No signifeant differnce exsited in yield and diseases and insect pests with differen soil treatments.
