硼肥不同施用方式对黄瓜生长的影响

以津早1号黄瓜为材料，研究硼砂不同施用方式对黄瓜生长的影响。试验结果表明，硼肥采用基肥条施和叶面喷施2种方式，均能有效地提高黄瓜体内叶绿素含量和净光合速率；使霜霉病和白粉病发病率显著降低，产量显著提高；使 VC 含量显著提高，可溶性固形物含量显著降低。生产中建议，硼砂采用叶面喷施（浓度为0.15%），从定植后10 d 开始，每隔10 d 喷施1次，连续喷施2~3次；或者作基肥一次性施入，施用量0.5 kg/667 m2。

Effects of Different Application Patterns of Boron Fertilizer on Cucumber Growth

This study used Jinzao No.1 as material to research the effects of different application patterns of borax on the growth of cucumber. The results showed that, when borax was used as base fertilizer and foliage fertilizer respectively, the chlorophyll content and net photosynthetic rate increased effectively, and yield and vitamin C content increased significantly, while disease incidences of downy mildew and powdery mildew as well as soluble solid content decreased significantly. Therefore, when borax was used as foliage fertilizer, the recommended concentration was 0.15% , and it should spray every 10 days for 2-3 times after the plants were planted for 10 days. When borax was used as base fertilizer, the suitable application was 0.5 kg/667 m2 for once.
