植物免疫诱抗剂对黄瓜生长和产量的影响

Effects of Plant Immune Inducers on Growth and Yield of Cucumber

为明确植物免疫诱抗剂氨基寡糖素和几丁聚糖对黄瓜作物生长和产量的影响,在黄瓜生育期4次施用2种植物免疫诱抗剂,并在苗期、生育期测定黄瓜株高、茎粗、单果质量和产量等指标。结果表明:黄瓜苗期,株高增高4.4%~7.4%,茎粗增加2.7%~6.9%;生育期内,黄瓜株高增高10.57%~13.57%,茎粗增加8.1%~13.8%,地上部鲜质量增加17.5%,干质量增加18.5%,单瓜质量增加8.01%~10.12%,每667 m~2增产约300 kg;综上说明,植物免疫诱抗剂对黄瓜具有较好的促生和增产效果。

In order to clarify the effects of plant immune inducers(aminooligosaccharide and chitosan)on the growth and yield of cucumber,two plant immune inducers were applied for four times during the growth period of cucumber,and the plant height,stem diameter,weight of single fruit and yield of cucumber were measured at seedling and growth stages.The results showed that the plant height and stem diameter of cucumber during seeding stage increased by 4.4%-7.4%and 2.7%-6.9%,respectively.During the growth period,the plant height of cucumber increased by 10.57%-13.57%,the stem diameter increased by 8.1%-13.8%,the fresh weight of overground increased by 17.5%,the dry weight increased by 18.5%,and the weight of single fruit increased by 8.01%-10.12%.The yield increased by about 300 kg per 667 m2.In conlusion,plant immune inducer had a good effect on promoting growth and increasing yield of cucumber.
