- 摘要:
- 以黄瓜为试材，采用基质穴盘育苗的方法，研究了不同用量菌根制剂对黄瓜幼苗菌根侵染率及生长的影响。结果表明：与对照相比每3.8 L穴盘基质中添加20 g菌根制剂处理的幼苗侵染率较高为27%，且幼苗生长指标总体较好，比添加10 g菌根制剂处理的促进生长作用显著；可知，同一菌根真菌对作物侵染率的差异会影响菌根对植物的促生作用，侵染率高时促生作用更明显。
- Abstract:
- Taking cucumber as material,the uses of substrate for cucumber plug seedling and the effect of different dosage of mycorrhizal agent on cucumber seedling growth and mycorrhizal infection rate were studied.The results showed that compared with the control,adding 20 g treated seedlings had higher infection rate which was 27%,and the indexes of seedling growth overall was good and had a significant difference with the addition of 10 g inoculant treatment on the growth of cucumber.These results suggested that for the same mycorrhizal fungi,plant growth promoting effect depended on the different plant infection rate,if infection rate was high,the growth promoting effect would be more obvious.
