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3.8L穴盘基质中添加20g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10g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。 Cucumber as a test material, the use of matrix plug seedling method to study the dosage of mycorrhizal preparations of cucumber seedling mycorrhizal infection rate and growth. The results showed that compared with the control, 20g mycorrhizal agent per 3.8L plug matrix had a higher infection rate of 27% and the seedling growth index was better than that of the control, which was better than that of 10g mycorrhizal agent Significant; we can see that the same mycorrhizal fungi on the rate of crop infection will affect mycorrhizal effect on plant growth, infection rate is more obvious role in promoting growth.
