Abstract:

In order to explore the artificial cultivation technology of Allium mongolicum, the sowing experiment was carried out according to the multi-factor split zone. The different proportions of sand and clay were put into pottery pot as cultivation substrate, and the seeds were divided into treatment and non-treatment, the emergence rate and height of the seedlings were observed. At the same time, the cultivation substrate with the ratio of sand and clay 1:1 was selected as the research object, and 1-year old A. mongolicum seedlings were transplanted into pottery pot. After 1 year of cultivation, different treatments like loosening the soil and irrigation were conducted to observe the fresh biomass and height of A. mongolicum. The results showed that treatment of seed had a great effect on the germination rate, which was significantly higher than that of the untreated seeds (P<0.01). Substrate had a great influence on emergence rate of the seedlings, the seed emergence rate of pure sand was significantly higher than that of half soil and half sand, and pure clay (P<0.05). The fresh biomass of potted A. mongolicum was not significantly affected by loosening soil or not (P>0.01); irrigation treatment had a great effect on the height growth of A. mongolicum, the height growth of 600 mL/time treatment was large, but it was not significantly different with 800 mL/time (P>0.05), and it was significantly different with other treatments (P<0.05).
