土壤中添加菌草平菇菌糠基质对莱牧1号幼苗生长的影响
Effects of Adding the Spent Mushroom Substrate of Juncao Pleurotus ostreatus in Soil on the Growth of Pennisetum sp.Seedlings
摘要
Abstract
In order to improve the recycling utilization efficiency of edible fungus substrates in the cultivation of Juncao,the seedlings of Pennisetum sp.were used as the experimental material,and seven treatments with different amounts of Pleurotus ostreatus spent mushroom substrate were set up,including CK(0 g·kg-1),SMS1(10.0 g·kg-1),SMS2(25.0 g·kg-1),SMS3(50.0 g·kg-1),SMS4(75.0 g·kg-1),SMS5(100.0 g·kg-1),and SMS6(150.0 g·kg-1),respec-tively,thus to study their effects on the growth of Pennisetum sp.seedlings.The results showed that when Pennisetum sp.grew for 20 days,the SMS4 treatment group performed the best,with the plant height of 26.9 cm,which was significantly different from that in the other treatments.After 50 days of growth,the stem diameter of Pennisetum sp.in the SMS4 treatment group increased by 35.25%compared to the CK control group,reaching 16.50 mm,and the root length was 92.96 cm,which was better than that in other treatment groups.In addition,when Pennisetum sp.grew for 45 days,the chlorophyll content and net photosynthetic rate in the SMS4 treatment group were the highest.Therefore,adding the Pleurotus ostreatus spent mushroom substrate to the soil was beneficial for the growth of Pennisetum sp.seedlings,and the effect was the most significant when the addition amount reached 75.0 g·kg-1.关键词
