餐余蚓粪的基质配方及对小白菜育苗的影响

将餐余废弃物进行滤干、脱油、脱盐处理,与菌渣按一定比例复配进行蚯蚓堆肥,形成餐余蚓粪。将餐余蚓粪与泥炭、珍珠岩、蛭石按不同比例进行复配,进行小白菜育苗基质试验研究,通过分析小白菜生长情况,筛选出适合小白菜育苗的最佳基质配方。结果表明,经过不同流程的处理后,餐余废弃物的EC值逐渐降低,有机质、养分含量均很高,可以作为蚯蚓饲料;与常规基质相比,添加不同比例的餐余蚓粪均不同程度地促进小白菜出苗率、株高、茎粗、地上部生物量、根系活力等。所有处理中,以40%餐余蚓粪+20%泥炭+15%珍珠岩+25%蛭石的综合效果最好,是适宜小白菜生长的最佳基质配方。

Substrate formula of food waste vermicomposting and its effects on Chinese cabbage seeding

In this paper,the food waste was filtered,de-oiled and desalinated,and vermicomposted in a certain proportion with mushroom residue to produce the vermicompost.Then the food waste vermicompost,peat,perlite,and vermiculite were mixed with different proportions to select the best substrate for Chinese cabbage seedings through the analysis of Chinese cabbage growth.The results showed that,the EC value of the food waste gradually decreased after treatment,and the organic matter and nutrient content were high,which could be used as food of earthworms.Compared with the conventional substrate,the addition of different proportions of food waste vermicompost promoted the emergence rate,plant height,stem diameter,above-ground biomass and root activity of Chinese cabbage in different degrees.In all treatments,the comprehensive effect of 40%food waste vermicompost,20%peat,15%perlite and 25%vermiculite is the best,which is the best substrate formula for the growth of Chinese cabbage.
