ABSTRACT In order to study the effect of municipal solid waste (MSW) compost and vermicompost on morpho-physiological properties and yield of canola under drought stress conditions, an experiment was conducted as factorial arrangement based on randomized complete block design with four replications. Treatments consisted of three levels of water regimes, including: 75% of the field capacity for well-watered and 55% and 35% for moderate and severe stress, respectively, and biofertilizer in five levels, including: nonapplication of biofertilizer (control), application of MSW compost, and vermicompost at 2% and 4% levels. Results showed that interaction of irrigation and biofertilizer had significantly affected on all traits except leaf area ratio and nitrogen percent. The moderate and severe stress significantly reduced all traits compared to normal irrigation. Application of 4% vermicompost was resulted in increased growth, biomass and yield of canola under normal irrigation, moderate and severe drought stress compared to other biofertilizer treatments.

干旱胁迫条件下蚯蚓粪和城市固体废物堆肥对油菜生长和产量的影响

摘要 为了研究城市固体废物 (MSW) 堆肥和蚯蚓堆肥在干旱胁迫条件下对双低油菜籽形态生理特性和产量的影响，进行了一项基于随机完全区组设计的因子安排试验，重复四次。处理包括三个水平的水分状况，包括： 75% 的田间容量的充足浇水和 55% 和 35% 的中度和重度压力，以及五个水平的生物肥料，包括：不施用生物肥料（对照）， MSW 堆肥和蚯蚓堆肥的施用量分别为 2% 和 4%。结果表明，灌溉和生物肥料的相互作用对除叶面积比和氮百分比外的所有性状都有显着影响。与正常灌溉相比，中度和重度压力显着降低了所有性状。与其他生物肥料处理相比，在正常灌溉、中度和重度干旱胁迫下，施用 4% 蚯蚓粪可提高油菜的生长、生物量和产量。
