有机废弃物对韭兰叶片可溶性蛋白及土壤根际脲酶活性的影响

摘要

In order to promote the standardization production of Zephyranthes grandiflora,ecological soilless cultivation substrates were screened out by comparing the effect of 5 recipes of organic wastes on the soluble protein of Zephyranthes grandiflora and the urease activities of soil.The cultivation matrix were the combinations of dregs of a decoction,mushroom compost,straw,cow dung and wormcast.The results showed that the content of soluble protein in Zephyranthes grandiflora leaf and soil urease activity were first reduced after rised,which was consistent with the growth of plants.The trend of soluble protein content of Zephyranthes grandiflora and the soil urease activity in the five recipes of organic wastes were exhibited adding cow dung or wormcast organic ecological soil>single adding cow dung or wormcast garden soil>normal garden soil.%为了促进韭兰标准化生产,通过分析比较5种处理组合基质对植物营养成分及土壤酶活性的影响,以韭兰为种植试材,药渣、菇渣、秸秆、牛粪、蚯蚓粪等有机固体废弃物为栽培基质材料,进行植物有机生态型无土栽培试验.结果表明:韭兰植物叶片中的可溶性蛋白含量和土壤中脲酶活性均表现为先降低后升高的趋势,与植物生长状况相一致.5种处理组合中韭兰叶片的可溶性蛋白含量和根际土壤中脲酶的活性表现趋势为:添加牛粪或蚯蚓粪的有机生态土>单一添加牛粪或蚯蚓粪的园土>普通园土.
