农业废弃物不同配方营养块的理化性质及其对黄瓜育苗的影响

为探索农业废弃物高值资源化利用途径,以纸厂废弃物芦苇渣、畜禽粪便等为主要原料,经发酵腐熟与基质化处理后,压制成育苗营养块,比较分析其理化性质及对黄瓜育苗的影响。结果表明,原料配方对育苗营养块理化性质影响明显,以T1处理(芦苇渣∶牛粪∶泥炭=7∶3∶0)总养分含量最高,且培育的黄瓜苗农艺性状优势明显,叶绿素含量也显著高于其他处理。平均隶属函数值法研究结果显示,T1处理幼苗综合素质最好。

Effects of Nutrition Blocks with Different Formulae of Agricultural Wastes on Seedling Effect of Cucumber

In order to explore the ways of high-value resource utilization of agricultural wastes,reed residue from paper mill wastes,agricultural wastes,livestock and poultry manure were chosen as the main raw material to made seedling nutrition blocks after fermentation maturity and matrix processing,and the physical and chemical properties and the effects on seedling effect of cucumber were compared.The results showed that there were obvious effects of raw materials formula on physical and chemical properties of seedling nutrition blocks;T1 treatment(reed residue∶cattle manure∶peat=7∶3∶0) had the highest total nutrient contents and obvious advantages of agronomic traits of cucumber seedling,and the chlorophyll content in T1 treatment was also higher than that in others significantly.The results of average subordinate function values indicated that the comprehensive quality of seedlings in T1 treatment was the greatest.
