不同农业废弃物营养块对西瓜育苗效果的影响

【目的】探索农村废弃物高值资源化利用新途径,为农村废弃物综合利用提供参考。【方法】对几种农村废弃物进行基质化处理,按不同比例配制压成5种育苗营养块,以泥炭育苗营养块为对照,以西瓜种子为试验材料,调查9个常用的农艺性状指标,并通过平均隶属函数值法分析对各处理幼苗的综合素质,对不同配方营养块的育苗效果进行研究。【结果】各设置处理中,以芦苇残渣与牛粪比例为7∶3处理的幼苗生物量及总生物量最高,幼苗综合素质表现最好,其平均隶属函数值为0.724。【结论】芦苇残查与牛粪比例为7∶3的营养块可替代泥炭育苗营养块,应用于西瓜等作物的规模化、产业化育苗。

Effect of different agricultural waste nutrition sources on growth of watermelon seedlings

【Objective】The present study was conducted to explore the new method of watermelon cultivation using high-value agricultural wastes as nutrient source in order to recycle the agricultural resources. 【Method】Several agricultural wastes were mixed in different ratios and used for seedling nutrition, peat nutrition was used as control. The agronomic traits of watermelon cultivated with these nutrition sources were investigated. The subordinate function values were used to find out the effects of different agricultural waste nutrition source on seedling growth of watermelon. 【Result】The treatment of 7∶3 ratio of reed residue∶cattle manure showed highest seedling biomass and total biomass followed by CK. The comprehensive quality of seedlings were the best in this treatment and its average subordinate function values was 0.724. 【Conclusion】 Reed residue∶cattle manure in ratio of 7∶3 was found good as a source of nutrient for culturing watermelon seedlings, and it may be recommended for large-scale production of watermelon seedling.
