茶渣有机肥及其对植物生长的影响

废弃茶渣的资源化越来越受到重视,试验通过控制外界环境与加入营养物的量,研究影响废弃茶渣发酵的因素,结果表明发酵时间和营养物量起决定作用。为测试发酵后茶渣的肥效,用不同量的茶渣有机肥种植油冬儿菜和玉米,通过测定农作物生物指标发现:施用茶渣有机肥的植株生长情况较好,植株过氧化氢酶的活性、长势和茎的粗细等生物指标都有明显提高,说明了茶渣有机肥能促进植株生长。当土壤中发酵后茶渣添加量达5%时,油冬儿菜的单株直径、株高和生物量分别为对照的169.56%、113.6%和600.7%,后茬作物玉米单株直径、株高和生物量分别上升了57.1%、72.3%和188.0%。

Waste Tea Made Manure and Its Effect on Plant Growth

This research study the key factors of waste tea-leaf fermentation by adding different amount of nutrients.It showed that the days of aerobic and the amount of nutrients played a determined role.Under the best condition,fertilizers nutrients and metal indicators are consistent with the relevant national standards.The determination of crop biological index showed that plants with organic waste tea-leaf grew better.The CAT activity,the side of the stem and the length also increased significantly,showing that ...
