摘要
试验研究在稀土尾矿上不施基肥(对照组),施用粪污处理后的牛场沼液(B)、发酵牛粪(C)、牛粪养殖的蚯蚓粪(E)、发酵牛粪+牛场沼液(C+B)、牛粪养殖的蚯蚓粪+牛场沼液(E+B)5种基肥处理后,对皇竹草农艺性状及产量的影响。结果表明:B处理未能提升皇竹草存活率、农艺性状和产量,显著低于其余4个处理组,C、E处理与C+B、E+B处理之间的存活率、农艺性状和产量差异不显著。C、E、C+B、E+B处理均能有效提升皇竹草的株高、分蘖数、茎粗、单株高重和产量,株高、单株重和产量上,以E和E+B处理效果最好,分蘖数、茎粗在4个处理组间差异不明显。综上所述,在赣南稀土尾矿上种植皇竹草,施用蚯蚓粪作为基肥对皇竹草农艺性状及产量的提升效果最好。
The study is conducted on rare earth tailings,without applying basal fertilizer(control group),applying manure treatment with biogas slurry from cattle farm(B),fermented cow manure(C),earthworm manure from cow manure farming(E),fermented cow dung+biogas slurry from cattle farm(C+B),and earthworm manure from cow dung farming+biogas slurry from cattle farm(E+B),the impact of these five basic fertilizer treatments on the agronomic traits and yield of Pennisetum hydridum.The results of the study showed that treatment B failed to improve the survival rate、agronomic traits and yield of Pennisetum hydridum,which was significantly lower than the other four treatment groups.There was no significant difference in survival rate、agronomic traits and yield between C and E treatments and C+B and E+B treatments.C,E,C+B,E+B treatments can effectively increase the plant height,tiller number,stem diameter,height per plant and yield of Pennisetum hydridum.The plant height,weight per plant and yield are represented by E and E+B Treatment had the best effect,and the number of tillers and stem thickness were not significantly different among the four treatment groups.In summary,planting Pennisetum hydridum on rare earth tailings in southern Jiangxi,and applying earthworm manure as a base fertilizer has the best effect on improving the agronomic traits and yield of Pennisetum hydridum.
