摘要
试验研究了蚯蚓粪肥不同施入水平对牧草品质及其产量的影响,进行了5次刈割测产,测定了桂牧1号象草单株株高、单株鲜重、鲜草产量,分析了牧草中粗蛋白、粗纤维、粗灰分及重金属铜、锌、砷含量。研究结果表明,利用蚯蚓粪肥栽培桂牧1号象草,并用猪场沼液灌溉,能明显促进其生长,提高牧草产量,改善牧草品质,增加适口性。当蚯蚓粪肥单株施入量为2.00 kg,即2.55 kg/m2时,试验效果最佳。随着试验进行,蚯蚓粪作为有机肥到后期吸收更加充分,对牧草后期生长有明显的影响,牧草单株株高、单株鲜重、刈割产量均有明显增加,能有效增加牧草产量,提高经济效益。
Effect of different fertilizer rate of earthworm manure on the yield and quality of Pennisetum purpureum cv. Guimu No. 1 were studied. The cutting produciton were determined 5 times,the plant height,fresh weight and fresh yield were determined,and the contents of crude protein,crude fiber,crude ash and heavy metal copper,zinc and arsenic in Guimu No. 1 were analyzed. The results show that,Using wormcast cultivated and pig farm biogas slurry irrigation can significantly promote the growth,increase forage yield,improve forage quality,increase palatability of Guimu No. 1. When the fertilizer rate of earthworm manure per plant was 2 kg,which is 2. 55 kg / m2,had the best test results. With the test,earthworm manure as organic fertilizer to the late absorb more fully,in the late period of Guimu No. 1 growth had obvious influence,plant height,fresh weight per plant,cutting yield increased significantly,effectively increased the yield,improved economic efficiency.
