本试验对混种于椰林下的巴拉草和蝴蝶豆进行不同的施肥处理。混种牧草对施用大量氮、钾和少量磷(400—75—150和400—75—300)有显著反应,如巴拉草生长迅速茁壮,导致它比豆科植物占优势。不施或少施氮肥,蝴蝶豆则抑制禾本科巴拉草的生长,用400—75—300和400—150—300氮、磷、钾处理的干物质年产量最高,平均为9.75吨/公顷/年,施用100—75—0和较高施肥量的,其生长和干物质产量差异不显蓍。三年间不施肥的对照区的干物质产量最低。
In this experiment, different fertilizers were applied to Bala grass and butterfly beans mixed with coconut groves. Mixed grazing significantly reacts with large amounts of nitrogen, potassium, and small amounts of phosphorus (400-75-150 and 400-75-300), such as the rapid and robust growth of the parasite, which leads to its predominance over legumes. With or without nitrogen fertilizer, butterfly beans inhibited the growth of Poaceae, with the highest annual dry matter yield of 400-75-300 and 400-150-300 nitrogen, phosphorus and potassium, with an average of 9.75 tons / ha / Year, the application of 100-75-0 and a higher amount of fertilizer, the growth and dry matter yield difference was not significant. In the three-year control area without fertilization, the dry matter yield was the lowest.
