許多长期試驗的結果表明,在椰园定期进行中耕,不仅会使肥料发揮更大的效用,而且,即使不施肥,也有显著的增产效果。印度喀撒拉戈德的中央椰子試驗站在一个試驗中也获得了上述的結果。該試驗区位于深厚的紅砂壤土,完全依靠天然降雨,每年的中耕措施只是犂两、三遍,并视需要除草一、二次。 The results of many long-term trials indicate that regular cultivation in coconut groves will not only make fertilizers more effective, but also have a significant yield increase without fertilization. The Central Coconut pilot station in Kasaladad, India, also obtained the above results in one experiment. The test area is located in the deep red sandy loam soil, completely rely on natural rainfall, cultivation measures every year only plow two or three times, and if necessary weeding the first and second.
