西马来西亚胶园用的肥料,差不多一半是氮肥。常用的氮肥是硫酸铵、硝酸铵和尿素。它们促进胶树生长的效能,取决于对胶树提供的铵态氮和硝态氮数量,以及它们对土壤中的阳离子和阴离子水平的总的影响。幼龄胶树的施肥量较大,特别是在头一年。按照马来西亚橡胶研究院推荐的施肥方案,一龄幼树每公顷年施氮肥量较高,施在植株的30.5厘米半径的根圈内。由于幼树的根系 West Malaysia plastic garden fertilizer, almost half of nitrogen fertilizer. Common nitrogen fertilizers are ammonium sulfate, ammonium nitrate and urea. Their effectiveness in promoting gum tree growth depends on the amount of ammonium and nitrate nitrogen available to the gum tree and their combined effect on the level of cations and anions in the soil. Young gum tree fertilizer larger, especially in the first year. In accordance with the fertilization program recommended by the Malaysian Rubber Research Institute, young shoots of young trees are high in nitrogen fertilizer per hectare and are applied to the 30.5 cm root circle of the plant. Because of the sapling root system
