营养要求与施肥反应施肥能改善椰树营养生长,促使早结果和导致高产。氮和磷肥能使植株速生,因而是幼龄椰子树生长早期的主要养分,而钾肥在结果阶段较重要。曾有人根据椰树每公顷年产果7,000个计算,估计每公顷椰树每年从土壤中吸收的主要养分为:92公斤氮,41公斤磷(五氧化二磷),137公斤钾(氧化钾),38公斤镁(氧化镁)和23公斤钙(氧化钙)。根据这些数 Nutritional Requirements and Fertilization Response Fertilizers improve the vegetative growth of coco, prompting early results and leading to high yields. Nitrogen and phosphate fertilizers can make plants faster, and therefore are the main nutrients in the early growth of young coconut trees, while potassium is more important in the outcome stage. According to the calculation of the annual yield of 7,000 coco per hectare, it has been estimated that the main nutrients absorbed by the coco per hectare from the soil are 92 kg of nitrogen, 41 kg of phosphorus (phosphorus pentoxide), 137 kg of potassium (potassium oxide) , 38 kilograms of magnesium (magnesium oxide) and 23 kilograms of calcium (calcium oxide). Based on these numbers
