本文系橡胶树施用螯合稀土钼(简称CRM)微肥的基本总结。试验表明,螯合稀土钼微肥兼有橡胶树生长所需的营养和刺激元素。它具有营养成分利用率高,作物易于吸收的特点,在促进橡胶树生长、刺激排胶和控制死皮病的发展方面均有明显效果。将螯合稀土钼微肥原液用清水稀释至0.2～2.0%的浓度,在割胶期内涂于割胶口和割胶面上,每月1～2次,年涂5～10次,净增产率达8.6～37.6%。与乙烯利混合施用效果更佳。螯合稀土钼微肥在橡胶树上施用方便,用量少,经济效益明显,具有广阔的发展前景。
In this paper, the rubber tree chelated rare earth molybdenum (referred to as CRM) micronutrient basic summary. Experiments show that chelated rare earth molybdenum fertilizer both rubber tree growth and nutrition required for stimulation elements. It has the characteristics of high utilization rate of nutrients and easy absorption of crops, and has obvious effects in promoting the growth of rubber trees, stimulating gel discharge and controlling the development of dead skin disease. The chelated rare earth molybdenum fertilizer stock diluted with water to a concentration of 0.2 to 2.0%, in the tapping period applied to the tapping mouth and tapping surface, 1 to 2 times a month, coated 5 to 10 times, the net yield of up to 8.6 ~ 37.6%. Mixture with ethephon better. Chelated rare earth molybdenum fertilizer in the rubber tree on the application of convenient, less dosage, significant economic benefits, has broad prospects for development.
