目前,世界上绝大多数植胶国家都在应用叶片和土壤分析的结果,诊断橡胶树施肥。由于常规的叶片、土壤分析法费时、费力和费钱,印度大量的分散的小胶园要基于这种分析法适时地提供施肥推荐,有实际的困难。因之,进行了使用Kit比色计作叶柄和土壤快速分析法的研究,本文提出了研究结果。结果表明快速分析法是诊断胶园施肥的有用手段,特别适用于小胶园。 已经肯定,植胶的热带地区大部份土壤缺乏植物所需要的营养成分,必须施肥。一些国家研究者报导:不经任何诊断的定期施肥,有时不但浪费肥料,还导致胶树生长迟缓和产胶量下降。 由于近年来化肥价格很贵,施肥已成为我国植胶成本中最花钱的项目之一。这就不可避免要弄清楚,以通过最小的肥料投资得到最大的收益。在这方面已经提到所有的主要植胶国家已经普遍采用由有代表性的土壤和叶片样品的分析结果,判断土壤和胶树的营 养状况,以便对胶树对症施肥。几年前,印度也开始采用这种措施,但到目前为止,仅限于少数种植园采用。 印度橡胶业由120,000个种植园组成,其中99％为小胶园,分布范围很广。因此,对小胶园提供基于叶片和土壤分析的施肥推荐,是一项艰巨的任务。土壤叶片的常规分析费时、费力又费钱、不能适应小胶园的需要,这是行不通的。所以应当强调采用由土壤和叶? At present, most of the world’s plasticized countries are applying the results of leaf and soil analysis to diagnose rubber tree fertilization. Due to the time-consuming, labor-intensive and expensive soil analysis methods of conventional leaves, a large number of dispersed small rubber plants in India have to provide timely and recommended fertilization recommendations based on this method of analysis, with practical difficulties. Therefore, the use of Kit colorimeter for rapid analysis of petiole and soil research, the paper presents the results. The results show that the rapid analysis method is a useful tool to diagnose the rubber plantation fertilization, especially suitable for small rubber plantation. It has been affirmed that most of the soils in the gummed tropical areas lack the nutrients needed by the plants and must be fertilized. Some national researchers have reported that regular fertilization without any diagnosis, sometimes not only wasted fertilizers, but also led to delayed growth of gum trees and a decrease in the amount of gum produced. Due to the high price of fertilizer in recent years, fertilization has become one of the most expensive items in the cost of plasticizing in our country. This inevitably needs to be clarified in order to get the maximum benefit from the minimal fertilizer investment. It has been mentioned in this context that all the major seeding countries have generally adopted the analytical results from representative soil and leaf samples to determine the nutritional status of soils and gum trees in order to symptomatically fertilize gum trees. A few years ago, India began to adopt this measure, but so far it has been limited to a few plantations. The rubber industry in India is made up of 120,000 plantations, 99% of which are small-scale, with a wide distribution. Therefore, it is a daunting task to provide fertilizing recommendation based on blade and soil analysis to the small rubber plantation. Routine analysis of soil leaves is time-consuming, laborious and costly and can not be adapted to the needs of a small plantation. This will not work. So it should be emphasized that by the soil and leaves?
