赵畯田博士在广州作了一系列有关甘蔗土壤肥料方面的学术专题报告,并和与会代表进行了座谈、讨论。主要内容概述如下:1、在“现代科学技术在甘蔗农业生产上的应用”的专题报告中,赵博士谈了甘蔗生产的特点、影响甘蔗生产的因素,认为搞好甘蔗生产有技术上的问题,也有管理上的问题,必须正确运用现代科学技术(包括管理技术)来解决甘蔗生产上的各个问题,推进甘蔗生产的发展。从长远计,还应注意防止在采用科学技术时可能引起的环境污染问题。2、在“土壤化学性质和甘蔗合理施肥的关系”的专题报告中,赵博士强调了解土壤化学性质是合理施肥的必要前提,同时详细阐述了甘蔗生长必需的各种主要元素、次要元素和微 Zhao Zhaotian made a series of academic presentations on sugar cane soil fertilizers in Guangzhou and held discussions and discussions with the participants. The main contents are summarized as follows: 1. In the special report of “Application of Modern Science and Technology in Agricultural Production of Sugarcane”, Dr. Zhao talked about the characteristics of sugar cane production and the factors that affect the production of sugarcane. He thought that there are technical problems in sugarcane production , There are also management problems. We must correctly use modern science and technology (including management techniques) to solve various problems in sugar cane production and promote the development of sugar cane production. In the long term, attention should also be given to preventing possible environmental pollution caused by the use of science and technology. In his special report on the relationship between chemical properties of soil and reasonable fertilization of sugarcane, Dr. Zhao emphasized that understanding the chemical properties of soils is a necessary prerequisite for rational fertilization. In addition, he elaborates on the major elements and minor elements necessary for the growth of sugarcane micro-
