我局于1975年和华南热作研究院联合用草甘膦在所属几个国营农场的橡胶园布置多点除草试验,研究有关使用技术。在此基础上近年已扩大到十一个农场大面积胶园推广使用。到今年施药面积约12000亩,获得药效好、工效高、成本低的效果。通过几年实践认为,草甘膦具有广谱、高效、安全等特点,是目前毒杀茅草、香附子、硬骨草、大芒等深根性恶草和控制胶园一般性杂草生长比较理想的除草剂。现将有关试验与大田使用技术总结如下。
In 1975, our bureau and the South China Research Institute of Hot Work combined with glyphosate in the rubber plantation of several state-owned farms to arrange more weeding experiments to study the use of technology. On this basis, in recent years, it has expanded to a large area of 11 farms to promote the use of plastic. To this year the area of about 12,000 acres of pesticides, access to good efficacy, high efficiency, low cost effect. After several years of practice, glyphosate has the characteristics of broad spectrum, high efficiency, safety and so on. It is ideal for the general weeds to control deep weeds such as thatch, Cyperus rotundus herbicide. Now the test and field use of technology are summarized below.
