近几年来,湖南和广西等省,栽培紫云英与苕子,已开始大面积施用根瘤菌剂。这对提高綠肥产量和保証新区綠肥种植成功,都起了很显著的作用。但是,我們通过多年的实践体会和向各地进行調查了解后,認为不少地区在綠肥根瘤菌剂的施用技术上还存在若干問題。而这些問題都直接或間接影响到菌剂施用的效果,因此急待提高改进。現将几个主要問題分述于下,幷作一些初步討論,以供各地参考,且希指正。
In recent years, Hunan and Guangxi provinces, cultivation of milk vetch and razor clam, has begun large-scale application Rhizobium agents. This has played a significant role in improving green manure production and ensuring the success of green manure cultivation in the new area. However, after years of practical experience and surveys conducted by various localities, we believe that there are still some problems in the technical application of green manure rhizobium in many areas. These problems have a direct or indirect impact on the effectiveness of the application of the bactericide, so an urgent improvement is needed. We will now outline some of the major issues under discussion and make some preliminary discussions for reference and guidance.
