螟虫、蓟马和杂草是影响本区稻苗早发壮苗夺高产的大害,而此时各项防除工作正处于大忙季节,稍不协调,常常顾此失彼,影响水稻稳产高产。1980年我们试用“三合一”毒(肥)土法,综合治理苗期害虫和杂草500多亩,取得了较为理想的效果。我们以麦茬稻为重点,在栽秧后5—7天,将“三合一”毒 Stem borers, thrips, and weeds are the major harms that affect early seedling emergence and seedling emergence in this region.

In 1980, we experimented with the “three in one” poison (fertilizer) soil method, comprehensive treatment of 500 mu of seedling pests and weeds, and achieved satisfactory results.
