１９８７～１９９０年对免耕、少耕（浅旋耕）、常规耕的稻茬麦田杂草发生特点进行了研究。结果表明，３种耕法麦田杂草群落中，禾本科杂草（看麦娘、硬草）为优势种，群落中的杂草种类无变化，但免耕使田间杂草群落类型向有利于禾本科杂草的方向发展。３种耕法麦田杂草发生动态呈一致性，表现为冬前一个主出草高峰，次年春季一个次高峰。但免耕麦田杂草发生的时间早、数量多、出草主高峰明显，草量约为耕翻田的２倍，出草时间也比耕翻田早５～７ｄ，出草高峰相应提前。在３种耕法的麦田中，以０～５ｃｍ表土层可萌发杂草种子分布的比例为最高。免耕麦田的可萌发杂草种子集中分布在０～５ｃｍ的表土层中，少耕麦田可萌发杂草种子主要分布在０～５，５～１０ｃｍ的土层中，而常规耕麦田的可萌发杂草种子在耕作层中分布比例趋向接近。
From 1987 to 1990, we studied the characteristics of weeds in the no-tillage, tillage (shallow-tillage) and conventional tillage rice fields. The results showed that grass weeds (hardweed) and grass weeds were the dominant species in the weed communities of the three kinds of tillage cultivars, but there was no change in the weed species in the community. However, Gramineous weeds in the direction of development. The dynamics of weeds in the three tillage cultivars were consistent, showing the main peak of grass weaving before winter and the next highest peak in the following spring. However, tillage occurred in tillage tillage in a time-consuming manner and with a large number of trees. The main peak of grass weeding was obvious. The amount of weeds was about twice as high as that of tillage and the planting time was 5 to 7 days earlier than that of tillage. Among the three kinds of tillage wheat fields, the distribution of weed seeds with 0 ~ 5 cm topsoil was the highest. The seeds of germinable weed in tillage wheat fields were concentrated in the topsoil of 0-5 cm. The seeds of germinable weeds in less-tillage wheat fields were mainly distributed in the soil layer of 0-5.5-10 cm while those of conventional tillage fields could germinate The proportion of weed seeds in the tillage layer tended to approach.
