水稗草为水田中危害最大的一种杂草,随着水田面积的扩大,设法防除这种杂草有着重大的意义。根据东北农业科学研究所1957年的调查研究报告,和佳木斯农业试验场1956年的报导,深水淹稗对于防除这种杂草有着一定的效果。深水淹稗是一项简而易行的有效灭稗措施,但在实行中必须掌握适当的水温,水层及浸淹持续日数等因素,不然就会使淹稗的效果降低或过多的造成稻苗死亡。本试验的研究目的就是在于阐明这些因素对淹稗的效果及对稻苗损伤的关系。
Water barnyardgrass is the most harmful weed in the paddy field. With the expansion of the paddy field, it is of great significance to try to control this weed. According to the 1957 research report of Northeast Agricultural Science Institute and the report of Jiamusi Agricultural Experimental Station in 1956, the deep-water flooded barnyardgrass has a certain effect on controlling this weed. Barnyard grass is a simple and effective measure to combat barnyard grass. However, proper water temperature, water layer and the number of days of flooding must be controlled in practice. Otherwise, the effect of barnyard grass will be reduced or excessive. Rice seedlings die. The purpose of this study is to elucidate the effects of these factors on flooded barnyardgrass and the damage to rice seedlings.
