在三麦生产中，导致产量不高不稳的主要制约因子之一是渍害，不同地区常年产量徘徊在每公顷2962．5公斤。自1992年秋播前夕，我市在不同地区不同土壤类型的农田上展开了埋设塑料暗管的试验示范研究，几经实践应用表明，暗管在农业生产中的作用明显，效益显著。它是解决麦田渍害
In Sanmai production, one of the main constraints that led to the problem of low output and unstable production is that the perennial output in different areas has hovered at 2962.5 kilograms per hectare. Since the autumn of 1992 autumn eve, the city in different regions of different soil types of farmland embarked on plastic pipe embedded in the pilot demonstration study, after several practical applications show that the role of underground pipe in agricultural production is obvious, significant benefits. It is to solve the wheat stains
