我国北方粮田的种植制度多是一年两作或二年三作,秋收作物收获后播种冬小麦。每当三秋(秋收、秋耕、秋种)季节,农活集中,时间紧迫,部分麦田因误期晚播造成减产。如何简化麦田耕作技术,争取时间多种适时小麦,是小麦增产的关键措施之一。据国外研究,在耕作制度上,少耕和免耕可以节约能源,降低生产成本,还有利于合理利用和提高土壤肥力,有些国家已把少耕免耕技术应用于多种作物上,取得了明显的增 The cultivation system of grain crops in the north of our country is mostly done in two or three years in a year, and winter crops are harvested after harvest in autumn. Whenever three autumn (autumn harvest, autumn farming, autumn species) season, concentrated farming, time is tight, part of the crop due to late delivery caused by a decrease of production. How to simplify the wheat farming techniques and strive for a variety of timely wheat is one of the key measures to increase wheat yield. According to foreign studies, in the farming system, less tillage and no-tillage can save energy, reduce production costs, but also conducive to rational use and improve soil fertility, some countries have put tillage and no-tillage technology applied to a variety of crops, made Obvious increase
