一、稻茬免耕麦的发展江苏省稻茬免(少)耕麦经历了六十年代“懒种麦”、七十年代“抗灾麦”和八十年代“增产麦”三个阶段。早在六十年代初期,部分地方就在水稻田里发展套播免耕麦,当时是从茬口紧、季节晚和播种省工节本出发,由于配套措施跟不上,套播时间偏早,苗期管理质量差。产量不理想而停止了。七十年代以后,各地农民为了抗御稻茬土质粘重,适耕期短,耕作困难和烂耕烂种等灾害,又重新发展了免耕麦。但由于当时对免耕的作用认识不一致,这项改革也没有发展起来。直到八十年代以后,各地通过反复实践,证明它具有增产节本的效果,因而统一了对免耕作用的认识,加快了示范推广的步伐。现在全省免(少)耕麦的面积已达1,618万亩,占稻茬麦面积
First, the development of rice stubble tillage wheat Jiangsu Province stubble free (less) tillage experienced the sixties “lazy wheat”, the seventies “disaster wheat” and the eighties “increase wheat” three stages. As early as the early 1960s, no-till wheat was planted in paddy fields in some parts of the country. At that time, it started with stubble, late seasons and sowing provinces. Due to the lack of supporting measures and the slow-seeding time, Poor seedling management. Yield is not satisfactory and stopped. Since the seventies, all local farmers have re-developed the no-tillage wheat in order to resist the disastrous soil quality of the rice stubble, short period of suitable cultivation, hard farming and rotten and rotten cultivars. However, due to the inconsistent understanding of the role of no-till at that time, the reform did not develop. It was not until the 1980s that various localities proved that they had the effect of increasing production and saving costs through repeated practice, thus unifying their understanding of the role of no-tillage and accelerating the pace of demonstration and extension. Now the province free (less) area of cultivated wheat has reached 1,618 mu, accounting for the area of rice stubble
