发达国家旱地作物免耕少耕迅速兴起加速了我国稻田免耕的研究和尝试。随着新的高效、低毒除草剂的出现,为稻田完全除去犁翻耕耙的免耕抛秧技术创造了基础。近几年,广东省农业科学院水稻研究所提出并广泛推广的水稻抛秧技术已为农民解决了拔秧、插秧两弯腰问题,大大地减轻了劳动强度,提高了工效。现在该所更提出了一套免耕技术,以适应解决我省农业生产所存在的稻田面积缩减,耕牛、拖拉机的减少和水稻生产经济效益下降等问题。该所研究人员在番禺、东莞、高要、曲江、新兴等地进行大田试验,均获成功。直接板田免耕抛秧较之传统耕作的插秧或抛秧有许多优点:第一,不用犁耙田,每亩减少犁耙办田支出
The rapid rise of dry land cultivation without tillage in developed countries has accelerated the study and attempt of no-tillage in paddy fields in China. With the advent of new high efficiency, low toxicity herbicides, the foundation for no-tillage and sowing techniques for complete removal of plow tillage harrows in paddy fields has been established. In recent years, Rice Research Institute of Guangdong Academy of Agricultural Sciences put forward and widely popularized rice throwing technology has solved the peasants pulling rice, transplanting two bending problems, greatly reducing the labor intensity and improve work efficiency. Now the institute has proposed a set of no-till technologies to solve the problems of the reduction of paddy field area, the reduction of cattle and tractors and the decline of economic benefits of rice production in the agricultural production in our province. The researchers in Panyu, Dongguan, Gaoyao, Qujiang, emerging fields such as field trials, were successful. Direct paddy field no-tillage throwing than traditional farming transplanting or throwing transplanting has many advantages: First, do not have rake fields, reduce the amount of rake per mu field operations
