二年三作旱地机械化保护性耕作的研究与实践

Research and Practice of Dry Land Mechanized Protective Farming Method of Two-year-three-crop System

论证了创建并实施二年三作旱地机械化保护性耕作技术体系,不但能最大限度地发挥土地效益,减少病虫害的发生,而且能有效改善土壤的水、肥、气、热生态环境,提高地力等级,增产幅度较大,具有很高的实用和推广价值。

This paper demonstrates that the establishment and practice of the d ry land mechanized protective farming method of two-year-three-crop system ca n not only give full play to the earth benefit and reduce the insect pest, but a lso effectively improve the water, fertilizer, gas and thermal environment and i ncrease the level of the land capacity, and by using this method can get higher amount of the increase in production, and possesses very high practical and popu larizing value.
