Preface

Agricultural mechanization is an advanced mode of production, which can effectively improve the rural economy. Protective cultivation is an advanced farming method and a sustainable farming mode. Agricultural mechanization and protective cultivation are interdependent and inseparable. Accelerating both the agricultural mechanization and the development of protective cultivation is an important task in China’s agricultural development.
  Agricultural Mechanization means that the whole process of agricultural production is completed by machinery, which aims to improve labor productivity and land productivity. In recent years, the rapid development of Agricultural Mechanization in China has reduced the labor intensity of farmers, improved the efficiency of agricultural production, solved the problem of rural labor shortage and played a vital role in the rapid development of agriculture in China. However, the rapid development of agricultural mechanization has also brought some problems to the land environment. Agricultural machinery’s deep ploughing and wasteland reclamation have led to serious soil erosion and environmental deterioration. Therefore, it is necessary to popularize protective cultivation technology. Protective cultivation can achieve the goal of no tillage and less tillage by adopting mechanized cultivation. Protective cultivation and agricultural mechanization are interdependent and supplementary to each other. The combination of them can simplify the farming mode, reduce costs, increase economic benefits and achieve sustainable development. Protective cultivation and agricultural mechanization can also effectively reduce agricultural costs and improve food production, which needs to be vigorously promoted in rural areas of China.

前 言

农业机械化是一种先进的生产方式，能够有效的提升农村经济。保护性耕作是一种先进的耕作方式，是一种可持续发展的耕作模式。农业机械化和保护性耕作相互依赖，密不可分。加快农业机械化的同时大力开展保护性耕作是我国农业发展的重要任务。
      农业机械化是指农业生产的全过程都使用机械来完成，目的是提高劳动生产率和土地生产率。近年来，我国农业机械化的发展突飞猛进，减轻了农民的劳动强度，提高了农业生产效率，解决了农村劳动力短缺等问题，对我国农业的飞速发展起到了至关重要的作用。但农业机械化迅速发展的同时，也给土地环境带来了问题，机械化深耕深翻、开荒种地导致水土流失严重、环境恶化。为此，需要大力推广保护性耕作技术。保护性耕作通过采用机械化的耕作方式，从而达到免耕、少耕的目的。保护性耕作与农业机械化相符想成、互相依靠，可以简化耕作模式，降低成本，调高经济效益，同时能够起到可持续发展的效果。保护性耕作和农业机械化也能够有效的减低农业成本，提高粮食产量，需要在我国农村地区大力推广。
