China is a major agricultural country. As a primary industry, the development of agriculture is directly related to national economy and people’s livelihood. In the development of traditional agriculture, due to the reliance on manpower, there are strong limitations in crop types, yields and other aspects. The development of agriculture is inseparable from the support of science and technology. If we can make full use of science and technology to promote and spread agricultural knowledge and apply it to specific agricultural production, not only can more agricultural workers understand the relevant technology to achieve the effect of technology promotion and popularization, but also can effectively improve the efficiency of agricultural production and reduce the degree of human labor.
In addition to agricultural technology development and basic theories, this book also focuses on the whole process of agricultural breeding, planting, growth, management from the aspects of genetic improvement of crops, crop planting, agricultural technology service mode and mechanism, agricultural operation and management, and quality and safety management of agricultural products in China. Also, it summarizes the experience of technology and management from traditional agriculture to modernization and mechanization in China. It is a rare agronomy tool book suitable for popularizing agricultural technology.
