What changes have been brought to agricultural life by the development of modern science and technology

    First, it changed the natural production conditions of agriculture. For example, improving soil, using greenhouses to change heat conditions, construction of water conservancy projects, and changing water source conditions. Secondly, it changed the social and economic conditions of agriculture, such as the invention of the freezer boat, which allowed Argentine beef to be sold to Europe, and fresh-keeping technology enabled Dutch tulips to be sold in the Hong Kong market. In addition, the irrigation technology has been improved so that the agricultural products of Israel in the tropical desert climate can not only be self-sufficient, but can also be exported. Improved varieties have been bred, which has improved the production and the ability to resist diseases and insect pests.

     The new growth points that combine science and technology with agricultural production are mainly concentrated in the following aspects:

     1. Modern breeding technologies will continue to provide excellent sources for agricultural production: physical and chemical mutation breeding technologies will provide breeders with a large number of mutant strains for their breeding.

     2. The application of modern bioengineering technology, genetic engineering and genetic engineering in breeding will enable breeders to directly introduce relevant genes to produce good varieties according to breeding goals. For example, the salt-tolerant target gene is introduced into the forage grass, so that it can be cultivated into a salt-tolerant forage grass variety, so that the saline-alkali land and the desert are expected to become pastures full of cattle and sheep.

     3. The recent birth of animal cloning technology has greatly advanced the technology of cultivating excellent breeds of animal husbandry. With the success of distant hybrid breeding technology, the heterosis in hybrid breeding will become more obvious. The contribution of modern science and technology in breeding will become the most important field of agricultural development.

    4. The production technology of agricultural protected areas will provide people with more exquisite and high-quality agricultural products: With the improvement of people's living standards, the requirements for the quality of agricultural products are getting higher and higher. Off-season foods, green foods, etc. have been introduced one after another, and the production of these results is based on the maturity, popularization and application of agricultural protected land production technology.

    5. The production technology of agricultural protected areas concentrates the research results of many scientific and technological researches, such as plant water and fertilizer management, photosynthesis, plant flower physiology, plant growth regulating substances, plant stress resistance, plant ecology and so on.

     6. The application of protected land production technology not only provides people with high-quality agricultural products, but also greatly improves the economic benefits of producers.

    7. The application of plant tissue culture technology will greatly accelerate the propagation and promotion of new and excellent varieties: The rapid plant propagation technology that has matured and begun to be used in production practices can reproduce a large number of new varieties of plants in a short period of time. Seedlings greatly shorten the promotion process of improved varieties. The virus-free vaccine produced by plant virus-free technology will greatly improve the yield and quality of crops.
