Let greenhouses have sustained productivity
The 21st century is the century of biotechnology, and agriculture is the main application of biotechnology. In recent years, biotechnology has become more and more widely used in various fields of agriculture, and it has penetrated almost every field, such as breeding, pesticides, fertilizers, etc. In this paper, the winter greenhouse vegetable cultivation is taken as an example to briefly explain the application of biotechnology in greenhouses. . The appearance of greenhouses has greatly enriched the residents' dining tables and caused the emergence of anti-seasonal foods. For example, in the winter, we can eat cucumbers, tomatoes and other fruits and vegetables that were eaten in the past. However, the greenhouse is a closed, small system. Management must be strict, or various diseases will occur, affecting the yield and quality. However, these problems can be well avoided if biotechnology is used comprehensively.
The main problems that often plague users in greenhouses are: winter heating problems in greenhouses and piles of garbage disposal during the season. In winter, the temperature is generally low. In order to maintain normal production of greenhouses, heating and heating facilities must be available. In the past, conventional heating methods include heating by electric lines and heating by hot air ovens. However, these methods waste energy, increase costs, and cause inconvenience. Biotechnology, namely straw bioreactor technology, can not only solve the problem of warming and heat preservation in greenhouses, but also make full use of excess crop straw waste and solve agricultural garbage.
