Now in winter, temperatures are declining, but the overall market demand for vegetables is still very high, and vegetable cultivation in the sheds is widely used by farmers to meet market demand. During the winter, planting in the sheds is carried out in an environment and at an appropriate temperature, the quality of the vegetables grown is ensured, and proper fertilization and watering in the sheds also contributes to vegetable growth. What then needs attention to grow vegetables in the sheds during the winter。
I. Temperature and humidity
During the winter, large temperature differentials in the greenhouses, combined with short daylight periods, made it difficult to stabilize the temperature within the greenhouses. At this point, we can use heating equipment and thermostats to regulate temperature. If the temperature is too high, ventilation is required to cool and appropriate humidity is maintained。
Ii. Watch the light
The short duration of light in winter greenhouses and the weakness of light make it necessary to select vegetables suitable for winter planting, such as seedlings, celery, lettuce, etc. At the same time, good ventilation in the greenhouses should be maintained and the sun should be projected straight into the vegetables as much as possible。
Iii. Attention to irrigation
Vegetables are growing slowly in winter greenhouses, with relatively little water consumption, and adequate control of irrigation is required. Excessive moisture can lead to oxygen deficiency and root decay in the roots of vegetables, seriously affecting their growth。
Iv. Pest and disease prevention
Air moisture is high in winter greenhouses and vegetables are vulnerable to fungi and bacterial infections and require regular spraying of microbicides. At the same time, care must be taken to combat the pests of vegetables by choosing non-toxic, non-polluting methods to ensure the quality and safety of greenhouse vegetables。
This is what the south bulk integrated and innovative service platform has to do with vegetable production in winter. It is to be hoped that it will be of assistance and welcome to discuss it more often. At present, many research units have been established in the country's southern breeding area, which is located in sanya city's cliff region and is climate-appropriate and in favourable soil conditions, providing good conditions for southern breeding. The zone has advanced scientific facilities and instruments, has a strong scientific capacity, is an important integrated agricultural genetically modified crop breeding area in the country, and is the country's designated main field testing base for genetically modified breeding。
In the area of living, the southern multi-innovative services platform (http://www. Nfxpt. Com/) provides a full range of services for southern researchers, including production, life, scientific research, land applications, etc. In the area of life, the southern multi-innovative services platform provides food and housing services, providing a comfortable living environment for scientific researchers. In the area of production, the southern multi-innovative services platform provides a range of production-related services, such as ploughshares, and facilitates the production of scientists。
