Requirements of greenhouse for rice seedling, such as environmental requirements, temperature, humidity, co2, light, etc. What are the specific parameters?

The standard greenhouse for rice seedling raising with steel frame is 60m× 6-6.5m× 2.3-2.4m. The seedling raising area of each greenhouse can be inserted into 50-55mu of Honda land.

The suitable scale of centralized seedling raising field is 30-50 greenhouses per base.

The main contents of greenhouse rice seedling management signs are as follows: the highest, optimum and lowest temperature indexes in each stage of rice seedling management are 20 degrees in spring and summer, 30 degrees in summer and autumn, and 40 degrees in autumn and winter; Water management indicators and watering standards in each period; Management indicators such as weeding and disease prevention in rice fields.

After seedling management, we should also pay attention to ventilation and hardening seedlings to prevent them from burning. Pay attention to watering during drought to prevent salt return from affecting the growth of rice seedlings. Fertilize according to seedling conditions to ensure Miao Zhuang. Seedlings can be transplanted when they reach the age of three leaves and have a heart shape. The seedling age is generally about 30 days.
