What should you pay attention to when fertilizing a warm solar greenhouse? First, pay attention to whether the fertilizer is qualified, whether it is suitable for the growth of the crop. It is necessary to determine the fertilizer required for the crop. Pay attention to the following points in the fertilization process:
1. Although the organic fertilizer has a low content of fertilizer elements, it contains the most comprehensive fertilizer elements and also contains a large amount of organic matter.
2. Adding organic fertilizer can not only meet the demand for various fertilizer elements in winter-heated solar greenhouse crops, but also significantly increase the organic matter content of the soil.
3. Winter warm solar greenhouses must be topdressed on sunny days and open vents. Ditching, dredging, digging, covering, watering, and film covering must be carried out simultaneously.
Finally, greenhouse manufacturers remind you that it is strictly forbidden to topdress on cloudy days or in the afternoon. The application of chemical fertilizer must be carried out in combination with watering, about 0.3 kg per ditch, first dissolved into an aqueous solution, and then washed with water.
