How to prevent greenhouse hollow celery

In the production process of celery in the solar greenhouse, hollow phenomenon often occurs, resulting in the increase of cellulose in celery, deterioration of quality, and decline in yield, which in turn affects the income of vegetable farmers. So, what management measures should be taken in production? Science watering, grasping suitable temperature. Many times of watering will cause the soil temperature to drop, which will affect the normal growth of celery, resulting in the lack of sufficient water supply for the growth of celery. Generally, water should be poured once every 15 days. The amount of water should not be too large. During the period of strong growth, sufficient water supply should be ensured. Water should be sufficient for about 15 days before harvest. Planting in the greenhouse, the daytime temperature of 15 ~ 23 °C is appropriate, at night should be maintained at 10 °C the best. Spraying new high-fat membranes to prevent moisture evaporation, insulation and freezing, isolation of pests and diseases, can effectively avoid hollow. On the basis of applying base fertilizer, the top-dressing fertilizer in the growing season was sprayed with foliar spray with a new high-fat film + vegetable strong stem + 0.3% ~ 0.5% borax solution and sprayed once every 15 days. Appropriate harvest has a significant effect on the prevention of the occurrence of the hollow disease.

Fiberglass Grating

Fiberglass Grating

The fiberglass grating also named FRP grating & fiberglass grid, and the fiberglass grating panels can be made into FRP grating cover, fiberglass walkway grating, fiberglass trench grating and so on.

The fiberglass grating is light in weight and has good elasticity, so it can be cut freely during the installation process, without using lifting equipment, and only a small amount of labor and cutting tools are required. Because the FRP grid is made of non-metallic materials, the corrosion resistance of the FRP grid is very good. The FRP grid will not rust and rust under the chemical medium, nor will it damage the structure of the material.

Beyond that, the color of fiberglass grating including yellow, gray, green and as your demands.
