Methods of Improving the Utilization Rate of Steel Frame Greenhouses
The use of steel-frame greenhouses is naturally to improve products and efficiency. The higher the utilization rate of steel-frame greenhouses, the more users will like them and feel that steel-frame greenhouses are worth using. Here are some ways to improve the utilization rate of steel frame greenhouses:
① Change the planting method and variety:
After the same species of crops are planted in the greenhouse for several years, if we want to improve the benefits to a higher level, we must work hard on planting and species. For example, if grafting is used to continuously grow cucumbers in steel-frame greenhouses, if other varieties are used for grafting, it can prevent the occurrence of various diseases and increase the yield by more than 30%;
② Switch to non-drip film:
With the polyethylene non-drip film, the water vapor in the steel frame greenhouse will not condense into water droplets on the film, which will not have a shading effect on the crops in the steel frame greenhouse. If the light transmittance of the steel frame greenhouse can be maintained at 90% Left and right, the photosynthesis of crops can be guaranteed;
③Soil:
The crops in steel-frame greenhouses are usually more severely affected by continuous cropping, so it is necessary to kill the germs that spread through the soil;
④Using double-layer insulation:
In order to allow the crops in steel-frame greenhouses to grow normally in winter, it is better to adopt double-layer insulation measures, that is, to cover the steel-frame greenhouse with plastic film or set up a small arch shed, which can achieve good results.
