Five suggestions for improving the efficiency of greenhouse

For famers it is the big profits that attract them to invest the greenhouses. But some friends said that the greenhouse couldn’t play well use in greenhouse crop growth over the next few years than expected. So how can we improve the utilization rate of the greenhouses? We have the following five Suggestions.
1>. Replacement of planting methods and varieties:
In order to make great benefits, it is better to improve cultivation and varieties in greenhouse growing after a same species of crop growing a few years in a greenhouse, such as grafting, continuous cropping cucumber. If other varieties were grafted, it can prevent the occurrence of various diseases, increasing rate of over 30%.
2>. Using anti-drop film
Using the PE anti-drop film could prevent the greenhouse moisture be condensed into water droplets on the plastic film, avoiding shading effects for the greenhouse plants. If the transmittance rate could be about 90%, the crop photosynthesis can be guaranteed.
3>. Soil disinfection
Because the crops in the greenhouse were planted continuously, more general diseases would be happened. Therefore, the soil should be disinfected to prevent insect infection spread.
4>. Using double layer heat preservation
It had better to use double layer heat preservation measure in order to ensure normal crop growth in the greenhouse in winter, which cover the film with mulch or set a arch film to receiving good effects.
5>. Spraying rare earth liquid
If your greenhouse was used to grow solanaceous fruit vegetables, you could try to spray concentration 0.2% to 0.5% rare earth nitrate solution at the beginning of flower state, which can effectively improve crop yield and crop quality.
