Five Suggestions for Improving Greenhouse Efficiency
For farmers, it is the large profits that attract them to invest in greenhouses. However, some friends said that in the next few years, the greenhouse might not be as effective in promoting greenhouse crop growth as expected. So, how can we improve the utilization rate of greenhouses? Here are five suggestions.
1. Replacement of Planting Methods and Varieties:
To achieve greater benefits, after growing the same crop species in a greenhouse for a few years, it is advisable to improve cultivation techniques and varieties in greenhouse growing. For example, in the case of continuous cropping cucumber, grafting can be used. If other varieties are grafted, it can prevent the occurrence of various diseases, increasing the yield by over 30%.
2. Using Anti - Drop Film
Using the PE anti - drop film can prevent the moisture in the greenhouse from condensing into water droplets on the plastic film, thus avoiding shading effects on greenhouse plants. If the transmittance rate can reach about 90%, the crop photosynthesis can be guaranteed.
3. Soil Disinfection
Since crops in the greenhouse are planted continuously, more common diseases are likely to occur. Therefore, the soil should be disinfected to prevent the spread of insect - borne infections.
4. Using Double - Layer Heat Preservation
It is better to use double - layer heat - preservation measures to ensure the normal growth of crops in the greenhouse during winter. Covering the film with mulch or setting up an arch film can achieve good results.
5. Spraying Rare - Earth Liquid
If your greenhouse is used to grow solanaceous fruit vegetables, you can try spraying a 0.2% - 0.5% rare - earth nitrate solution at the beginning of the flowering stage. This can effectively increase crop yield and improve crop quality.
