**Application of New Technology for Increasing Production of Fruits and Vegetables**
- Explain the new technology for increasing temperature and increasing production in greenhouses
**Keywords:** greenhouse warmer, straw bioreactor, microbial, carbon dioxide, temperature
Traditionally, it was believed that the main "food" for plants like fruits and vegetables came from fertilizers. The idea was that by increasing the amount and quality of fertilizer, crop yields could be boosted. However, modern plant nutrition theory suggests a different approach: plants do not grow by consuming fertilizer, but by absorbing carbon dioxide, water, and light. Fertilizer is more of a supplement, providing essential minerals, while the absence of COâ‚‚, water, and light would lead to plant starvation.
Based on this understanding, methods to increase yield and quality now focus on boosting COâ‚‚ levels, improving water conditions, optimizing fertilizer use, and managing light exposure effectively.
This has led to the development of **greenhouse biological warming technology**, which uses microbiological engineering to enhance greenhouse temperature, heat retention, and productivity. This method, also known as **straw bioreactor technology**, involves using crop straw in reactors to generate carbon dioxide, heat, and beneficial microorganisms through biological reactions.
### Greenhouse Biological Warming Technology
This technology is built on four key theories: the **plant hunger theory**, **leaf active and passive absorption theory**, **plant bio-control theory**, and the **recycling of mineral elements in straw**. By combining these concepts with bio-engineering techniques, it transforms crop residues and manure into gas, heat, and nutrients required for plant growth, leading to high-yield, high-quality, and eco-friendly agricultural products.
#### (1) Plant Hunger Theory
The theory suggests that many common plant issues—such as fruit deformities, poor color, low sugar content, and weak resistance—are caused by a lack of essential elements, especially carbon dioxide. Traditional farming often overemphasizes chemical fertilizers while neglecting the importance of CO₂. Straw bioreactors help address this by increasing CO₂ levels 4–6 times, significantly improving plant health and productivity.
#### (2) Leaf Passive Absorption Theory
Plants absorb COâ‚‚ through their leaves via both active and passive processes. Based on this, **built-in** and **external straw bioreactors** have been developed to boost COâ‚‚ concentration, raise ground temperature, and enhance crop yield. For example, **Gumbaum greenhouse warmers** are built-in systems that use microbes to convert straw into COâ‚‚ and heat.
#### (3) Plant Bio-Control Theory
This theory emphasizes the use of beneficial microorganisms to suppress pathogens. Microbes in the bioreactor produce enzymes and organic acids that inhibit harmful bacteria, reducing the need for chemical pesticides. This leads to healthier crops and fewer environmental impacts.
#### (4) Recycling of Mineral Elements in Straw
Straw and other organic waste can be transformed into valuable nutrients through microbial activity. This process regenerates COâ‚‚, water, and minerals, while also producing disease-resistant spores. It helps reduce the need for chemical fertilizers and improves soil structure and fertility.
### Benefits of Straw Bioreactors
Using straw bioreactors offers several advantages:
1. **CO₂ Enhancement**: Increases CO₂ levels by 4–6 times, boosting photosynthesis and reducing water usage by up to 300%.
2. **Temperature Rise**: Raises ground temperature by 4–6°C and air temperature by 3–5°C, extending the growing season by about 30 days.
3. **Biological Pest Control**: Reduces pesticide use by over 60%, promoting eco-friendly farming.
4. **Soil Improvement**: Enhances soil structure, nutrient content, and water retention, reducing reliance on chemical fertilizers.
### How to Make a Bio-Warming Greenhouse
One effective product in the market is the **Goldbom greenhouse warming agent**, developed by Beijing Huaxia Kangyuan Science and Technology Co., Ltd. This microbial-based product uses advanced biotechnology to convert straw and organic waste into COâ‚‚, heat, and nutrients.
To implement this system:
1. **Soil Preparation**: Remove stubble, add decomposed farmyard manure, and mix with compound fertilizers.
2. **Trenching**: Create trenches of specific dimensions and prepare the soil.
3. **Fermentation Agent Preparation**: Mix the microbial starter with wheat bran, water, and urea to activate the bacteria.
4. **Straw and Fertilizer Application**: Layer straw in the trench, add the fermentation mixture, and cover with soil.
5. **Irrigation and Covering**: Water the area thoroughly and ensure proper coverage to maintain moisture and temperature.
6. **Planting and Ventilation**: Drill holes for seedlings and allow COâ‚‚ to escape for better air circulation.
### Results and Maintenance
Farmers who use this technology report an average yield increase of 30–50% per acre, with a strong return on investment. The quality of fruits and vegetables improves significantly, with better taste, color, and shelf life.
Maintenance tips include keeping the soil layer thin (under 20 cm), reducing watering frequency during winter, and adjusting fertilizer use by at least 60%. Overall, this technology offers a sustainable and efficient way to boost agricultural productivity.
