In the aftermath of the "512" earthquake, significant damage was inflicted on both the country and its people. To address this crisis, the Ministry of Science and Technology collaborated with experts to produce the *Handbook of Practical Techniques for Earthquake Relief in Rural Areas*, which includes valuable guidance on restoring agricultural production. This article highlights key techniques for growing sprouts and vegetables in disaster-affected regions, aiming to support recovery efforts and ensure food security.
**Pea Sprouts Production Technology**
**(a) Functions and Uses**
Pea sprouts can be grown in just 7 to 10 days, making them an ideal crop for rapid production of fresh vegetables in emergency situations. They help increase market supply and provide essential nutrition during times of scarcity.
**(II) Technical Introduction**
1. **Cultivation Facilities**
- **Protection facilities**: Plastic greenhouses, shade houses, or even simple structures can be used if temperatures remain between 15°C and 30°C.
- **Containers and substrates**: Light plastic trays (62 cm × 24 cm × 4 cm) are commonly used for soilless cultivation. Other materials like tinplate may also be used, though they are heavier.
- **Three-dimensional shelves**: Multi-layered systems allow efficient use of space, with 4–6 layers spaced about 40 cm apart.
- **Additional tools**: Sprayers, watering cans, and basic gardening tools are essential.
2. **Seedling Cultivation**
- **Varieties**: Green peas and hemp peas are best suited for sprout production.
- **Seed preparation**: Soak seeds in water for 18–24 hours after cleaning.
- **Sowing**: Place 0.4–0.5 kg of dry seeds per tray. Germinate at 18–22°C for 2–3 days before moving to the growth area.
- **Growth conditions**: Maintain a temperature of 18–23°C and water 2–3 times daily.
- **Harvesting**: Harvest when sprouts reach about 10 cm in height.

**Radish Sprouts Production Technology**
**(a) Functions and Uses**
Radish sprouts grow quickly, taking only 7–8 days from sowing to harvest, making them an effective way to boost local vegetable supplies.
**(II) Technical Introduction**
1. **Facilities**: Use greenhouses in the south and shade nets in summer. Three-dimensional seedling racks with 4–5 layers are recommended.
2. **Seeds**: Select varieties like Dahongpao Radish and Zhejiang University Changbai Radish.
3. **Sowing and germination**: Soak seeds overnight, then place in trays. Cover with paper to prevent movement during watering.
4. **Environmental control**: Maintain temperatures between 15–20°C and humidity below 70%.
5. **Disease prevention**: Disinfect seedlings with potassium permanganate solution in high-temperature seasons.
6. **Harvesting**: Harvest when leaves are fully developed.
**(III) Technical Sources**
Same as above.

**Summer Green Vegetable Plug Seedling Technology**
**(a) Functions and Uses**
This technique helps rapidly grow leafy vegetables, shortening the nursery cycle and ensuring timely planting in affected areas.
**(II) Technical Introduction**
1. **Site selection**: Choose well-drained, ventilated areas with access to water. Use greenhouses with shade and insect nets.
2. **Plug trays**: Use 200–288-hole trays with a sterile substrate mix (peat: vermiculite = 2:1).
3. **Nursery practices**: Sow seeds after soaking and germination. Water sparingly, and apply foliar fertilizers.
4. **Pest control**: Use insecticides like Kungfu, Bt, and others to manage pests like aphids and caterpillars.

**Chinese Cabbage Rapid Cultivation Technology**
**(a) Functions and Uses**
Chinese cabbage grows quickly, helping to meet fresh vegetable demand in affected areas.
**(II) Technical Introduction**
1. **Variety selection**: Choose fast-growing types such as Shanghai April Slow, Nanjing April White, etc.
2. **Sowing methods**: Direct seeding or transplanting. Apply organic fertilizer before sowing.
3. **Fertilizer and water management**: Apply urea and compound fertilizer before harvest.
4. **Pest control**: Use insecticides like dimethoate or malathion to control aphids.
5. **Harvesting**: Harvest when plants have 4–5 leaves or mature.

**Field Vegetable Management and Post-Disaster Replanting Measures**
**(a) Functions and Uses**
This guide supports field management and replanting in disaster-affected areas, especially in Sichuan, Chongqing, and Gansu.
**(II) Technical Introduction**
1. **Drainage and flood prevention**: Clear ditches and remove standing water.
2. **Replanting**: Grow fast-maturing crops like radishes, cabbages, and spinach.
3. **Fertilization**: Apply urea and compound fertilizers after sunny days.
4. **Protective measures**: Use insect-proof and shade nets to reduce pest and weather damage.
5. **Pest control**: Monitor and treat diseases promptly to prevent outbreaks.
**(III) Technical Sources**

**Vegetable Crop Disaster Prevention and Reduction Measures**
**(a) Functions and Uses**
These measures aim to minimize earthquake-related damage and promote vegetable recovery.
**(II) Technical Introduction**
1. **Damaged fields**: Remove debris and restore damaged plots.
2. **Crop salvage**: Upright fallen plants, wash leaves, and re-root them.
3. **Spraying**: Use foliar nutrients like potassium dihydrogen phosphate to aid recovery.
4. **Pest control**: Focus on preventing wilt and bacterial diseases.
5. **Soil restoration**: For severely damaged areas, replace topsoil and improve drainage.
