The bamboo grasshopper, also known as the "fungus queen," is a rare and highly valued edible mushroom. China began artificial cultivation of this unique fungus in the 1970s, initially thriving in the mountainous regions of Jiangnan. By the late 1980s, researchers successfully used crop stalks to grow bamboo grasshoppers, expanding cultivation to the northern plains. Since 2000, an efficient intercropping system has been developed, combining bamboo vines with grain crops, significantly boosting economic returns.
**Cultivation Patterns and Expected Yields**
Table 1 outlines different cultivation methods and their expected outputs:
| Crop Name | Cultivation Season | Area (m²) | Yield (kg) | Output Value (¥) |
|------------------|---------------------------------|-----------|------------|------------------|
| Wheat | Mid-October to end of May | 330 | 300 | 400–450 |
| Lettuce | Early November to late March | 330 | 2000 | 1000–1500 |
| Bamboo Shoots | End of March to end of September| 165 | 25–30 | 2000–2500 |
| Corn | Mid-April to mid-July | 330 | 300–400 | 350–500 |
| Luffa Gourd | Mid-May to late September | 330 | 2000–2500 | 1200–2000 |
| Cabbage | Late July to early October | 330 | 3000 | 1200–1800 |
**Key Cultivation Techniques**
**Autumn Sowing of Wheat:**
Choose flat, sunny, well-drained land with slightly acidic soil. In mid-October, sow six rows of wheat spaced 1 meter apart along the north-south direction.
**Winter Planting of Lettuce:**
In early November, dig 15 cm deep ditches between the wheat rows, 15–20 cm wide. Shape into a turtle-like mound, plant two lettuce plants per side, spaced 25 cm apart. Cover with plastic film, and use a small arch shed in February for protection. Harvest by late March.
**Spring Planting of Bamboo Shoots:**
After harvesting lettuce, prepare the area by digging 50 cm wide and 10 cm deep trenches. Add lime, sterilize, and layer with soybean stalks, corn stalks, and bacterial cultures. Top with soil, cover with plastic, and ventilate daily. Once temperatures rise above 25°C, remove the film and add straw for moisture retention.
**On-Demand Corn Cultivation:**
Plant corn in mid-April, 5–10 cm away from the bamboo clumps. The tall corn provides a moist environment for bamboo growth, and its stalks later serve as luffa supports.
**Luffa Gourd Cultivation:**
Plant luffas in mid-May, 50 cm apart from corn rows. Use bamboo poles or concrete posts with wires at 2 meters high to support climbing. Luffas provide shade and moisture for bamboo growth.
**Summer Cabbage and Wheat Management:**
After harvesting summer cabbage and wheat, leave space for pathways. Plant early autumn cabbage in mid-July, harvest before National Day. After the second bamboo harvest, cut luffas and corn stalks, and use them as fertilizer.
**Important Precautions**
**Choosing Varieties:**
Use high-quality, climate-adapted strains. For bamboo, select medium-to-high temperature varieties like DL-01, which thrive at 25–35°C.
**Selecting Cultivation Materials:**
Use fresh, dried crop stalks, cut into 5–10 cm pieces. Soak them until moisture reaches 65%. For 1 m², 10 kg of dry material is needed.
**Soil Covering Material:**
Use humus-rich garden soil, crushed into bean-sized particles and sun-dried for sterilization. Maintain 65% moisture when used.
By integrating bamboo shoots with grain and vegetable crops, farmers can maximize land use, reduce waste, and increase income. Compared to traditional crops like wheat and corn, this system offers double income, making it a sustainable and profitable farming method for many rural families.
