Selecting and preparing the land
Wild rice is suitable for planting in loose soil, fertile, well-drained moist plots. Low-lying land and saline land should be avoided when selecting land. Before planting, the soil should be deep ploughed, apply enough fertilizer, and open a good drainage ditch for water and fertilizer management.
Seedling
Wild rice seedlings are generally carried out in early spring. The robust wild rice rhizome is intercepted into a short section of 5 to 7 centimeters, placed horizontally on the seedbed, maintaining a spacing of 15 to 20 centimeters. Subsequently mulch the soil for 5 cm and water thoroughly. When the seedlings emerge from the soil, pay attention to shade and sun protection, and timely watering and fertilization.
Transplanting
When the wild rice seedlings grow to about 15 centimeters, they can be transplanted. Transplanting time to sunny days is preferred. In the field dug a good row spacing of 50 to 60 cm, planting holes 30 to 40 cm apart. Plant 1 to 2 seedlings in each hole, and cover with soil compaction. Water thoroughly after transplanting.
Field management
After the wild rice planting has survived, field management should be strengthened. Regular watering, keep the soil moist, but not waterlogged. Fertilizer to nitrogen-based fertilizer, moderate supplemental phosphorus and potassium fertilizer. In the wild rice exuberant growth period, you can chase the application of 2 to 3 times liquid fertilizer.
Water level management
Wild rice prefers a moist environment, and needs to maintain a certain shallow water level during the growth process. After planting seedlings that is the beginning of irrigation, the water depth is maintained at 5 to 10 centimeters. With the growth of wild rice, gradually deepen the water level, to seal the line to maintain 15 to 20 centimeters of water depth. Pay attention to the uniformity of the water injection, to avoid the water flow is too fast rush down wild rice.
Pest control
The common pests and diseases of wild rice are wild rice borer, wild rice moth, botrytis and so on. Timely control of pests and diseases can effectively protect the growth of wild rice. The wild rice borer and wild rice night moth can be prevented and controlled by drugs, mycosis need to strengthen field management, timely removal of diseased plants and burned and destroyed.
Harvesting
Wild rice is generally mature in the fall. When the base of the stem of wild rice expanded, spherical or oval can be harvested. Harvesting can be cut off from the base of wild rice with a sickle or knife, and avoid damage to the root system. After harvesting, wild rice should be promptly placed in cold water to preserve the fresh taste.
