Land selection and land preparation
Zizania latifolia is suitable for planting in moist plots with loose soil, fertile soil and good drainage. When choosing land, we should avoid low-lying land and saline-alkali land. Before planting, it is necessary to deepen the soil, apply sufficient base fertilizer and open drainage ditches to facilitate water and fertilizer management.
grow seedlings
Seedling raising of Zizania latifolia is generally carried out in early spring. The thick rhizome of Zizania latifolia was cut into 5 ~ 7 cm segments and placed horizontally on the seedbed with the spacing of 15 ~ 20 cm. Then cover the soil for 5 cm and water it. After the seedlings are unearthed, pay attention to shading and sun protection and water and fertilize in time.
transplant
When the seedlings of Zizania latifolia grow to about 15 cm, they can be transplanted. The suitable transplanting time is sunny. Dig planting holes in the field, with the row spacing of 50-60 cm and the plant spacing of 30-40 cm. Plant 1 ~ 2 seedlings in each hole, cover with soil and tamp. Water thoroughly after transplanting.
Tiantuan management
Field management should be strengthened after the survival of Zizania latifolia. Water regularly to keep the soil moist, but don't accumulate water. Fertilization is mainly based on nitrogen fertilizer, supplemented by appropriate amount of phosphorus and potassium fertilizer. In the vigorous growth period of Zizania latifolia, liquid fertilizer can be applied for 2 ~ 3 times.
Water level management
Zizania latifolia likes humid environment, so it needs to keep a certain shallow water level during its growth. After planting seedlings, irrigation is started, and the water depth is kept at 5 ~ 10 cm. With the growth of Zizania latifolia, the water level gradually deepened, and the water depth remained at 15 ~ 20cm before bank closure. Pay attention to uniform water injection when injecting water, so as to avoid water rushing over and pouring water into the water.
Eliminate pests and diseases
The common diseases and pests of Zizania latifolia are Zizania latifolia, Noctuidae, Sclerotinia sclerotiorum and so on. Timely control of pests and diseases can effectively protect the growth of Zizania latifolia. Chilo suppressalis and Chilo suppressalis can be controlled by drugs, while Sclerotinia sclerotiorum needs to strengthen field management, remove the diseased plants in time and burn them.
