Taro is generally sown in spring and harvested in autumn. It will be planted from January to March, grow up from August to October, and be harvested.

II. Planting conditions

1. Soil

Taro is a fertilizer-loving crop. It is necessary to choose loam or clay loam with deep soil layer and rich organic matter in order to ensure that the underground corms can absorb rich nutrients, and the pH value of 5.5 is the most suitable.

2. Temperature

Taro is native to India and likes high temperatures. During the growth process, the temperature was kept at 20-30 ℃.

3. Moisture

No matter which variety likes to get wet. Dry taro requires moist soil, while water taro requires a certain water layer.

4. Lighting

No need for strong light, weak light is fine.

3. Planting methods

1. Planting site preparation

The soil for planting taro is rich in fertility, rich in nutrition and thick in soil layer. After choosing the address, the land will be ploughed and trenched, with a width of 50 cm, a depth of 35 cm and a row spacing of about 80-100 cm. Fill the ditch with fertilizer after digging.

2. Sowing seeds

Before sowing, the intact taro should be spread out for a few days, and then placed indoors covered with wet sand for sprouting. The room temperature is kept at 20-25 ℃. It will sprout in about 20 days, and the taro can be planted after sprouting. 4500-6000 plants per mu. The large and small row cultivation method was used to sow seeds according to the plant spacing of 27-33 cm, large row spacing of 60 cm and small row spacing of 30 cm.

3. Watering

Taro is not watered before emergence, keep the soil moist in the middle and later stage, and pay attention to drainage in the rainy season. 80 days after emergence, combined with watering, make a hole beside the plant to apply fertilizer. Taro avoid dry soil, yellow leaves, withered leaves in case of drought, but the soil is too wet and stagnant water is also detrimental to root growth. Make the soil moisture sufficient at the seedling stage, and avoid watering it. In the seedling stage, the soil is dry and wet, and drainage should be paid attention to in case of rain.

4. Cultivate the soil by ploughing.

Taro seedling stage combined with topdressing should carry out mid-ploughing to kill the grass and warm ground, ploughing and leveling the cultivation ditch at the end of the seedlings, and then cultivate the soil once in 20 days, 7 cm thick, twice in total. The purpose of soil cultivation is to inhibit the terminal bud germination and growth of son taro and sun taro, reduce nutrient consumption, make taro fully expand and produce a large number of adventitious roots, and increase the drought resistance of the plant.

5. Harvest

Taro should be harvested in time after it matures. Early-sowing varieties in the Yangtze River basin are mostly harvested from early September to early October, late-sowing varieties are harvested from late September to late October, and mid-late varieties are mostly harvested from the end of September to early November. Due to the needs of the market, harvesting can be appropriately advanced or delayed, but it should generally be finished before heavy frost to prevent taro from freezing damage.

6. Keep the seed

Taro was selected to grow neatly and consistently in high-yielding land, and the plants with the characteristics of the variety were selected as seed plants. The remaining corms should be withered and yellow in the aboveground, and taro should be harvested in sunny days when taro was fully grown. Belong to the multi-seed taro category to 25-50 grams, small should be more than 15 grams, belong to the type of taro should be more than 25 grams.

IV. matters needing attention

Taro in the whole planting process should pay attention to the control of temperature and moisture, do not over-waterlogging, drought, the temperature can not be too low.

Diseases and insect pests that focus on prevention. During the whole growth process, taro may be eroded by fungal and bacterial diseases, such as taro blight, soft rot, etc., should be prevented and treated in time, and the management of water and fertilizer should be strengthened. For aphids, Spodoptera litura, underground pests and other pests need to prescribe the right medicine.

In fact, the cultivation of taro is not difficult, the focus is on the careful management of its growth process. To maximize economic benefits, it is necessary to maintain the whole ecological environment of taro growth.
