How to cultivate taro for high yield

Taro should be very familiar to everyone and should be eaten frequently in life, but people who often cook will find that their hands itch every time they wash taro. It is said that this is a phenomenon of allergy to taro. Although many people are unwilling to wash taro, they still can't resist the desire to eat taro.

What is taro?

Taro, also known as taro, taro, the underground bulb of Araceae plants, the shape and meat quality vary from variety to variety, usually eaten as small taro. Perennial tuber often cultivated as an annual crop. The leaf is shield-shaped, the petiole is long and hypertrophic, green or purplish red; the base of the plant forms a short shrinking stem and gradually accumulates nutrients to form a fleshy bulb, called "taro" or "mother taro", spherical, ovoid, oval or massive, and so on. The mother taro has a brain bud in each node, but the axillary buds in the middle and lower nodes are the strongest, and the first tiller occurs to form a small corm called "son taro". Under suitable conditions, great-grandson or great-grandson taro can be formed.

Morphological characteristics of Taro

Taro, a perennial tuber, is often cultivated as an annual crop. The leaf is shield-shaped, the petiole is long and hypertrophic, green or purplish red; the base of the plant forms a short shrinking stem and gradually accumulates nutrients to form a fleshy bulb, called "taro" or "mother taro", spherical, ovoid, oval or massive, and so on. The mother taro has a brain bud in each node, but the axillary buds in the middle and lower nodes are the strongest, and the first tiller occurs to form a small corm called "son taro". Under suitable conditions, great-grandson or great-grandson taro can be formed. Sex likes high temperature and humidity, is not tolerant to drought, is more tolerant to shade, and has the characteristics of aquatic plants, which can be cultivated in paddy field or dry land. The absorptive capacity of root system is weak, sufficient water is required in the whole growing period, and the clayey soil with rich, deep and strong water retention is suitable for wide adaptability to soil. the seed taro begins to germinate at 13: 15 ℃, the optimum temperature for growth is more than 20 ℃, the corm is formed under the condition of short day, and the optimum temperature for development is 27: 30 ℃. In case of low temperature and drought, the growth is poor, which seriously affects the yield.

How to grow taro to achieve high yield

1. Select a parcel

Taro land should choose black soil and alluvial soil with deep soil layer, fertile soil, high content of organic matter, convenient drainage and irrigation, good performance of water and fertilizer conservation, and slightly higher water content.

2. Soil preparation and fertilization

Remove stubble, turn 30 cm deep and ridge 70 cm wide, applying 75 cubic meters of agricultural fertilizer per hectare, 200 kg of chemical fertilizer, 00 kg of phosphorus and 150 kg of potassium as base fertilizer.

3. Budding and planting

In order to prolong the growth period of taro, the taro should be treated with hot Kang or plastic arch shed 20 days before sowing. When the taro bud grows to 5cm, you can get off the Kang (bed) and sow seeds after cutting. The depth of sowing is 4mi 5cm, and the distance between plants is 35cm. When covering the soil, the seed buds should be slightly exposed.

4. Field management

① topdressing. Taro is a fertilizer-loving crop with a long growth period, so the combined application of nitrogen, phosphorus and potassium should promote topdressing by stages, and the frequency of topdressing should be determined according to the growth of taro.

② watering. Taro is a water-loving crop. During the period from emergence to harvest, the soil must be kept moist, and the water content of the soil should be slightly higher than that of the general dry land. It should be irrigated in time in case of drought and drained in time when stagnant water is encountered.

③ ploughing and cultivating soil. Weeding in time at seedling stage, loosening soil, raising soil temperature and promoting growth. When the seedling stage ends, the soil is cultivated every 10 days or so, the main purpose is to restrain the germination of son and sun bud and promote the growth of underground taro, which is the key measure of taro cultivation. Only by pressing the buds of offspring can the yield and quality be improved.

Prevention and cure of ④ disease. To give priority to agricultural control and prevention, crop rotation can be used to eliminate inferior taro species and choose disease-free taro species. Reduce the occurrence of diseases. Chemical control can choose a variety of fungicides, in different, the same growth period for foliar spray, in order to prevent soft rot, blight and so on.

5. Harvest

In order to meet the needs of the growth period to the maximum extent, the yield and quality can be improved by harvesting as late as possible on the premise of not suffering frost damage.

Planting conditions of Taro

1. Temperature: Taro needs high temperature and humid environmental conditions, and the large temperature difference between day and night is beneficial to the formation of corm, and it is the most suitable for corm formation at 28: 30 ℃ in daytime and 18: 20 ℃ at night.

2. Moisture: both water taro and dry taro like the humid natural environment, the dry taro growth period requires soil moisture, and the water taro growth period requires a certain water layer.

3. Light: Taro is resistant to weak light, the requirement of light intensity is not very strict, it grows well under scattered light, and short-day conditions are required for the formation and expansion of corms.

4. Soil: water taro should be cultivated in paddy field, low-lying land or ditch. Although dry taro can grow in dry land, it still maintains the ecotype of marsh plants and should be planted in humid areas.

In fact, the cultivation of taro is relatively simple. Taro likes to live in a hot and humid environment. The demand for sunlight is not very high, so growers only need to make sure that they have enough water, but in order to get high-yielding taro, just water is definitely not enough.
