How to grow taro for high yields? A detailed guide to the latest cultivation techniques
Taro is a vegetable that many people enjoy eating in daily life. Its nutritional value and medicinal value are both relatively high. Besides being eaten, it can also be used to make vinegar, brew wine, extract alkaloids, and so on, giving it good economic benefits. So how should taro be grown to achieve high yields? Follow the editor and take a look.
1. Choosing the site
First, you need to choose a suitable planting site. Many people think that because taro likes water, it can grow in water. This is actually a mistaken idea. Although taro likes water, it cannot stay submerged in water for long periods, and it cannot be planted in continuous cropping. Therefore, when choosing a planting site, be sure to choose a place with good moisture retention, convenient drainage, and where taro has not been planted in the previous crop. After choosing the planting site, deeply plow and turn the soil, and at the same time apply enough base fertilizer, generally mainly organic fertilizer or compound fertilizer.
2. Sowing and raising seedlings
Before sowing, choose suitable varieties to plant according to the local climate conditions. There are many varieties of taro, but they can be roughly divided into water taro and upland taro, so seeds should be selected according to the local environment. Generally, spring is the best time to sow taro, but in some areas where spring temperatures rise slowly, sowing can be appropriately delayed, though it should not be later than Qingming Festival at the latest. When sowing, you can choose to cover with plastic film or not. Compared with other vegetables, taro sowing requires a relatively large amount of seed; generally about 200 kg of seed is needed per mu. When sowing, use the trenching method. The row spacing of each trench is generally about 50 cm, and the distance between each taro cannot be too close, otherwise it is not conducive to the development and growth of the taro.
3. Fertilizer and water management
Taro is tolerant of waterlogging but not drought, so drip irrigation can be used when watering taro. When ground cover and drip irrigation are combined, drip irrigation can dissolve all the fertilizer needed for taro growth and development in water and deliver it precisely to the taro root zone. When choosing fertilizers, nitrogen fertilizer and potassium fertilizer can be selected, because they have a relatively large impact on taro yield and quality. Generally, 90 days after taro emergence, its absorption of nitrogen reaches its peak, and around 110 days after emergence, its absorption of phosphorus and potassium reaches its peak. Therefore, during these two periods, fertilizer should be applied promptly according to its needs to improve yield and quality.
4. Field management
Summer rainfall is relatively abundant, so attention should also be paid to weeding. During management, attention should also be paid to preventing and controlling pests and diseases, and once they are found, they should be controlled promptly. There are many rainstorm weather events in summer, so after rain, check the conditions promptly, and it is best to do drainage and humidity reduction work to avoid outbreaks of disease.
