Detailed Explanation of Key Technical Points for Taro Field Management
Taro is a very delicious tuber vegetable, and in many other places it is also used as a food crop. Actually, taro has a similar function to potatoes, but its effect is even better than that of potatoes. Taro cultivation is very common, but taro has different growth stages, and these growth stages also determine different management methods. So what the editor wants to talk about today is the field management techniques for taro at different growth stages. Let's take a look below!
1. Seedling stage
If there are no unexpected situations after sowing, the seeds usually germinate and emerge in about one month. At this time, the film must be broken in time to guide the seedlings out of the soil, avoiding burns to the seedlings caused by excessively high temperatures. After the seedlings emerge, press the film opening firmly to improve the soil's water and fertilizer retention capacity and reduce the growth of weeds. During the seedling stage of taro, the demand for water is not high. If the soil moisture content is too high, it can easily cause seedling rot and root waterlogging. According to soil moisture conditions and weather and other factors, appropriately drip irrigate with a small amount of water, ensuring the soil is relatively moist.
2. Tillering stage
The tillering stage is a relatively important stage in the taro growth period, because the tillering stage directly determines the later yield and quality of taro. At this stage, in order to promote taro formation and taro growth, sufficient nitrogen fertilizer should be applied in time as a topdressing. And this stage is the peak period of taro water demand, but when watering, the method of large-volume irrigation cannot be used, to prevent waterlogging in the taro field. After watering, do a good job of loosening the soil and weeding, and strengthen the soil's ventilation and air permeability. When loosening the soil, stand behind the loosened soil position to prevent stepping the soil firm, which would make the soil loosening work ineffective.
3. Taro formation stage
The taro formation stage comes after the tillering stage. This stage is also a very critical time in taro cultivation. The mother taro and daughter taro expand rapidly during this period. To ensure successful expansion, we must provide sufficient nutrients and water, and apply fertilizer at least twice. The taro formation stage of taro is generally in summer. Summer has high temperatures and drought, yet it is also the time when taro grows rapidly, so watering should be done in a timely manner according to weather and soil moisture conditions. The watering interval is about 6 days. Secondly, the daughter leaves of taro consume a lot of nutrients, so we should promptly cut off excess daughter leaves to improve the yield and quality of taro.
4. Dormant stage
After taro passes through the taro formation stage, the growth rate of the tubers slows down, and expansion gradually stops. The aboveground plants also basically stop growing. Taro then roughly enters the dormant stage. The dormant stage arrives in the late growth period of taro. At this stage, taro's demand for water and nutrients gradually decreases. The frequency of watering and fertilizing should begin to be reduced, especially when harvest is approaching, try to keep the soil in a dry state. For plots that need to retain seeds, this is even more important. Keeping the soil dry is beneficial for later planting and can also improve the storage capacity of taro.
The above is a brief introduction to taro field management techniques. What the editor introduced are several relatively critical periods in the taro growth stages. The management work during these periods is very important. Once management is poor, it may cause relatively serious restrictions on taro growth. That is all for today's introduction.
