A course on the latest field management techniques of taro

Taro is an annual tuber plant, which is generally used as a delicious dish. The nutritional value of taro is no less than that of potatoes, and it is very easy to digest and is not as poisonous as potatoes. But taro can not be eaten raw, must be thoroughly cooked before it can be eaten, otherwise there will be diarrhea, vomiting and other physiological phenomena. What the editor wants to tell you today is the field management technology of taro planting. Let's take a look at it with the editor.

1. Topdressing in time

Taro has a great demand for fertilizer, and topdressing in time is the key measure to ensure the normal development of taro. The development of taro is determined by the nutrient absorption capacity of the root system. The root of taro is called mother taro. In the later stage, the ability of mother taro is getting stronger and stronger, and the demand for nutrition is increasing. At this stage, the nutrition demand of taro is mainly potassium and phosphate fertilizer. When we apply fertilizer, we should pay attention to control the concentration of fertilizer and spray it in a reasonable way, so that the root can not come into direct contact with fertilizer to prevent root burning.

2. Rational watering

During the growth period, taro not only has a great demand for nutrition, but also has a very important water demand. Watering must be done during the planting period, especially in summer, when taro plants grow most vigorously, and the soil should be kept in a moist environment during this period. But the stagnant water should not be too much, because too much will affect the soil permeability and is not conducive to root respiration. Therefore, it is necessary to do a good job of drainage when it is rainy, and to keep water and moisture properly when it is hot and dry to prevent water from evaporating too quickly.

3. Ploughing and weeding

Ploughing and cultivating soil is the most basic work when we grow taro. Every time we fertilize, we have to cultivate soil together with topdressing. Covering soil immediately after fertilization not only improved fertilizer conservation, but also completed the work of ploughing and soil cultivation. The purpose of ploughing and soil cultivation is to improve the air permeability of the regiment and strengthen the nutrient absorption of the roots. Weeding is to remove weeds in the field, because the ability of weeds to compete for nutrition is very strong, so not timely treatment will lead to taro malnutrition, and even make the plant die. Herbicides can be used for weeding, but use as little as possible, because it will also have a certain inhibitory effect on the growth of taro.

4. Other aspects

When the temperature gradually decreases in autumn, the taro will gradually end the expansion period and enter into maturity. There are also some withered and yellow leaves at the bottom of the plant, which can not carry out photosynthesis and hinder the expansion of taro. It is very disadvantageous to its yield and growth, so we should cut off these withered and yellow leaves in time and reduce the incidence of the disease. And we also need to control the number of sub-taro, although sub-taro is the seed of taro, but if there is too much, its nutrient demand will increase, which is extremely disadvantageous to the yield of mother taro.

The above is a brief introduction of taro field management technology, in fact, there are many aspects that we need to pay attention to. For example, timely harvesting, pest control and so on, these are essential work. Timely harvest is beneficial to the quality of taro, if harvested too late, it will increase the probability of rotten fruit, and if it is too early, there will be problems such as unfinished expansion and immaturity.
