High-yield cultivation and management technology of taro without pollution

The nutritional value of taro is relatively high, and the planting range is relatively wide. It is also called yam, taro, winter yam, etc. This substance can not only enhance the body's immunity, but also prevent some diseases. Taro hair originated in India, and then began to grow in large areas in my country. It can be used not only as a vegetable, but also as a food. Therefore, it is very important to carry out pollution-free and high-yield cultivation management of taro.

High-yield cultivation and management technology of taro without pollution

In order to ensure the yield and quality of taro planting, and to achieve pollution-free planting, strict control is required during the management process, and all links must be ****** and****** level. Increase the yield of taro.

1. The choice of planting land

Taro is a perennial herb. The cultivation of this plant has relatively high requirements for the soil. It likes to grow in loose, fertile and air-permeable soil. Therefore, in order to achieve pollution-free planting and increase yield, it is necessary to pay attention to the thickness, porosity and air permeability of the soil layer in the process of soil selection. Neutral and weakly acidic soils are more suitable for its growth. In the choice of soil, stacking in waste gas, waste, waste water and other areas should be avoided as much as possible in order to reduce the pollution of taro.

2. Soil preparation and fertilization

In the process of taro planting, soil preparation is a more important link. Before sowing taro, the land needs to be leveled. The depth of plowing is about 30 cm. The purpose is to ensure that the taro has a better soil growth environment [2]. In addition, in the process of deep ploughing, some fully decomposed organic fertilizers can be added appropriately, furrow fertilizer and seed fertilizers can be added during the sowing process, and furrow fertilizer can be added appropriately after sowing in some areas to achieve good results. .

3. Selection and planting

Seed selection is a key link and prerequisite for improving the yield and quality of taro. Some problems need to be paid attention to in the process of seed selection. In the process of selecting white taro seeds, it is necessary to pay attention to the size of the seed diameter should be uniform, and there is no disease, insect damage and rot. Planting after seed selection is completed should prohibit continuous cropping, pay attention to rotation with other crops, and at the same time pay attention to the planting distance in the process of planting, and appropriate watering after planting.

4. Weeding and mulching

After the taro is sowed, some weeds will definitely appear in the soil. Therefore, weeds need to be treated in time, and pesticides can be used for spraying, but the dosage must be controlled to avoid affecting the growth of taro. After weeding, it needs to be covered with a film. In order to provide a suitable environment and temperature for the growth of the taro, the surrounding area of ​​the film should be compacted to prevent the wind from blowing up the film and affecting the temperature.

5. Introduce seedlings by breaking membranes, check seedlings and replant

Ten to 15 days after the taro is sown, dental sheaths will appear on the taro. At this time, the taro must be introduced. If the emergence rate can reach 80%, seedlings need to be supplemented in time. This link is the key to increasing the yield of taro.

6. Late field management

Field management is very important to the pollution-free planting of taro. After sowing and introducing seedlings, field management is required. The impact of field management mainly includes the following aspects.

First, fertilization is an important link and must be guaranteed. Taro has relatively high requirements for fertilizers. Nitrogen, phosphorus, and potassium fertilizers are needed during planting. At the same time, topdressing should be done in time, because only when the fertilizer is guaranteed can the yield increase and the accumulation of starch can also be guaranteed.

Second, scientific irrigation must be carried out. This link is effective for a variety of plants. At the same time, this link has strict requirements for taro. Taro prefers a humid environment, but does not like a dry environment. Once its growing environment is dry, it will directly cause the leaves of the taro to turn yellow, and at the same time serious pests and diseases will appear; if the environment where it grows is relatively humid, it will also affect the taro The normal development of the root system. Therefore, during the seedling period, it is necessary to ensure that the planting soil is dry and wet to ensure the healthy growth of taro rhizomes. When taro enters the growing stage, it is necessary to ensure the frequency of watering, that is, watering once every 5 days to ensure the moisture of the soil. If it enters the rainy season, appropriate drainage measures should be taken in time.

Third, the soil cultivation operation is also critical to the growth of taro. Under normal circumstances, the growing taro should be cultivated for about 4 times. Fourth, for the prevention and control of pests and diseases, during the taro planting period, in order to increase yield and achieve pollution-free management, the use of pesticides should be reduced, but certain measures need to be taken to prevent pests and diseases. During this period, the methods that can be used are physical control and biological control. If pesticides must be used, try to use pesticide reagents with lower potency.

Pollution-free cultivation and management of taro has a certain degree of complexity. It not only requires superb planting technology, but also technical management is also very important, especially for the management of each link. Only when all aspects are well done can we achieve the expected high yield. , And achieve pollution-free and economic benefits at the same time.
