High-yield cultivation management technology of taro without pollution

Taro has high nutritional value and a wide range of cultivation. It is also known as yam, taro, winter taro, 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 be planted in large areas in China. It can be used not only as a vegetable, but also as a food. Therefore, it is very important to carry out pollution-free high-yield cultivation management of taro.

In order to ensure the yield and quality of taro planting, and at the same time to achieve pollution-free planting, strict control is required in the management process, and all links in it must be the best to maximize taro yield.

1. The choice of planting land

Taro is a perennial herbaceous plant. The cultivation of this plant has relatively high requirements for soil. It likes to grow in loose, fertile and breathable soil. Therefore, in order to achieve pollution-free planting and increase in yield, the thickness, looseness and permeability of the soil layer need to be paid attention to in the process of soil selection. Neutral and weakly acidic soils are more suitable for their growth, and they should be avoided in the selection of soil in waste gas, waste, wastewater, etc. in order to reduce the pollution of taro.

2. Fertilize the site

In the process of taro planting, land preparation is an important part. Before taro seeding, the land needs to be leveled, and the depth of tillage is about 30 cm. Its 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, and furrow and seed fertilizers are added during the sowing process. After sowing in some areas, the furrow fertilizer can be added appropriately 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 issues need to be paid attention to in the process of seed selection. In the process of selection of white taro seeds, it is necessary to pay attention to that the diameter of the seeds should be uniform, and there is no disease and rot. After the seed selection is completed, continuous cropping should be prohibited, and attention should be paid to rotating with other crops. At the same time, the planting distance should be emphasized during the planting process, and proper watering should be carried out after planting.

4. Weeding film

After the taro is planted, some weeds will definitely appear in the soil, so weeds need to be treated in time, and pesticides can be sprayed, but the amount of medicine must be controlled to avoid affecting the growth of taro. After weeding, mulching is also required. In order to provide a suitable environment and temperature for the growth of taro, the mulch should be compacted around to avoid the wind blowing the mulch and affecting the temperature.

5. Introduce seedlings by breaking the membrane, check seedlings and replant

Ten to 15 days after the taro is sown, the tooth sheath will appear in the taro. At this time, the taro needs to be treated for seedling introduction. If the emergence rate can reach 80%, the seedlings need to be replenished in time, which is the key to increase the yield of taro.

6. Later field management

Field management is very important for the harmless cultivation of taro. After sowing and seedling introduction, field management is needed. The impact of field management mainly includes the following aspects.

First, fertilization is an important part and must be guaranteed. Taro has relatively high requirements for fertilizers. During the planting period, nitrogen, phosphorus, and potassium fertilizers should be used. At the same time, fertilizers should be topped up in time. Because only fertilizers are guaranteed, the output can be increased and starch accumulation can also be guaranteed.

Second, it must be scientifically irrigated, which is effective for a variety of plants, and at the same time it has strict requirements for taro. Taro prefers humid environment and does not like arid environment. Once the growth environment is dry, it will directly cause the leaves of taro to turn yellow, and serious pests and diseases may also occur; if the growth environment is relatively humid, it will also affect taro The normal development of the root system. Therefore, during the seedling period, it should be ensured that the planting soil is dry and wet, and the healthy growth of the taro roots is guaranteed. When the taro enters the stage of growing trees, the number of watering needs to be guaranteed, that is, watering once every 5 days, the purpose is to ensure the soil is moist. If entering the rainy season, the corresponding drainage measures need to be done in time.

Third, carry out the earth-cultivation operation, which is also very important for the growth of taro. Under normal circumstances, the cultivation of the taro should be carried out about 4 times. Fourth, in the prevention and control of diseases and insect pests, during the taro planting period, in order to increase production and achieve pollution-free management, the use of pesticides should be reduced, but certain measures need to be taken to prevent and control pests and diseases. The means that can be used during this period are physical control and biological control. If pesticides must be used, try to use pesticides with relatively low medicinal properties.

The management of pollution-free cultivation of taro has certain complexity, not only requires superb planting technology, but also technical management is very important, especially for the management of all links, only when all aspects are done well, can we achieve the expected high yield , While achieving pollution-free and economic benefits.
