Planting techniques of Pinellia ternata

Sunny sandy loam soil with leguminous and gramineous crops was selected, and then deep ploughed to form fields and applied with sufficient base fertilizer. From the last ten days of February to the first ten days of March, a ditch with the depth of 7cm and the width of 15cm is opened according to the distance between rows and plants of 25* 5 cm, then seeds are sown in the ditch, finally soil is covered, a layer of decomposed farm manure and straw is covered, and some clear excrement water is applied. After long emergence, do a good job of water and fertilizer, soil cultivation and other management work can be high yield.

Detailed explanation of dry pinellia cultivation technology:

1. Soil selection

The planting land of dry pinellia ternata will generally be selected at a higher altitude, loose soil, sufficient nutrients, moist, rich in water resources, light is not strong gentle slope or flat, hills. The planting area of dry pinellia needs to be fertilized many times, usually at least once three to four times. Then sprinkle enough farm manure, turn the farm manure into the soil, stir evenly, and then break the soil, leveling can be.

2. Cultivation methods

The planting methods of dry pinellia ternata include bulb propagation and bulblet propagation. Bulb propagation is generally planted around November and December each year, while bulblet propagation is planted in summer and autumn each year. When planting, press the bulbs and bulbils evenly according to the density of 20 cm in row spacing and about 2 cm in plant spacing, finally cover the seeds with soil, then cover a layer of straw or weeds on it, and wait for seedling emergence after watering with water and soil.

3. Daily light

General drought pinellia is afraid of strong light, but this disease does not mean that he does not need light. When planting Pinellia ternata, we should pay attention to daily light management. Generally, sunlight is needed in spring, autumn and winter. The summer light is very strong, then we need to build a shade shed in time, it is best to use translucent, let the sun scatter into the shed, so that the dry pinellia can grow normally.

4. Temperature management

The temperature requirement of dry pinellia ternata for growth is relatively high. The temperature suitable for the growth of Pinellia ternata is between 10 and 15 degrees Celsius. If the temperature is lower than 10 degrees Celsius or higher than 15 degrees Celsius, this pair will affect the normal growth of Pinellia ternata, resulting in poor development of Pinellia ternata. Then we are very important to the temperature management of the field, we generally achieve the purpose of lowering the temperature by watering, especially in summer and winter, we need to pay more attention to the adjustment of temperature. In summer we need to make timely cooling treatment, while in winter we need timely insulation measures.

5. Fertilizer and water demand

Dry Pinellia ternata has a large demand for nutrients, so we need appropriate topdressing in addition to base fertilizer. After the emergence of dry pinellia ternata, we need to irrigate with appropriate amount of feces and urine or appropriate ammonia fertilizer. The second is the corm growth of dry pinellia ternata in the later stage. We need to use potassium fertilizer and phosphorus fertilizer scientifically, so that the corm growth can be strengthened. At the same time, it is necessary to spray appropriate foliar fertilizer to avoid aging of plants. The growth characteristics of dry pinellia ternata are wet, so attention should be paid to the management of field moisture when planting. When the soil in the field is relatively dry, it is necessary to water it in time, but when the water in the field is too much, it is still necessary to discharge the water in time, otherwise the dry pinellia will drown.

The above is the introduction of dry pinellia cultivation technology, I hope to help everyone.
