A Detailed Guide to Dryland Pinellia Planting Techniques and Field Management Methods
For seed-piece selection, choose a sunny sandy loam whose previous crop was a legume or grass-family crop, then deep-plow it to make field beds and apply plenty of base fertilizer. In late February to early March, open a furrow 7cm deep and 15cm wide at a row-to-plant spacing of 25*5cm, then sow the seeds into it and finally cover with soil, spread a layer of rotted farmyard manure and rice straw, and apply some clear manure water. Once seedlings emerge, good management of water, fertilizer and earthing up will give a high yield.
A detailed guide to dryland Pinellia planting techniques:
1. Soil selection
Dryland Pinellia is generally planted on gentle slopes, flat land or hills at relatively high altitude, with loose soil, abundant nutrients, moisture and water resources, and not-too-strong light. The planting site for dryland Pinellia needs to be fertilized and turned over several times, generally at least three to four times a year. Then spread plenty of farmyard manure, turn the farmyard manure into the soil and mix it evenly, then break up the clods and level the ground.
2. Planting methods
The planting methods for dryland Pinellia are corm propagation and bulbil propagation. Corm propagation is generally carried out around November or December each year, while bulbil propagation is carried out in the summer and autumn each year. When planting, place the corms and bulbils evenly at a density of about 20cm between rows and 2cm between plants, then cover with soil to bury them, spread a layer of rice straw or weeds on top, and water thoroughly with water and soil, then wait for seedlings to emerge.
3. Daily light
Generally, dryland Pinellia is afraid of strong light, but this does not mean it does not need light. When growing Pinellia, we must pay attention to daily light management; in general, sunlight is still needed in spring, autumn and winter. Summer light is very strong, so we need to build shade sheds in good time, preferably semi-transparent ones, so that sunlight scatters into the shed and dryland Pinellia can grow normally.
4. Temperature management
Dryland Pinellia has relatively high temperature requirements for growth. The temperature suitable for dryland Pinellia growth is between 10 and 15 degrees; if the temperature is below 10 degrees or above 15 degrees, this will affect the normal growth of dryland Pinellia, leading to poor development. So field temperature management is very important for us; we generally achieve the purpose of lowering the temperature by watering, and especially in summer and winter we need to pay more attention to temperature regulation. In summer we need to carry out cooling treatment in good time, while in winter we need to take insulation measures in good time.
5. Fertilizer and water requirements
Dryland Pinellia has a relatively large demand for nutrients, so in addition to the base fertilizer, we also need to topdress appropriately. After dryland Pinellia emerges, we need to irrigate with an appropriate amount of manure and urine water or a suitable nitrogen fertilizer. Next is the later corm growth of dryland Pinellia; we need to use potassium fertilizer and phosphate fertilizer scientifically, which can make the corms grow larger. At the same time, foliar fertilizer also needs to be sprayed in an appropriate amount to prevent the plants from aging. The growth characteristic of dryland Pinellia is that it likes moisture, so when planting, special attention must be paid to field water management. When the field soil is relatively dry, water in good time, but when there is too much water in the field, drain the water in good time, otherwise dryland Pinellia will also drown.
The above is the relevant introduction to dryland Pinellia planting techniques. We hope it is helpful to everyone.
