Where is the cold potato produced 1, production area
Cold potato originated in tropical America, and now it is cultivated all over the world. In China, it is mainly distributed in Sichuan, Chongqing, Fujian, Hunan, Taiwan Province, Guangdong and other places, and it is also called bean potato, which is a leguminous herb with edible fleshy roots, but its seeds are highly toxic and inedible.
2. Soil conditions
Cold potato is suitable to grow in loose and fertile places with good drainage. When cultivating cold potato, it is necessary to apply farm manure or rapeseed cake fertilizer to the soil one month before planting. The soil can be ploughed by machine to make the fertilizer decompose quickly, enhance the fertility of the soil and provide nutrients needed for germination of cold potato.
3. Planting method
When planting cold potato, it is necessary to soak its seeds in warm water for 6-8 hours, so that the cold potato seeds can absorb enough water, and then put the seeds in an environment with a temperature of about 27 degrees to accelerate germination. After the cold potato seeds are exposed, they can be sown on the soil surface and covered with thin soil to make the cold potato grow healthily.
4. Maintenance management
When maintaining the cold potato, it is necessary to build a bracket on the soil surface when the plant grows vines, and then pull the vines of the cold potato onto the bracket and fix them tightly with nylon thread to prevent the cold potato from being blown by strong wind. Then, potassium sulfate fertilizer should be applied to the cold potato once to promote the rapid flowering and fruiting of the plant.
