The northern region is suitable for spring sowing and the southern region is suitable for autumn sowing. Like warm and humid climate, the suitable growth temperature is 15~25℃, and it grows faster under the conditions of high soil temperature and air temperature.
The origin of cowhide
In the 5th century, cowhide was introduced into China from Arabia, mainly distributed in southern Europe, and now it is also introduced and cultivated in the Yangtze River basin and its southern area.
Method for plan cowhide
1. Soil preparation: Before planting cowhide vegetables, clean up the sundries on the soil, then turn over the soil, bask in the sun for two days, and then break the clods to prepare for sowing.
2, seed treatment: sweet potato seeds have a shell, which is hard. Seeds need to be soaked in water before sowing, which can shorten the emergence time and make the emergence more orderly.
3. Seeding and seedling raising: Cowhide needs more nitrogen fertilizer and less phosphorus and potassium fertilizer. Planting with farmyard manure can meet its growth needs. Sprinkle cowhide seeds evenly and cover the soil layer the thickness of your index finger.
Key points of cowhide planting management
Water cowhide vegetables in time during the growth period, pay attention to drainage in rainy summer to prevent waterlogging, weed in time, and often loosen the soil and peel leaves, but don't leave residual petioles when peeling leaves.
