Sweet potato planting method
1, choose the soil
Sweet potato on the soil requirements are not high, adaptable, choose the deep soil, loose and breathable sandy soil planting can be, before sowing the whole land tilling the soil broken up, fine, deep plowing of 30 cm or so, applying farmyard manure as a base fertilizer, and soil mixing evenly.

Urea irrigation ground, timely replenishment of nutrients, is conducive to improving yield.
4, field management
Sweet potato seedlings grow to 50 cm or so, the need for timely rectification and topping, to remove the tip of the shoots, with sterilized scissors to the growth of more branches and branches, cut short 2-3 branches, so that nutrients back to the main stem to get more nutrients to reduce nutrient consumption.
