The invention belongs to the crops plantation technical field, and specifically discloses a sweet potato plantation method comprising the following steps: 1, soil working: deep ploughing and applying a base
fertilizer; 2, ridging: forming a trench on the
ridge top; 3,
seedling growing and selecting; 4, planting; 5, applying fertilizers; 6,
disease control. The base
fertilizer is formed by
potassium metasilicate, domestic
fungus bacterium
slag, rice
bran, modification
vermiculite powder and microbe bacterium
manure according to certain weight parts; a foliar
fertilizer is formed by
caproic acid diethylaminoethanol ester,
methylene succinic acid, animal
amino acid and a
trace element fertilizer according to certain weight parts. The method starts from fertilization management, the base fertilizer and the foliar fertilizer are matched in usage, thus allowing fertilizer
nutrient release time and intensity to match with the crops
nutrient absorption rules, improving the base fertilizer and foliar fertilizer
utilization rate, and further improving the sweet potato yield; in addition, the base fertilizer also contains soil purifying ingredients, thus improving the potato
quality safety.
