Abstract

The invention discloses a method for planting purple sweet potatoes. The method for planting the purple sweet potatoes comprises the following steps of (1) selecting a soil-loose, fertile, high-terrain and sunny land as a planting land of the purple sweet potatoes; (2) selecting purple sweet potato seeds which are medium in size and have no gap and damage, putting the purple sweet potato seeds into a soaking solution for soaking 8 - 10 h, and then burying the seeds in a seedling bed; (3) after seedlings in the seedling bed grows to 15 - 18 days, conducting topdressing, wherein fertilizers usedin the topdressing is 50 kg organic fertilizers per mu; (4) obliquely planting the seedlings in the seedling bed on a deep ploughing land; (5) topdressing seedling-promoting fertilizers on the seedlings after obliquely planting and carrying out seedling control and topping; (6) when sweet potato vines grow to 0.5 m, spraying paclobutrazol in the afternoon; and (7) conducting prevention and control work on cutworm, prodenia litura and black spot. The method for planting the purple sweet potatoes has the advantages of high yield, good purple sweet potato quality and strong ability to adapt to environment, and can effectively improve the germination rates of the purple sweet potatoes.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for planting purple sweet potatoes. Background technique [0002] Purple sweet potato is also called black potato. The potato flesh is purple or deep purple.
