The invention discloses a method for protecting seedlings of potatoes planted in winter in the high-temperature
humid climate on the coast of the southern area in China. According to the method, the seedlings of the potatoes planted in winter in the high-temperature
humid climate of the coast of the southern area in China are protected and cultured through
soil preparation and ridging, water drainage
system building, grounded planting,
seedling covering and watering for soil
wetting. In the grounded planting operation process, potato seeds are laid on a
ridge surface of a single
ridge of double rows, seed coat and
bud eyes are downward, a layer of fine soil is scattered on the
ridge surface, and accordingly breathability can be improved due to a flat-laying and thinly-covering mode, the seedlings of the potatoes can quickly come out of the soil and grow quickly under the
photosynthesis, and meanwhile, the seedlings are protected and cultured in a
straw covering mode in the step of
seedling covering, buds of the seedlings of the potatoes are thick and strong, potatoes bodies and roots of the potatoes do not rot, the seedlings grow well, the
survival rate of the seedlings is high, and the method is ingenious, strong in practicability, and very suitable for universally popularized and used.
