Sweet potato plastic greenhouse nursery - the peak fertilizer industry

In the plastic greenhouse dig 1 meter wide, 20 cm deep ditch to make the nursery plot, excavated soil around the ease discharge into the stems, the number depending on the length of seedling seed furrow may be. After dug in the ditch soil scarification, either a flat, then drained potatoes. When the potato row to row level as well, to ensure that the above line up after tuber formation. After the entire stretch potato row, talk with sand or loam tubers infill slit to secure the tuber. Fill in the gaps potato tubers put on top of a piece of plastic film, will be irrigated on a plastic film, while moving the film side watering, so as not to float tubers. Watering potato surface to 1-2 cm depth so far. When the tubers out of the water, the potato cover with fine soil or sand surface, the thickness of 1-1.5 cm. Mulch is not too thick, or affect the germination rate. After the casing above the tuber, in the furrow do Shed skeleton, covered with plastic film, and dug around the plot with a small ditch, the film can be compacted around. Every day around 9:00, with a thin bamboo strips tapping Shed film, so that dew fall within the film, increase light transmission and temperature in Shed. After the potato seedlings out together, depending on the temperature conditions Shed leaked measures taken and determine if watering in dry conditions according to the plot.
