The new sweet potato line “85-2399” has the advantages of high yield, high quality, disease resistance and storability. Nearly 20,000 mu have been planted in our province. At present, the planting area is still expanding. The purpose of this experiment is to determine the strain Suitable range of planting period, to provide the basis for further expansion of promotion. First, the basic situation of the experiment set four planting period, followed by May 25, June 10, June 25 and July 10, to meet the province’s largest sweet potato cultivation area of continuous cropping needs . Randomized block arrangement, repeated four times, the plot area of 3 centimeters, the density of 4000 plants per acre. Breeding hot film insulation incubation, March 13 under the planted. Field Fertility in the finest, not fertilized during childbirth, drought, pest control.
