The invention relates to a method for cultivating seedlings of oil peonies, and belongs to the field of agricultural
seedling cultivation. The method comprises the following steps: selecting a nursery; performing weeding in advance; performing deep ploughing and tedding; performing
soil preparation and making furrow ridges; harvesting seeds;
processing the harvested seeds; sorting the processed seeds;
processing the sorted seeds before cultivation;
sowing the processed seeds; managing seedlings; managing nursery stocks. The characteristics of soil are changed by the method of combining farm
manure with a chemical
fertilizer. The seeds for
sowing are harvested at the best harvesting time; the seeds to be cultivated are processed by
gibberellin, ethyl
alcohol,
sodium p(dimethylamino) benzenediazo
sulfonate solution,
carbendazim and
plant ash, and a culture solution is generated during the cultivation of onions, so that the
seed dormancy is broken, the germinating time is advanced, and the
germination rate is increased. Diseases are prevented during cultivation, and different medicaments are sprayed in different seasons so as to prevent diseases, so that the
seedling survival percent is increased. After being cultivated by the method disclosed by the invention, the nursery stocks are thick in plants, the
seedling survival percent is high, the quality is greatly improved, after the nursery stocks are planted, the seed setting rate is high, and the nursery stocks cultivated by the method disclosed by the invention are good varieties for the oil peonies.
