Techniques of promoting flowering of Flower Peony in Autumn

Flowers should blossom in early October and should be defoliated in late July. When the leaves were sprayed with 2000ppm ethephon, the leaves changed from green to yellow and fell off gradually. If you can't take off, you can spray it again every 3 days, or you can cut it off directly.

After defoliation of peony plants, dormancy can be released early or later according to the time of flowers.

There are two methods for peony to break dormancy.

1. Flower hormone treatment. The processing time should be determined according to the time spent, and it should be about 50 days in advance. Each flower bud is wrapped in a ball of skimmed cotton the size of soybeans, and then use a brush to drop 500-1OOOppm 920 on the skimmed cotton. Once a day for 3-4 days, the scale buds can sprout and expand. The dryness of the scales is not conducive to the absorption of drugs, so you can peel it off with a knife or remove it and then drop the liquid.

2. Low temperature treatment of peony flowers. This method is 10 days earlier than hormone treatment. Planing out the plant, such as a small number, can be planted in a pot, such as a large amount of wet sand or sawdust and other things, put the plant in the cold storage, so that the branches up, line up, with sand or sawdust to fill the gap below the neck of the root. Row by row, fill in this way, and don't expose the root system to the outside. The temperature in the cold storage was kept at 4 ℃-6 ℃ in the first 7 days and 0 ℃-30C in the latter 7 days. After two weeks, it was taken out and put into the basin. In the early stage, it is best to put it in the shade. After 10 days, the flower buds sprout, and then move to the sun for management.
