Fast peony breeding improving technology

Abstract

The present invention performs ground peony breed improvement through high branch grafting process using the plant of white Fengdan peony or other common peony as stock and other peony branch with flower bud as scion, and it uses the improved peony as direct improved plant. The said technology can shorten the culture period of improved peony breed from conventional 5-7 years to about 70 days, raise survival rate of grafted peony plant and reduce cost of grafted peony, and the said technology makes it possible to culture peony plant with several flower colors.

Description

Technical field: [0001] The invention relates to a method for grafting and promoting flowers, especially a rapid replanting and promoting method for peonies. Background technique: [0002] Peony is a famous and precious flower in my country, and is known as the king of flowers. In history, since Sui Tang, it has become the national flower several times. According to research, the history of peony cultivation in my country has been two thousand years. But so far, the traditional methods of peony grafting and promoting (that is, flower urging) in my country have been carried out separately and independently. Peony grafting, as a method of propagation and cultivation, usually relies on ramets firstly, and secondly by selecting peony roots or peony roots as rootstocks, grafting peony soil buds or using new branches of peony varieties as scions, and relying on underground propagation. In the last ten days of the month (summer) to the first ten days of October (cold dew), use s...

AI Technical Summary

Problems solved by technology

This grafting method makes the contact area formed by the scion cambium and rootstock small, less healing points, low survival rate, relying on underground propagation, slow seedling formation, and long cycle

[0003] Generally speaking, the traditional peony grafting and promoting methods have the following main disadvantages: one is discontinuous, and the breeding cycle is long

Peonies grafted with peony roots or peony roots as rootstocks need to grow for 5 to 7 years before they can become flower-promoting plants; the second is that each plant is of the same color, and its ornamental value is relatively low;

The cycle of cultivating perennial peony plants is long and the cost is high. Moreover, no matter whether it is outdoor cultivation in the south or greenhouse cultivation in the north, the perennial species peony that has been strictly selected is used as the promotion plant. The selection, seedling, packaging, The transportation and management requirements are high, resulting in high cost and low productivity, which is unfavorable for the popularization of peony flowers; the fourth is that the survival rate of peonies using the cleaving method is low (generally only 10-20%), even if they survive, they are also easy to age, and the life span is not long. long

[0004] The purpose of the present invention is to overcome the defects of the traditional peony grafting and promoting methods, provide a new method for quickly replanting peony, solve the problems of long breeding cycle, high cost, single flower color, low grafting survival rate and easy aging of peony, and improve the quality of peony. The scientific and technological level and productivity of planting and breeding can better meet people's needs for ornamental flowers
