A kind of rose seed breeding method

Abstract

The invention relates to a method for raising rose seedlings. The seedling machine is used to separate the pulp and seeds of the rose hips, and the pulp and the seeds are washed separately. The pulp is washed, dried and sterilized to make rose hip tea; Place in the environment with a temperature of 15-26 degrees and an air humidity of 30%-60% to dry in the shade for 1-5 days, then mix the seeds and cytokinins evenly and put them in a ziplock bag and store at room temperature, every 15 Open the ziplock bag for 4-8 minutes every day to ensure enough air; at the same time, add 9-13ml of sterile water to ensure that the seeds are moist; take out the rose seeds that have been placed for 12-21 weeks, and soak them with a germination agent for 2-6 hours; The seeds are separated from the sprouting agent, sown, and transplanted after the seedlings are produced; the rose seed breeding method adopted in the present invention is not only simple to operate, but also has a high germination rate, and at the same time, the survival rate of the rose seedlings is high, which is suitable for large-scale production. , and the production cost is low, which meets the requirements of environmental protection.

Description

technical field [0001] The invention relates to the technical field of rose planting, in particular to a method for raising rose seedlings. Background technique [0002] Rose is a general term for some plants of the genus Rosa, mainly referring to the varieties and horticultural varieties of rose vines. The fruit is spherical, cold-resistant, and there are wild and many horticultural varieties, which can be propagated by layering or grafting. Rose can be used medicinally, and the rose porridge made from it has good nutritional value. Mainly distributed in temperate, subtropical and tropical mountainous regions of the northern hemisphere. [0003] In the prior art, the method of cutting is usually adopted to raise seedlings, but the method of raising seedlings of this vegetative propagation also receives the restriction of cuttings or grafting materials, and the survival rate of some varieties such as Sichuan and Yunnan roses is very low after the cuttings. Therefore, rose s...

Problems solved by technology

[0003] In the prior art, cuttings are usually used to grow seedlings, but this method of asexual reproduction is also limited by cuttings or grafting materials, and some varieties such as Sichuan and Yunnan roses have a very low survival rate after cuttings. Therefore, rose seedlings are important for The cultivation of new varieties and the large-scale production of roses are all necessary

[0004] But the air permeability of the seed coat of rose seeds is poor, and it has a deep dormancy period, and the germination rate is low; in the traditional technology, the seeds are soaked in an acid-base solution to change the air permeability of the seed coat, and then the seeds are treated by low temperature stratification. Although this can improve the germination rate of seeds, the quality of the seedlings cultivated is poor, and the survival rate after transplantation is low; and the acid-base waste liquid is difficult to handle, which is easy to cause environmental pollution; at the same time, the low-temperature stratification method has higher requirements on temperature, and It takes a long time and needs to purchase low-temperature equipment, which not only increases production costs, but also increases energy consumption
