Problems solved by technology

During the cultivation process, it was found that the pollen germination rate of Lonicera plants varies greatly, and the seed setting rate also varies greatly. Some species have extremely low or no seed setting rate, and self-pollination and cross-pollination are difficult to fertilize and bear fruit; on the other hand, Lonicera perforatum The emergence rate of natural sowing is very low, only about 10%. After sowing in autumn or spring, some seeds will emerge in spring, and even some seeds will not emerge until autumn of the current year. The emergence time is long and difficult to manage, which also brings difficulties for variety selection. Improving the germination rate of Lonicera perforatum seeds is a necessary condition to solve this problem
[0006] Known by above-mentioned prior art, the research about honeysuckle seed seedling raising technique is less, only relates to how to improve the germination rate (germination rate) of seed, and technology is single
Patent CN102612889B discloses a method for improving the survival rate of Lonicera persicae seed seedlings, but the pretreatment before sowing in this method includes multiple steps such as stratification treatment, sterilization, seed soaking with growth regulator, and light. The process is cumbersome and difficult to operate. And need to process Lonicera persicae seeds with pesticide (70% carbendazim wettable powder), although carbendazim is a low-toxic pesticide, it is also unfavorable for the health of nursery personnel, and the environmental protection is relatively poor

Embodiment 1

[0025] Embodiment 1, the impact test of different treatment modes on the emergence rate of Lonicera perforatum seeds

[0026] Comparing the effects of low temperature storage, direct seeding, outdoor stratification treatment of seed vermiculite embedding and indoor room temperature storage on the emergence rate of Lonicera persicae seeds, this experiment took the emergence rate and emergence time as the evaluation indicators to evaluate the effect of breaking the dormancy of Lonicera persicae seeds. Effect.

[0027] Low-temperature storage treatment is to put the seeds into paper bags and place them in a freezer or household refrigerator for refrigeration. The processing temperature of the freezer or household refrigerator is about 5°C. Seed direct seeding treatment refers to soaking the seeds for 12 hours and sowing them in 72-hole seedling trays, sowing 1 seed per hole, and the sowing substrate is seedling soil purchased in the market. The outdoor layering treatment of seed...

Embodiment 2

[0032] Embodiment 2, the optimization selection test of germination temperature

[0033] Lonicera persicae seeds stored at a low temperature of 5°C were cultured in a petri dish to germinate, and the temperature range of the incubator was set at 12°C to 28°C, and the germination rate was used as an evaluation index.

[0034] Lay two layers of filter paper in a petri dish, spray the filter paper with clean water, evenly place 30 Lonicera persicae seeds on the filter paper in each petri dish, cover the seeds with two layers of filter paper, and place the petri dish in an incubator to accelerate germination , Spray above the seeds with a watering can every 2 to 3 days, so that the filter paper is always kept moist. The germination temperature of the incubator was set at 12°C, 15°C, 18°C, 20°C, 23°C, 28°C and 16-27°C, respectively. The cultivation time began on March 21, 2015, and the statistical deadline was 2015. On May 21, count the germination rate in 60 days under the above-...

Embodiment 3

[0043] A preferred method for cultivating seedlings using Lonicera perforatum seeds, specifically comprises the following steps:

[0044] 1) Harvesting fruit: the maturity period of Lonicera persicae seeds is inconsistent, and it usually begins to mature in July. According to the color of the fruit, it will be harvested in time when the color of the fruit turns from bright red to black red. If it is not harvested in time, birds will eat Lonicera persicae fruit.

[0045] 2) post-ripening and storage of seeds:

[0046] 2.1) After the fruit is harvested, put the fruit into a nylon mesh bag and hang it in a ventilated and dry place to prevent the damp fruit from becoming moldy. Because the pulp is not peeled off at this stage, the seeds have a post-ripening process at this stage to improve the maturity of the seeds.

[0047] 2.2) Put the fully dried fruits into nylon mesh bags or paper bags and store them at 5°C. If there is no special low-temperature cabinet, they can be sealed ...

Abstract

The invention belongs to the technical field of sexual reproduction of plants and discloses a method of raising seedlings for Lonicera sempervirens seed. The method mainly comprises following steps: fruit harvesting; seed after-ripening and storing; seed soaking; seed pregermination; seed sowing; seedling potting, etc. According to the method, the time of after-ripening of Lonicera sempervirens seed is increased; low temperature treatment facilitates breaking of seed dormancy; Lonicera sempervirens seed germination is accelerated due to suitable temperature so that the time of seedling emergence is reduced. The method has following beneficial effects: tidiness of seedling emerging; simplicity of operation during seedling; ease of implementation. The method provides forceful foundation for breeding seeds and raising seedlings for Lonicera sempervirens. Commercialization application and promotion of the technology are facilitated.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to a method for raising seedlings, in particular to a method for raising seedlings of honeysuckle seeds. Background technique [0002] LonicerasempervirensLinn. belongs to the winding deciduous vine of the genus Lonicera. The flowers are in whorls, usually 6 flowers per round, and 2 to several rounds form terminal spikes. The corolla is neat, slender and funnel-shaped, red on the outside and flowers on the inside. It is orange-yellow at the beginning, and turns red later; the fruit is red. Honeysuckle is native to North America and is now cultivated in some cities in my country. It has rapid growth, bright colors, long flowering period, good ornamental effect, and excellent characteristics such as heat resistance, drought resistance, and salt and alkali resistance. It is suitable for garden rattans, Fences, moldings and green roofs. [0003] Lonicera vines are excellent thr...
