Obscene fruit is a kind of plant with high ornamental value. In addition, it is also a national third class protected plant, which is very precious. The plants are compact, the trunks are clumped, the posture of the clumps is beautiful, and the flowering time is just at the time of withering in early summer, so it is more valuable. So what is the breeding method of obscene fruit? Let's look down together~
Breeding method of hedgehog seed breeding method of obscene seed (basic knowledge): the best breeding time: the best breeding time of obscene seed is from July to August;
The best growing soil: most of the soil is brown, showing slightly acidic to slightly alkaline reaction. On the sunny slope with thin soil layer and bare rock, the plants can grow normally, while on the wetland, the lateral roots are easy to rot and gradually die;
Requirements for growth humidity: humidity should not be too high. In places with too high relative humidity and heavy rainfall, it often grows poorly and is prone to diseases and insect pests;
The best growth temperature: the main distribution area of the fruit is dry and cold in winter and spring, hot and rainy in summer and autumn. The extreme minimum temperature can reach - 21 ℃, the annual average temperature is 12-15 ℃, and the annual precipitation is 500-1100 mm;
Best growth light: I like plenty of sunshine, but don't expose to the sun.
Breeding method of Hedgehog: fertilizer application:
It is better to apply a certain amount of base fertilizer, nitrogen fertilizer in growth period, phosphorus and potassium fertilizer in late autumn, and organic fertilizer once decomposed in autumn to ensure the growth and development of flower buds and promote their blooming.
Watering points:
At seedling stage, the soil should be kept moist and weeding should be done frequently. In the growing season and dry weather, we should pay attention to timely watering, and carry out intertillage and weeding to enhance soil permeability and prevent soil hardening. After transplanting, the seedlings were continuously watered for 4-5 times with an interval of 7-10 days. Attention should be paid to drainage in rainy season, and stagnant water is easy to cause rotten roots.
Pruning tips:
In fact, the dead branches, diseased branches and dense branches should be cut in early spring every year. After flowering, prune appropriately, leave 4-5 full buds on the flowering branches and cut them short to promote the development of new branches for flowering in the next year. In summer, the new branches of the same year were pinched properly to promote flower bud differentiation. In the daily management, cut the dense branches, redundant sprouts, overlapping branches, pest branches and disabled branches to make them ventilated and transparent. Generally, 6-10 strong branches are left in each cluster, and the rest are removed. In order to keep the shape of the tree in order, it can be cut again every time according to the specific situation, so as to germinate new branches, control the plant cluster, and keep the tree shape compact, so as to avoid the flower position moving out year by year due to too long branches.
Breeding methods of Hedgehog
Breeding points:
Hedgehog seeds are usually propagated by sowing, cutting, splitting and layering.
Sowing: the ripe fruits should be harvested in September, and the seeds should be stored in wet sand layer for Tibetan dragon to live in winter, and germinate neatly after spring sowing.
Cutting: the thick dormant branches can be selected in spring, or the semi lignified tender branches can be used in June to July for cutting in open seedbed, which is easy to take root and survive.
Ramets: ramets can be planted in spring and autumn, and can be planted in spring after autumn, so it is easy to survive. Seedling transplanting can be carried out from the time of falling leaves in autumn to the time of germination in early spring of the next year. In rainy season, we should pay attention to drainage and prune properly after flowering, so as to make the flowers more colorful in the coming year.
The seeds which are easy to cultivate and germinated by sand storage are drilled from late March to early April, and the seedlings emerge in half a month.
Pest control:
Disease and pest control: Hedgehog disease and pest less. In 5-6 and autumn, there were occasional insect pests, which could be diluted by 800-1000 Omethoate 40% Omethoate. In addition, rust is also a common disease, we should strengthen the prevention and control.
Breeding methods of hedgehog expand knowledge - conservation status of Hedgehog: rare species, hedgehog is a unique single species and genus in China. Due to unreasonable reclamation and overgrazing, as well as frequent logging, vegetation damage, resulting in habitat deterioration, poor natural regeneration, plants are becoming increasingly scarce. The lower limit of altitude is 350 meters, and the upper limit is 1340 (1900) meters.
Protect value. Hedgehog is an ancient relic from Qinling to Dabie Mountains. Because of its special morphology, it is isolated in the family loniceraceae. It has a certain scientific value for the study of flora, paleogeography and the phylogeny of loniceraceae. Hedgehog is a kind of flower with high ornamental value.
Protection measures. A nature reserve has been established in Shennongjia, Hubei Province, and hedgehog is one of the key objects in Jiyuan macaque reserve in Henan Province. It is introduced and cultivated in Beijing Botanical Garden of Chinese Academy of Sciences and European and American Botanical Garden. It can be propagated and cultivated in the suitable area of the distribution area.
