Problems solved by technology

However, rhododendron seeds have thick seed coats and hard seed embryos, which require special substrates and growth environments, and are prone to infection of germs and insect damage during seedling cultivation. Therefore, rhododendron seeds are not easy to germinate and have low survival rates.
When currently cultivating rhododendrons with the method of sowing, the seed coats are often removed, cut or knocked open to improve the survival rate of the seeds, but this operation is easy to cause damage to the seed embryos, and it is time-consuming and laborious. Rhododendron seedlings bring great difficulty and increase the cost of Rhododendron seedlings

Embodiment 1

[0025] A seedling raising method for improving the survival rate of rhododendrons. The seeds of rhododendrons collected in the mature stage of the year are selected to be sterilized, pretreated, and then sown, and the seeds are germinated under daily management. The specific steps of the pretreatment are: The finished seeds were soaked in a sodium hydroxide solution with a mass concentration of 35g / L for 30 minutes, then the seeds were taken out and dried, and then the seeds were placed in the treatment agent and soaked for 16 hours. After soaking, the seeds were taken out and spread on the Dry in a cool and dry place, then take 80 parts by weight of the dried seeds and 20 parts of the coating agent and mix them, then spray 0.5 times the total weight of the coating agent and seeds into water, stir for 30 minutes and then place it in a dry place Dry in the machine at 40°C for 12 seconds;

[0040] A seedling raising method for improving the survival rate of rhododendrons. The seeds of rhododendrons collected in the mature stage of the year are selected to be sterilized, pretreated, and then sown, and the seeds are germinated under daily management. The specific steps of the pretreatment are: The finished seeds were soaked in a sodium hydroxide solution with a mass concentration of 35g / L for 32 minutes, then the seeds were taken out and dried, and then the seeds were placed in the treatment agent and soaked for 17 hours. After soaking, the seeds were taken out and spread on the Dry in a cool and dry place, then take 85 parts by weight of the dried seeds and 25 parts of the coating agent and mix them, then spray 0.5 times the total weight of the coating agent and seeds into water, stir for 30 minutes and then place it in a dry place Dry in the machine at 42°C for 13 seconds;

Embodiment 3

[0055] A seedling raising method for improving the survival rate of rhododendrons. The seeds of rhododendrons collected in the mature stage of the year are selected to be sterilized, pretreated, and then sown, and the seeds are germinated under daily management. The specific steps of the pretreatment are: The finished seeds were soaked in a sodium hydroxide solution with a mass concentration of 35g / L for 35 minutes, then the seeds were taken out and dried, and then the seeds were soaked in the treatment agent for 18 hours. After soaking, the seeds were taken out and spread on the Dry in a cool and dry place, then take 90 parts by weight of the dried seeds and 30 parts of the coating agent and mix them, then spray 0.5 times the total weight of the coating agent and seeds into water, stir for 30 minutes and then place them in the dry place Dry in the machine at 43°C for 14 seconds;

Abstract

The invention provides a seedling raising method for improving the survival rate of Rhododendron. The seeds, collected in mature period in current year, of Rhododendron are disinfected, sowed after a pretreatment and managed daily in sequence until the seeds sprout. The pretreatment includes the steps of soaking the disinfected seeds in sodium hydroxide solution with the mass concentration of 35g / L for 30-40min, then taking out the seeds for draining and drying, soaking in a treating agent for 16-20h, taking out the seeds after soaking, spreading in a cool and dry place for drying, mixing the dried seeds of 80-100 parts by weight with a coating agent of 20-40 parts by weight, spraying water, wherein the weight of water is 0.5 times more than the total weight of the seeds and the coating agent, stirring for 30min, and drying in a dryer at 40-45 DEG C for 12-16s. The seedling raising method for improving the survival rate of Rhododendron has the advantages of time saving, labor saving and low cost, the batch processing is easy to achieve, and the survival rate of Rhododendron seeds is greatly improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a seedling raising method for improving the survival rate of rhododendrons. Background technique [0002] Rhododendron, also known as azalea and pomegranate, is an evergreen or ordinary green shrub. Rhododendron generally blooms in spring, with 2-6 flowers per cluster, funnel-shaped corolla, red, light red, apricot red, snow green, white, etc., with luxuriant and bright colors. It is a typical acid soil indicator plant in south-central and southwest China. The whole rhododendron can be used for medicinal purposes. It has the effects of promoting qi and blood circulation and nourishing deficiency. It can treat internal injury cough, kidney deficiency and deafness, irregular menstruation, rheumatism and other diseases. Because of its bright red corolla, it is a famous flower plant with high ornamental value. [0003] Rhododendron can be propagated by cutting, grafting, ...
