It needs to be further explained that: in autumn of the year, the best time for covering 10-20 cm of soil on the grafting opening part of the grafted seedling is before the temperature is reduced to 2 ℃. In addition, secondary rooting of the scion (hibiscus) at the upper part of the inferior spring grafting opening is prevented, and the salt tolerance is reduced; on the land with the soil salinity lower than 4 per mill, the soil covered in the last autumn is removed in the next spring.
Meanwhile, it is to be noted that: after a batch of salt-tolerant hibiscus cultivated by the cultivation method is examined at the low temperature of minus 16 ℃ for 48 hours in winter of the current grafting and planting, the result shows that the survival rate of the grafted salt-tolerant hibiscus seedlings reaches more than 95%.
In the cultivation method, the scion is collected in a dormant period, the scion is collected from a strong and disease and insect pest free annual spring tip or a middle section of a summer tip of the hibiscus syriacus, and the diameter of the scion is 0.6 cm-1.2 cm; because the scions cannot be used for grafting immediately after collection, the scions need to be stored after collection under the following storage conditions: the scions are sealed by wax and then placed in plastic bags or sand stored in sand with the water content of 40-50%, and the temperature is maintained at 1-5 ℃.

In the above cultivation method, grafting is performed from mid-2 to late-3 months; cleft grafting or double-tongue grafting is selected for grafting, and the grafting process when double-tongue grafting is selected is as follows: (1) cutting the scion, cutting a large inclined plane with the length of 2 cm-3 cm from the lower bud of the scion to the lower part, and upwards cutting a socket with the depth of 1 cm-2 cm at the upper 1/3 part of the inclined plane; (2) cutting a stock, and cutting an oblique grafting opening with the length of 2-3 cm at the upper end of the stock by using a sharp blade, wherein the grafting opening is an oblique plane; a socket with the depth of 1 cm-2 cm is cut downwards at the position 1/3 below the inclined plane, the distance between the socket and the socket on the scion is equal, and the grafting socket and the inclined plane on the scion are cut flat; (3) inserting the scion, aligning the insertion opening on the scion with the insertion opening on the stock, aligning the cambium on at least one side of the scion with the cambium on the stock, and inserting and tightly inserting the scion from top to bottom; (4) sealing the grafting opening, and winding and binding the grafting opening with a grafting film or a polyvinyl chloride plastic film with the width of 2-3 cm to ensure that the grafting opening cannot be ventilated; planting the grafted seedlings in a nursery, a flowerpot or a nutrition pot; or the grafted seedlings are buried in wet sand and stored indoors and are planted after the air temperature is warmed up. In addition, it should be noted that: after the grafting opening of the grafted seedling is healed, the grafting film or polyvinyl chloride plastic film of the grafting opening needs to be removed.
In the cultivation method, after the grafted seedling survives, the rootstock sprout tiller needs to be removed in time, the robust part at the upper part of the sprout strip extracted from the scion is reserved for the sprout strip to continue growing, and the rest sprout strips are removed; when the nursery stock enters a fast growing period, intertillage weeding and topdressing are carried out, fertilizers are applied once in spring, summer and autumn, 10 kg/mu of urea and 10 kg/mu of compound fertilizer (N: P: K =15:15: 15) are applied in spring and summer, and 10 kg/mu of compound fertilizer (N: P: K =15:15: 15) are applied in autumn; when the borer is harmful, 10% imidacloprid 1000-fold liquid is sprayed once and is repeated once after one week.
The emergence of the salt-tolerant hibiscus syriacus seedlings is carried out before the autumn soil is sealed and frozen or in early spring, and the seedlings are comprehensively investigated or spot checked; selecting nursery stocks with the height of more than 40cm, the root length of more than 20cm, the number of roots of more than 4, strong growth, no plant diseases, insect pests and mechanical damage, and grading according to the national nursery stock specifications; when digging seedlings, the seedlings are dug slowly and deeply, the root system is kept complete, and soil balls can be carried conditionally; the bare-rooted seedlings are temporarily planted or dipped in slurry immediately after being lifted, transported externally, packed by straw bags or other packing materials and rapidly transported to the destination.
