Leaflet Rhododendron Breeding Technique
Cuckoo is a special species with small leaves and a flowering period from March to April. Therefore, it can be inferred that the larger is likely to be Dongyang, and the possibility of Xiqiao is not excluded. Because the seed particles of azaleas are extremely small, they are very strict for sowing seedlings, including soil disinfection, air humidity guarantee, etc., and are not easily met under family conditions. It is recommended to use cutting methods. If stocks are available, grafting can also be used.
From May to June, you can choose the shorter half-timbered branches in the current year. Cut from the base for cuttings, and keep 3 to 5 leaflets at the top. If the branches are too long, you can cut off the tips. The cutting media can be used orchid mud, alpine humus, vermiculite, perlite or yellow heart soil, thickness of about 15 cm to 20 cm, laid a drainage layer of 7 cm to 8 cm; after the medium is wet, insert the cuttings into the matrix In the cuttings, the depth of the cuttings is about 1/2 of the ear length, and a small amount of cuttings for the family can also use large flower pots to hold the cuttings for seedlings. After plugging, the plastic film is moistened, the temperature is controlled between 25° C. and 30° C., an arboure is installed to block the sunlight, or placed under the shade, and the cutting substrate is always kept moist. The east wolfberry can take root after about 1 month. , while Xiqiao will take 60 days to 70 days to take root. After 9 months, the shade time can be reduced, and the thin urea solution can be top-dressed once, with a concentration of about 0.2%. The pots can be put on in late October. In the production of full-illumination electron intermittent spray device cutting, with vermiculite as a cutting matrix, after 20 days to survive, the general survival rate of up to 95%.
In addition, it is worth mentioning that: in the northeast of China, Inner Mongolia, Russia, and North Korea, there is also a wild R. parrifolum, which is an evergreen shrub with a rose-colored corolla, which is inconsistent with the many colors you describe. , it can be ruled out.
Food additives refer to chemically synthesized or natural substances added to food in order to improve the quality, color, aroma and taste of food, as well as for the needs of antiseptic and processing technology. Due to the rapid development of the food industry, food additives have become an important part of the modern food industry, and have become an important driving force for technological progress and technological innovation in the food industry
