Vaccinium bracteatum is a common tree in southern China, also known as Nanzhuang, Zero Queena Ding and Jinniu. Its leaves are often used for cooking in southern China, so it is named Vaccinium bracteatum. Vaccinium bracteatum L. has beautiful appearance, long flowering period and ornamental value. So can Vaccinium bracteatum be planted on a large scale? How to plant Vaccinium bracteatum? Here, the scientific development of agriculture is used to illustrate this problem.
What is a Vaccinium bracteatum?
Vaccinium bracteatum may be strange to friends in the north, but it is familiar to friends in the south. There is a custom of eating Vaccinium bracteatum for cooking in the south. It is usually eaten on the third day of March or the eighth day of April in the lunar calendar. Vaccinium bracteatum is called "Vaccinium bracteatum" because the leaves of Vaccinium bracteatum contain natural melanin, which can dye rice black and has certain antiseptic effect. People in southern China have the custom of eating Vaccinium bracteatum, hence the name Vaccinium bracteatum.
Vaccinium bracteatum belongs to Ericaceae. It is about two to six meters high, with many branches, oval leaves, terminal and axillary racemes, and lovely white and red flowers. The fruit is a berry, purple-black, much like blueberry fruit. Vaccinium bracteatum has strong ornamental value. Many friends like to use Vaccinium bracteatum as bonsai, and some places will also be used as urban greening trees.
How to plant Vaccinium bracteatum?
After understanding the basic information of Vaccinium bracteatum, some friends will ask how to plant Vaccinium bracteatum. Here, the scientific development of agriculture will talk about the cultivation of Vaccinium bracteatum from three aspects: growth habits, planting methods and daily management.
Growth habit: Vaccinium bracteatum grows in the wild and has strong adaptability. It likes warm and humid growing environment, likes sunshine, is tolerant to shade, drought, barren and cold, and can grow well in mountains and roads. Vaccinium bracteatum grows in the south of the Yangtze River in China, as well as in North China and East China. Judging from the growth habits of Vaccinium bracteatum, Vaccinium bracteatum can be planted in most parts of China.
Planting method: Vaccinium bracteatum L. has two main propagation methods, one is seed sowing and the other is cutting. Although Vaccinium bracteatum has strong adaptability, the propagation technology of Vaccinium bracteatum is still difficult, especially when it is planted by sowing, because the germination rate and seedling rate of Vaccinium bracteatum seeds are relatively low, so it is still difficult to raise seedlings of Vaccinium bracteatum. This paper mainly talks about the cutting method of Vaccinium bracteatum.
The rooting ability of Vaccinium bracteatum branches is poor, and the effect of hard branch cutting is worse than that of soft branch cutting, which is usually soft branch cutting. The cutting time is every spring, and the cuttings need to choose 1 to 2-year-old branches from 3-year-old to 5-year-old robust and disease-free mother plants. The cutting diameter should be 0.2 to 0.5 cm, and the cutting should be trimmed to a length of about 10 cm, with a flat mouth at the upper part and a horseshoe-shaped diagonal cut at the lower part.
After the cuttings are pruned, it is best to bundle 50 ~ 100 cuttings and put them in clear water to keep them moist. Before cutting, it needs to be dipped in rooting agent for disinfection. Rooting agent can be soaked in ABT rooting agent or IBA 200mg/L solution for1-2h. The disinfectant can be chlorothalonil or potassium permanganate.
The cutting substrate can be sandy soil, vermiculite and perlite with good air permeability. The cutting depth is 1/3 ~ 1/2 of the cutting length, the plant spacing is controlled at about 5 cm, and the seedbed is kept moist after cutting.
Daily management: Vaccinium bracteatum needs careful care after survival. Here mainly from the seedling management and fertilizer and water management to explain two aspects. After the cuttage of Vaccinium bracteatum is completed, the seedbed environment should be kept suitable, shaded in summer and kept warm in winter. To keep the seedbed moist, you can use a sprayer to spray water and loosen the soil and weed in time. Transplanting will be carried out from February to March next year.
Water and fertilizer management of Vaccinium bracteatum should be carried out according to the growth stage, and decomposed organic fertilizer can be applied appropriately in spring. Potassium dihydrogen phosphate can be sprayed before flowering to promote flower bud differentiation. After the Vaccinium bracteatum set fruit, attention should be paid to topdressing nitrogen and phosphorus fertilizer in time to promote fruit growth. In addition, Vaccinium bracteatum likes slightly acidic soil, and the soil in the northern area is alkaline, so ferrous sulfate can be used appropriately in the soil to improve the soil acidity and alkalinity. Vaccinium bracteatum is drought-tolerant and the soil should not be too wet. The spunlace depends on the soil and weather, and should be thoroughly dried.
