How much is the price of holly seedlings? What are the key points of planting techniques?

Holly originated in China, mainly distributed in China and eastern India and Southeast Asia, but there are not many plants in China, and holly is encouraged in many places because it has strong resistance and absorption capacity to soot and toxic gases. It is especially suitable for hedges, green walls or landscape planting in cities. It is the preferred tree species for airport, highway, residential greening, factory greening, shelterbelt, courtyard greening. Because of its strong fire resistance, it can be used as a forest fire barrier. How much is the price of holly seedlings? What are the key points of planting techniques?

Second, what are the key techniques for planting holly seedlings?

1. Seedling transplanting

The seedlings are 1.5 cm tall. When real leaves appear, they are moved into a plastic bag nutrition bowl and discharged into the seedbed. The plant spacing is 6 cm, the row spacing is 12 cm, the caliber of the plastic bag is 5 cm, and the bowl height is 10-12 cm. After moving in, the seedlings are afraid of high temperature and sunburn and drought, so it is necessary to set up a sunshade with a net of 75% shading in time to shade and moisturize.

2. Fertilization

It is mainly fertilized during the peak period of seedling growth. In April, 0.1-0.3% solution of calcium superphosphate and potassium dihydrogen phosphate were sprayed on leaves every 5 days to promote root growth and development and stem Lignification. 0.1% urea was sprayed on the leaves every 5 days from July to August. In the later stage of seedling growth, 0.3% potassium dihydrogen phosphate solution or 0.2-0.3% potassium sulfate solution was sprayed on the leaves every 5-7 days to promote the Lignification of seedlings and enhance the overwintering cold resistance.

3. Guard against cold

Increase the application of potassium fertilizer after autumn to promote the Lignification of seedlings. In the later stage, the shading time should be shortened appropriately. From the first ten days of September, gradually remove the shade net and increase the light. Before the extreme temperature in winter, build an arch shed to cover the film to protect against cold and seedlings.

4. Pest control

Although there are few diseases and insect pests in holly, there is no need for prevention and control. Whether it is greening or tea production, they all advocate comprehensive prevention and control and emphasize the protection of the environment. First of all, fine pruning, timely removal of disease and insect branches, dead branches, inner hall over-dense branches. Through the reasonable adjustment of the tree body and inter-tree structure, the ventilation and light transmission conditions were improved, and the living environment of diseases and insect pests was deteriorated. Secondly, the use of biotechnology to eliminate pests, the use of natural enemies, the use of artificial feeding, introduction and other measures to increase the number of natural enemies and control the number of pests. Third, promote the use of biological pesticides, including microbial pesticides, animal pesticides, botanical pesticides and so on. Fourth, mineral pesticides such as Bordeaux solution and stone-sulfur mixture can be used if necessary.
