Cutting techniques of eight Immortals

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, Although the eight Immortals have been cultivated for many years, they are still popular. However, in recent years, due to the aging of varieties and serious illegal reproduction, the price of finished flowers is low. To some extent, the cultivation of new varieties of eight Immortals has increased the market demand and improved the competitiveness of the majority of growers. The coming March to May is the main planting period for the seedlings of the eight Immortals, in preparation for the listing of New Year's Day and the Spring Festival next year. The following focuses on some management points after the arrival of New Year's Day's rootless seedlings listed on the market. First, prepare before arrival.

The following focuses on some management points after the arrival of New Year's Day's rootless seedlings listed on the market.

First, prepare before arrival

1. Greenhouse conditions

Solar greenhouse or modern glass greenhouse can be, but there must be fans, water curtains, heating and other rising and cooling facilities.

two。 Acupoint plate

Use the acupoint plate of 50 or 35 acupoints.

3. Matrix

It is generally required that the cultivation medium has good ventilation, water-holding capacity and buffering performance, and is relatively stable. The matrix mixture without peat and clay can be used in production. The seedlings treated with perlite and humus soil with the mixture ratio of 1 Zhao 2 were the strongest. Red and pink varieties require the pH value of the matrix to be 5.5 to 6.0. The suitable pH value of blue and white varieties is 3.5 to 4.0.

4. water

Rain Water (or the mixture of tap water and Rain Water) is an ideal irrigation water (the pH value is about 7).

Second, cuttage

It takes about 35 weeks for the eight Immortals to go from rootless seedlings to market, and the finished products listed by New Year's Day need to be cut in late March or early April the year before. It is ideal for cuttings to take root in seedling tray or in a single seedling bag. But the key to success lies in the selection of the substrate, we must ensure that the selected substrate is not too hard, in order to facilitate the rooting of cuttings. The eight Immortals are very sensitive at the rooting stage.

III. Rooting conditions

1. Temperature

When rooting, the temperature is kept at 18 ℃ to 20 ℃, and the environment with high humidity is ideal, especially after cutting. Because if the temperature of the substrate is too high, the root growth rate will slow down, or even stop; while the temperature is too high, the plant stem will be slender and thin, and the root system may stop growing.

two。 Light, humidity

It is necessary to properly shade and strengthen management after cutting. the general air relative humidity is 80% to 90%. When the seedlings grow for 20 to 25 days, the root system can be filled with nutrition bowls or holes.
