How much is a bunch of silver bud willow flowers of willow family? When is the cuttage? How to cuttage?

Silver bud willow, also known as silver willow, is a common plant in the northern region. It is widely planted because of its afforestation, greening and other effects, and it can be dyed, so many people put it indoors to improve the decorative effect. How much is a bunch of silver bud willow flowers? When is the cuttage? How to cuttage?

Bouquet price:

Generally 10 yuan a bunch, but there is a tree limit, but if you buy more, the price is not the same, specific can go to the major markets for consultation.

Cutting time:

The cutting time in Northeast China is in spring. Because Yinliu likes light, temperature, moisture, and likes fertile, loose and moist soil, it is just right in spring.

Cutting skills:

1. Land preparation

The land with flat terrain and fertile humus was selected for soil preparation, because silver willow liked fertilizer, sufficient base fertilizer was applied before soil preparation, and the base fertilizer was mainly rotten organic fertilizer, mainly cow, sheep, horse and chicken manure. After fertilizing, the root system of Salix mandshurica is well developed, which requires deep ploughing 45cm, raking flat and fine, picking up impurities such as stones and roots, making large ridge, wide 50cm and high 35cm. Autumn soil preparation, conditional plots, soil preparation and watering one time.

2. Insert bar

The northeast region chooses spring to cut cuttings. Select the branches with strong growth, full branches, full leaf buds, no diseases and insect pests and diameter in 1~3cm, cut cuttings, cut into 18~22cm length, each cuttings have at least 3 leaf buds, cut cuttings must pay attention to protect cuttings from skin injury. After cutting, put it in a cool place to be dealt with. The plug is used for backup.

3. Cutter treatment

Treatment of cuttings with naphthylacetic acid (NAA) before cutting can greatly improve the survival rate of cuttings. Treatment method: the solution of 40mg/L was prepared with naphthalene acetic acid (NAA). The solution was put into the solution according to the cutting position and soaked for 3 to 5 hours. The soaking time could be determined according to the degree of Lignification of cuttings. The better Lignification cuttings were longer.

4. Cuttage

The cutting time in Northeast China is spring. The treated cuttings are cut according to the row spacing 25cm, the plant spacing 15 bed surface, the oblique angle 45 degrees, the cutting depth is more than 3 buds to be exposed as the standard, in the arid area and sandy nursery, the upper end of the cuttings is flat with the ground, in order to prevent water evaporation, the upper end of the cuttings can be covered with soil, when it is about to germinate, remove the covered soil. After cutting, press the soil around the cuttings, combine the cuttings closely with the soil, water them once, and then spray the noodles with 0.5% carbendazim solution for disinfection to prevent bacterial infection. In order to avoid the death of cuttings caused by strong light, sunshades need to be built.

Plug-in management

1. Remove the shed. When it is determined that the cuttings survive, the technology removes the awning, transmits light, increases the temperature, and promotes the growth of cuttings.

2. Watering. Water should be watered enough after cutting, and if it is not enough for one time, it should be watered for the second time. When the cuttings have not taken root, the soil moisture content should be kept at 65% ~ 70%, and the moisture should be adjusted according to the weather and soil business conditions.

3. Loosen the soil. After each watering, it is necessary to loosen the soil in time and maintain good permeability to facilitate rooting. Avoid the hardening phenomenon in the seedbed soil.

4. Weeding. Weeding is carried out in combination with loosening the soil, and the principle of weeding is to remove early and small. Don't hurt the seedlings when weeding and loosening the soil.

5. Topdressing. When the cuttings take root and the seedlings survive, nitrogen fertilizer should be applied twice in time to promote root growth, and nitrogen fertilizer 35kg should be applied per mu. Before the arrival of autumn, topdressing phosphate fertilizer once and applying phosphate fertilizer 20kg per mu can also apply nitrogen, phosphorus and potassium compound fertilizer and 25kg per mu in the early survival stage of cuttings.

6. Removing tillers and wiping buds. When there are more twigs in cuttings, in order to concentrate the nutrition of seedlings and accelerate the growth of strong seedlings, it is necessary to remove tillers and sprouts in time to ensure the survival of cuttings.

7. Pest control. Diseases and insect pests in the early stage of cuttings rarely occur, mainly to prevent. During cutting, 5% potassium permanganate is used to clean the cuttings and spray the seedbed for disinfection. After cutting, the soil was disinfected with 1000 times of carbendazim. After 1 week of cutting, check the cuttings in time, if there are rots and diseases and insect pests, remove them in time.
