How to cut osmanthus best?

Everyone who raises osmanthus knows that osmanthus fragrans can be propagated by cutting, but how to cut osmanthus fragrans may not be known. The following summarizes the cutting operation steps and methods of osmanthus fragrans.

How to cut osmanthus?

1, soil cutting selection

Osmunda japonica cutting soil is generally sandy loam with deep soil layer, loose soil, sunny and leeward or calcareous soil rich in humus.

Before cutting, flower friends need to disinfect the soil. Generally, 5 days before mowing, 2-3% ferrous sulfate aqueous solution can be sprinkled on the bed surface, with 5 kg of liquid medicine per square meter;

Or dilute 400 times with 40% formalin solution 3 days before cutting, spray it on the bed with a penetration depth of 3-5 cm, and then cover it with plastic film. Uncover the film after 1 week, and then cut it after 2-3 days.

2. Selection of cutting branches

Generally speaking, cuttings of Osmunda japonica Thunb. Annual branches that are robust, completely lignified and free from pests and diseases should be selected. If hard cuttings are carried out in spring, flower friends need to store them in winter.

Storage method: Huayou can cut the branches into about 15cm, choose a shady place with high terrain and good drainage, and dig a ditch with a width of 1cm and a depth of 60-80cm.

First, lay a layer of 5cm thick wet sand at the bottom of the ditch, and put the cuttings into a bundle of 50 branches in layers in the ditch. When the main cuttings are placed 20cm above the ground, fill them with wet sand, cover them with soil to form a roof, and put a straw handle in the middle to facilitate ventilation.

3. Cutting method

6-8 days before cutting, the cuttings can be soaked in running water. If it is stagnant water, the water must be changed every day until the obvious irregular tumor appears at the cutting incision, and then the cutting can be carried out. Of course, it can also be soaked in 1% sucrose solution for 24 hours, which can significantly improve the survival rate.

Before cutting, apply sufficient base fertilizer to the bed to be cut, and the water content should be sufficient. Then, directly make a hole with a tool, insert branches along the hole, and then seal the hole tightly. The cutting depth is 2/3 of the cutting length, the plant spacing is 10cm, and the row spacing is 15cm. After insertion, pour water.

4. Maintenance and management after cutting

After the cutting of Osmunda japonica is completed, the seedbed must be covered with plastic film, sealed with soil, and covered with sunshade net. Generally, cutting can take root in about three weeks.

After the cuttings take root, the mulch can be removed in batches. In addition, the seedbed should be kept moist after cutting, and watered with small water and clear water at seedling stage to make the seedbed permeate and avoid flooding.

Irrigation 1 time every 3 ~ 5 days. Quick-acting fertilizer should be applied after 40 days of cutting, and the principle of fertilization by stages should be mastered. Regularly weed and loosen the soil artificially.

Small seedlings should be shallow and big seedlings should be deep. Generally, the depth of loosening soil is 2 to 4 cm, and then it is increased to 8 to 10 cm.

5, seedling transplantation

Generally, seedlings can be transplanted in early April of the following year. First, water Miao Di to make it permeable, and then plant spacing is 20cm× 40cm. After planting, water 1 time for root setting. After that, tillers should be pulled out and pruned in time to keep strong branches, and the general dry height is 1.5-2m. ..
