Cutting techniques of Rose in Winter

From the middle of October to the first ten days of November, the branches with symmetrical and hidden buds were selected according to the overwintering pruning of rose, the leaves were removed and cut into cuttings 10 cm long (about 3 nodes). The upper end was cut into a flat mouth, sealed with paint, and the lower end was cut into a slant.

two。 Preparation of nursery bed and nutrition bag

Choose a piece of land with a leeward to the sun, flat terrain and loose soil to make a seedbed with a width of 1 meter, a length of 6 meters and a depth of 20 mi 30 cm. Half-mix the mature nutrient soil and fine sand soil into soil moisture, disinfect it with zinc parathion and carbendazim and put it into a nutrition bag for spare; it can also be spread directly on the seedbed without a nutrition bag.

3. Cuttage

When inserting, put the nutrition bags on the seedling bed one by one. Pierce the eye with sticks or chopsticks, and then insert the insert, deep 1 to 2, 2 to 2, and 3 to compaction. Note: do not invert, prickle down, bud up, while inserting while watering, after insertion, pour water thoroughly. Then, stick on the seedbed, cover the film, and press it around with soil.

4. Plug-in management

4.1 if the weather is sunny and the temperature is high, the film at both ends of the seedbed should be opened at noon and ventilated. Otherwise, sunburn is easy to occur and a lot of people die at the beginning of spring. In the middle of November, seal the film.

4.2 after watering, removing the film and inserting it thoroughly, it will not be watered again. If the soil skin is white, you can sprinkle water properly.

A frozen layer is formed underground after winter, and the seedlings are not short of water. Observe the seedbed temperature when Rain Water and the Waking of Insects, and ventilate in time when it is higher than 20 ℃, otherwise it is easy to beaker seedlings. The film is gradually removed when the seedlings spread their leaves.

4.3 Insecticidal in late March to early April, insert buds of about 1 cm, easy to be attacked by aphids, should pay attention to prevention of aphids, can be fumigated with 80% dichlorvos, that is, 2 square meters to insert five cotton balls with medicine about 0.6 cm in diameter, removed in 2 hours. One week later, it was observed that if there were worms, they would be inserted again. At this time, special attention should be paid to insect pests, otherwise it will do great harm to seedlings.

5. Matters needing attention
