First, from May to June, this period is the direct cutting period;
Second, after 1 October1,this period is suitable for cutting on the ground.
Cutting method of zinnia
A, direct cutting method:
Preparatory work:
1, prepare topsoil.
Bairihong prefers fertile soil, so we need to add decomposed organic fertilizer to ordinary soil to make topsoil.
2. Prepare to cut the material.
We need to select healthy branches from the normal growth of zinnia, trim them to the length of 10 ~ 15cm, and cut them from the middle position of about 3 ~ 4cm.
3. Prepare cutting tools.
Cutting requires the use of complex cutting knives to avoid damaging the roots of plants.
4. Prepare the cutting pot.
We need to prepare a wide and shallow cutting basin with a layer of sand. Sand mainly plays the role of water conservation and contributes to the success of cutting.
step
1. First, connect the cut zinnia bud to the tip of the cutting knife.
The incision should not be too big, so as not to hurt the plants.
2. Make a shallow "cut" on the topsoil with a cutting knife, pinch the bottom of the cut material at a certain angle and insert it into the cheese.
3. After the cutting is completed, water is gently sprayed on the cutting material by a sprayer to keep the topsoil wet but not soaked.
4. Put the jar in a cool and well-lit place.
Second, Voldemort's cutting method
Preparatory work:
1, prepare soil. Voldemort cutting needs a nutrient-rich culture soil, and urea and potassium fertilizer can be used to increase the fertility of the culture soil.
2. Prepare to ambush the scene. The coverage site needs to be deep enough to ensure that the water has passed, and the surface should be covered with a layer of clean sand, so that one third of the cuttings are exposed to the ground.
3. Prepare to cut the material. As mentioned above, we need to select healthy branches from the normal growth of zinnia, trim them to 10 ~ 15cm, and cut them off or cut them off from the middle position of about 3 ~ 4cm.
step
1. Insert the selected cutting materials into the underground tray one by one, and make the bottom contact with the soil to a certain depth.
2. In the process of cultivation, we should pay attention to ensure that the surface of Voldemort's cut pieces will not be dry. This requires us to spray water and pour water regularly.
3. After each zinnia grows a piece of new green, a layer of cement pressure plate should be pressed on the cutting piece to make it compressed.
abstract
In the process of cutting propagation of zinnia, it is necessary to pay special attention to the health status of plants, which is very important for the survival rate of cutting. At the same time, we need patience. It takes time to accumulate experience. Only by accumulating rich experience can we contribute more to the success of cutting. Finally, we should pay attention to the maintenance and management during cutting to ensure the growth environment and conditions of zinnia after cutting.
