So, when is the pruning time of arhat pine? Do you know the method of pruning? How does it breed? What is the breeding method? Let's have a look.
The pruning time of Podocarpus is 1. When we prune Podocarpus, no matter how we prune it, we must follow the growth law of Podocarpus.
Moreover, Podocarpus is a plant that needs pruning all the year round. Only in this way can we ensure that the arhat pine grows luxuriantly and is brightly green.
2. Although we say that Podocarpus is a plant that can be pruned all year round, the most suitable time for pruning Podocarpus is between July and August every year.
Pruning method of Podocarpus 1, thinning method We are thinning Podocarpus, that is, cutting the branches of Podocarpus from the base, and then making the stumps ventilated and transparent, which can concentrate the nutrient supply of Podocarpus and make Podocarpus grow more vigorously.
It is also beneficial to the normal development and accelerated molding of Podocarpus.
No nutrients are consumed, which affects the growth of tree potential.
2. Short-cut pruning of Podocarpus fargesii is to cut off the long branches of Podocarpus, and then stimulate the axillary bud germination under the incision with short-cut method, thus forming better lateral branches and promoting the branching of Podocarpus, which can be beneficial to the modeling of Podocarpus.
What is the breeding method of arhat pine? The propagation of Podocarpus is mainly carried out by cutting, which is mainly divided into softwood cutting and hard wood cutting.
Different cutting methods adapt to different periods and methods.
In order to adapt to the propagation of Podocarpus, corresponding operations should be carried out according to the cutting methods used, so as to ensure the survival rate of seedling cutting.
In the first half of the year, softwood cutting was carried out from mid-late May to early July, and in the second half, it was carried out from mid-late August to mid-late September.
The seedlings planted in the first half of the year should pay attention to preventing high temperature and diseases.
The seedlings planted in the second half of the year should pay attention to heat preservation and antifreeze in the middle and late stages. The time to open the sunshade net is165438+1late October, and the time to open the sunshade net in dry years can be extended to 65438+late February.
Hardwood cutting.
Hard-branch cutting refers to the method of cutting thick branches that were completely lignified in the previous year during the dormant period of liquid flow in early spring from February to March.
This method is mainly suitable for deciduous trees such as crape myrtle, hibiscus, grape, poplar and willow. Some evergreen trees can also be cut with hard branches, such as oleander.
Attention should be paid to raising the soil temperature and controlling the temperature in the shed in early spring.
In a word, whether it is softwood cutting or hardwood cutting, cuttings and soil should be covered, and the temperature, humidity and light of the seedbed should be controlled well.
In addition, in order to improve the survival rate of seedling cutting, some measures should be taken to promote rooting.
Always check the nursing seedbed after cutting to see if the film and sunshade covered by the seedbed are bitten by insects and rats and blown away by the wind.
Uncover the film and sunshade net every 15 days, spray pesticides to kill insects, and then cover the film and sunshade net again.
If the seedbed soil is found to be dry, sprinkle some water before spraying, and then spray pesticides after the leaves are dry.
Generally, after uncovering the film for 2 ~ 3 times, the cuttings have taken root and survived, and then they can be sprayed once every 1 ~ 2 months.
After the cuttings survive, you can consider uncovering the film.
Before formally uncovering the film, it is necessary to choose rainy days, first uncover the film at one or both ends of the seedbed and let the seedlings ventilate for a few days, and then completely uncover the film.
After uncovering the film, the sunshade net still needs to be covered.
For the seedlings cut in the first half of the year, the shading net can't be removed until late autumn, because the seedlings can't stand strong light.
It is particularly worth mentioning that both Ligustrum lucidum and Ligustrum lucidum are susceptible seedlings, and the film should be uncovered in time. Generally, about 20 days after transplanting, about 90% can take root and begin to harden and uncover the film. After uncovering the film, spray it once to prevent disease, once every 7 ~ 10 days, and then spray it 3 ~ 4 times.
The above information is about pruning time, pruning method and propagation method of Podocarpus provided by Bian Xiao. I hope the above information can help you.
