How to propagate Pinus elliottii and fertilization method

Luo Hansong must be no stranger to it, and we can often see it in our life. The ornamental value of Luohansong is very high, the leaves are evergreen all the year round, and it is the main ornamental point. Now many people like to breed it, so it is necessary to find out its breeding methods and fertilization skills before breeding.

How does Luohansong reproduce?

1. Sow seeds. The sowing of Pinus elliottii takes place in August every year. It can be carried out after the seeds are harvested in August. The growth of sowing seedlings is slow, it is necessary to keep the basin soil moist, and shade maintenance should be carried out in midsummer. Fertilization is mainly light fertilizer, too high concentration is easy to burn seedlings. When transplanting into the basin, the seedlings need to carry soil.

2. Cutting. Cutting refers to the cutting method of using semi-mature branches as cuttings in the growing season of seedlings, which is mainly suitable for evergreen and semi-evergreen woody flowers. The first half of the year usually takes place from mid-late May to early July, and the second half of the year takes place from mid-late August to mid-late September. Seedlings planted in the first half of the year should pay attention to prevent high temperature burns and diseases. Seedlings planted in the second half of the year should pay attention to the middle and later stage of heat preservation and anti-freezing, the time to uncover the shade net is in late November, and the time to uncover the shade net in dry years can be extended to late December.

Fertilization method of Luohansong

1. Luohansong needs proper fertilization when it is cultivated. When fertilizing, it should be noted that Luo Hansong does not like thick fertilizer, so it should not be too thick fertilizer when breeding. During its growing season, some mature organic fertilizers can be used. Generally, the fertilizer is applied once every 15 days, and water can be irrigated on the second day after applying fertilizer, which can promote the absorption of fertilizer by the root and dilute the fertilizer.

2. If it is planted in the ground, the Pinus elliottii can be fertilized once when the spring and autumn shoots grow, and there is no need to apply fertilizer at other times. When applying fertilizer, you can dig a ditch to apply fertilizer, and water should be irrigated the next day.

3. In order to make the leaves of Luohansong green and ornamental, no matter it is potted or planted on the ground, fertilizer and water can be used every half a month. Add a small amount of fertilizer to the water and supervise it.

The watering method of Luohansong

1. First of all, potted Luohansong needs to have a certain ability of drainage, be careful not to accumulate water for a long time, otherwise it will lead to its rotten roots. When watering Luohansong, you need to keep the soil slightly dry, which is what flower friends say is three percent wet and seven percent dry. Follow the principle that you'd rather be dry than wet, and don't overwater it when watering.

Secondly, in summer, because of the high temperature and strong light in summer, evaporation will be very exuberant, so it is necessary to water more and the soil should not be too dry to prevent the leaves from withering and yellowing.

How to graft Luo Han Song

1. Twig grafting. Most of the tender branch grafting uses the big leaf Luohan pine as the rootstock, it should be noted that the rootstock needs to be pruned properly before grafting, and then the tender shoots of Siraitia grosvenorii can be selected as the scion for grafting, and the cutting method is the same as other grafting. When grafting, the scion should be aligned with the cambium of the rootstock, and then it should be managed properly so that the plant can grow healthily. It has been proved scientifically that this kind of grafting method has the highest survival rate.

2. Abdominal connection. The rootstock selected by the ventral grafting method of Luohansong is also big-leaf Siraitia grossedentata, but it takes two to three years old. It can also be used as a scion and can be carried out all the year round. The difference is that the grafting site becomes the abdomen of the rootstock. No matter which kind of grafting method should be bagged and moisturized. Of course, if grafting is to be carried out in the middle of summer and cold winter, we should pay great attention to the management problems in order to avoid plant death.

3. High branch grafting. The high branch grafting method of Siraitia grosvenorii also uses the big leaf pine as the rootstock and the rice leaf pine as the scion, but the survival rate of this grafting method is low, so it is generally not used.

There are many methods of propagation of Pinus elliottii, which are generally based on sowing and cutting. you can choose one you like when you breed. The maintenance after reproduction is related to its growth and survival rate, so the management of watering and fertilization also needs to be strengthened.
