Analysis on the planting and Market Prospect of Greening seedlings

There are many kinds of green seedlings, and most of them can be planted by cutting and grafting. And in the process of breeding, watering is also a crucial link.

Storage method of scion of Greening seedlings

1. After scion cutting, proper storage must be carried out before grafting. The common method is to tie 25-100 scions into a bundle, wrap them with thick waterproof paper or plastic film, and put a small amount of clean wet peat in the packaging material. Sand should not be put, because the sand will stick to the scion and make the section uneven during the grafting operation. If the packaging material is very wet, it will also produce a large number of fungal damage to the buds at low temperature, so the scion is more vulnerable in very wet conditions than in very dry conditions. If the storage time is long, it needs to be checked every few weeks to prevent the scion from getting too wet or too dry, and if the bud expands, it needs to be grafted immediately, or transferred to a lower temperature storage environment.

two。 Polyethylene plastic is a good packaging material, packaging with this material does not need to use other humidifying materials, the humidity of the scion itself is enough to meet the needs. A small number of small scions can be easily stored in plastic bags, and attention should be paid to marking them clearly.

3. The storage temperature of seedling scion is very important, if it needs to be stored for 2-3 weeks, it is suitable to be stored at about 5 degrees; if it is stored for 1-3 months, it is suitable to be stored at about 0 degrees to keep the buds dormant. But some plants, such as apricots and sweet cherries, begin to sprout after about three months, even if they are stored at this temperature.

Key elements of watering green saplings

Water quality: the water in the pipe is often used because of its guaranteed quality, but the tap water contains chlorine for disinfection and needs to be shelved for a period of time before it can be used. In addition, the same water temperature as room temperature is the most basic requirement in management, but it is also difficult to control when water consumption is large. Rain Water, in addition to the initial part, because it does not contain a variety of other substances, can be said to be an ideal water for greening. In architectural design, if possible, Rain Water should actively promote the use of technology.

Watering method: artificial watering is mainly related to the operator's understanding of soil characteristics, especially the use of natural soil. The appropriate degree of artificial watering should be based on the soil surface without splashing, stagnant water and flow. However, if the watering intensity is reduced and the watering time is prolonged, the soil may not be infiltrated by water, so it is necessary to ask experienced staff to operate it as much as possible, or strictly in accordance with the requirements.

Water quantity: the amount of water irrigated varies according to the watering interval, soil water retention and air humidity, and the amount of water at one time should be controlled below the soil water holding capacity, usually between 10 and 201pm, so that a certain interval can be maintained.

Analysis on the Prospect of Greening Tree species planting Project

Benefit analysis: there are many tree species needed for urban greening, such as cedar and ginkgo in the north, camphor, magnolia and sweet-scented osmanthus in the south. Planting large green tree species has higher economic benefits. According to the current situation, a camphor tree with a certain thickness costs as little as a few hundred yuan, thousands of yuan, and more than thousands of yuan, tens of thousands of yuan. The price of Magnolia magnolia is higher, generally the price of 8-to 10-year-old trees is in the thousands of yuan.

Risk hint: the growth cycle of green tree species is long, and the market situation is constantly changing during the growth period, and the price of high-priced tree species is not necessarily high after a few years. Therefore, in order to reduce the risk, one tree species should not be planted, at least three or more species should be planted. Due to the long production cycle, short-term income can not be obtained, in places with less land, for families with poor economic conditions, large-scale planting has economic risks. There is a risk of small production scale. Now urban greening needs a large number of tree species of the same species, time is tight, often can not meet the needs of users, can not sell a good price.

Now decorating the city with green saplings has become a very popular means, not only in cities, but also many families have planted a lot of green saplings in the courtyard to decorate the courtyard, and now many green saplings have also cultivated fast-growing varieties, so the market prospect of green saplings is still very much to look forward to.
