Problems solved by technology

[0002] The cultivation of cedar in the introduction area of ​​my country shows that the flowering period does not meet, and most of them cannot be pollinated naturally. It is easy to get blight and other diseases, which has caused great economic losses to seedling farmers.

Embodiment 1

[0020] 1) Preliminary preparation: Site selection and construction of nursery greenhouses. The nursery soil is sandy loam soil below 50cm and fully decomposed circle manure, and mixed with an appropriate amount of ferrous sulfate. After fully mixing, the nutrient soil is prepared with a pH value of 5.5; seedling cultivation The size of the bag is 8cm*13cm, and 6 seepage holes are left at the bottom and around it, and it is filled with seedling soil and compacted to 80% full for later use;

[0021] 2) Seed treatment: Soak the seeds in warm water at 30°C for 12 hours before sowing, then sterilize and soak the seeds with 0.5% potassium permanganate for 30 minutes, remove the seeds and rinse them with clean water to dry them, then mix the seeds with wet sand at a volume ratio of 1:3 Mix evenly, place in a seedling growing shed to accelerate germination, keep the temperature at 15°C, and sow when the seeds are white in 10 days;

[0022] 3) Sowing: adopt the method of staged sowing,...

Abstract

The invention discloses a method for fast raising cedar seedlings and relates to the technical field of plant propagation. Instead of the traditional way of seeding cedar in spring, a way of seeding with harvesting is used. Collected seeds are treated. Container bags are used to raise seedlings in a solar greenhouse specially built. The processes such as seedling management and nursery transplanting are performed then to achieve raising the cedar seedlings. The method is simple and is easy to operate. The cedar seeds are promoted to germinate in advance, germination rate of the seeds is increased, seedling raising speed is increased, the raising time is brought forward evidently, and accordingly incidence rate of damping off in cedar is reduced and survival rate of the cedar seedlings is increased.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for rapidly growing cedar seedlings. Background technique [0002] The cultivation of cedar in the introduction area of ​​my country shows that the flowering period does not meet, and most of them cannot be pollinated naturally. It is easy to get blight and other diseases, which has caused great economic losses to seedling farmers. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method for rapidly growing cedar seedlings. The method is simple and easy by adopting the method of harvesting and sowing in autumn, and carrying out a series of technical treatments on the seeds, greatly improving the germination rate of the seeds and accelerating the growth rate of seedlings. It is easy to popularize, and basically solves the technical problems of current cedar seedling cultivation. [00...
