Forest tree seed aseptic sowing and seedling raising method

Abstract

The invention discloses a forest tree seed aseptic sowing and seedling raising method which comprises the following steps of S1, screening out seeds for later use; S2, soaking and disinfecting the seeds with a disinfectant, and soaking the seeds with a 0.5%-1% copper sulfate solution for 2-4 hours; S3, soaking the seeds in a germinating agent; S4, storing the seeds in fine sand, diluting 50% carbendazim wettable powder by 800-1000 times to form pesticide liquid, and spraying the pesticide liquid to conduct disinfection; and S5, placing the fine sand in an environment with the temperature of 0-5 DEG C for 60-90 days at the initial stage, and placing the sand-mixed seeds in a greenhouse with the temperature of 25 DEG C and the humidity of 80% for germination acceleration in early spring of the next year. Compared with the prior art, the method has the advantages that the seeds are fully disinfected and prevented from diseases and insect pests; and the seed germination time is short, the germination rate is extremely high, special nursing is not needed, good application prospects are achieved, the sand pit permeability is good, seed rotting is avoided, the seed germination uniformity is high, seedling growth is strong, and the characteristics of fast seedling formation, short growth period and simple operation are achieved.

Description

technical field [0001] The invention belongs to the technical field of forest tree seedling cultivation, and more specifically relates to a method for aseptic sowing and seedling cultivation of forest tree seeds. Background technique [0002] The conventional method of sowing and raising seedlings of forest trees is to directly sow the seeds in the soil. Because there are many germs, underground pests and weeds in the soil, although physical and chemical methods are used to treat the soil, there are still many kinds of diseases, insect pests and weeds. Residues in the soil, the seeds sown in the soil are damaged by diseases and insect pests, etc. Most of the forest tree seeds have the habit of deep dormancy. The main reason is that the emergence rate of natural seeds is too low due to physiological post-ripening without proper temperature-changing treatment. For this reason, we introduce a kind of forest tree seed aseptic sowing seedling raising method. Contents of the inv...
