松树芽苗直接上山造林,具有降低造林成本,减轻劳动强度,免去育苗程序,确保造林成活率和提高林木生长量的优点,是值得推广的植树造林新技术。现集各地经验,介绍其技术要点。 一、催育芽苗 种子用0.1％的高锰酸钾或0.2％的硫酸铜溶液浸30分钟,捞起用清水冲净种子表面的药液,置于50℃的温水中浸24小时,再放在垫盖草袋的箩筐中,每天用40℃的温水喷洒催芽,次数以保持种子间温度在20
It is worth promoting the new afforestation technology that the pine shoots directly afforestation in the mountains, with the advantages of reducing the cost of afforestation, reducing the labor intensity, eliminating the nursery procedures, ensuring afforestation survival rate and increasing the growth of trees. Now set all over the experience, introduce its technical points. First, germination sprout seedlings with 0.1% potassium permanganate or 0.2% copper sulfate solution soak for 30 minutes, picked up with water rinse the surface of the seed liquid, immersed in warm water at 50 ℃ for 24 hours, and then put In the mat covered straw basket, every day with 40 ℃ warm sprinkler sprouting, the number of times to maintain the temperature between seeds 20
