Experiment of Different Soaking Seed Seedling Techniques of Castanopsis Hystrix Seed
To cultivate the Castanopsis hystrix seed ,the experiment adopts different ways of water soaking and abt3 rooting powder solution soaking after disinfection with 0 .3% potassium permanganate solution . The nutrient soil is made up with 7 kinds of raw materials in different configurations ,including red soil ,fire clay ,clay paddy soil ,rice husk ,poultry manure ,cattle feces ,calcium ,magnesium ,phosphorus .After a certain time ,a light matrix nutrient soil forms and container seedling technology test begins .The results show that the average seedling germination rate of the seed soaked by ABT3 rooting pow der solution is 4 .1% higher than that soaked by water .For 1a seedling which is cultivated in light media container ,the application of abt3 rooting powder solution soaking seedling growth of seedling the average growth of height ,diameter ,crown width of the seed soaked by ABT3 rooting powder solution is respectively 11 .23% ,12 .50% and 6 .12% lar‐ger that soaked w ater .
