短穗扦插因苗木根系浅和在移植过程中受到机械损伤,导致茶苗成活率降低。据观察,一般扦插茶苗的根系长度约在10—20厘米以下,根幅约10—14厘米。而在移植过程中,根长的切断率为22.14—27.98%,根幅的切断率为5.84—18.62%,茶园缺苗率(以小丛计算)一般在10%左右。一旦遇到天旱、高温气候或技术不当时,缺苗率常多达30%以上,这是当前扦插茶苗应用中存在的重要问题之一。为了提高茶苗移植成活率和苗木质
Short-spike cuttings due to seedling shallow roots and mechanical damage in the process of transplantation, resulting in reduced survival rate of tea seedlings. It is observed that the general cuttage root length of tea seedlings about 10-20 cm below the root width of about 10-14 cm. In the transplanting process, the root length cut-off rate was 22.14-27.98%, root cutting rate was 5.84-18.62%, lack of seedling rate of tea plantations (in order to small plexus) is generally about 10%. In the event of drought, high temperature or improper technology, lack of seedling rate often up to 30% or more, which is the current cuttings tea seedlings in the application of one of the important issues. In order to improve the seedling transplanting survival rate and seedling quality
