Abstract:

Taking high-altitude Myrica rubra as the research subject，this study explored the effects of cultivation techniques，adjusting branch pruning timing，adjusting clean-up periods，adjusting top-dressing schedules，and unifying fertilization standards（collectively referred to as "three adjustments and one unification"），on the yield and fruit quality of high-altitude Myrica rubra. The results indicated that the "three adjustments and one unification" technology promoted excellent growth of inflorescences，flowers，and leaves during the flowering season of high-altitude Myrica rubra，while protecting branches and trunks from frost damage. Compared with traditional cultivation technology，adjusting "autumn and winter pruning" to "spring pruning in the following year" can significantly（p<0.05）increase the single fruit weight of Myrica rubra by 40.51% to 62.03%，significantly increase the soluble solid content by 2.95 to 4.45 percentage points，significantly increase yield by 222.54% to 319.72%，and significantly increase output value by 296.71% to 439.64%. The cultivation technology of "pruning at the beginning of spring + cleaning the garden at the end of autumn + top-dressing during the Qingming festival" had a significant effect on improving the contents such as total sugar，flavonoids，total phenols and vitamin C of high-altitude Myrica rubra fruits. Therefore，by adopting the "three adjustments and one unification" technology，it is basically possible to ensure a bountiful harvest of high-altitude Myrica rubra.

Key words: high-altitude Myrica rubra, "three adjustments and one unification" technology, fruit quality, bountiful harvest
