Cultivation Technique of Seedling Used for Raw Material of Fetal Tea

Abstract

Fetal tea is a new type of tea made from seedling before its big euphylla come into leaf. So the yield and quality of seedling used for raw material of fetal tea directly affect the fetal tea yield and quality; the main purpose of this paper is to explore the effect of full light, half light and dark conditions on the growth of seedling used for raw material of fetal tea, and to provide a reference basis for the production of seedling with high quality. The tea tree seeds were cultivated with water under full light, half light and dark conditions, respectively; Then quadrats were set to observed regularly germination state of seed, growth of baconic and germ, meanwhile growth of root, stem, leaf, euphylla of “germ seedling”; By comparing the difference between different illumination conditions, the appropriate light conditions were selected as follows. The number and speed of seed crack were 27.0% and 63.4% higher under full light than under dark conditions and half light, respectively; Meanwhile the number of seed crack was 28.6% higher under dark conditions than under half light. As a result, the full light was the best for cultivating seedling used for fetal tea, dark condition was middle, and half light was worst. The baconic elongation of seed were 87.7% and 93.7% higher under full light than half light and dark condition, respectively, while 3.1% higher under half light than dark condition; therefore, full light was the best condition to promote baconic growth, half light was second, dark condition was the worst. The growth length of germ were 76.0% and 92.0% lower under half light and under dark condition than under full light, respectively, while 66.6% lower under dark condition than under half light, hence, full light was the best condition to promote germ growth, half light was second, and dark condition is the worst. Based on above results, it was concluded that cultivating tea seed with water under full light can obtain higher output of seedling used for raw material of fetal tea.
