When do tea plant flowers bloom?
This article introduces the blooming time of tea plant flowers and simple introduction of tea plant flowering maintenance experience, the specific contents are as follows:
The ecological construction mode of tea garden covers the fields of tea varieties, cultivation, soil, biology, plant protection, and fertilization. Adhering to the rational ecological ethics thought centered on humans, and striving for the revival of the tea industry.
The flower is the reproductive organ of the tea plant, and the flowering habits and flower yield of the tea plant are the manifestation of the plant's nature. Investigating the flowering habits and flowering amount of tea plants is of great significance for studying the genetic characteristics of tea plant traits, guiding the classification of tea plant germplasm resources and hybrid breeding, improving tea yield, and the efficient use of tea plant flower resources.
Tea plant flowering habits
Tea plant flower buds begin to differentiate in June and continue to occur every month, generally lasting until November, or even the following spring. The later it is postponed, the lower the flowering and fruiting rate. Flowers and fruiting rate are higher in summer and early autumn. The first round of new shoot flower bud differentiation occurs around June, the second, third, and fourth rounds of new shoot flower bud differentiation periods are in late July, late August, and mid-October respectively. The flowering period of tea plants varies significantly due to differences in planting areas, tea plant varieties (germplasm), and interannual (meteorological factors).

1. Full flowering period
The full flowering period of tea plants from different origins varies. The flowering period of Japanese tea plants is from September to November. The flowering period of most tea-growing areas in China is from September to December, while in Yunnan Xishuangbanna and Hainan, tea plants bloom every month. In Hangzhou, the flowering period of tea plants is from mid-August to the end of December, with a full flowering period of 120 days. In Fuan, Fujian, the flowering period is from mid-September to mid-February of the following year, with a full flowering period of 153 days.
For the same variety, the length of the full flowering period varies from place to place. Fuding Dabaicha has a full flowering period of 46-90 days in Hangzhou and 138 days in Fuan, Fujian. This indicates that in low latitude warm areas, the full flowering period of tea plants is longer. The differences in the length of the full flowering period of different years and different tea plant varieties reach significant and highly significant levels. Zhao Xueren and others have conducted a continuous survey for 5 years, and the results show that the full flowering period of Fujian Xianren is 31-61 days, with an average of 48 days, Fuding Dabaicha is 46-90 days, with an average of 69 days, and Ziyu variety is 108-120 days, with an average of 113 days.

2. Beginning and end of flowering period
The difference in the beginning of the flowering period between varieties and years reaches a highly significant level. The difference between varieties in the end of flowering period reaches a significant level, but the difference between years does not reach a significant level. In Hangzhou, the temperature in January is low (average monthly temperature of 3.5℃), and the end of flowering period of tea plants is mostly in mid-December. In Fuan, Fujian, the temperature in January is higher (>8℃), and the end of flowering period of tea plants is mostly in early February of the following year. This indicates that the beginning of the flowering period of tea plants is obviously affected by varieties and meteorological factors, while the difference between varieties in the end of flowering period is less significant but more affected by temperature.
The difference in the length of the full flowering period, the beginning, end, and peak flowering period between individual plants (F1) of the tea plant's seedlings is significant, with an obvious separation phenomenon. Different populations of tea plants were investigated for the beginning of flowering by Daishi Chen, and the results show that the beginning of flowering for Japanese local species is September 28th, for the seedlings of Sabei (F1) is September 25th, for the Chinese species (local species in the Yangtze River Valley) is October 3rd, for the Taiwan species is October 23rd, and for the Indian hybrid is October 7th. There is a similar trend between the germination period of the spring shoots and the beginning of flowering, with the Japanese local species flowering earliest, followed by the Chinese species, and the Indian species flowering later. The survey results of Guo Yuanchao and others show that the variety from the tea-growing area in Jiangnan, Longjing, has an earlier flowering period, the variety from the tea-growing area in Southwest Yunnan Dayeicha has a later flowering period, and the variety from the tea-growing area in South China, Fuding Dabaicha, is between the two.

3. Peak flowering period
The peak flowering period of most tea-growing areas in China is from mid-to-late October to mid-to-late November, while in Yunnan Xishuangbanna and Hainan, it is from December to January of the following year. The results of a 5-year continuous survey of the peak flowering period of three varieties, including Fujian Xianren, by Zhao Xueren show that the peak flowering period of Fujian Xianren is 10-19 days, with an average of 15 days; Fuding Dabaicha is 21-31 days, with an average of 24 days; Ziyu variety is 26-43 days, with an average of 35 days. In Fuan, Fujian, the peak flowering period of tea plants can last for 50-80 days.
In the same region, the difference in the start and end dates of the peak flowering period and the number of days of peak flowering between varieties reaches a highly significant level, the difference in the start and end dates of the peak flowering period between years reaches a significant level, but the difference in the number of days of peak flowering between years does not reach a significant level.
