用盆栽的四年生薮北种茶树,研究新梢生育期间的温度对茶树新梢生育的影响;茶树新梢展开度(指新梢成熟,形成驻芽—译注)的进行速度,从萌发期到采摘期的新梢生育天数,判明了新梢生育的最低温度、最适温度和有效积温。其研究结果归纳如下: 1.新梢展开度的进行速度:气温在25℃以内时,温度愈高展开速度愈快,25℃以上时,温度愈高,展开速度愈缓慢。各茶季的平均温度,头茶为16℃,二茶为21℃,三茶为27℃,在这种平均温度的情况下,各茶季新梢每天的展开速度均在11％左右。
Using potted four-year-old Pei-bei tea plantations, the effects of temperature during the growth period of young shoots on the shoot growth of tea trees were studied. The speed of developing new shoots of tea plants (referring to the maturation of new shoots and the formation of shoots and translants) The number of new shoots during the harvesting days, identified the minimum temperature of young shoots, the optimum temperature and effective accumulated temperature. The results of the study are summarized as follows: 1. The speed of shoot development: When the temperature is below 25 ℃, the higher the temperature, the faster the unfolding speed. When the temperature is above 25 ℃, the higher the temperature, the slower the unfolding speed. The average tea season, the first tea is 16 ℃, two tea is 21 ℃, three tea is 27 ℃, in this case the average temperature, each tea season shoots daily deployment speed is about 11%.
