在我省红壤丘陵地区,一般春茶占全年50—55％,品质好,经济价值高,因此如何提高春茶产量和品质,对于完成全年产量和产值指标,具有十分重要的现实意义。鉴于碳铵性质不稳定,吸湿性强,极易挥发,在春季追施采用一般方法,挥发损失较大,进行深施,又有碍于茶树根系的发展,加之春雨连绵,易于流失,春茶吸收较少,据报导一般对春茶产量只有5—7％增产效果。为了探求形成春茶的物质基础和冬施碳铵对翌春
In the red soil hilly region of our province, the general spring tea accounts for 50-55% of the whole year, with good quality and high economic value. Therefore, it is of great practical significance to complete the annual output and output value index in order to improve the yield and quality of spring tea. In view of the unstable nature of ammonium bicarbonate, hygroscopicity, highly volatile, topdressing in the spring using the general method, volatile loss greater depth of implementation, but also hindered the development of tea tree roots, combined with spring rain, easy to drain, spring tea Less absorption, it is reported that the yield of spring tea is generally only 5-7% yield effect. In order to explore the material basis for the formation of spring tea and winter ammonium bicarbonate on the next spring
