摘要
为筛选适合茶树(Camellia sinensis)施用的叶面肥,以福鼎大白茶为材料,采用随机区组设计,以清水(CK_1)和尿素(CK_2)为对照,研究丰声、农盛、丰瑞达、纪高和绿佼5种叶面肥对夏茶新稍生长及产量的影响。结果表明:与CK_1和CK_2相比,喷施这5类叶面肥均一定程度地促进夏茶新梢生长,尤其是喷施绿佼的新稍萌发量多、单位面积产量高、一芽2叶百芽重高和长势快,平均分别比CK_1和CK_2增加58.11%和29.92%、142.34%和50.25%、26.14%和14.63%、84.99%和32.43%。绿佼是适合茶树施用的叶面肥。
The effects of five foliage fertilizers （Fengsheng, Nongsheng, Fengruida, Jigao and Lvjiao） on new shoot growth and yield of Fudingdabaicha were studied by using a randomized block design and taking water and urea treatment as CK1 and CK2 to screen the optimum foliage fertilizer for Camellia sinensis in Summer. Results： Five tested foliage fertilizers all can promote new shoot growth to a certain extent compared with CK1 and CK2. The new shoot germination amount, yield per unit area, 100-bud weight and growth vigor of Fudingdabaicha with two leaves and a bud sprayed with Lvjiao foliage fertilizer are 58.11 % and 29.92 %, 142.34 % and 50.25 %, 26.14% and 14.63%, and 84.99%and 32.43 % higher than CK1 and CK2 respectively. In conclusion, Lvjiao foliage fertilizer is the optimum foliage fertilizer for Camellia sinensis in Summer.
