本研究用尿素喷施在叶面上促进茶芽生长改善质量不好的夏茶,对喷施浓度和次数,喷施始期和间隔作了研讨。从一芽二叶期起,每10公亩(折合1.5市亩—译注)隔日用0.8—1%的尿素溶液200—300升施3—4次。在首次喷施后的4—5天,叶子颜色变得鲜绿,第三次喷施后5—7天进入采摘期,茶芽伸育良好,叶质柔软,叶色
In this study, urea was sprayed on the foliage to promote the growth of tea buds to improve the quality of summer tea, spraying concentration and frequency of spray initiation and interval were discussed. From the buds of the second leaf period, every 10 acres (equivalent to 1.5 mu per person - Annotation) every other day with 0.8-1% urea solution 200-300 liters 3-4 times. In the first 4-5 days after spraying, the leaves become bright green color, 5-7 days after the third spray into the picking period, good elongation tea buds, leaves soft, leaf color
