茶区多分布于红黄壤山地及丘陵地区,保持水土是垦植新茶园中的一个重要环节,我场于1957—1963年的研究结果是:1.在红壤丘陵地垦植茶园,不采取水土保持措施,新垦植三年合计每亩土壤冲刷量:5度的坡地茶园为19661斤(第一年9962斤,第二年6411斤,第三年3288斤),20度的坡地茶 Tea areas are distributed in the mountainous and hilly areas of red-yellow soil. Maintaining soil and water is an important part of cultivating new tea gardens. The results of my study in 1957-1963 are as follows: 1. Cultivating tea gardens in red soil hilly areas, Measures to maintain the new reclamation for three years Total amount of soil erosion per acre: 5 degrees slope tea garden 19661 pounds (9962 pounds the first year, 6411 pounds the second year, third year 3288 pounds), 20 degrees of slope tea
