本文研究了红壤成年条栽茶园免(少)耕的技术效应。八年的试验结果表明,茶园土壤免(少)耕能增加茶叶产量,降低生产成本,并具有很好的生物效应。免耕与常规耕作比较,平均增产10.2％,纯收入增加15.98％;在100×20×60cm~3土体内的茶树根系总量(含吸收根、输导报)多1.2倍,其中吸收根多1.8倍,有利于茶树水肥的吸收。免耕还具有较好的水热效应,土壤微生物数量明显增加;水土保持能力加强,土壤冲刷量仅为常现耕作的17.3％。
In this paper, we studied the technical effects of free (or less) tillage cultivation of red cultivated adult tea plantations. Eight years of trial results show that the tea plantation soil free (less) plowing can increase tea production, reduce production costs, and has a good biological effect. Compared with conventional tillage, no-tillage increased yield by 10.2% on average and net income increased by 15.98%. The total amount of root system (including absorbed root and hyacinth) in tea plantations of 100 × 20 × 60cm ~ 3 was 1.2 times more than that of conventional tillage, Times, is conducive to the absorption of tea fertilizer. No-tillage also had better hydrothermal effect, and the number of soil microbes increased obviously. Soil and water conservation capacity was strengthened, and the amount of soil erosion was only 17.3% of that of conventional farming.
