一、目的要求:我国大部茶区采茶季节往往久旱不雨,茶园土壤在長期裸露情况下,土壤水分不断散失;茶园又多处在高山地区,引水灌溉不便,因而显著影响茶叶产量。为此,于1957年——1958年兩年进行土壤复盖试驗,探討茶园复盖、以及复盖时間長短、复盖物种类等对于土壤理化性狀、茶树生長、产量的影响等,为进一步推行茶园复盖提供依据。二、試驗方法: 本項試驗的处理有: 1.种植绿肥作物为复盖物:以矮生胡枝子、匍匐性綠肥作物为代表。
First, the purpose and requirements: Most of China’s tea season is often a long drought in the tea harvest, the tea garden soil in the long-term nudity, the continuous loss of soil moisture; tea plantations and more in alpine areas, diversion irrigation inconvenience, which significantly affected the yield of tea. Therefore, in the two years from 1957 to 1958, soil cover experiments were conducted to investigate the effects of covering of tea plantations, covering time and covering types on soil physical and chemical properties, tea tree growth and yield, etc. To further promote the provision of tea grounds. Second, the test method: The treatment of this test are: 1. Planting green manure crops for the cover: dwarf Lespedeza, creeping green manure crops as the representative.
