80年7月在“茶”上刊载并讨论了我们关于有机体(植被)覆盖物对增进土壤肥力和提高茶树对磷的吸收的三个不同试验。“土壤肥力恢复”试验是按下列方式设计的1.清耕法;2.化学除草;3.生草法(禾本科昼眉草);4.黑色薄膜覆盖。这项试验开始于71年用6/8无性系按1.21×1.21米672株/公顷植于表土严重流失的
In July 1980, we published and discussed in our tea three different experiments on the coverage of organisms (vegetation) to improve soil fertility and increase the phosphorus uptake by tea trees. “Soil Fertility Restoration” test is designed in the following manner 1. Tillage; 2. Chemical weeding; 3. Lawn grass (grass Cerambycidae); 4. Black film covered. The test began in 71 years with 6/8 clones by 1.21 × 1.21 m 672 plants / hectare planted in the soil surface of serious loss
