断里兰卡茶叶研究所对株龄3.5月的茶树TR12025无性系作了温室试验。就光照(无荫蔽和荫蔽)、土壤水分(保持在40%和20%)和施氮(每100株1.55克或6.20克)三个项目作两种不同处理的对比。试验结果表明,不同处理对茶树的生长和顶端优势有相互作用。两种氮肥用量对生长均无差异。荫蔽和控制水分 Railanka Tea Research Institute conducted a greenhouse experiment on tea plant TR12025 clones with a plant age of 3.5 months. Three different treatments were compared for light (no shading and shading), soil moisture (kept at 40% and 20%) and nitrogen application (1.55 or 6.20 grams per 100 plants). The experimental results show that the different treatments have an interaction on the growth and the top superiority of tea tree. There was no difference in growth between the two nitrogen rates.
