作物根系不仅起着使其个体固定、支持在大地上,和养料、水分吸收器官的机能;而且是光合产物贮藏、流转的场所,和氮素化合物生产的场所;而茶树还包括成味成分等品质的物质生成的机能。因此,弄清根系的生育、分布状况,是探索根系机能的前提。其次,日本茶树百分之六十以上栽植在倾斜地。这部分茶园,不仅表层土随降雨而被侵蚀,而且,在大量降雨时,以肥土部为中心的下层土也被侵蚀极为显著。这种现象以新建的二、三年生茶园居多,以后减
Crop roots not only serve to immobilize individuals, support the function of nourishment and water-absorbing organs on the earth, but also serve as a storage and circulation place for photosynthetic products and a place where nitrogen compounds are produced. Tea plants also include flavor components The quality of the material generated by the function. Therefore, to understand the fertility of the root system, distribution, is to explore the root function of the premise. Second, more than 60 percent of Japanese tea trees are planted obliquely. This part of the tea plantation not only eroded the topsoil with rainfall, but also eroded the subsoil centered on the stubborn soil during heavy rains. This phenomenon with the new second and third year tea mostly, after the reduction
