茶树木是深根性作物，但杆插苗的根系一般只是向水平方向发展而很少向垂直方向仲育，以致在遇到气象灾害时往往导致生育不良。为诱导扦插苗的根系向垂直方向发展，日本宫崎县综合农业试验场茶业支场特用纸钵杆插育苗的方法进行了试验。试验结果表明，纸钵育苗与常规育苗法相比 Tea trees are deep-rooted crops, but the root system of stems is usually horizontally oriented and seldom subdued vertically, often resulting in poor fertility in the event of a meteorological disaster. In order to induce the root system of cutting seedlings to develop in the vertical direction, experiments were carried out on the method of inserting the seedlings with special paper-cup stems in the branch of tea industry in Miyazaki Prefecture, Japan. The test results show that compared with the conventional nursery seedling raising
