摘　　要：为探寻一种汝城白毛茶性价比较高的扦插育苗方法,通过探讨秋季不同扦插时间不同基质对汝城白毛茶在扦插后翌年5月至6月的存活和生长情况,研究秋季扦插时间段和扦插基质对汝城白毛茶扦插苗培育的影响。结果表明,在现有管理强度下,10月中旬在营养土中进行扦插育苗,能取得与本地黄红壤心土育苗相近的效果(10月中旬在黄红壤心土和营养土上的扦插苗在翌年6月中下旬的萌芽率分别为60.33%和59.00%);黄红壤心土扦插时间筛选试验表明,扦插时间对扦插苗成活率、萌芽率和地径存在极显著影响,对扦插苗苗高存在显著影响,因此结合正交试验结果可以推断,使用当年生半木质化饱满枝条于10月中旬在本地黄红壤心土进行扦插育苗能够取得较高的性价比。In order to explore a method of cutting seedling cultivation of Rucheng white tea with higher cost performance.The effect of different cutting time and cutting medium on the growth and survival of Rucheng white tea from May to June of the next year were studied.Under the current management level the results of orthogonal experiment showed that,the effect of cutting seedling growing in nutrient soil in mid-October w as similar to local yellow red soil(The germination rates of cuttings on yellow soil and nutritive soil in mid-October were 60.33%and 59.00%respectively in mid-late June of the following year).The screening experiment of cutting time in yellow red soil showed that cutting time had significant effects on the survival rate,germination rate and seedling diameter and had significant effects on the height of cutting seedling.Therefore,combined with the orthogonal experiment results.Therefore,combined with the orthogonal experiment results,it could be concluded that the use of semi-lignified full branches of the same year to cut seedlings in the local yellow red soil soil in mid-October could achieve a higher cost performance.
