采用黄土、河沙的两种基质5个处理、1个对照、重复3次，进行油茶扦插育苗试验。结果表明：100％河沙为扦插基质的扦插成活率为100％、生根率为82．22％，分别高出100％黄土（对照）15．38％、76．17％；其次是75％河沙＋25％黄土，成活率、生根率分别为95．6％、82．22％，高出100％黄土（对照）的10．50％、76．17％。从扦插成活生根情况分析：100％河沙、75％河沙＋25％黄土和50％河沙＋50％黄土这三种处理的扦插苗根系的平均根长分别为4．41cm、3．42cm、3．97 cm ，明显优于对照。5个处理的扦插平均成活率、平均生根率、平均根系的生长长度木与对照相比均有显著和极显著差异。在油茶扦插育苗过程中，若空气、基质湿度大，基质透气好，扦插成活率高，从本次试验已进一步证明：河沙的基质疏松，扦插成活率高，苗木生根快，且根系发达；纯黄土的基质土质板结，透气性差，不利于扦插成活与苗木的生长。
採用黃土、河沙的兩種基質5箇處理、1箇對照、重複3次，進行油茶扢插育苗試驗。結果錶明：100％河沙為扢插基質的扢插成活率為100％、生根率為82．22％，分彆高齣100％黃土（對照）15．38％、76．17％；其次是75％河沙＋25％黃土，成活率、生根率分彆為95．6％、82．22％，高齣100％黃土（對照）的10．50％、76．17％。從扢插成活生根情況分析：100％河沙、75％河沙＋25％黃土和50％河沙＋50％黃土這三種處理的扢插苗根繫的平均根長分彆為4．41cm、3．42cm、3．97 cm ，明顯優于對照。5箇處理的扢插平均成活率、平均生根率、平均根繫的生長長度木與對照相比均有顯著和極顯著差異。在油茶扢插育苗過程中，若空氣、基質濕度大，基質透氣好，扢插成活率高，從本次試驗已進一步證明：河沙的基質疏鬆，扢插成活率高，苗木生根快，且根繫髮達；純黃土的基質土質闆結，透氣性差，不利于扢插成活與苗木的生長。

In this paper ,the effects of diferent nursery substrate on survival rates of Camellia olei f era cutting rooting were studied .The nursery substrate by yellow soil and sand was divided into 5 experimen-tal groups ,1 control group(by 100% yellow soil) and repeated 3 times .The results are as follows :the survival and rooting rate of cuttings in the 100% sand was the highest ,it was 100% and 82 .22% respec-tively ,and higher than the 100% yellow soil (the control ) 15 .38% and 76 .17% ;and followed in 75%sand + 25% yellow soil ,it was respectively 95 .6% ,82 .22% ,and higher than the control 10 .50% and 76 .17% .To discuss from the cuttage survival and rooting :The average root length of cutting seedling by 100% sand ,75% sand + 25% yellow soil and 50% sand + 50% yellow soil handle were respectively 4 .41cm ,3 .42cm ,3 .97cm ,significantly better than the control .The average cutting survival rate ,roo-ting rate and root grow th length of cuttings by the five processing contrasted significantly and very signifi-cant differences with the control .In the process of Camelliaoleiferaraising steekling ,if it had high hu-midity of the air and the media ,and good permeability of the media ,the cutting survival rate is higher . From the experiment has been further proof :because of the sand media is porous ,the cutting survival rate is high ,with the roots quickly and well developed ;the other ,the soil harden and poor permeability of the yellow media ,is not conducive to the cutting survival rate and grow th of seedlings .
