不同工厂化穴盘育苗条件对茶苗生长影响研究
Study on the Effect of Industrialized Hole Plate Seedling Cultivation of Tea Trees under Different Conditions on the Growth of Tea Seedlings
摘要
Abstract
This experiment studied the effects of cutting substrate,growth regulator concentration,plug tray size,cut-ting leaf retention and cutting lignification degree on the survival rate,new shoot length,stem diameter and leaf number of tea seedlings grown under industrialized seedling cultivation conditions.The results show that the use of light substrates such as peat moss,perlite and vermiculite could significantly improve the survival rate of cuttings.The survival rate,new shoot length,stem diameter,and leaf number of tea seedlings grown in a mixed substrate of perlite:peat moss(2∶35)were all higher,and the survival rate and new shoot length were significantly higher than other treatments.Using ABT1 growth regulator to treat the cuttings with a slow immersion treatment for 0.5 hours could improve the survival rate,new shoot length,and stem diameter of tea seedlings grown in plug trays.The plug tray size had little effect on the survival rate,new shoot length,stem diameter,and leaf number of tea seedlings,but it had a significant impact on the number of viable tea seedlings per square meter.The number of viable tea seed-lings per square meter of the 128-hole plug tray was significantly higher than other treatments.The number of leaves retained on the cutting had little effect on the survival rate,stem diameter,and leaf number of tea seedlings,but it had a significant impact on the new shoot length of tea seedlings.It was better to retain all leaves or 1/2 leaves.Different lignification degrees of cuttings had little effect on the survival rate,new shoot length,and leaf number of tea seedlings,but they had a significant impact on the stem diameter of tea seedlings.Therefore,green stems or semi-lignified stems were preferred.关键词
