茶树不同的播种密度,对茶子出苗、幼苗越夏、生育和成活率具有影响,但不同的播种方式,在播种当年却看不出明显差异。各种播种密度的出苗率和齐苗速度反映出密度愈小,出苗率愈低,从始苗到齐苗所需的时间也愈长。随着播种密度的增加,出苗率和齐苗速度有逐渐增高和显著加快的趋势。 Different sowing densities of tea tree have an impact on the emergence of tea seedlings, the summer, birth and survival rate of seedlings, but different sowing methods can not see obvious difference in sowing year. The germination rate and the rate of seedling emergence of various planting densities reflect the smaller density, the lower the emergence rate, and the longer the time from starting to seedling emergence. With the increase of sowing density, the emergence rate and seedling emergence rate increased gradually and significantly accelerated.
