液体地膜对番茄幼苗生长的影响

Effect of liquid mulch film on tomato seedling growth

喷施适量的液体地膜,能够达到节水的效果,并且有利于植物的生长。本试验在番茄育苗基质中,分别添加剂量1、2、3和4 L·m^(-2)的液体地膜,以期探索液体地膜对番茄幼苗生长发育的影响,筛选适宜的液体地膜施加量,培育番茄壮苗。研究结果发现,基质中添加液体地膜可以显著提升番茄幼苗地上、地下部干鲜重及全株干鲜重、壮苗指数、根系活力;显著增加番茄叶片的叶绿素含量和光合速率。液体地膜施用量为3 L·m^(-2)时各项指标综合表现最优。

Spraying an appropriate amount of liquid mulch film can achieve the effect of water saving and be conducive to plants growth.This experiment added liquid mulch film with amounts of 1,2,3 and 4 L·m^(-2)to the tomato seedling substrate,respectively,in order to explore the effect of liquid mulch film on the growth and development of tomato seedlings,screen the appropriate liquid mulching film application amount,and cultivate tomato seedlings.The results showed that the addition of liquid mulch film to the matrix could significantly improve the dry and fresh weight of tomato seedlings aboveground and underground,the dry and fresh weight,seedling index and root viability of whole plants,and significantly increased the chlorophyll content and photosynthetic rate of tomato leaves.And the comprehensive performance of various indicators was optimal when the liquid mulching film application amount was 3 L·m^(-2).
