木酢液对几种类型蔬菜生长调节效应的影响

大棚种植了西红柿、辣椒、大白菜、黄瓜和萝卜等6种4类蔬菜。苗期时，喷施木酢液1000倍液；定植后，采用喷施200倍液、300倍液、400倍液、500倍液、600倍液等5个浓度处理，以此来分析施用木酢液对各类蔬菜产量、根长及株高的影响。结果表明：木酢液对不同类型的蔬菜都有一定的增产作用，但效果不一，300倍液适用面较广、200倍液对不同类型蔬菜都有生理毒害效应、600倍液对蔬菜的生长长势有明显的促进作用。总体看来，适宜浓度的木酢液能促进植株生长，提高蔬菜产量。

Effects of Wood Vinegar on the Growth of Vegetables in Several Types

Tomatoes,peppers,cabbages,cucumbers and radishes were planted in the greenhouse.This protected ground experiment was conducted to study the effects of wood vinegar on output,root length and plant height of vegetables.The experiments sprayed P1000 （diluted wood vinegar 1000 times） in seedling stage and P200 、 P300 、 P400 、 P500 、 P600 in field planting stage.Results showed that the application of wood vinegar increased production spotty and P300 could be used in 2 types of vegetables.P200 evidently poisoned vegetables of different types.P600 promoted the growth of roots and stems significantly.In general,wood vinegar with proper concentration can raise the production and be suitable for vegetable growth.
