摘要
采用1.20、1.70和2.20mL/L的海绿素对苋菜进行叶面喷施,研究海绿素对苋菜抗逆性及品质的影响。结果表明:适宜浓度的海绿素可促进苋菜的生长,提高叶绿素含量,氨基酸含量及其抗逆性,增加了苋菜产量,但有减低其品质的趋势。在不同的生长发育期,其作用效应有所不同。以1.70mL/L的海绿素处理效果较好。
The effects Of Bio-20 seaweed fertilizer on Amaranthus mangostanus L. by spraying 1.20,1.70 and 2. 20 mL/L were studied. The resUits showed that appropriate concentration of Bio-20 seaweed fertilizer could enhance the growth, improv the eontenf of chlorophyll and aminophenol, increase production and improve stress resistance of amaranth. But the quality had a trend of decrease. However the effect was different during different growth and development stage. Treatment of 1. 70 mL/L Bio-20 seaweed fertilizer had the best effect.
