海藻提取物(海藻肥)在蔬菜上的应用效果研究

The effect of seaweed extract on vegetables

通过对海藻提取物在蔬菜上的应用效果研究，结果表明：海藻提取物可提早蔬菜的采收期6-14d，前期产量提高10．8％-27．4％，总产量提高6．8％-19．2％，并明显改善品质；以2．0g／L的海藻提取物处理日光温室番茄植株，可使番茄最大节水率达到22．6％；用不同浓度的海藻提取物处理菠菜叶片，可降低菠菜硝酸盐含量66．3％-93．2％；以2．0g／L的海藻提取物对辣椒进行灌根处理，可使辣椒生育期施用化肥量节约20％。

According to the study of seaweed extract on vegetables, results indicated that seaweed extract could bring harvest time forward 6 ～ 14 days, enhance early output by 10.8% ～ 27.4%, total output by 6.8% ～ 19.2%, and dramatically improve quality. When the plant of tomato was treated by 2.0 g/L seaweed extract in solar greenhouse, its water - saving rate reached 22.6 %. Using different concentrations of seaweed extract to treat spinach leaves, could be depressed nitrate by 66.3% ～ 93.2%. Using 2.0 g/L seaweed extract to irrigate root of hot pepper, could be saved chemical fertilizer by 20 % in the whole growth period of hot pepper.
