以黄瓜、番茄、茄子、辣椒幼苗为试材,研究了不同浓度羧甲基壳聚糖对各种类蔬菜苗期生长指标的影响。结果表明:不同浓度羧甲基壳聚糖对同种蔬菜苗期生长指标影响不同,适宜浓度的羧甲基壳聚糖能明显提高各种蔬菜的各项生长指标,在一定浓度范围内,随着浓度增大,效果越明显,促进作用越强,且在0.1g/L浓度处理时表现最好;当大于0.1g/L浓度时,促进作用随之降低,但均高于对照。
The cucumber, tomato, eggplant and pepper seedlings were used as materials to study the effects of different concentrations of carboxymethyl chitosan on the growth indexes of various vegetables at seedling stage. The results showed that: different concentrations of carboxymethyl chitosan on the growth of the same vegetable seedling indicators of different concentrations of carboxymethyl chitosan can significantly improve the growth of various vegetables indicators, within a certain concentration range, with With the increase of concentration, the effect is more obvious, the stronger the promotion effect, and the best performance when the concentration of 0.1g / L; when the concentration is greater than 0.1g / L, the promotion effect decreases, but were higher than the control.
