摘要:
以海带渣为原料，采用酶解方法制备海带渣提取物（KWE）作为海藻叶面肥，在大田试验中研究稀释不同倍数（10、30、50倍，分别简称KWE10、KWE30和KWE50）的KWE喷施对彩椒和茭白的生长发育、营养特性的影响，发现KWE对彩椒和茭白的生长有显著的促进作用。与未喷施KWE的对照相比，KWE10、KWE30、KWE50处理的彩椒株高增长量比对照分别提高14.77%、11.92%和8.38%，彩椒叶片增长量分别提高9.60%、33.90%和26.71%，彩椒单果质量分别增加18.28%、10.08%和7.93%。喷施KWE对彩椒各品质指标有明显改善作用。KWE10处理对提高彩椒维生素C含量和降低硝酸盐含量效果最佳，维生素C含量比对照提高24.70%，硝酸盐含量降低28.16%。此外，KWE喷施后，彩椒可溶性糖含量显著提高93.7%～128.0%，可溶性蛋白质含量提高25.78%～30.73%。KWE10处理和KWE30处理可提高茭白株高增长量7～9 cm，在分蘖期平均增加1～2个分蘖，但对叶面积无显著效果。喷施试验浓度的KWE对茭白品质的改善不显著。
Abstract:
Kelp waste extracts (KWE) were generated by enzymolysis and were applied as foliar fertilizer in field experiments to study the effects of KWE on the growth and quality of color pepper and water bamboo in this work. KWE was diluted by 10 times, 30 times and 50 times (KWE10, KWE30 and KWE50) and sprayed on color pepper and water bamboo. Results showed that KWE could significantly improve the plant growth of both color pepper and water bamboo. Compared with the control group, the plant height increment of color pepper was promoted by 14.77%, 11.92% and 8.38%, the increment of leaves was increased by 9.60%, 33.90% and 26.71%, and the single fruit weight was improved by 18.28%, 10.08% and 7.93% under treatments of KWE10, KWE30 and KWE50 respectively. The treatment of spraying KWE could significantly improve the quality of color pepper. KWE10 showed the optimal effect on increasing vitamin C content and reducing the nitrate content, with an increase of 24.70% in vitamin C content and a decrement of 28.16% in nitrate content, compared with the control. In addition, the soluble sugar content of color pepper exhibited an increase of 93.7%-128.0%, and the soluble protein content showed an enhancement of 25.78%-30.73% under KWE treatments. There was an elevation in the plant height increment of water bamboo by 7-9 cm and a increase in the tiller number by 1-2 at tillering stage under treatments of KWE10 and KWE30, while there was no significant effect on leaf area. The quality of water bamboo was not improved greatly under treatments with tested concentration of KWE.
