喷施槲皮素对惠水县国储林下发展林下种植作物的影响分析

Analysis of the Influence of Quercetin Spraying on the Development of Crops under National Reserve Forest in Huishui County

分析喷施槲皮素对惠水县国储林下发展林下种植作物的影响,旨在为惠水县国储林及林下经济的进一步发展提供借鉴和参考。本研究在惠水县国储林项目示范基地进行,对林下作物喷施槲皮素,分析喷施槲皮素对林下南板蓝根以及林下羊肚菌种植作物的影响。结果证实,喷施槲皮素可促进国储林林下南板蓝根作物的生长,Z3处理的南板蓝根株高较CK处理增加10.27%,分枝条数较CK处理增加25%;Z1、Z2和Z3处理的林下南板蓝根作物的叶片总数较CK处理呈递增趋势;喷施槲皮素可促进国储林林下羊肚菌作物的生长,各个处理的氨基酸、蛋白质、粗多糖、脂肪排序为:T2>T3>T1>CK;T2处理的DPPH自由基清除率、ABTS自由基清除率、羟自由基清除率高于其他处理,整体而言,T2处理下的羊肚菌作物抗氧化性更强。因此得出,喷施槲皮素对惠水县国储林下发展林下种植作物均有不同程度的影响,喷施900μmol/L槲皮素促进南板蓝根作物生长,喷施600μmol/L槲皮素促进羊肚菌作物的生长,具体喷施剂量需结合林下种植作物的类型合理选择。

This study aims to analyze the impact of spraying quercetin on the development of under-forest crops in the Guochu Forest of Huishui County,providing a reference for the further development of the Guochu Forest and under-forest economy in Huishui County.The study was conducted at the demonstration base of the Guochu Forest project in Huishui County,where quercetin was sprayed on under-forest crops to analyze the impact of spraying quercetin on the growth of under-forest Radix Isatidis and under-forest Morchella crops.The results confirmed that spraying quercetin can promote the growth of Radix Isatidis crops under the Guochu Forest,with the height of Radix Isatidis plants in the Z3 treatment increasing by 10.27%compared to the CK treatment,and the number of branches increasing by 25%compared to the CK treatment.The total number of leaves in the Radix Isatidis crops under the Z1,Z2,and Z3 treatments showed an increasing trend compared to the CK treatment.The order of amino acids,proteins,crude polysaccharides,and fats for each treatment was T2>T3>T1>CK.The DPPH free radical scavenging rate,ABTS free radical scavenging rate,and hydroxyl radical scavenging rate of the T2 treatment were higher than those of other treatments.Overall,the antioxidant capacity of the Morchella crops under the T2 treatment was stronger.Therefore,it was concluded that spraying quercetin had varying degrees of impact on the development of under-forest crops under the Guochu Forest in Huishui County.Spraying 900μmol/L quercetin promoted the growth of Radix Isatidis crops,and spraying 600μmol/L quercetin promoted the growth of Morchella crops.The specific spraying dose needs to be reasonably selected based on the type of crops planted under the forest.
