农用植物酵素对黄瓜促生效果评价OA

To study the application effect of agricultural plant enzymes in agricultural production,agricultural plant enzymes were prepared using waste materials such as apple peels,banana peels,melons and cucumbers,and the promoting effect of agricultural plant enzymes on the growth of cucumbers was evaluated.The results showed that the homemade agricultural plant enzyme significantly enhanced cucumber growth and development,with varying effects observed at different dilution ratios.The 500-fold dilution of the agricultural plant enzymes demonstrated the most pronounced growth-promoting effect,increasing cucumber stem diameter,leaf area,and chlorophyll content by 23.94%,28.71%,and 46.97%respectively,compared with CK.Additionally,the accumulation of lignin in cucumber seedlings and the activities of key enzymes in the lignin biosynthesis pathway phenylalanine ammonia-lyase(PAL),cinnamyl alcohol dehydrogenase(CAD),and peroxidase(POD)were significantly elevated,increasing by 48.49%,46.73%,54.41%,and 50.87%respectively.Cucumber yield was also significantly improved,with an increase of 19.30%.Agricultural plant enzymes hold broad application prospects in agricultural production,and this study provided a reference for the widespread application of enzymes.
