摘要
通过对20%的辣根素水乳剂进行不同剂量的调制,分析不同药量处理对连作辣椒生长、光合特性以及土壤酶活性的影响。结果显示,施加不同体积质量分数的辣根素水乳剂改善了连作辣椒的生长特性,提高了辣椒株高、茎粗等生物量;同时改善了土壤酶活性,有效提升了连作辣椒的生长活力;不同体积质量分数辣根素水乳剂对土壤及辣椒植株生长的改善能力不同,需要科学调配到最优体积质量分数。
In this study,the effects of different doses of 20%athomin water emulsion on growth,photosynthetic characteristics and soil enzyme properties of continuous cropping pepper were analyzed after preparing the solutions with different doses.The results showed that the growth characteristics and indexes like plant height,stem thick of continuous cropping pepper were improved by applying athomin water emulsion with different ratios of volume to mass.The athomin water emulsion with different ratios of volume to mass also improved soil enzyme activities and promoted the growth vatality of pepper effectively.Since the improvement ability of athomin water emulsion with different ratios of volume to mass on soil and pepper is different,it is necessary to optimize the ratio of volume to mass.
