摘要
以苗龄三年大田葡萄‘美乐’自根苗为试材,进行草炭、微生物菌剂、草炭+微生物菌剂复合处理,以浇灌清水为对照。结果发现,与对照相比,各处理均提高了葡萄的新梢和叶片的生长、叶片叶绿素含量、光合速率、根系活力以及果实的生长、可溶性固形物的积累与果实着色和香气的合成,以复合处理效果最好,草炭在果实次生代谢方面作用优于微生物菌剂。复合处理的葡萄叶片厚度和叶面积分别比对照增加了50.00%和21.54%,根系活力提高了36.11%,果实的纵径、横径、百粒重及果实可溶性固形物的含量分别比对照增加了10.74%、11.77%、20.12%和10.45%,花色苷、总酚、类黄酮、黄烷醇和单宁分别提高了327.08%、26.90%、51.61%、124.75%和91.67%,己醛、反式-2-己烯醛和反式-2,4-己二烯醛的含量提高了32.24%、44.73%和51.19%。3种处理均改善了土壤的微生物状况,其中复合处理假单胞菌相对丰度最高。综上,以草炭+微生物菌剂复合处理对葡萄的新梢和叶片的生长、叶绿素含量、光合速率、根系活力以及果实的生长、可溶性固形物的积累与果实着色、香气的合成和次生代谢促进效果最好,显著提高土壤有益菌假单胞菌的相对丰度。
3-year-old field Vitis vinifera L‘Merlot'self-rooted seedlings were treated with peat,microbial agents and peat with microbial agents,and the control was irrigated with water.The results showed that compared with the control,all treatments improved the growth of grape shoots and leaves,chlorophyll content of leaves,photosynthetic rate,root activity,fruit growth,accumulation of soluble solids,fruit color and aroma synthesis.The compound treatment had the best effect,and the effect of peat on fruit secondary metabolism was better than that of microbial agents.Compared with the control,the leaf thickness and leaf area increased by 50.00%and 21.54%respectively,and the root activity increased by 36.11%.The longitudinal diameter,transverse di-ameter,100 berry weight and the content of soluble solids in the fruit increased by 10.74%,11.77%,20.12%and 10.45%respectively.The anthocyanins,total phenols,flavonoids,flavanols and tannins increased by 327.08%,26.90%,51.61%,124.75%and 91.67%respectively.The contents of hexanal,trans-2-hexenal and trans-2,4-hexadienal increased by 32.24%,44.73%and 51.19%.All treatments improved the soil microbial status,among which the relative abundance of Pseudomonas in the bacteria of the composite treatment was the highest and significantly higher than that of other treatments.In conclusion,the treatment of peat with microbial agents had the best effect on the growth of grape shoots and leaves,chlorophyll content,photosynthetic rate,root activity,fruit growth,accumulation of soluble solids,fruit color,aroma synthesis and secondary metabolism,and significantly increased the relative abundance of soil beneficial bacteria Pseudomonas.
