生物有机肥对"一年两收"葡萄花芽发育与果实品质的影响
Effects of bio-organic fertilizer on flower bud development and fruit quality of"two harvests in one year"grape
摘要
Abstract
[Objectives]This study aimed to evaluate bio-organic fertilization strategies for optimizing flower bud differentiation and fruit quality in Vitis vinifera'Summer Black'under Jiangsu's dual-cropping conditions.By analyzing soil improvement,vine physiology,and fruit quality,an optimal fertilization regime for sustainable nutrient management of"two harvests in one year"was identified.[Methods]Six-year-old'Summer Black'grapes were used as experimental materials.After harvesting in summer and winter,the whole bio-organic fertilizer(T1),Bacillus amyloliquefaciens bio-organic fertilizer(T2)and Trichoderma bio-organic fertilizer(T3)were used as base fertilizers,respectively.At the same time,no fertilization(CK)was used as a control to compare the changes of soil physical and chemical properties,tree growth and fruit quality in the growth cycle of summer and winter.[Results]To a certain extent,different bio-organic fertilizers were beneficial to improving soil nutrients,tree growth and fruit quality,and T2 treatment had the best effect.Compared with CK,the contents of organic matter,alkali-hydrolyzable nitrogen,available potassium in summer and winter fruits of T2 treatment increased by 51.93%-64.46%,45.34%-55.43%and 5.68%-151.04%,respectively.Compared with CK,the length,coarseness and internode length of main shoots in summer and winter fruit growth period increased by 13.47%-53.15%,9.68%-9.83%and 15.93%-17.86%,respectively.In addition,T2 treatment could significantly improve fruit quality.Compared with CK,T2 treatment could make the summer and winter fruit coloring 4-8 days in advance and significantly promote the weight gain of five grains by 17.30%-45.33%,and the yield increase effect was significant.The overall sugar-increasing effects in summer and winter fruits were ranked:T2,T3,T1 treatment.Compared with CK,the total sugar content of fruits treated with T2 in summer and winter increased by 21.96%-50.46%.In addition,the analysis of the expression of genes related to anthocyanin synthesis and metabolism in peel and pulp showed that bio-organic fertilizer treatment up-regulated the expression of VvSUT1,VvSPS,VvAI,VvME,VvF3'5'H,VvUFGT and VvCHI genes,and down-regulated the expression of VvIDH and VvPEPC genes,thereby promoting the accumulation of sugar and anthocyanin and the degradation of acid.[Conclusions]The application of Bacillus amyloliquefaciens bio-organic fertilizer as base fertilizer had the best effect on the improvement of soil nutrients under the cultivation mode of'Summer Black'and"two harvests in one year".This treatment significantly promoted the recovery of tree vigor and greatly improved the quality of'Summer Black'grape fruit.The comprehensive evaluation value was the highest,which was conducive to the development of the cultivation mode of"two harvests in one year"in Jiangsu Province.关键词
