摘要
以5年生‘赤霞珠’为研究对象,连续2 a(2017、2018年)施用羊粪基有机肥,施用量分别为8、10、12、14、16 t/hm^2,分别记为T1、T2、T3、T4、T5,以不施肥为对照(CK)进行田间试验,探讨羊粪基有机肥对土壤有机碳含量,葡萄产量和品质的影响。结果表明:随着有机肥施用量的提高,土壤有机碳含量呈增长趋势,施肥量为16t/hm^2时,土壤有机碳含量最高,2017、2018年分别比对照增长31.27%、50.51%;施用有机肥对葡萄增产有显著作用,施用量为12 t/hm^2时,2017、2018年葡萄产量和收益均为最高;有机肥对葡萄品质具有改善作用,2017、2018年施用有机肥处理的葡萄的可溶性固形物、还原性糖、可溶性糖、总酚含量均显著高于CK的,2017、2018年有机肥施用量为12 t/hm^2时,葡萄的可溶性固形物、还原性糖、可溶性糖、花色苷、总酚含量均为最高;葡萄的可溶性固形物、还原性糖、可溶性糖、花色苷、总酚含量和产量与土壤有机碳含量呈显著或极显著正相关关系;葡萄产量和土壤有机碳含量的线性回归方程为y=1 442.827x-2 979.933,R^2=0.469。综上可知,施用有机肥可提高土壤有机碳含量,增加葡萄产量,改善果实品质,建议葡萄种植生产中有机肥施肥量为12 t/hm^2。
To explore the effect of organic fertilizer on soil organic carbon content,grape yield and quality,with use of the 5-year-old‘Cabernet Sauvignon’as martial,the organic fertilizer was applied continuously for 2 years(2017,2018),the application rates were 8,10,12,14,16 t/hm^2,marked as T1,T2,T3,T4,T5,respectively.The control(CK)had no fertilization.The results showed that with the increase of organic fertilizer application,the soil organic carbon content showed an increasing trend.When the fertilizer application rate was 16 t/hm^2,the soil organic carbon content was the highest,which increased by 31.27%and 50.51%compared with CK in 2017 and 2018,respectively.The application of organic fertilizer has a significant effect on grape yield increase.When the application rate was 12 t/hm^2,the grape yield and benefit were the highest in 2017 and 2018.Meanwhile,the organic fertilizer has a positive effect on the quality of grapes.When the application rate of organic fertilizer was 12 t/hm^2 in 2017 and 2018,the contents of soluble solids,reducing sugars,soluble sugars,anthocyanins and total phenol of grape were the highest,and the soluble solids,reducing sugars,soluble sugar,anthocyanin,total phenol content and yield of grape had a significant or extremely significant positive correlation with soil organic carbon content.The linear regression equation for grape yield and soil organic carbon content is y=1442.827x-2979.933,R^2=0.469.In summary,the application of organic fertilizer can increase the soil organic carbon content,the yield of grape and the quality of grape fruit.12 t/hm^2 organic fertilizer application in grape production is recommended.
