沼液在阳光玫瑰葡萄上的应用效果OA

To achieve scientific utilization of biogas slurry in farmland and precise fertilization,the biogas slurry produced after sufficient fermentation in the anaerobic fermentation device was fed through an integrated water and fertilizer system and dripped on the experimental base of Shine Muscat grape.Four treatments were set up for the experiment:CK(conventional fertilization),and 3 biogas slurry substitution for chemical fertilizer treatments(T1,substitution ratio of 20％;T2,substitution ratio of 35％;T3,substitution ratio of 50％).The results showed that compared with CK,T2 treatment significantly(p＜0.05)increased the single ear weight and the total amount of free amino acid content in the fruits.In terms of soil physical and chemical properties,the T1 treatment could significantly enhance the content of soil organic matter and available phosphorus,incidating that reasonable reduction of chemical fertilizers combined with application of biogas slurry can achieve an improvement in the single ear weight and quality of Shine Muscat grape,while also improving soil quality.
