试验设置沼液稀释50倍,100倍及对照3个处理,于初果期、幼果期和果实膨大期各喷施1次,结果表明沼液稀释50倍的效果最好。与对照相比,叶片的厚度可增加17.95%,干物重可增加15.43%;叶片中叶绿素和可溶性蛋白含量可分别提高8.99%和8.75%;果实中还原糖、总糖、抗坏血酸和可溶性灰分含量可分别提高17.71%,4.55%,420.15%,58.33%,可滴定酸浓度降低13.29%;单果实重量可增加9.55%,亩产量达2989.17公斤。叶面喷施沼液可以提高叶片的光合作用,提高产量,同时可明显改善果实品质,提高其营养价值。
The experiment set the biogas slurry diluted 50 times, 100 times and the control 3 treatment, in the early fruit stage, young fruit and fruit enlargement of the spray each time 1 times, the results show that biogas slurry diluted 50 times the best. Compared with the control, the leaf thickness increased by 17.95% and the dry weight increased by 15.43%. The content of chlorophyll and soluble protein in the leaves increased by 8.99% and 8.75%, respectively. The contents of reducing sugar, total sugar, ascorbic acid and soluble ash in the fruits were Increased by 17.71%, 4.55%, 420.15% and 58.33% respectively, and the concentration of titratable acid decreased by 13.29%. The weight of single fruit increased by 9.55% and the yield per mu reached 2989.17 kg. Foliar application of biogas slurry can improve leaf photosynthesis, increase yield, at the same time can significantly improve the quality of fruits and improve their nutritional value.
