叶面喷施沼肥对杏树果实品质的影响研究

为了进一步明确叶面施用沼肥对杏树果实品质的效应,探索在不同施肥时期杏树叶面施沼肥的最佳施用浓度和次数,采用二因素随机区组进行杏树施叶面肥试验。结果表明喷施沼液的浓度对杏树果实单果重、纵横径、果型指数、硬度、可溶性固形物含量、可滴定酸和固酸比影响显著,喷施沼液的次数对杏树果实的单果重、纵横径、硬度和可溶性固形物含量影响显著。得出促进杏树果实品质改善的最优处理为A2B2。即以50%浓度的沼液在展叶期和叶片生长期各喷一次的处理组合效果最佳。

Effect of Anaerobic Fermentation Slurry on Fruit Quality of Apricot

The experiment is to identify the effect of spraying Anaerobic fermentation slurry on fruit quality of apricot trees.To investigate the optimal concentration and times of Anaerobic fermentation slurry on apricot trees during different period.The experiment of spraying Anaerobic fermentation slurry to apricot trees was carried out by two-factor randomized block design. The result shows that different concentrations of Anaerobic fermentation slurry have significant effects on fruit weight,fruit length,fruit width,fruit shape index,firm of fruit,total soluble solids,titratable acids and solid/ acid ratio.Different times of Anaerobic fermentation slurry have significant effects on fruit weight,fruit length,fruit width,firm of fruit and total soluble solids.The optimal treatment which can promote fruit quality is 50%,spraying 1 time on the leaves exhibition stage and on leaves growth stage,respectively.
