葡萄套袋可以明显地改善果实的外观品质,防止病虫害及裂果的发生,减少农药残留,促进果实着色,改善果实风味,便于分期采收,提高果实的耐贮运性。因而极大地提高果品质量,满足市场对高档葡萄商品果的需求。 1 套袋时期 葡萄套袋时期应在谢花后半月以内,尽可能早,不宜过晚;一般在果实坐果稳定、整穗(即将弱花序、病花序等全部疏去,并掐去l/3穗尖,使果穗紧凑)及疏粒结束后立即开始。赶在雨季来临前结束,以防止早期病害及日灼。另外,套袋要避开雨后的高温天气。在阴雨连绵后突然晴天,如果立即套袋会使日烧加重,应过2~3天后,… 相似文献

The storage of spent maitake culture medium (SMCM) under various conditions was investigated as a potential pretreatment of SMCM for increased ethanol conversion. When SMCM was stored at 25°C for 12?weeks, the glucose yield by enzymatic saccharification increased from 22 to 52%. Selective degradation of lignin and hemicellulose occurred in SMCM during storage. The optimal storage temperature of SMCM was at the active growing temperature of maitake mycelium, which is between 25 and 30°C. Storage of SMCM under anaerobic conditions did not increase the glucose yield compared to non-stored conditions. The glucose yield from the SMCM stored for 4?weeks at 25°C was increased by about 30% with either NaOH or vibrating ball milling pretreatment. After 12?weeks of storage, the glucose yield from SMCM without any other pretreatment was higher than that of non-stored SMCM with additional pretreatments. An ethanol yield of 42.1% was obtained from SMCM stored for 12?weeks by simultaneous saccharification and fermentation, which was comparable to yields after NaOH (41.3%) or vibrating ball milling (44.1%) pretreatments. Therefore, storage of SMCM is a very useful pretreatment for bioethanol production. 相似文献
