补充资料:甜菜地膜覆盖栽培(growing sugar beet with mulching membrane)
甜菜地膜覆盖栽培(growing sugar beet with mulching membrane) 用塑料薄膜覆盖甜菜地,以改善生态条件,促进早发,延长生育期,对增加块根产量和产糖量有着重要作用的一项技术措施。 地膜覆盖除具有增温、保水、改善营养外,还可抑制土壤中的盐碱上升,减轻盐碱为害。 在深松整地基础上,及时耙耢、整平地面,覆膜后用土压严。东北春播区,普遍采取垄作覆膜栽培,选用幅宽60-70cm地膜覆盖。华北和西北甜菜区,采取平作覆膜栽培,选用幅宽1.1m地膜,每幅播种三行,行距40cm,地膜边缘距离苗远15cm,埋入土中的地膜5cm左右,每隔三行甜菜留45cm宽不覆膜,以备取土压膜和田间管理。 甜菜产量高,吸收营养增加,消耗土壤肥力多,一般覆膜地要比未覆膜地施肥量增加30-50%,可保证甜菜丰产,防止早衰。在春季土壤含水量较多和灌溉区,宜先覆膜后播种。一般比正常播期早7天覆膜、提前1-2日播种,以增高表层土壤的温度和含水量,加速种子出苗;土壤干旱、地温低或盐碱地区宜采取先播种后覆膜,比正常播种期提早2-3天。种床土壤疏松,水、温适宜,有利发芽,播种深度略浅,为2-3cm。定植后穴呈凹形,四周突出1.5cm,防止幼苗接触地膜受冻害或被灼伤,促进早发,增强抗寒力。先播种后覆膜的,根据幼苗的长势和天气条件放苗。一般全苗后2-3天开始破膜晾苗,阴天可全天晾苗;晴天,在前一天下午破膜,翌日晾苗。晾苗后,用细土封严晾苗口,防止水分散失或刮风揭膜。在中国东北、华北甜菜区,一般于覆膜后60-70天揭膜,进行追肥和除草中耕、培土等促进块根增长,减少根头高度。在降水量不足地区,揭膜后应及时灌水,满足甜菜需水要求。 |
