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。 |
