chinois. 为水稻机械化直播推广提供技术支持，减轻长江流域春季低温对直播稻芽期的危害，本文研究了液体地膜覆盖对直播稻抵御芽期低温的效果．试验结果表明，水稻芽期液体地膜覆盖有明显的保墒增温作用，采用体积比1：1稀释液体地膜覆盖，湘早籼24号和株两优2号2个水稻品种的成苗率分别比对照提高了19．25％和22．37％，降低了水稻幼苗的株高，增大了叶龄和单位苗高于质量．表明液体地膜覆盖是直播稻栽培中抵御芽期低温的一项有效技术．[著者文摘]

To solve the low-temperature damage and promote the mechanization for direct seeding rice in the Yangtze River area, effects of liquid film mulching on cold resistance of direct-seeding rice at early seedling stage were studied in an artificial climate-room. The results showed that liquid film mulching could effectively increase the temperature and moisture contact in soil. Application of 1 ： 1 dilution of liquid film increased the available seedling rate by 19. 25% for Xiangzaoxian24 and by 22. 37% for Zhuliangyou2 compared with CK respectively, leaf and height. Therefore, the liquid film mulching is dry mass per unit seedling height, and reduced seedling an effective technique in direct-seeding rice production.[著者文摘]
