| 摘 要： | 作者于１９９８￣１９９９年在国营八五三农场试验站内，采取大面积对比的方法，对大豆覆膜技术增产机理进行了广泛研究。在大豆各生长发育阶段，对大豆生长的环境条件和形态指标进行定点测定。结果表明：覆膜可以明显提高土壤温度，减少水分蒸发，增加耕层土壤含水量，改善根系生长环境；大豆株高，分枝粒数、总荚数，产量都与对照有极显著差异。

| Abstract: | Base on experimental data from 1998 to 1999, the effect of film mulching on soil environment and yield in soybean production was studied. The experiment has been conducted in black soil region in State Farm 853. Results showed that mulching could inerease soil temperature, preserve soil moisture, increase plough layer soil water, create an favorable environment for soybean growth and had obviously effect on yield. |
