摘要
1998～ 1999年 ,在山西临汾就黑色液膜覆盖冬小麦的增产效应及机理进行了研究。结果表明 ,黑色液膜覆盖具有较好的生物学效应 ,促进了小麦的生长发育 ,保障了小麦生长的土壤水分供给 ,较好地协调了旱地小麦的穗数、穗粒数、千粒重 ,使每公顷产量达 2 95 6 .5kg;水分生产效率达到10 .0 5kg/mm ,较对照提高 30 .3%。
Study on the yield improving effects and its mechanism of black fluid film mulched over winter wheat was conducted during 1998～1999 in Linfen Shanxi. The results showed that the application of black fluid film has good biological effect.It stimulated the growth of wheat,ensured water supply of the soil for its growth,and harmonized ear number,spike number and 1 000 seed weight of winter wheat in dry land.The yield reached 2 956.5kg/hm 2,and water efficiency 10.05kg/mm which was 30.3% higher than that of the control.
