The Yield-improving Effects of Black Fluid-film Mulched over Winter Wheat in Dry Land |
| |
| Abstract: | 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. |
