| Abstract: | The paper studied economical and biological characters of three species of perennial grass and legume (White clover,merit, Ryregrass) between single sowing and mix- sowing in Henan Province. The results showed mixed sown have significant advantage over single sown in controlling weedy plants, enhancing LAL(Leaf area index) and biological yield, which will provide important data for further production of fresh forage and improvement of natural grassland with these grass and legume in Henan. |
