两系杂交稻混植共生对产量的影响

EFFECTS OF MIXED PLANTING SYMBIOSIS ON YIELD OF TWO-LINE HYBRID RICE

摘要: 用７个两系杂交稻参与配成了１３个混植共生体（称之为混系稻）比较了混植共生方式对产量的影响，结果表明：混系稻的产量多数人于参配组合之间，但也有少数混系的产量超过参配组合产量的范围，并达到差异显著水平，这表明同一作物的混植共生有互补或互抑作用。

Abstract: Effects of mixture planting symbiosis on yield of 13 mixture planting symbioic colonies(named:mixture line rice) which were mixed by each two of 7 two-line hybrid rices were studied.The results showed the yield of most mixture-line rices lied between two reference combination's yield, but some significantly increased comparing with the reference combination's. It indicated that mixture planting symbiosis in the same crop existed supplementary effects or inhibited effects. As for its law, it was necessary to be further studied, in order to providing a theoretical basis for utilization in production.
