甘肃省河西走廊灌溉麦区野燕麦综合防除研究

The Occuring and Integrated Control of the False Oat Grasses in The Irrigating Spring Wheat Area of Hexi Corridor

野燕麦是甘肃河西走廊灌溉麦区的恶性杂草,1978年危害率90.15％,危害度平均13.13％。1980年以来,采用轮作倒茬、隔期深耕、诱发灭草和使用除草剂进行大面积综合防除,危害程度逐年减轻,1987年危害率降至50.1％,危害度降至0.3％。

The False Oat Grasses is one of the importent weeds in the Dryland aera.lt has been happening in the Hexi corrider, CanSu province, for mang years, and it is particularly harming the Spring Wheat.In 1978, the infecting degree of the False Oat Grasses in the wheat fields arrived at 13.13% .Though it was majority integrated control by chemicals form J980 to 1987 the infecting degree was failed to 0.30%, and the effects is signifficient.This paper was aimed at the biological characters, propating channels, planting quarantines, agricultural controlling and chemical controlling of the False Oat Grasses.And we have report on every point, specially, the integrated control effects of the Barbane was arrived at 97% .
