稻鳖鸭综合种养对稻田杂草影响

Effect of Comprehensive Cultivation and Breeding of Rice-Turtle-Duck on Weeds in Paddy Field

调查了水稻单作和稻鳖及稻鳖鸭共作田间杂草种类、数量及盖度变化。结果显示,稻鳖鸭及稻鳖共作的杂草种类、数量与盖度均显著低于水稻单作,稻鳖鸭及稻鳖共作杂草种类相同,但稻鳖鸭共作其杂草数量与盖度均显著低于稻鳖共作,说明稻鳖共作对田间杂草有抑制作用,田间增加养鸭控制杂草效果更显著。

In this paper,the variety,quantity and coverage of weeds in the field of rice single cropping,rice-turtle and rice-turtle-duck intercropping fields were investigated.The results showed that the weed species,quantity and coverage of rice turtle and rice turtle duck intercropping fields were significantly lower than that of rice single cropping,the species of weeds are the same in rice-turtle and rice-turtle-duck intercropping fields,but the number and coverage of weeds in rice turtle duck co culture were significantly lower than that in rice turtle co culture.The results showed that the rice turtle intercropping could inhibit the weeds in the field,and the effect of raising ducks in the field was more significant.
