- Abstract:
- Tomato and different varieties of potato onions were used as the experimental materials.The effects of different varieties of potato onions companion on tomato growth,population density,disease index and incidence rate of tomato root-knot nematode were studied,in order to provide reference for biological control of tomato root-knot nematode.The results showed that companion cropping with different varieties of potato onion had no significant effect on the,aboveground fresh weight,root fresh weight and plant height after planted for 30 days.The ‘M01’‘M07’‘M34’‘M46’‘M40’‘M45’‘M12’‘M14’‘M20’ were so significantly higher than control on soil nematode population after planted for 30 days.During the 60 days of planting,‘M02’‘M04’‘M06’‘M07’‘M08’‘M09’‘M19’‘M20’‘M22’‘M23’‘M25’‘M35’‘M38’‘M39’‘M45’‘M50’‘M51’ were significantly higher than control on soil nematode population,and ‘M12’‘M21’ were significantly lower than control.The ‘M22’‘M08’‘M23’and ‘M38’ 4 treatment were significantly lower than that of the control on decrease rate of soil nematodes,and the other treatments were not significantly than control.The different varieties of potato onions were significantly reduced the root knot index and disease index of the root-knot nematode where between 30%-100%,specially the root index and disease index of ‘M11’‘M28’‘M29’‘M51’ had no disease,significant than the control and other treatments.Different varieties of potato onion associated significantly reduced the incidence of tomato root-knot nematode,‘M29’‘M51’ incidence rate was 333%,significantly lower than control and other treatments after planted for 30 days.In summary,the best potato onion varieties companion cropping with tomato were ‘M11’‘M28’‘M29’ and ‘M51’ for controlling tomato root-knot nematode.
