Abstract:
【Objective】 Biochar and fly ash on wheat growth and development under the stress of dimetolalin by using them as adsorbents.
【Methods】 Through field potted plants,to study the effects of insect dung sand,three kinds of adsorbent doses of insect dung sand (1,500,3,000 kg/hm
2), biochar (300, 600 kg/hm
2), fly ash (6,000 kg/hm
2) were combined with dodecamethium (150 kg/hm
2), bacterioline (6 kg/hm
2), humic acid (3 kg/hm
2), and herbicides CK and water CK were treated with a total of 25 treatments.
【Results】 The results showed that the inhibition rate of height of medical treatment of 3,000 kg/hm +150 kg/hm was the lowest among all treatment groups, which was -2.99%.The inhibition rate of plant height was -3.10%, which was significantly higher than that of herbicide CK and that of water CK.In terms of stem diameter, 1,500 kg/hm
2 worm sand +150 kg/hm
2 dodecobacterium was the best, and the stem diameter reached 2.56cm.In terms of chlorophyll index, the
SPAD value of 300 kg/hm
2 biochar +6kg/hm
2 bacteria under the field was the highest (45.76), followed by the
SPAD value of 3,000 kg/hm
2 insect dung sand (45.56), both of which were higher than those of the two control groups.The highest single pot yield was 3000 kg/hm
2 insect dung sand, followed by 3,000 kg/hm
2 insect dung sand + Decardiac medicine, which was 60.01% and 54.59% higher than that of herbicide CK.Compared with CK water, it was 52.50% and 47.33% higher.
【Conclusion】 It was shown that the combination of adsorbent and microbe could promote the growth, development and yield of wheat under the stress of dimepenalline.The treatments of 3,000 kg/hm
2 insect dung sand +150 kg/hm
2 twelve fungus medicine and 3,000 kg/hm
2 insect dung sand +6 kg/hm
2 bacteria in the field could significantly increase the plant height of wheat.The effect of dimepenalline on wheat is alleviated.Medical treatment with 3,000 kg/hm
2 insect dung sand and 3,000 kg/hm
2 insect dung sand +150 kg/hm
2 decadicum significantly increase wheat yield.
