Effects of Wheat High-Low Border Cultivation Pattern on the Occurrence of Diseases,Pests and Weeds
Abrasct In order to investigate the effects of different cultivation patterns on wheat diseases,pests and weeds,we set two cultivation patterns(small-flat border cultivation pattern:SFB;high-low border cultivation pattern:HLB)to investigate the occurrence of diseases,pests and weeds under different patterns.The results showed that compared with SFB,the weeds damage of HLB was significantly reduced,the number of weeds was reduced by 22.26％-27.87％,and the fresh weight was reduced by 50.06％-66.94％.Different cultivation patterns had significant effects on the occurrence of wheat aphids,red spiders and wheat sawfly,compared with SFB,the number of red spiders under HLB decreased by 4.65％-28.81％,while the number of aphids and wheat sawfly increased in different degrees.The infection percentage and disease index of wheat sheath blight,wheat powdery mildew and wheat crown rot under HLB were lower than those under SFB.Therefore,HLB pattern has broad application prospects in the well-irrigated areas of Huang-Huai-Hai Plain.Under this pattern,the key attentions should be paid to preventing and controlling diseases and pests such as wheat powdery mildew,wheat aphids,and wheat sawflies,and the monitoring of other diseases and pests also needs to be strengthed.
