摘要
以湘晚籼13号为栽培品种,采用田间普查法对湖南晚稻稻-鸭-豆栽培田、化学防治田中主要病虫害进行了调查研究。结果表明:稻—鸭—豆种养模式能明显减少褐飞虱、白背飞虱的发生量,提高了天敌对褐飞虱、白背飞虱的控制作用,防治效果优于化学防治;稻—鸭—豆种养模式能减少稻田二化螟、稻纵卷叶螟、纹枯病和杂草的发生,但防治效果低于化学防治。
The main diseases,insects and weeds in fields of rice-duck-Soybean plant breeding model and chemical control farming were investigated through field general investigation,and the Xiangwanxian13 was taken as cultivar.The results showed that the rice-duck-soybean plant breeding model can obviously reduce the amount of brown planthoppers and Sogatella furcifera,enhance the control effect of natural enemies against brown planthoppers and Sogatella furcifera,and the control effect in rice-duck-soybean plant breeding model filed was more obvious than that in chemical control farming field;the rice-duck-soybean plant breeding model also can reduce the occurrence of Chilo supperssalis Walker,Cnaphalocrocis medinalis Guenée,Rhizoctonia solani and weeds,but its control effect was lower than that of chemical control farming.
