摘要
对比试验结果表明,稻鸭共育对水稻纹枯病、稻飞虱、叶蝉的防除效果显著;对二化螟、稻纵卷叶螟等有一定的控制作用。就防治稻飞虱和杂草而言,稻鸭共育可以替代药剂防治。对天敌虽然有一定程度损伤,但主要天敌蜘蛛的总量仍比常规药剂防治田高1.37～3.10倍,天敌优势种群密度显著高于常规防治田。表明生态治理害虫的效果明显。稻鸭共育还可提高水稻分蘖数,比常规防治区增产8.67%。稻鸭共育生态防治技术是生产AA级绿色食品大米的关键技术措施之一。
Study on co-cultivation technique of raising ducks with planting rices in the production system of AA grade green rice was done. Results showed that the co-cultivation technique had good control effects against rice sheath blight, rice planthoppers, leathoppers, and had some control effects against rice leaf folder, In the cases of controlling rice planthoppers and weeds, the co-cultivation technique were able to replace pesticides. Although it had some negative impacts on natural enemies, the populations of major natural enemy-spiders was increased 1.37 to 3.10 times in the fields where co-cultivation technique was implemented compared with the fields where normal chemical control measures were taken. Siginificnat ecological benefits were achieved by using the co-cuhivaition technique, Rice tillering were increased with a increment of yields by 8.67% by using this co-cultivation tecchnique, thus the co-cultivation technique of raising ducks with planting rices was one of key techniques in the production of AA grade green rice.
