牛角花齿蓟马对苜蓿传粉作用的研究

在田间采用施药接虫隔离、施药不接虫隔离、不施药隔离、对照(不施药不隔离)4种处理方法,研究了牛角花齿蓟马对苜蓿的传粉作用。结果表明,对照处理苜蓿平均结荚数和平均种子产量均高于其余3个处理,分别为340.33个/10茎枝、0.709 1 g/10茎枝。其次为施药接虫隔离处理,其平均结荚数和平均种子产量分别为57.67个/10茎枝、0.175 7 g/10茎枝,是不施药不隔离处理结荚数和种子产量的16.95%和24.78%,表明牛角花齿蓟马对苜蓿有一定的传粉作用,但是传粉作用很微弱,传粉效率不高。

Study on alfalfa pollination by Odontothrips lati

The alfalfa pollination by Odontothrips lati was studied with 4 treatments(pesticide application Odontothrips lati introduced closure,pesticide application no Odontothrips lati isolation,no pesticide closure,no pesticide no closure) in alfalfa field.The result indicated that the pod number and the seed yield under Treatment 4(no pesticide no isolation,alfalfa field was open) were higher(340.33 pods/10 branches and 0.709 1 g/10 branches).The next was treatment 1(pesticide application Odontothrips lati introduced closure) and its pod number and seed yield were 57.67 pods/10 branches and 0.175 7 g/10 branches respectively,which were 16.95% and 24.78% of treatment 4.The result suggest that Odontothrips lati had certain pollination to alfalfa,but its pollination efficiency was very low.
