采用连续提取法研究了猪粪堆肥处理中重金属浓度和形态的变化以及不同添加比例的重金属钝化剂对其浓度和形态的影响.结果表明:经过堆肥处理后,重金属As,Cu和Zn的浓度普遍升高;堆肥处理能促进重金属As,Cu和Zn的形态向活性降低的方向转化,因此堆肥处理可以降低重金属的生物有效性.在3种重金属钝化剂及不同添加比例处理中,猪粪堆肥重金属As的最佳钝化剂及其添加比例为7.5%的粉煤灰,对可交换态As的钝化效果为51.4%;重金属Cu的最佳钝化剂及其添加比例为2.5%的粉煤灰,对可交换态Cu的钝化效果为29.7%;重金属Zn的最佳钝化剂及其添加比例为5.0%的钙镁磷肥,对可交换态Zn的钝化效果为50.0%.因此,堆肥处理中...

The synthetic chemical,4-（p-acetoxyphenyl）-2-butanone（raspberry ketone acetate,RKA） was used extensively to monitor and control Bactrocera cucurbitae recently.To improve the attraction of attractant,a rotating olfactometer was adapted for laboratory evaluation of the mixtures of raspberry ketone and 4-methoxyphenylacetone,with the similar structure to RKA,and several kinds of esters at a certain ratio.Attraction of male flies to RKA：4-methoxyphenylacetone：butyl acetate=3：1：1 was greater than other formulae.In outdoor trap assays of seve...
