The effects of chicken litter on Meloidogyne arenaria in tomato plants cv. Rutgers were determined in the greenhouse. Tomato seedlings were transplanted into a sandy soil amended with five rates of chicken litter and inoculated with 2,000 M. arenaria eggs. After 10 days, total numbers of nematodes in the roots decreased with increasing rates of chicken litter. After 46 days, egg numbers also decreased with increasing litter rates. In another experiment, soil was amended with two litter types, N-P-K fertilizer, and the two primary constituents of chicken litter (manure and pine-shaving bedding). After 10 days, numbers of nematodes in roots were smaller in chicken-excrement treatments as compared to nonexcrement treatments. At 46 days, there were fewer nematode eggs in chicken-excrement treatments compared to nonexcrement treatments. Egg numbers also were smaller for fertilizer and pine-shaving amendments as compared to nonamended controls. Chicken litter and manure amendments suppressed plant growth by 10 days after inoculation but enhanced root weights at 46 days after inoculation. Amendment of soil with chicken litter suppressed M. arenaria and may provide practical control of root-knot nematodes as part of an integrated management system.
在温室中测定了鸡粪对罗格斯品种番茄植株上南方根结线虫的影响。将番茄幼苗移栽到添加了五种不同比例鸡粪的沙质土壤中，并接种2000个南方根结线虫卵。10天后，根内线虫总数随鸡粪施用量增加而减少。46天后，卵数也随鸡粪施用量增加而减少。在另一项试验中，土壤添加了两种鸡粪类型、氮磷钾肥料以及鸡粪的两种主要成分（粪便和松木刨花垫料）。10天后，与非粪便处理相比，鸡粪处理的根内线虫数量更少。46天时，与非粪便处理相比，鸡粪处理的线虫卵更少。与未改良的对照相比，肥料和松木刨花改良处理的卵数也更少。接种后10天，鸡粪和粪便改良处理抑制了植株生长，但接种后46天增加了根重。用鸡粪改良土壤可抑制南方根结线虫，作为综合管理系统的一部分，可能为根结线虫提供切实可行的防治方法。
