The effects of soil solarization and ammonium bicarbonate or ammonium sulfate against plant-parasitic nematodes on yellow squash (Cucurbita pepo) and on vinca (Catharanthus roseus) were evaluated at two sites. Solarization for 3 weeks in the spring suppressed population levels of Belonolaimus longicaudatus, Criconemella spp., and Dolichodorus heterocephalus throughout the growing season on both crops at both sites. Levels of Meloidogyne incognita were suppressed initially, but population densities increased by the end of the crop in several cases. In one site, numbers of Paratrichodorus minor resurged following solarization to levels that were greater than those present in unsolarized control plots. The effect of solarization was not enhanced by combination with ammonium amendments, but, in one site, application of ammonium bicarbonate or ammonium sulfate resulted in lower numbers of B. longicaudatus than in the unamended control. Additional research and improved efficacy of candidate amendments are required before they can be successfully integrated with solarization for nematode management. Efficacy of solarization against plant-parasitic nematodes was achieved despite a relatively short (3 weeks) solarization period.
在两个地点评估了土壤太阳能消毒以及碳酸氢铵或硫酸铵对西葫芦（南瓜属）和长春花（长春花属）上植物寄生线虫的影响。春季进行3周的太阳能消毒，在两个地点的两种作物整个生长季节中，均抑制了长针线虫、环线虫属和异头长针线虫的种群数量。南方根结线虫的数量起初受到抑制，但在某些情况下，作物生长季结束时种群密度增加。在一个地点，微小拟毛刺线虫的数量在太阳能消毒后回升至高于未进行太阳能消毒的对照地块。太阳能消毒与铵肥改良剂结合使用并未增强效果，但在一个地点，施用碳酸氢铵或硫酸铵使长针线虫的数量低于未改良的对照。在候选改良剂能够成功与太阳能消毒结合用于线虫管理之前，还需要进行更多研究并提高其功效。尽管太阳能消毒期相对较短（3周），但仍实现了对植物寄生线虫的消毒效果。
