土壤熏蒸消毒是森林苗圃防治根部病原真菌、植物寄生线虫、害虫和杂草的重要管理措施。虽然熏蒸消毒多年来就应用于苗圃栽培以防治针叶树苗根部病原体和杂草,但是在生产上对阔叶树苗却没有广泛应用。 求研究1974年开始,测定四种土壤熏蒸消毒剂各用二个比率和一种土壤杀真菌剂的效果:(1)常规栽培下四种阔叶树种的生长;(2)苗床上这些树种内生菌根的发育情况。 Soil fumigation and disinfection of forest nursery root pathogenic fungi control, plant parasitic nematodes, pests and weeds important management measures. Although fumigation disinfection has been applied to nursery cultivation for many years to control the root pathogens and weeds in conifers, it has not been widely used in broad-leaved saplings in production. The study began in 1974, the determination of the four soil fumigation disinfectant with two ratios and the effect of a soil fungicide: (1) Conventional cultivation of four broad-leaved tree species growth; (2) seedbed on the endophytes of these species Mycorrhiza development.
