摘要/Abstract

摘要： 本文报道了丘陵地区发育于第四纪红色粘土母质的马尾松林自然植被下红壤、栽种胡枝子的两种侵蚀红壤及花生-油菜轮作的耕作红壤等3种生态条件下的土壤中VA菌根真菌繁殖体数量、种类、侵染势、施用石灰石粉改土和增施磷肥对VA菌根真菌侵染的影响以及VA菌根真菌的接种效应.试验结果表明,3种生态条件下的土壤中VA菌根真菌繁殖体数量和侵染势显然不同:马尾松林自然植被下的红壤中VA菌根真菌繁殖体数量大,侵染迅速;花生-油菜轮作的耕作红壤VA菌根真菌繁殖体数量也大,但侵染缓慢,有明显的滞后期;栽种胡枝子的侵蚀红壤VA菌根真菌繁殖体数量小,侵染力很低.对侵蚀红壤与耕作红壤接种VA菌根真菌,显著提高了VA菌根的侵染率,在适当施用磷肥及施石灰石粉改土后,都能促进VA菌根侵染,从而增加了植物的吸磷量,植物生长量显著提高.

Abstract: This paper deals with the infectivity and effectiveness of VAmycorrhizal fungi in red soils derived from quarternary red clay in hilly areas of central China. Propagule number of indigenous VAMfungi in red soils under natural vegetation, planted with upland crops and suffered from erosion was 33, 50 and 2—3 per 100g soil respectively estimated by MPNmethod. Development of infection was paralleled with the population of VAMfungi in soil. There was a lag phase of infection in cultivated red soil and mycorrhizal infection was quite low throughout the whole growing period on eroded red soils. VAMinfection in both cultivated and eroded soils was promoted significantly by mycorrhizal inoculation. Proper liming and phosphorus fertilization also encouraged VAMinfection of plants on both soils, and hence the total amount of phosphorus and plant growth were greatly enhanced.

Key words: VA mycorrhiza, Propagule number, Infectivity, Development of intection, Mycorrhizal response
