菌粮菜间套种植体系对土壤养分状况的影响

THE EFFECTS OF INTENSIVE CULTURE OF EDIBLE FUNGI-GRAIN-VEGETABLE ON THE SOIL NUTRIENTS

试验研究了菌粮菜间套种植体系对土壤养分状况的影响。结果表明,菌粮菜间套种植体系土壤有机质、全氮、水解性氮、速效钾含量有明显增加趋势。土壤速效磷含量低于小麦—玉米地,但较菜园地及春闲地高得多,木耳在田间生长期间,菌块附近土壤的各种养分含量成倍增加。

The effects of intensive culture of Edible fungi-Grain-Vegetable on the soil nutrients had been studied preliminarily. The results showed:In the system of intensive culture of Edible fungi-Grain-Vegetable, the contents of soil organic matter、total and hydrolzable nitrogen, available potash increased significantly. The soil available phosphate was lower than that of wheat-corn rotation land, but higher than that of vegetable land and spring abandoned land. secondly,during the edible fungi growing in field, the contents of soil nutrients increased greatly.
