On Obstacles and Adjustment measures of Succession Planting Vegetables in Protected Cultivation

从土壤有害微生物增加,土传病虫害加重、土壤养分不均衡、土壤次生盐渍化、土壤酸化和植物自毒作用等方面综合分析设施蔬菜连作的障碍主要原因,提出设施蔬菜连作障碍的调控措施,并论述设施蔬菜连作障碍今后应加强的研究方向。

Main obstacle reasons in soil of succession planting vegetables in protected cultivation were reviewed from soil maleficent microorganism increment, soil-borne diseases and insect pests to aggravation, soil nutrient imbalance, soil hypo-salinization, soil acidification and plant autotoxicity. Therefore the adjustment measures in soil of succession planting vegetables in protected cultivation are brought forward in the paper and future research directions are discussed in obstacles of succession planting of protective vegetable as well.
