随着我国现代设施农业的高速发展,在有限土地资源上进行大规模专一作物的连续种植,造成了土壤养分失衡、土壤酸化、次生盐渍化以及土传病原菌大量积累,导致了大面积的连作障碍。针对连作障碍,人们进行了大量研究,如利用土壤灭菌技术、轮作、间作、套作、抗连作品种的选用与嫁接栽培、合理灌溉与施肥、生物防治以及强还原土壤灭菌法等。这些方法虽然均有一定防控效果,但也有不足之处,所以高效、可持续、多功能的防控方法仍然是设施土壤连作障碍防控技术研究重点。
With the rapid development of modern facilities and agriculture in our country, continuous planting of large-scale and specialized crops on limited land resources has resulted in soil nutrient imbalance, soil acidification, secondary salinization and large accumulation of soil-borne pathogens, resulting in a large area Continuous obstacles. A large number of studies have been conducted on crop failure such as soil sterilization, rotation, intercropping, intercropping, selection of resistant continuous cropping and grafting, rational irrigation and fertilization, biological control and strong reduction of soil sterilization. Although these methods all have certain prevention and control effects, they have some shortcomings. Therefore, efficient, sustainable and multi-functional prevention and control methods are still the focus of research on prevention and control of continuous cropping obstacles.
