经济和科学技术的飞速发展在一定程度上促进了我国种植业结构的调整,保护地栽培和集约化逐步地成为我国农业发展的新特点。实践证明,保护地栽培能4农民收入快速增加;同时,所栽培的作物由之前较为单一的蔬菜转变为综合性的花卉、苗圃、中草药等方向。但随着保护地的发展,土传病害也变得越来越普遍。基于此,从农业防治技术、化学防治技术和物理防治技术3个方面展开对土传病害无公害防治技术的详细探讨。
The rapid development of economy and science and technology has, to a certain extent, promoted the adjustment of the planting structure in our country. The cultivation and intensification of protected areas have gradually become the new characteristics of agricultural development in our country. Practice has proved that the cultivation of protected areas can rapidly increase the incomes of peasants; at the same time, the cultivated crops have been transformed from the more soley vegetables to comprehensive flowers, nurseries and Chinese herbal medicines. However, with the development of protected areas, soil-borne diseases have become more and more common. Based on this, a detailed discussion on pollution-free prevention and control of soil-borne diseases has been carried out from three aspects: agricultural control technology, chemical control technology and physical control technology.
