Abstract: In order to alleviate the increasingly serious problems caused by continuous cropping in greenhouse vegetables, it is important to study the reduction technological measures of continuous cropping obstacles for the development of greenhouse vegetable industry. According to the basic principles of continuous cropping obstacles technology, 5 aspects were introduced, which included selection of cultivars, grafting seedling technology, agronomic technology, physical technology, rational use of chemical reagents and microbial processing, aiming at providing references for the soil amelioration and improvement of quality and yield. |
