虎杖因种子寿命短,保存不易,繁殖上一直依赖分根繁殖。而夏季利用全光喷雾技术繁殖虎杖,给虎杖扩繁提供了良好途径。利用人工全光喷雾育苗床,由草炭土、河沙、蛭石以1∶1∶1比例配成基质,通过嫩枝扦插,配以严格的水分管理和合理的病虫害防治手段,能使每床出苗量5万～6万株,每年繁殖4～5次,大大提高了繁殖效率,为虎杖的大规模生产提供了育苗保障。
Polygonum cuspidula due to short seed life, easy to save, reproduction has been dependent on root and shoot propagation. In summer, all-photon spray technology was used to breed Polygonum cuspidatum, which provided a good way for Polygonum cuspidatum to multiply. Artificial all-optical spray nursery bed, peat soil, river sand, vermiculite ratio of 1: 1: 1 matrix, through the tender cuttings, together with strict water management and reasonable pest control measures, can make each bed Emergence of 50,000 to 60,000, breeding 4 to 5 times a year, greatly improving the breeding efficiency for the large-scale production of Polygonum cuspidatum nursery security.
