小拱棚及不同基质对马铃薯原原种产量的影响

Effects of Small Arch Shed and Different Substrates on Pre-elite Seed Yield

为了提高马铃薯原原种产量,降低原原种生产成本,就小拱棚及不同基质对马铃薯原原种产量的影响进行研究。选用‘克新2号’和‘青薯6号’脱毒苗为试验材料,采用单因素随机区组设计,分析了小拱棚及不同基质类型对马铃薯原原种商品薯产量和总产量的影响。结果表明,有小拱棚的产量显著高于无小拱棚的;采用"麦壳蛭石=12"的基质商品薯产量最高,其次为"羊粪蛭石=13"的基质,但"麦壳蛭石=12"和"麦壳蛭石=11"的基质商品薯率较高,且成本较低。

The effects of small arch shed and different substrates on pre-elite seed yield were studied to improve pre-elite seed yield, and reduce the production cost of pre-elite seed using the plantlets in vitro of the varieties ’Kexin 2’and ’Qingshu 6’ as experimental materials, respectively. In a randomized block design, the influence of small arch shed and different substrate types on pre-elite marketable tuber yield and total yield were analyzed. The results showed that potato minituber yield under a small arch shed was significantly higher than that of no small arch shed; marketable minituber yield of the substrate formula of ’wheat huskvermiculite’ in the ratio of 1：2 was the highest, followed by the substrate formula of ’sheep dung vermiculite’ in the ratio of 1：3, however, marketable minituber percentage of the substrate formula of ’wheat huskvermiculite’ in the ratio of 1：2 and 1：1 was higher, and the cost was lower.
