贵州开阳县自1985年以来,推广工厂化薄土育秧技术,室内一次成苗直插大田,比原来老法育秧和两段育秧能更有效地克服“倒春寒”气候对水稻育秧的危害,且秧期短(仅15—18天)、稳产高产、省工省种、省秧田,受到普遍欢迎。 Since 1985, Kaiyang County in Guizhou Province has promoted the technology of thinning and planting thin-bed rice in the factory. Once the seedlings are transplanted in the field once, the old law-feeding seedling and the two-stage seedling nursery can more effectively overcome the harm of rice planting in the “late spring and cold” climate and Seedling short (only 15-18 days), stable and high yield, provincial and provincial plant seedlings, province, are generally welcomed.
