旱育秧具有省工、省力、省投入、节水和高产的特点，但有盘抛秧推广成本相对较高。秧龄弹性无法克服，为解决上述矛盾，我所于1999年开展水稻旱育无盘抛秧技术研究，取得一定进展，简报于后。旱育秧选用本所紫色壤上，土质中壤，肥力中上，供试品种11优gus。旱育苗床采用腐熟的 Dry nursery seedlings with labor, labor-saving, provincial investment, water saving and high yield characteristics, but there is discounted rice seedling promotion costs are relatively high. Seedling age flexibility can not be overcome, in order to solve the above contradictions, I carried out in 1999, rice dry cultivation without disk throwing technology research, made some progress, briefing later. Upland seedling selection of the purple soil, soil, fertility, the test varieties 11 gus. Dry nursery bed with decomposed
