旱育稀植是水稻高产的一项栽培技术 ,特别是对高寒山区稻田和冷荫烂锈田的水稻生产更具有增产幅度大的作用。为了探索旱秧在不同酸度土壤下的生长素质与调酸技术 ,更好地培育出健壮的秧苗 ,为进一步完善旱育稀植栽培技术提供科学依据。在省农技总站的主持下 ,进行了水稻旱育稀 Drought-fodder planting is a high-yielding cultivation technique of rice, especially for paddy field and cool-shade rust field in the alpine region with more yield-increasing rice yield. In order to explore the growth qualities and acid-adjusting techniques of dry plantlets in different acidity soils, we can cultivate robust seedlings better and provide scientific basis for further improving the cultivation techniques of dry-plant breeding. Under the auspices of the Provincial Agricultural Technology Terminus, carried out arid rice drought
