皖稻77高产优质栽培技术模式研究

Study on Cultivation Pattern of Wandao 77 for High Yield and Quality

皖稻77系安徽省农业科学院水稻研究所选育的高产优质中籼品种。经多年多点试验与示范,表现出优质、高产、生育期适中以及耐肥抗倒、抗病虫能力强等特点。结合大田生产实际,提出适期播种、稀播壮秧、合理密植、平衡施肥、浅水间歇灌溉促控以及病虫害综合防治等优质高产栽培模式。

A medium-maturing indica rice variety, Wandao 77, was characterized by quality grain,high yield, multiple resistance to diseases, suitable growth duration and wide adaptability. Main practice of cultivation pattern for high yield and quality is to raise healthy seeding with more fillers,sparsely transplant with the wider space, control application amount of nitrogen fertilizer at the middle and late stage and increase application amount of potassium, practice the alternative irrigation of wetting and dry to promote the root growth and vigor, and synthetical prevention and control technology of rice diseases and insect.
