四分之一世纪以来的科学研究和生产实践证明,在高肥条件下,群体内部光照不足是小麦高产的主要限制因子,适当降低播种量,加大行距,依靠分蘖,即“高肥宽行稀播”是冬小麦高产栽培的发展方向。采用这项技术,冬小麦的亩产量一般都在500kg以上。 为了探索小麦高产栽培途径,1958—1960年在芜湖地区分别在田间和实验室进行了试验。田间试验是在不同的土壤肥力和施肥水平的条件下进行的,供试品种南大2419。 A quarter of a century of scientific research and production practices have proved that in high-fat conditions, the internal light deficit is the main limiting factor for high-yield wheat, the appropriate reduction in seeding, increasing row spacing, relying on tillering, Thin sowing "is the development direction of winter wheat high yield cultivation. With this technology, the yield per mu of winter wheat is generally above 500kg. In order to explore the high-yielding cultivation of wheat, 1958-1960 in Wuhu were tested in the field and laboratory. Field experiments were carried out under different soil fertility and fertilization levels, and the tested varieties Nanda 2419.
