据各地试验:顶凌播种春小麦可以获得较高的产量。一般说,早播比晚播可增产16—30％。例如五寨县孙家坪公社河湾生产队早播的亩产九十二斤,此晚播的亩产七十五斤增产22％,应县南河口公社小石口生产队,早播的亩产二百七十二斤,比晚播的亩产二百三十四斤增产16.2％;晋北农业科学研究所试验,早播比晚播的增产26％……。早播为什么能够增产呢? 主要是因为改变了春麦的生活条件,提高了植栋的生活能力。使之萌动的幼芽在较长时间的低温下,增强 According to tests all over: top Ling sowing spring wheat can get higher yields. In general, early seeding can increase 16-30% than late seeding. For example, Sunjialong commune, Wuzhai County Bay production team early seeding ninety-two pounds per mu, late seeding seventy-five pounds a 22% increase in production, Yingxian Nanhekou Commune Xiaoshuikou team, early seeding per mu two One hundred and seventy catties, an increase of 16.2% over the late-sown mu 234 tons; test of Jinbei Academy of Agricultural Sciences, early sowing 26% more than late sowing ....... Why early planting can increase production? Mainly because of changes in the living conditions of spring wheat, improve the living ability of planting. Germinating sprouts in a longer period of low temperature, enhanced
